Climbing assistance for working at height
As an auxiliary climbing equipment, the Climb Assist can provide a continuous lifting force of about 30-50kg for the climbing personnel of the wind power tower, reducing the climbing intensity and reducing the risks that may be caused by physical exertion.

Key Features
- Advanced Speed-Adapting Technology
Equipped with advanced speed adapting technology, the Climb Assist provides steady assistive force, adapting dynamically to the climber’s speed. - Variable-Frequency Vector Control
Variable-frequency vector control enables excellent dynamic performance and comfortable assistant force. - Ascent Assistance
The Climb Assist offers a constant lifting force of 30–50 kg (65–110 lbs) during ascent, which can be easily adjusted based on the operator’s weight. - Descent Assistance
The Climb Assist provides a steady lifting force of 30 kg (65 lbs) during descent. This reduces stress on the body, especially on the knees and ankles. - Optional: Full Cycle Model
The Climb Assist is also available as a full-cycle model (CA-2E), which enables a quicker transition between operators. Once the first operator is done climbing, the second operator can clip onto the wire rope anywhere and begin ascent immediately, without having to wait for the return of the connection point. - Top Sheave
The top sheave fits between the top two rungs, thus minimizing required installation space. - Traction Wire Rope
The traction wire rope is made of steel, providing safe and reliable performance in addition to extraordinary durability. - Control Box
The lightweight control box is waterproof and vibration-proof. It features an industrial cable plug for convenient and quick connection. If desired, it can be used as a portable device to support multiple Climb Assist units. - Motor
The motor provides a continuous lifting force of 30–50 kg. - Minimal Maintenance
The drive and the control box are designed to require no annual maintenance, reducing the overall maintenance time of the Climb Assist to a minimum.
