Elevator installation quality verification common problems in elevator installation stage elevator manufacturers, integrated debugging, and comprehensive on-site inspection of the elevator installation quality is extremely important to ensure a safe working elevator can run. After each elevator installation is complete, it should be 59 required by the GB 10060-93 "elevator installation acceptance" under one check. Now a few questions elevator installation quality verification often encountered, we hope to attract everyone's attention. Elevator installation quality verification of Frequently Asked Questions 1, the limit switch is installed to protect the position of the counterweight with the process and test but because of the constant traction rope elongation sightseeing elevator price, S2 continues to decrease. When S2 is reduced to a certain extent, with the limit switch mounting position relative not reasonable, then the inevitable can not meet the requirements of Article 4.6.5 of the case. Cause because of the weight has been pressed buffers (refer to an accumulator buffer), and balance the weight of the car, the car does not rise elevators, and the motor still running, causing the hoisting rope in the sheave grooves skid, damage to the equipment. Otherwise, it must increase the workload of routine maintenance, repeat the adjustment of the hoisting ropes to avoid equipment damage. To this end, we recommend: the installation stage, the counterweight is 2 to 3 basis adjustment of the elevator quote pad installation, the value of S2 should try to take maximum. The upper limit switch mounting position for energy-consuming buffer, preferably not more than 150mm, for energy storage buffer should not be greater than 200mm.
