The speed difference anti-fall device can quickly brake and lock falling objects within a limited distance, which is suitable for cargo hoisting and protects the life safety of ground operators and the damage of the lifted workpiece. It is suitable for safety protection to prevent the workpiece from being lifted accidentally when the crane is hoisted. It can effectively protect the life safety of ground operators and the damage of the workpiece to be lifted. It is used in metallurgical automobile manufacturing, petrochemical industry, engineering construction, electricity, ships , communications, pharmaceuticals, bridges and other high-altitude workplaces.
So do you know how the speed difference crash arrester works?
When there is no solid structure above the operating point for fixing the safety rope, the working platform cannot be set up temporarily, and it is inconvenient to use the safety belt at the same time, the differential fall arrester can be used, which is also a supplement and improvement to the protection of high-altitude operations. .
The speed difference anti-fall device is mainly composed of a suspension system and an anti-fall braking system. The suspension system is composed of hooks, nylon ropes and telescopic safety ropes. The anti-fall braking system is mainly composed of a shell, a ratchet, a
gahum spring and a pawl.
The speed difference fall arrester uses the falling speed difference of the object to quickly brake and lock the falling object within the set distance. It is required to hang high and use low.
When in use, it only needs to tie the lifting rope to the structure with a solid blunt edge above, and hang the iron hook on the steel wire rope on the fall arrester into the semicircular ring on the safety belt.
Within the service radius, that is, during normal use, the steel wire rope is free to expand and contract by virtue of the internal gahum spring. Under the action of the internal mechanism, the steel wire rope is in a semi tension state, so that the operator can have safety protection.
In case of a slip and fall, the pulling out speed of the safety rope will be significantly accelerated, the internal pawl will jam the fast rotating ratchet wheel, and the power spring will stop expanding and contracting freely, so as to realize automatic locking, so that the pulling out length of the safety rope will not exceed 0.2m, so as not to cause injury to the falling personnel.
When the person stops falling rapidly, that is, the safety hazard is removed, the internal mechanism of the fall arrester is unlocked, the gahum spring is restored to free expansion and contraction, and it will automatically resume work.
The speed difference fall arrester adopts a double locking structure, with stable locking, high safety factor and good reliability, which can effectively solve the accident caused by sudden falling during high-altitude work.
The equipment used in high-altitude work must be qualified. If you want the speed difference anti-fall device to work better, you must choose a better power spring.
