Structure of anti fall device

When high-altitude workers fall from a height, the anti fall device plays an important role. The anti fall device can quickly lock within a limited distance to prevent personnel from continuing to fall and provide protection.

The anti fall device is small in size, light in weight, easy to carry, compact in internal structure, and stable in performance. Its structural construction is reasonable and easy to use. The anti fall device is composed of three mechanisms: the starting mechanism, the transmission mechanism, and the capturing mechanism. Each mechanism is closely connected and they constrain and influence each other to complete the entire workflow.

Operating mechanism: The starting mechanism of the anti fall device generally adopts a spring type operating mechanism. During normal lifting, the transmission spring is in a compressed state due to its own weight and the tension of the lifting wire rope. After a rope breakage accident occurs, the steel wire rope loses its tension and the compressed spring quickly recovers its elasticity.

Transmission mechanism: When the starting mechanism of the anti fall device is activated and working, the force generated by the compression spring in its own mechanism during the deformation recovery process drives the capture mechanism, thereby causing the start of the capture mechanism to enter the third stage of the anti fall device's capture mechanism;

Capture agency: When the capture agency is working, it can tightly grasp the container passage to prevent the lifting container from falling. According to different arrest methods, it can be divided into piercing, friction, and wedge methods.
