Which Ropes Are Recommended for Electric Ascenders?
Not all Type A static ropes conforming to the EN 1891 standard are necessarily compatible with electric ascenders. Given the specific nature of electric ascenders used for personnel lifting, all ropes intended for use with them must undergo valid testing to determine compatibility and ensure the safety of workers at height.
Extensive testing has shown that ropes with a relatively tight braid construction exhibit less radial deformation under the same load when used with electric ascenders. This results in greater friction between the rope and the ascender's sheave, allowing the rope to run smoothly within the device. Conversely, ropes with a looser braid construction experience greater radial deformation under load, leading to reduced friction with the sheave. This can cause two main issues: first, the rope is prone to slipping within the sheave; second, the rope may not feed smoothly out of the sheave, potentially causing pile-up inside the device, which can damage both the rope and the equipment.
Based on the electric ascender rope suitability testing methodology and extensive tests, which ropes are recommended for electric ascenders? The following ropes are recommended for users of electric ascenders working at height:
The JIAOLONG brand static rope utilizes a 32-strand sheath braiding technique combined with a special triple-braided core. This specific triple-braided core structure, along with meticulous production process control, effectively distributes applied external forces. It provides breaking strength far exceeding the average, and maintains a compact structure when used with various types of hardware, offering more stable control. The high-quality polyester fiber sheath enhances the rope's resistance to oil and chemical corrosion, making it more suitable for use in various harsh environments.
JIAOLONG static ropes are suitable for devices conforming to EN 341:2011.
Perfect integration with devices provides higher braking force.
Specially treated for softness, improving comfort during use.
Resistant to oil and chemical corrosion.
Features a special triple-braided core structure.
