Repair and Maintenance
Keep clean
z This unit should be cleaned with dry cloth frequently
to keep it clean. Before cleaning, first switch off the
power to ensure the safety.
z The working environment of this unit should be clean.
In case of dust in the working environment, it will
speed up the parts wearing and shorten the service
life of the lift.
Every day:
z Before the operation, carefully check the safety
mechanism of the lift to ensure the electromagnet
suction and release action is proper, and the safety
plate is in good condition. When finding any abnormal
situation, make adjustment, repair or replacement
immediately.
z Check to see if the steel cable connection is proper,
and if the tension is at the optimum status.
z Check to see if the connection between hydraulic
cylinder and carriage is proper, if the connecting nut
between the steel chain and carriage is loose or
falling. Refer to Fig.6
Fig.6
Every month:
z Retighten the anchor bolts.
z Lubricate chains/cables.
z Check all the chain connectors, Bolt s and pins to
ensure correct installation
z Check all the hydraulic lines for wearing
z Check to see if the carriage and the inner side of the
column are properly lubricated. Use high-quality
heavy lubrication grease (lithium based lubrication
grease GB7324-87).
Note: All the anchor Bolt s should be tightened
completely. If any screw doesn’t function for some
reason, the lift can not be used until the bolt is
replaced
Every six months:
z Check all the movable parts for possible wearing,
interference or damage.
z Check the lubrication of all the pulleys. If the pulley
has dragging during the lifting and lowering, add
appropriate lubricant to the wheel axle.
z When necessary, check and adjust the balancing
tension to ensure the horizontal lifting and lowering.
z Check the verticality of the column.
Note: The inner corner of each column should
be lubricated with lubricant, to minimize the roller
friction and ensure the smooth and even lifting.
Maintenance of hydraulic system:
z Clean and oil change
In the six months after initial use of this unit, clean the
hydraulic oil tank and replace the oil, later clean the
hydraulic system once a year, and replace the oil.
See Fig. 7
z Replace the seal
After this unit is put into operation for certain period, if
finding the oil leakage, carefully check it; if the
leakage is due to the wearing of sealing materials,
immediately replace the worn one based on the
original spec. See Fig. 7
