Weekly Maintenance (every 40-Hours)
•
IF LIFT IS ANCHORED TO FLOOR
- Check anchor bolts torque to
50 ft-lbs
for the ¾
in. anchor bolts. Do not use an impact wrench to tighten anchor bolts.
•
Check floor for stress cracks near columns
•
Check hydraulic oil level.
•
Check and tighten bolts, nuts, and screws.
•
Check all cable sheaves/assembly for free movement or excessive wear on cable
sheave shaft.
Yearly Maintenance
•
Lubricate the cable sheave shaft by using grease gun at lease once a year after the
lift is in service.
•
Check for excessive wear of cable. Replace them if necessary.
•
Change the hydraulic fluid - good maintenance procedure makes it mandatory to keep
hydraulic fluid clean. No hard fast rules can be established; - operating temperature,
type of service, contamination levels, filtration, and chemical composition of fluid
should be considered. If operating in dusty environment shorter interval may be
required.
Special Maintenance Tasks
NOTE: The following items should only be performed by a trained maintenance expert:
•
Replacement of hydraulic hoses.
•
Replacement of cables and sheaves.
•
Replacement or rebuilding air and hydraulic cylinders as required.
•
Replacement or rebuilding pumps / motors as required.
•
Checking of hydraulic cylinder rod and rod end (threads) for deformation or
damage.
CAUTION!!
Relocating or changing components may cause problems. Each component in the
system must be compatible; an undersized or restricted line will cause a drop in
pressure. All valve, pump, and hose connections should be sealed and/or capped until
just prior to use. Air hoses can be used to clean fittings and other components.
However, the air supply must be filtered and dry to prevent contamination. Most
important is cleanliness; Contamination is the most frequent cause of malfunction or
failure of hydraulic equipment.
