·  Post-maintenance and Replacement of Curtain Walls: Post-maintenance and replacement work of glass curtain walls and decorative components in completed buildings. Fixed rope outlet + precise synchronization adapts to hoisting operations in narrow spaces on building external facades.

·  Hoisting of Steel Structure Building Accessories: Synchronous lifting of light steel components and splicing accessories on the external facades of steel structure factories and venues. Dual rope synchronization ensures horizontal hoisting of components and avoids installation deviations.

·  Precise Traction in Outdoor Projects: Synchronous traction and positioning of decorative components on bridge outer sides and accessories on the external facades of outdoor venues. Stainless steel protection can adapt to the long-term humid and dusty construction environment outdoors.

Fully Customizable Solutions

Based on industrial-grade modular design, this dual drum electric winch supports personalized customization of all parameters. According to the weight, height and construction environment of glass curtain wall hoisting, as well as the actual needs of various outdoor synchronous lifting, the core configuration and performance parameters can be accurately adjusted to create an exclusive, stable, safe and precise hoisting/traction solution.

1. Load and Power Customization

The rated load can be customized according to the weight of curtain wall panels and components, and the power and torque of K series gear motors are optimized synchronously, balancing hoisting power and operation stability to adapt to different hoisting needs from light glass units to heavy curtain wall components; the cable retraction speed can be customized according to the construction rhythm to realize flexible switching between slow and precise hoisting and medium-speed and efficient transfer.

2. Drum and Rope Customization

The drum rope capacity can be customized according to the hoisting height to adapt to the curtain wall hoisting needs of buildings with different floor heights. At the same time, the single-layer rope arrangement structure of grooved drums is optimized to ensure that the retraction and release lengths of the dual ropes are completely consistent; the diameter and material (high-strength wear-resistant/anti-corrosion) of steel wire ropes can be customized to match different hoisting loads and anti-corrosion requirements of outdoor construction, extending the service life of ropes.

3. Limiter and Safety Customization

The sensitivity of the anti-slack rope limiter can be customized according to the requirements of hoisting operations to adapt to the slack rope detection needs of steel wire ropes of different specifications. Additional safety protection devices such as overload alarm and emergency braking can also be added to strengthen the safety of outdoor construction; the limit stroke can be customized to accurately set the upper and lower limit positions of hoisting and lifting, preventing glass damage and equipment failure caused by over-stroke operation.

4. Rope Outlet and Positioning Customization

According to the construction layout of the building external facade, the rope outlet angle and position of the fixed rope outlet device can be customized to realize multi-angle fixed-point rope outlet, adapting to the precise alignment needs of different installation positions of the curtain wall; the fixed structure of the rope outlet device can be optimized to improve the stability of rope outlet during outdoor construction and avoid the impact of steel wire rope deviation on hoisting accuracy.

5. Protection and Adaptation Customization

In addition to the basic IP65 stainless steel protection, enhanced anti-corrosion protection can be customized, with double-layer stainless steel sealing treatment for the motor and reducer, adapting to strong corrosive outdoor working conditions such as coastal areas and high humidity; the adaptive voltage (different voltage levels for single-phase/three-phase) can be customized according to on-site power supply conditions, without modifying the power supply lines of the construction site, and directly connecting to the temporary construction power supply; the equipment installation method (fixed/mobile) can be customized, with a mobile base or fixed bracket matched, adapting to the flexible use of different construction points on the building external facade.

Frequently Asked Questions (FAQ)

1. What is the dual rope synchronization precision of this dual drum electric winch? Can it prevent the tilting of glass curtain walls?

The equipment adopts a grooved drum single-layer rope arrangement + synchronous drive design, with the synchronization precision of dual rope retraction and release length reaching the millimeter level. During hoisting, the dual ropes bear uniform force and lift and lower consistently, which can completely avoid the tilting and swinging of glass curtain walls and heavy components, and fully meet the precise synchronization requirements of curtain wall hoisting.

2. What is the response speed of the anti-slack rope limiter? Can the motor stop immediately after the rope is slack?

The anti-slack rope limiter adopts a high-sensitivity induction design with a slack rope detection response time of ≤0.5 seconds. Once the steel wire rope slack is detected, it will immediately trigger the motor to stop, quickly avoiding the hoisting safety hazards caused by slack rope, and providing active safety protection for the hoisting of fragile glass curtain walls.

3. Can the rope outlet angle of the fixed rope outlet device be adjusted? Can it adapt to the installation needs of different positions of the curtain wall?

Yes. The rope outlet angle of the fixed rope outlet device can be customized and adjusted according to construction needs. At the same time, the rope outlet position and rope outlet port specifications can be customized to adapt to the curtain wall installation needs of different heights and positions on the building external facade, realizing multi-angle fixed-point precise rope outlet.

4. Can IP65 stainless steel protection adapt to the outdoor high salt spray working conditions in coastal areas?

The basic IP65 stainless steel protection can adapt to conventional outdoor wind, rain and dust working conditions. For the strong corrosive environment of high salt spray in coastal areas, enhanced double-layer stainless steel sealing protection can be customized with an additional anti-salt spray coating, which can effectively resist salt spray erosion and ensure the long-term stable operation of the equipment under coastal working conditions.
