CA-2D Climb Assist —— Safe, Portable and high efficiency

Introduction

3S Lift CA-2D Climb Assist device is used as auxiliary climb device in wind turbine tubular tower. As it’s mainly mounted on the ladder, we also name it as vertical ladder Climb Assist device, called “Climb Assist” for short.

3S Lift CA-2D Climb Assist as the auxiliary climb device, can provide continuous lifting force of 30-50kg for climbers on the inner vertical ladder of wind turbine tower, vertical shaft, which could reduce the load of climbers as well as risk probability resulting from physical tiredness.

3S Lift introduces smart frequency conversion vectorial technology to Climb Assist, which could provide lifting force for both ascending and descending climb according current status of climber, adapt to climber’s speed automatically, convert at any position, retract line automatically, save climbing time, increase working efficiency by more than 3 times. Provide safer, more flexible, more comfortable climbing experience for service personnel.

 

 Advantages

●  Lifting force can be adjusted continuously(continuously adjustable force of 30-50kg

●  Adopting advanced automatic adapting technology, provide safer, more flexible, more comfortable climbing experience for service personnel.

●  Unique speed detection method provides direct, accurate, safe detection.

●  Adopting advanced frequency conversion vectorial technology to realize excellent dynamic
performance, accurate control of moment of force.

●  Unique descending boosting technology provides steady descending boosting force of 30kg to offer comfortable descending climb.

●  Maintenance free design

 

 

Mechanism

●   A circular traction line is driven by electric motor located on the bottom of vertical ladder through the fixed main engine box. The circular traction line is made of wire rope, through the connection of circular sleeve. Driven by bottom driver and guided by top guide wheel, the circular traction line can run continuously.

●   Frequency convertor and smart controller in control box provide proper speed and turning moment for the line driving wheel. Electric control box is assembled by insert-pluck method, which simplifies the structure and enhances product reliability.

●   Operators attach the full body harnesses (conform to EN361) worn to 3S Lift Climb Assist through the fall arrester (conform to EN353). The fall arrest lifeline system (conform to EN353) mounted on vertical ladder can protect operators from high height drop.

 

Components

CA-2D Climb Assist comprises top wheel assembly, guide wheel device, anti-abrasion roller, traction unit, lifting wire rope, electric control box.

Portable control box has one to N function:

Portable control box and fixed main engine adopt cable plug structure to realize prompt connection.

N:indicates one portable control box is available for several tubular tower which own this type of Climb Aid. It is recommended to select 1~5 for N.

The parameters such as lifting power,descending assistant force, protection grade can be customized by 3S Lift R&D team according to customers’ requirements.Please contact our sale commissioneer for more details.
