Security and stability of the advantages of a relief valve: prevents upward movement when the system pressure is too high 2, emergency manual valve: When the power fails, can the car down to the nearest emergency position-floor door, 3, hand pump: When When the system fails, manually steerable high-pressure oil pump shot the car up to the nearest floor location; 5, the oil tank protection: When the oil temperature in the tank exceeds the standard set value, the oil protection device generating signal, pause Elevator use, when the oil temperature drop before starting the lift. ④ install the right cage, the cage on the guide rollers release the motor brake is released with a lifting device to the mounting position cage hanging rail lifting platform, so that the drive plate rack and pinion on standard section engaging the guide roller clinging standard chord section of the main rail lifting platform pictures, slowly cage down. Rail in place after lifting platform lifts, update installed guide rollers, guide rollers and adjust main chord gap is 0.4mm ~ 0.6mm eccentric shaft through the guide rollers, and then adjust the drive plate on the back of two back wheels, making it contact with the rack on the back. Rack and pinion backlash 0.2mm ~ 0.5mm, the contact spots along the tooth along the tooth length should be ≥40% ≥50%.
