The electrical system of construction lifts is well managed and the equipment can run without any worries.

Construction lifts have also become construction elevators, which are indispensable equipment for vertical lifting of people and goods in modern buildings. The electrical system of a construction lift is very important to the equipment itself. Today, the editor has summarized for you the tips for managing the electrical system of a construction lift. I hope this method will be helpful to you! The electrical system of the lift must be managed by professional electrical staff. Commonly used tools such as multimeters, clamp ammeters, etc. are available.
When an electrical fault occurs, you should first consult the electrical schematic diagram, which reflects the structure and function of the electrical equipment.
.Check whether the voltage of the power supply is normal.
.When the isolating switch and limit switch are turned on, check whether the incoming voltage of the cable in the electrical control box is normal. If the phase failure and phase sequence protector indicator light does not light up, it means that the power phase sequence is connected incorrectly. You can change the phase of the power cord and the indicator light will light up.
. When the elevator is not running, ensure that the thermal relay, safety device micro switch, cage door limit switch, control circuit air switch, etc. are in a closed state. The emergency stop button is not pressed and the main contactor should be closed.
.Check whether the switch signal that controls the up and down movement of the cage can smoothly reach the upper electrical control box and whether the upper and lower stroke limit switch signals can smoothly reach the upper electrical control box and whether it can automatically reset after being moved by hand.
.When the lift is tested for up and down operation, ensure that the motor brake is fully opened.
