Construction hoist procedures
1, focus on
examination of the job before the project shall meet the following
requirements:
1) the structure of the various parts without deformation, no loose bolts;
2) rack and pinion, guide wheels are engaged with the guide rail is normal;
3) fixed rope ministries good, no abnormal wear and tear;
4) within the operating range of accessibility.

4) within the operating range of accessibility.
2, before the start, you should check that the cable, the ground wire is
intact, the control switch in
the zero position.
3, the operator
should operate in accordance with the command signal. Song before the job
should indicate. Before the lift is not cut off the power switch, the operator
shall not leave the operating positions.
4, when the
elevator is running an abnormality is detected, immediately stop and take
effective measures cage down to the bottom of the ladder, can continue to run
after troubleshooting
5 lifts heavy
rain, fog, high winds and more than six and rack rails, cables and other
frozen, must be stopped and dropped to the bottom of the ladder cage, cut off
the power.
6 lifts run to the uppermost
or lowermost layer, the non-use as a travel
limit switch stops operation
control switch.
7, when the elevator is running due to a power failure or other reasons stopped halfway, you can manually decline, the motor end of the brake release solenoid manually pull out the handle slowly, slowly decline line of the ladder cage. When the ladder cage fell, shall not exceed the rated speed, manual drop must be manipulated by qualified service personnel.
After the operation, it should be dropped to the bottom of the ladder cage, each of the control switch to the zero position, cut off the power lock switch boxes, locking ladder and envelope kennel door.
