a. To check the oil level, remove the 1/8" pipe plug from the
side of the hoist. With the hoist hanging level, transmission
oil should be even with the edge of the tapped plug hole.
b. The length of time between necessary oil changes will
depend on the severity of use the hoist receives. In general,
the oil should be changed every 12 months of normal
operation, or every 200 hours of actual hoist on-time. Very
heavy use or operation in high ambient temperatures (over
105°F) will require that oil be changed more often. An
indication of the need for oil replacement is load brake noise.
If an erratic tapping sound is made when lowering a load,
the oil should be changed.
The use of gear oils other than that recommended
in Table 5-1 can cause brake chatter or can render
the load brake incapable of holding a load.
A 46 oz. container of this oil is available from
Yale
Lift-Tech. (Part No. 14J1).
WARNING
c. Limit Switch Shaft: To prevent rust, the threaded limit switch
shaft should be given a light coat of grease or sprayed with
a general purpose lubricant.
d. Hook Bearing: Apply a few drops of SAE 30 oil around the
edge of the bearing.
e. Sheave Bearings: At periodic inspections (see Figure 4-1),
and when the wire rope is replaced, wash out the old grease
with solvent and pack with new grease.
f. Trolley Gear Box: At periodic inspections (see Figure 4-1)
check grease level by removing end cap (22, Figure 8-11).
The gear box should be approximately half full of grease. In
general, the trolley gear box lubricant does not require
changing.
g. Trolley Wheel Gears: Apply a light coat of grease to the
pinion and both gears.
Table 5-1. Recommended Lubrication Schedule* Model LEW-1 Electric Wire Rope Hoist
Note: All bearings except hook and sheave bearings are pre-lubricated and sealed.
* This lubrication schedule is based on a hoist operating in normal environmental conditions. Hoists operating in adverse atmospheres
containing excessive heat, corrosive fumes or vapors, abrasive dust, etc., should be lubricated more frequently.
