Maintenance guide

What matters should be paid attention to in daily maintenance of elevator?

Correct maintenance and maintenance can prolong the service life of the elevator and reduce the failure rate of the elevator. Elevator maintenance can be roughly divided into: daily maintenance, monthly maintenance and annual maintenance.

Daily maintenance:

(1) Check the wire rope and guide wheel of counterweight door for wear

(2) Check the oil pipe, joint and oil cylinder for oil leakage

(3) Check all travel switches for looseness

(4) Click the elevator to check whether there is abnormal noise

Monthly maintenance:

(1) Check whether the roller, bearing and other stressed parts are worn, and whether the fastener parts are loose

(2) Check all travel switches for good contact

(3) Whether the oil cylinder leaks oil and whether the electroplated coating peels off

(4) Whether the overload protection device operates normally

(5) Whether the circuit connection is clean, whether the connection is firm and whether it works normally

Annual maintenance:

(1) When the lift rises to a higher level, is the oil level 40-50mm higher than the oil suction port

(2) Whether the hydraulic oil deteriorates, if so, replace the hydraulic oil in time

(3) Cleaning oil system

(4) Check other parts for abnormal phenomena
