LOAD CHAIN
Cleaning and Inspection
First clean load chain with a non-acid or non-caustic type
solvent. Then slack the chain and make a link-by-link
inspection for nicks, gouges, twisted links and excessive
wear or stretching. Chain exhibiting wear should be
checked throughout its entire length and replaced if
worn beyond serviceable limits.
Checking For Load Chain Wear
Slack the portion of the chain that normally passes over
the liftwheel. Examine the interlink area for the point of
maximum wear (polishing). Measure and record the stock
diameter at this point of the link. Then measure stock
diameter in the same area on a link that does not pass
over the liftwheel (use the link adjacent to the loose end
link for this purpose). Compare these two measurements.
If the stock diameter of the worn link is 0.010 inches
(0.254mm), or greater, less than the stock diameter of
the unworn link, the chain must be replaced.
Note that worn chain can be an indication of worn hoist
components. For this reason, the hoist’s chain guides,
hook blocks and liftwheel should be examined for wear
and replaced as necessary when replacing worn chain.
Also, these chains are specially heat treated and hard-
ened and should never be repaired.
WARNING
Using other than factory supplied load chain may
cause the chain to jam in the hoist and/or allow the
chain to break and the load to drop.
TO AVOID INJURY:
Due to size requirements and physical properties, use
only Hoistaloy
®
load chain in the XL Hoists.
!
IMPORTANT:
DO NOT USE REPLACED CHAIN FOR OTHER PURPOS-
ES SUCH AS LIFTING OR PULLING. LOAD CHAIN MAY
BREAK SUDDENLY WITHOUT VISUAL DEFORMATION.
FOR THIS REASON, CUT REPLACED CHAIN INTO
SHORT LENGTHS TO PREVENT USE AFTER DISPOSAL.
PROTECTOR™
The Protector should operate for the normal life of hoist
without service. The device has been calibrated at the
factory for a specific capacity/gear ratio of XL Hoist. It is
not adjustable and it is not interchangeable with other
capacities/gear ratios.
