AFTER AN INTENSIVE PERIOD OF USE, THE CHAIN
MAY SHOW SIGNS OF ELONGATION OR WEAR
WHICH COULD DAMAGE THE HOIST OR CAUSE THE
CHAIN TO BREAK. IT IS THEREFORE
RECOMMENDED THAT THE LIFTING CHAIN IS
INSPECTED REGULARLY (Refer to Table 2). THE
CHAIN SHOULD BE MEASURED AND MUST BE
REPLACED IF THE MEASUREMENTS ARE GREATER
THAN THOSE GIVEN IN THE FOLLOWING TABLE.
In this case, it is also recommended that the
wear of the chain guide and the load sprocket
wheel is checked at an approved service shop.
For taking measurements the chain must be
cleaned with a solvent which is neither acid nor
caustic (use a white spirit type solvent).
In addition, when each link on a total length of
11 links Figure 6 has been examined, the chain
must be replaced if any of the following
is found:
• Corroded or cracked links.
• Distorted or twisted links.
• Stretched or particularly worn links.
Do not expose the chain to temperatures
greater than 100° C or to attack from
mechanical or chemical agents.
Lightly oil the load chain regularly with SAE 120
type oil or equivalent.

NOTE
: Systematically or repeatedly stopping
and starting at the same place will cause more
rapid wear of the links which stop on the load
sprocket wheel. If the chain needs to be
replaced, this must be performed by a
TRACTEL
approved service shop.
