6.0 Maintenance and Handling
6.1 Lubrication
6.1.1 Load Chain
For longer life, the load chain should be lu bricated.
The load chain lubrication should be accompli shed after cleani ng the load chai n with an acid free
cleaning solution.
Apply Harrington lubricating grease (Part No. ER1BS1951) or an equivalent to ind ustrial general lit hium
grease, NLGI No. 0, to the bearing surfaces of the load chain links as indicat ed by the shade d areas in
Figure 6-1. Also apply the grease to the areas of the load chai n (shaded areas in Figure 6-1) that
contact the load sheave. Insure that the grease is applied to the contact areas in the load sheave
pockets.
Machine or gear oil (grade ISO VG 46 or 68 oi l or equivalent) m ay be used as an alternative lubric ant
but must be applied more frequently.
Figure 6-1 Chain Grease Application
The chain should be lubricated every 3 month s (more frequently for he avier usage or seve re
conditions).
For dusty environments, it is acceptable to substitute a dr y lubricant.
6.1.2 Hooks and Suspension Components:
Hooks – Bearings should be cleaned an d lubricated at l east once per year for norm al usage. Clean
and lubricate more frequently for heavier usage or severe conditions.
Suspension Pins - Lubricate the chain pin a nd the top pin at least t wice per year for n ormal usage;
more frequently for heavier usage or severe condition s.
6.1.3 Applying Grease to Sheaves and Idle Wheels:
Remove old grease and replace the new grease (NLGI No. 2), at annual inspe ction.
Temperature range of standard grease is -20˚C ( -4˚F) to + 60˚C (140˚F). If the hoist is used at
temperatures below -20˚C (-4˚F) or above 60˚C (140˚F), consult the manufacturer or dea ler since some
parts should be changed.

6.2.1
WARNING
ALWAYS store the hoist in a no load condition.
ALWAYS wipe off all dirt and water.
ALWAYS oil the chain, hook pins and hook l atches.
ALWAYS hang in a clean and dry place.
ALWAYS check the hoist for abnormalities (acco rding to the regular inspection procedures) when
using the hoist after a period of non-u se (Refer to Section 5.7).
6.3 Outdoor Installation
6.3.1 For trolley hoist installations that are outdoors, th e trolley hoist MUST B E covered and prote cted from
the weather at all times.
6.3.2 Possibility of corrosion on components of the trolley hoist increases for installations where salt air and
high humidity are present. The trolley hoist may require more frequent lubrication. Make freque nt and
regular inspections of the unit's co ndition and ope ration.
6.3.3 For trolley hoist installations where temperatur e variations intro duce condensation i nto the hoist
additional inspection and more frequent lub rication may be requ ired.
6.3.4 Refer to Section 2.1.2 for allowable environmental conditions.
: IMPROPER chain hoist storage could result in death or serious i njury. To avoid
these hazards:
