1.The power supply is suddenly failure
In case of sudden power failure during construction of swing cradle, the power switch of electric box should be cut off immediately to prevent accidents when power is delivered. The power switch of electric swing cradle should be closed until the power is on, and the work must start after normal inspection. If it is necessary to return to the ground after power failure, the manual sliding handle of the mechanical and electrical machine at both ends of the construction hanging platform should be lifted at the same time to make the hanging platform slide freely to the ground.
2.The lifting and lowering process of the swing cradle cannot be stopped
If the suspension platform cannot stop after releasing the button in the process of lifting and lowering, the red tight stop switch on the electric box door should be immediately pressed to make the suspension platform stop in an emergency. Then cut off the power switch of the electric hanging platform, check the contact situation of the contactor, clean up the adhesion of oil and dirt on the surface of the contactor, close the power switch when the contactor can return to normal operation, and rotate the tight stop switch to restore the construction swing platform to its original position and continue to work. If the fault still cannot be resolved, the power switch should be cut off, and the suspension platform should be lowered to the ground by manual sliding method for maintenance.
3.Safety locks do not need manual operation
Its function is that when the lifting system breaks down and the hanging platform over speeds, it can automatically lock on the safety wire rope, so that the electric hanging cradle stops falling to ensure safety. When the fault is eliminated and the safety lock needs to be opened again, the hanging cradle should be raised to make the safety lock slightly loose before the handle can be pulled to open the safety lock. It is forbidden to rigidly pull the opening handle in case of tight safety wire rope to avoid damaging the safety lock. Do not drive the machine down after the safety lock is closed, which can easily cause serious damage to the high rise suspended platform.
