The real reasons this project required a customized design were the limited space inside the test pool, the possibility of load eccentricity, and the need for precise control.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Together, these conditions led to a customized winch and lifting-system design.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"830\" height=\"399\" src=\"https:\/\/kldwinch.com\/wp-content\/uploads\/2026\/09\/Customized-Winch.webp\" alt=\"Customized Winch\" class=\"wp-image-7944\" title=\"\" srcset=\"https:\/\/kldwinch.com\/wp-content\/uploads\/2026\/09\/Customized-Winch.webp 830w, https:\/\/kldwinch.com\/wp-content\/uploads\/2026\/09\/Customized-Winch-300x144.webp 300w, https:\/\/kldwinch.com\/wp-content\/uploads\/2026\/09\/Customized-Winch-768x369.webp 768w, https:\/\/kldwinch.com\/wp-content\/uploads\/2026\/09\/Customized-Winch-18x9.webp 18w\" sizes=\"auto, (max-width: 830px) 100vw, 830px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>1. Project Overview: Customized Winch for a Laboratory Lifting System<\/strong><strong><\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The project partner was China Aviation Engineering Integrated Equipment Co., Ltd.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">China Aviation Engineering Integrated Equipment Co., Ltd. is a subsidiary of Aviation Industry Corporation of China. Its main business includes equipment design and construction for companies within the group, as well as external design and construction projects.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The final user for this project was Chongqing University. The project involved underwater experiments.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">China Aviation Equipment was responsible for the overall experiment project,while <a href=\"https:\/\/kldwinch.com\/es\/\"><strong><u><strong>KLD<\/strong><\/u><\/strong><\/a>&nbsp;handled the design and manufacturing of the lifting system.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The laboratory lifting system was mainly used to raise and lower a grid-type platform inside the experimental pool. This customized laboratory lifting system was configured for an underwater experiment environment.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Experimental items weighing approximately 20 tons were placed on top of the platform.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">At first glance, this may appear to be a heavy-duty lifting application.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The actual challenges came from the operating conditions.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>2. Why Can\u2019t \u201c20 Tons\u201d Directly Determine the Winch Model?<\/strong><strong><\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Although the experimental items were generally placed at the center of the platform, they could shift to some extent during actual operation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The clearance between the platform and the pool wall was also very small.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This means:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Load eccentricity may cause the platform to shift.<\/li>\n\n\n\n<li>The shifted platform may rub against the pool wall.<\/li>\n\n\n\n<li>In some cases, the platform could even become stuck.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">For ordinary lifting operations, this issue may not need to receive such prominent attention.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Scientific experiments are different.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The operating space, control method, and motion accuracy of experimental equipment must match the specific experimental conditions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Therefore, the core problem in this project was:How could the grid-type platform be raised and lowered more precisely within a limited space?<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This is why the project ultimately adopted a <a href=\"https:\/\/kldwinch.com\/es\/categoria\/productos\/custom-engineered-winches\/\"><u>customized lifting solution<\/u><\/a> consisting of dual drums, fixed pulleys, and servo motors.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"830\" height=\"383\" src=\"https:\/\/kldwinch.com\/wp-content\/uploads\/2026\/09\/Black-Customized-Winch.webp\" alt=\"Black Customized Winch\" class=\"wp-image-7942\" title=\"\" srcset=\"https:\/\/kldwinch.com\/wp-content\/uploads\/2026\/09\/Black-Customized-Winch.webp 830w, https:\/\/kldwinch.com\/wp-content\/uploads\/2026\/09\/Black-Customized-Winch-300x138.webp 300w, https:\/\/kldwinch.com\/wp-content\/uploads\/2026\/09\/Black-Customized-Winch-768x354.webp 768w, https:\/\/kldwinch.com\/wp-content\/uploads\/2026\/09\/Black-Customized-Winch-18x8.webp 18w\" sizes=\"auto, (max-width: 830px) 100vw, 830px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>3. What Technical Requirements Did the Customer Specify?<\/strong><strong><\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">According to the project information, the customer\u2019s requirements focused on several areas.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>1. Dual-drum design<\/strong><strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The lifting system used a dual-drum structure based on the actual operating requirements.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>2. Fixed-pulley arrangement<\/strong><strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Each rope was equipped with two fixed pulleys. These pulleys worked with the wire rope to create the required lifting-system layout.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>3. Servo-motor control<\/strong><strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The main output used a servo motor connected to the customer\u2019s final control system to achieve precise control.