I. Project Background and Core Challenges

Project Overview

Customized umbilical cable winch system for a Dubai-based manufacturer of skyscraper window-cleaning robots. The client provides cleaning robot solutions for globally renowned skyscrapers, requiring two rooftop-mounted winches to deliver high-pressure water supply, 220V power, and real-time communication while synchronizing with the robot's aerial lifting operations. Installed atop high-rise buildings, both winches must operate in sync with robots ascending/descending hundreds of meters while withstanding Dubai's extreme outdoor conditions of high temperatures and strong winds.

Core Challenges

1️⃣ Dual Cable Synchronization Difficulty

Traditional winches lack synchronized control mechanisms. As cables and water hoses retract/deploy asynchronously, entanglement and abrasive damage frequently occur. During robot elevation, even slight speed discrepancies between the two independent winches can cause cable entanglement or snapping—posing significant safety hazards at hundreds of meters above ground.

2️⃣ Installation Space & Load Capacity Constraints

Conventional steel winches are heavy, placing substantial load on rooftop installations and complicating transportation. Installation on high-rise rooftops demands efficient use of premium space, where traditional equipment struggles to fit within confined areas.

3️⃣ Inflexible Speed Adjustment

Fixed deployment speeds cannot adapt to the robot's operational rhythm, compromising cleaning efficiency and equipment stability. Winches fail to respond in real-time when the robot's lifting speed changes.

4️⃣ Simplistic Cable Management

Long-distance operations often suffer from signal interference and power interruptions. Conventional winches feature rudimentary cable management, leading to tangled layers and snagged cables during multi-level deployment. This causes cable compression damage, disrupting normal robot operation.

5️⃣ Poor Environmental Adaptability

Equipment must endure prolonged exposure to high-altitude winds, temperature fluctuations, and weathering. Conventional devices lack corrosion resistance and high-temperature tolerance, rendering them unsuitable for long-term outdoor operation.

II. Core Technical Requirements

Following multiple technical discussions, the client specified the following requirements:

Synchronization Accuracy: Dual winches must achieve precise synchronized lifting/lowering, with deployment/retraction speeds dynamically synchronized to robotic movements without noticeable deviation.

Drive Control: Utilize servo motor drive + PLC programming control to ensure operational precision, enabling integration with robotic control systems.

Tension Capacity: Cable winch rated at 40kg pulling force to meet robot power supply and communication needs.

Speed Adjustment: Stepless adjustment from 0.1-0.4m/s to accommodate varying lifting speeds.

Lightweight Design: Equipment must be lightweight for manual rooftop handling, installation, and debugging, with self-weight under 50kg.

Environmental Adaptability: Corrosion-resistant and high-temperature tolerant for sustained outdoor operation.

Customization Capability: Cable length and drum specifications can be tailored to building height, with reserved expansion space for compatibility with various robot models.

V. Design Highlights

✅ Full Aluminum Alloy Lightweight Body

Constructed entirely from high-strength aluminum alloy, the unit weighs only 40kg, balancing strength with lightweight design. Corrosion-resistant and heat-tolerant, it is suitable for long-term outdoor operation on rooftops, significantly reducing installation load pressure.

✅ Precise Synchronized Control

Equipped with a 1.2kW servo motor paired with a 60:1 reduction ratio and PLC closed-loop control, the dual winches achieve high synchronization precision. They dynamically adjust to robotic movements in real-time, ensuring smooth operation.

✅ Anti-Tangling Cable Management

Standard reciprocating lead screw cable guides enforce multi-layer, orderly cable routing. This eliminates tangling and pulling issues in aerial pipelines at the source, guaranteeing uninterrupted power supply and communication.

✅ Easy Installation & Maintenance

Polyurethane swivel casters at the base facilitate positioning without heavy lifting equipment, enabling single-person setup and commissioning. Modular design simplifies replacement of wear parts, minimizing operational costs.

✅ Stepless Speed Adjustment

Cable release speed is steplessly adjustable from 0.1–0.4 m/s, precisely matching robot lifting rhythms to enhance cleaning efficiency and equipment stability.

✅ Customizable Adaptation

Cable length and reel specifications can be adjusted as needed to accommodate varying building heights and robot models. Standard communication interfaces are reserved for high versatility.
