Passenger elevator lift

When the wear depth of each groove differs by 1/10 of the rope diameter, or the gap between the traction rope and the groove bottom is less than 1mm, the rope wheel should be removed for repair or replacement. (5) Check the length of traction rope, speed limit rope and balance rope. The elevator stops at the leveling position of the upper station, from the bottom of the counterweight to the upper end of the hydraulic buffer 150mm, to the upper end of the spring buffer 200~350mm, and the rope should be cut if the size is below the lower limit.

After the length of the traction rope meets the requirements, measure the length of the balance rope. The tension wheel frame of the balance rope device should be 200mm from the ground channel steel. If it is lower than this value, the rope should be cut. The balance chain generally does not extend.

If it does extend, check whether the joints of each chain link and the fixing bolts at both ends are tight. Check whether the distance between the bottom of the speed-limiting rope tensioning device and the pit ground meets the requirements and whether the iron arm is balanced. The distance requirements: domestic ladder, high-speed ladder 750\; fast ladder 550\;50mm; low-speed ladder 400\;50mm; Japanese ladder, 200\50mm. The rope should be cut below the above lower limit. 2.3.5 Guide rails and brackets (1)

Check whether the Passenger elevator lift of the car and counterweight guide rail brackets are loose, whether they are unwelded and whether the civil engineering connections are loose. (2) Clean the working surface of each guide rail and add oil appropriately. Check whether the rail connecting plate bolts are loose and whether the rail is deformed. 2.3.6 Follow the line (1) Check whether there are any objects in the hoistway that are in contact with the cable, whether the cable sheath is cracked during operation, and whether the cable is twisted.