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>4. Matching error between the motor and gearbox<\/strong><strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The customer placed particular emphasis on this issue.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The experimental site required high precision, and the platform was positioned close to the pool wall. Therefore, coordination among the motor, gearbox, and subsequent lifting movements was critical.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In other words, the customer did not need a simple \u201cheavy-duty winch.\u201d The requirement was a lifting system matched to the experimental operating conditions.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>4. Technical Parameters That Shaped the Winch Design<\/strong><strong><\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The table&nbsp;show the design direction of the equipment.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Key parameter<\/strong><strong><\/strong><\/td><td><strong>Drawing specification<\/strong><strong><\/strong><\/td><td><strong>Why it matters<\/strong><strong><\/strong><\/td><\/tr><tr><td>Servo-motor power<\/td><td>1,5 kW<\/td><td>Provides driving force for the lifting mechanism and supports the project\u2019s precise-control requirements<\/td><\/tr><tr><td>Gearbox reduction ratio<\/td><td>5944:1<\/td><td>Reduces output speed and increases output torque through a high reduction ratio<\/td><\/tr><tr><td>Rated output torque<\/td><td>54,494 N\u00b7m<\/td><td>Provides substantial output torque for the winch mechanism<\/td><\/tr><tr><td>Velocidad de la cuerda<\/td><td>0.06\u20130.4 m\/min<\/td><td>Low-speed operation supports controllability during the lifting process<\/td><\/tr><tr><td>Lifting stroke<\/td><td>4 metros<\/td><td>Corresponds to the project\u2019s actual lifting and lowering requirements<\/td><\/tr><tr><td>Wire-rope diameter<\/td><td>12 mil\u00edmetros<\/td><td>Matches the drum, pulleys, and overall lifting structure<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">The winch configuration prioritized controlled low-speed movement over high-speed lifting.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The rope speed of 0.06\u20130.4 m\/min, combined with a servo motor and a high reduction ratio, places greater emphasis on control at low speed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That design corresponds directly to the project\u2019s actual requirements.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Because the clearance between the platform and pool wall was small, any significant deviation could cause friction or even jamming.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For this type of laboratory lifting system, capacity is only one check. The lifting process also has to follow the required control method and movement accuracy.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Nota:<\/strong>&nbsp;Project information states that the experimental items weighed approximately 20 tons, while the technical drawing clearly specifies a winch lifting capacity of 2,000 kg. These figures cannot be treated as equivalent. Therefore, this article does not describe the equipment as a \u201c20-ton winch.\u201d<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>5. Why Use a High Reduction Ratio in a Servo Winch?<\/strong><strong><\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">This is an important point that deserves separate explanation.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"821\" height=\"343\" src=\"https:\/\/kldwinch.com\/wp-content\/uploads\/2026\/09\/High-Reduction-Ratio-in-a-Servo-Winch.webp\" alt=\"High Reduction Ratio in a Servo Winch\" class=\"wp-image-7941\" title=\"\" srcset=\"https:\/\/kldwinch.com\/wp-content\/uploads\/2026\/09\/High-Reduction-Ratio-in-a-Servo-Winch.webp 821w, https:\/\/kldwinch.com\/wp-content\/uploads\/2026\/09\/High-Reduction-Ratio-in-a-Servo-Winch-300x125.webp 300w, https:\/\/kldwinch.com\/wp-content\/uploads\/2026\/09\/High-Reduction-Ratio-in-a-Servo-Winch-768x321.webp 768w, https:\/\/kldwinch.com\/wp-content\/uploads\/2026\/09\/High-Reduction-Ratio-in-a-Servo-Winch-18x8.webp 18w\" sizes=\"auto, (max-width: 821px) 100vw, 821px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">The table shows:1.5 kW servo motor + K- and R-series combined gearbox<br>Reduction ratio: 5944:1<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The final rope speed indicates that the system was clearly not designed for high-speed operation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The winch rope speed was only:0.06\u20130.4 m\/min<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For experimental equipment, this low operating speed has a direct benefit:It leaves more room for control and adjustment.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This is especially important when the platform is close to the pool wall. If the lifting process is too fast, the system has less time to correct any deviation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Therefore, the reduction system was not added merely to make the motor rotate more slowly. It formed part of the overall drive solution.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Based on the available case information, the complete dynamic-design process corresponding to this reduction ratio cannot be derived. This article therefore does not extend into unsupported calculations.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>6. Why Load Eccentricity Was the Main Design Risk<\/strong><strong><\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The most important design point was the possible load eccentricity, rather than the headline load figure or motor rating.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It would be:Eccentricity.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The case information clearly states that the experimental items were generally placed at the center of the platform, but some deviation was possible.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The platform was also positioned close to the pool wall.