USE AND MAINTENANCE MANUALUSE AND MAINTENANCE MANUAL
Chain hoist from 198kg to 2500kg
The chain must not be crushed, cracked, permanently deformed or damaged by corrosion and/or chemical
agents, otherwise it must be replaced. The chain may be replaced only by authorised EXE TECHNOLOGY
personnel.
On a quarterly basis, inspect the chain at the points of contact between the links to check that wear is regular
and within tolerance limits as defined below:
10% maximum shrinkage of the link's mean diameter
dm due to friction, calculated in the two
positions rotated by 90° according to the formula:
dm=(d1+d2):2 ≤ 0.9d
5% increase in the single link pitch 1t (inner length
measured on the major axis) calculated by
comparing with a chain link located after the chain stop
2% increase in the length of 11 links 11t, calculated by
comparing the 11 chain links located after the chain stop
If the chain is not sufficiently lubricated and/or noisy or tends to jam, clean with neutral solvent and
lubrication with lubricant for high pressure applications.
The chain should be able to slide smoothly into and out of the chain guide of the hoist, or hook block in the
case of the double chain hoist.

7.2.3 CHAIN LOAD LUBRIFICATIONCHAIN LOAD LUBRIFICATION
Before lubricating the chain, secure the hoist. To ensure long service life and best performance, lubricate the
chain with the following lubricant or a compatible one:
STABYLAN 2001: a green semi-synthetic, medium viscosity lubricant, used for lubrication of all types of chains,
even at higher temperatures (-15 / + 150 °C).
The consistent application of even small amounts of lubricant greatly increases the lifespan of the load chain.
DANGERDANGER
Do not allow the chain to dry.Do not allow the chain to dry.
It is essential to keep the chain clean and lubricate it regularly with chain oil. Normally, weekly lubrication and
cleaning of the chain is sufficient, but in hot and dirty conditions, it may be
necessary to clean the chain at least once a day and lubricate it several times between cleaning operations.
When lubricating the chain, apply sufficient lubricant to achieve normal movement and full coverage, especially at
the points of contact between links.
CAUTIONCAUTION
Do not use used motor oil as a chain lubricant.Do not use used motor oil as a chain lubricant.
