Precautions and safe operations before starting the 2016 Beijing construction elevator

Construction lifts
Construction lifts for people and goods are now essential in the construction industry. Today I will take you through the precautions and safe operations before starting the construction lift. I hope it can help you! 1. Before starting the elevator, check and confirm that the cables and grounding wires are intact and the control switch is in the zero position. After the power is turned on, check and confirm that the voltage is normal and test that there is no leakage. It should be tested and confirmed that the electrical interlocking devices at each limit device, ladder cage, enclosure door, etc. are good and reliable, and the electrical instruments are sensitive and effective. After starting, a no-load lifting test should be carried out to measure the effectiveness of the brakes of each transmission mechanism. Only after confirming that it is normal, can the operation begin.
2. When an abnormality is discovered during the operation of the construction elevator, it should be stopped immediately and effective measures should be taken to lower the ladder cage to the bottom floor. The operation can only continue after the fault is eliminated. When electrical out-of-control is discovered during operation, the emergency stop button should be pressed immediately. Do not open the emergency stop button until the fault is eliminated.
3. When the construction lift reaches the uppermost or lowermost level, it is strictly forbidden to use the travel limit switch as a control switch to stop operation.
4. When the construction elevator stops midway due to power outage or other reasons, it can be lowered manually, and the manual release handle of the brake electromagnet at the end of the motor is slowly pulled out to slow down the ladder cage. Slide down. When the ladder cage slides down, the rated operating speed must not be exceeded, and manual descent must be operated by professional maintenance personnel.
