Climbing Assistance for Improved Health & Safety

The Climb Assist provides a constant lifting force during tower ascent and descent, significantly reducing fatigue and strain.

Climbing assistance for improved health & safety

Improving Health & Safety

The repetitive motion of climbing the turbine tower is not only time-consuming and strenuous. It is also responsible for countless soft tissue injuries. The resulting sick leave and reduced employee motivation can stress the efficiency of the project.

Our Climb Assist provides a constant lifting force during tower ascent and descent, significantly reducing fatigue and strain. This boosts health and safety while also augmenting employee satisfaction and retention.

Automatically Adapts to the Climber’s Speed

The 3S Lift Climb Assist features an advanced design that automatically adapts to the climber’s speed. Variable-frequency vector control assures precisely attuned assistance, whether climbing up or down the tower. No manual operation is required to start or stop the system, allowing the operator to always maintain a safe hold on the ladder.

Retrofit in 3 Hours or Less

The 3S Lift Climb Assist can be easily retrofitted to any turbine ladder in less than three hours. It is easy to install and maintain, providing a low-cost solution for climbing assistance.

Installations Worldwide

The Climb Assist is CE and UL certified and trusted by customers around the globe. Highly valued for its safety, reliability, and ease of use, the 3S Lift Climb Assist has been installed in turbines worldwide.

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.



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.
