6.0 Lubrication
6.1
Air Hoist Lubrication
6.1.1
See
Section 3.0
for lubrication requirements.
6.1.2
Lubrication to the motor will be provided primarily by the air supply lubricator. The
recommended amount is 10-15 drops/minute (0.2-0.3 cc/min). Refer to
Table 6-1
below for the
approved lubricant for use with your air hoist.
6.1.3
Additional lubrication to the reduction gears is not necessary. When disassembling the hoist for service
or repair, apply new grease to the gears before reassembling the hoist.
6.2
Load Chain Lubrication
6.2.1
For longer life, the load chain should be lubricated.
6.2.2
The load chain lubrication should be accomplished after cleaning the load chain with an acid free
cleaning solution.
6.2.3
Apply Harrington lubricating grease (Part No. ER1BS1951) or an equivalent to industrial general lithium
grease, NLGI No. 0, to the bearing surfaces of the load chain links as indicated by the shaded areas in
Figure 6-2
. Also apply the grease to the areas of the load chain (shaded areas in
Figure 6-2
) that
contact the load sheave. Insure that the grease is applied to the contact areas in the load sheave
pockets.
6.2.4
Machine or gear oil (grade ISO VG 46 or 68 oil or equivalent) may be used as an alternative lubricant
but must be applied more frequently.
Figure 6-2
Chain Grease Application
6.2.5
The chain should be lubricated every 3 months (more frequently for heavier usage or severe
conditions).
6.2.6
For dusty environments, it is acceptable to substitute a dry lubricant.
