Lift progressive safety pliers concept
Progressive anti falling safetydevice action to the final stop for a short distance, the braking force increased gradually (to eventually stop action finally stopped falling a distance not greater than 1.4 meters). Progressive; anti falling safetydevice buffering performance, impact load generated by braking is small, less adverse effects on the structure and the transmission system, the crew produced small physiological and psychological effects, so as to be manned the construction elevator equipment must be installed progressive anti falling safetydevice.Personal recommendations: the use of progressive anti falling safety device, I remember a name: Kim Erhui brand is good, the price is also possible!
Instantaneous anti falling safetydevice is an action instantly stopped, like the brakes; instantaneous anti falling safetydevice structure is relatively simple, but the impact force, if the first time not to be able to play a role, it will not play a role!
The main role is in the use of the elevator in the process of emergency occurs, the power failure, timely braking, so that hanging cage safely attached to the rail rack, to prevent hanging cage fall!