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If lifting continued after eccentricity occurred, the platform could rub against the wall or even become stuck.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For this reason, the customer placed particular emphasis on the matching accuracy between the motor and gearbox.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This requirement reflects an i<strong>mpor<\/strong>tant characteristic of engineering projects:Equipment design must account for unusual conditions that may occur on site, not only normal operating conditions.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Therefore, the Tianheng Kairui engineering team completed calculation and verification before machining began<\/h2>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>7. How the Dual Drums, Fixed Pulleys, and Servo Drive Form One System<\/strong><strong><\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The equipment functions as one coordinated system, with each component assigned a specific role in the lifting path and control sequence.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Dual drums<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Address the structural layout of the lifting system.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Fixed pulleys<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Work with the wire ropes to establish the lifting path.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Servo motor<\/strong><strong><\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Provides the driving force and supports precise control.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Caja de cambios<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Transmits power and matches speed and torque.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Customer\u2019s control system<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Integrates the lifting equipment into the control system for the entire experiment project.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Therefore, the final delivery was not an isolated \u201cwinch.\u201d It was a non-standard lifting system designed around the requirements of the experimental project.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This is why two winches with similar basic functions can require completely different engineering solutions.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>8. Why Laboratory Projects Depend on System Matching<\/strong><strong><\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Ordinary material lifting can often follow this selection process:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Load \u2192 Speed \u2192 Stroke \u2192 Model selection<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Scientific experimental equipment usually requires additional conditions:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Load condition<br>\u2193<br>Equipment space<br>\u2193<br>Lifting object<br>\u2193<br>Wire-rope and pulley arrangement<br>\u2193<br>M\u00e9todo de accionamiento<br>\u2193<br>Control accuracy<br>\u2193<br>Connection with the experimental system<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This project provides a clear example.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Knowing only that the experimental items weighed approximately 20 tons was not enough to determine the complete laboratory lifting-system solution.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It was also necessary to understand:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The structure of the platform<\/li>\n\n\n\n<li>The surrounding space<\/li>\n\n\n\n<li>Whether eccentric loading could occur<\/li>\n\n\n\n<li>The specific requirements of the control system<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>9. Which Projects Suit a Customized Winch and Non-Standard Lifting System?<\/strong><strong><\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Based on the design approach used in this case, customized winches, non-standard winches, and servo winches are more suitable for engineering scenarios where standard equipment cannot be matched directly.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Examples include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Scientific research equipment<\/li>\n\n\n\n<li><a href=\"https:\/\/kldwinch.com\/es\/cabrestante-electrico-rapido-de-alta-velocidad\/\"><strong><u><strong>Laboratory lifting systems<\/strong><\/u><\/strong><\/a><\/li>\n\n\n\n<li>Underwater experiment projects<\/li>\n\n\n\n<li>Large-equipment lifting and lowering<\/li>\n\n\n\n<li>Equipos de automatizaci\u00f3n no est\u00e1ndar<\/li>\n\n\n\n<li>Specialized engineering lifting equipment<\/li>\n\n\n\n<li>Projects requiring precise operation<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">One point must be emphasized:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The need for customization is not determined solely by whether the tonnage is large.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If the site has unusual requirements concerning space, structure, control method, or operating conditions, non-standard design may be necessary even when the load is not particularly large.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>10. Main Lesson: Select a Customized Winch by Operating Conditions, Not Tonnage<\/strong><strong><\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The original question can now be answered from the system conditions:Why does a 20-ton experimental load still require a customized lifting system?<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The answer is clear.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The project had to address more than load weight.