 Production  Description

 SAJ40 for safety device (30) belongs to the speed control of incremental for safety device, is the guide frame is equipped with rack construction lifter to prevent falling hoisting cage safety device, it can limit the hanging basket overspeed, effectively prevent the hoisting cage fall accidents. The device is mainly composed of the gear, centrifugal speed limiter and cone drum brake, when construction lifter lifting line speed to achieve the calibration action speed, the centrifugal speed limiter to jilt block shift (quite a pawl), drive the cone drum (ratchet) to the belt movement, by compressing the disc spring in security, the cone drum brake and brake belt joint w of contact friction braking force increases gradually, will eventually hanging basket brake to stop the guide frame, thus ensuring the life of the relevant personnel .

For safety device is one of the important safety device on the construction lifter, after the hoisting cage brakes brake failure due to various reasons, for safety device of construction hoist the safe use of significant, as a way to determine for performance. Hanging basket accelerated decline, speed increases to a certain degree, which play a role for safety device will be hanging basket braking, prevents the hoisting cage fall accidents, ensure the life safety of the crew for safety device on the action itself will be hanging basket to stop on the rail, then used to determine its stopping distance, may cause for safety device testing qualified safety device in excessive technical parameters in the process of drop test