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It also involved:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The lifting object inside the experimental pool<\/li>\n\n\n\n<li>The small clearance between the platform and pool wall<\/li>\n\n\n\n<li>Possible load eccentricity<\/li>\n\n\n\n<li>A dual-drum structure<\/li>\n\n\n\n<li>Fixed-pulley arrangement<\/li>\n\n\n\n<li>servoaccionamiento<\/li>\n\n\n\n<li>Low-speed precision control<\/li>\n\n\n\n<li>Matching accuracy between the motor and gearbox<\/li>\n\n\n\n<li>Integration with the customer\u2019s control system<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">These operating conditions collectively determined the final equipment solution. They also explain why a customized winch was selected for the underwater experiment lifting system.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Therefore, when selecting a winch, customized winch, or laboratory lifting system, do not begin by asking:&nbsp;\u201cDo you have a 20-ton winch?\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">First clarify several key questions:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>What needs to be lifted?<\/li>\n\n\n\n<li>How will it be lifted?<\/li>\n\n\n\n<li>How much space is available?<\/li>\n\n\n\n<li>Could the load become eccentric?<\/li>\n\n\n\n<li>What lifting speed is required?<\/li>\n\n\n\n<li>What control accuracy is required?<\/li>\n\n\n\n<li>Must the equipment connect to an existing control system?<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Only after these details are clear can a lifting solution suitable for the site be determined.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Conclusi\u00f3n<\/strong><strong><\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Equipment customization is often not intended to make parameters larger. Its purpose is to match equipment parameters to actual operating conditions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In the Chongqing University underwater experiment project, the approximately 20-ton experimental load was only one background condition.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The factors that truly affected the lifting-system design were the experimental-pool environment, platform structure, possibility of eccentric loading, and precise-control requirements.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The final solution used dual drums, fixed pulleys, a servo motor, and a combined gearbox. Before machining began, the team calculated and verified the matching accuracy between the motor and gearbox.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For non-standard lifting equipment, a good solution is not the one with the largest parameters. It is the one that matches the operating conditions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Pure mechanical logic.&nbsp;No sensors. No power supply. No control system<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>11. FAQ: Customized Winch Design for Laboratory Lifting Systems<\/strong><strong><\/strong><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Q1: Why can\u2019t a 20-ton experimental load be handled by a 20-ton winch?<\/strong><strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The weight of the experimental load cannot be directly equated with the lifting parameter of a single winch.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In this project, the experimental items weighed approximately 20 tons, while the winch technical drawing specified a lifting capacity of 2,000 kg. These are parameters at different levels. Therefore, it is incorrect to interpret them simply as \u201c20-ton experimental load = 20-ton winch.\u201d<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Q2: Why did this equipment use a dual-drum design?<\/strong><strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The dual-drum design was determined by the customer\u2019s actual operating requirements.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The lifting object was a grid-type platform inside an experimental pool. The drums, wire ropes, and fixed pulleys had to be arranged as an integrated system according to the on-site lifting structure, rather than by using a standard single-drum winch.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Q3: Why were two fixed pulleys configured for each rope?<\/strong><strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The case information clearly states that each rope used two fixed pulleys.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">They worked with the drums and wire ropes to establish the complete lifting-system arrangement, ensuring that the equipment structure matched the actual operating method on site.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Q4: Why did this customized servo winch use a 1.5 kW motor?<\/strong><strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The technical drawing shows that the equipment used a 1.5 kW servo motor with a brake.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The project required precise control of the experimental process. Therefore, the main output used a servo motor connected to the customer\u2019s final control system.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The design focus was not simply to use a motor with greater power. It was to match the drive and control system to the actual lifting conditions.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Q5: What is the significance of the 5944:1 reduction ratio?<\/strong><strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The technical drawing specifies K-series and R-series combined gearboxes with a reduction ratio of 5944:1.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Combined with the equipment\u2019s rope speed of 0.06\u20130.4 m\/min, this indicates that the system emphasized control during low-speed lifting rather than high-speed operation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The case information does not provide the complete dynamic calculations. Therefore, no further design conclusions can be derived from this parameter alone.<\/p>","protected":false},"excerpt":{"rendered":"<p>A single load figure does not define an experimental lifting system. \u201cThe experimental load weighs approximately 20 tons.\u201d The practical question is how to choose the winch and system configuration.
