6. INSPECTION AND MAINTENANCE
NOTE : A maintenance program should start for each hoist immediately after it is entered into service. This
maintenance program should comply with recommendations in the applicable parts and Instruction
Manual, and all pertinent Federal, State, Provincial and Local regulations. Regular inspections should
be followed for the life of the hoist and documented by written inspection records.
Use only TRACTEL replacement parts. The replacement of any part with anything other than a TRACTEL authorized replacement part
may adversely affect the function and safety of this hoist and voids the warranty. TRACTEL disclaims liability for any claims of dama-
ges, whether warranty, property damage, personal injury or death arising from the use of unauthorized parts.
6.1 - Load Chain Inspection
Tralift TE hoist is supplied with a special case hardened load chain, grade 80 or better suited to use on electric chain hoists.
WARNING
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. The chain should be measured and
must be replaced if the measurements are greater than those given in the following table.
1) Place the hoist in it’s operating position with the load chain hanging down.
2) Count 11 links (Fig. 19) and mark them.
3) Clean the links with a non-caustic solvent which is neither acidic or caustic (a white spirit type solvent is recommended but
only if it is according to National / Provincial / local environmental regulation ).
4) Measure the 11 links and compare the measurements to Fig. 19.
5) Examine the load chain. The load 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 (212° F) or to abuse from mechanical or chemical agents. If so, the load
chain must be replaced. Lightly oil the load chain regularly with SAE 120 type oil or equivalent.
CAUTION
Lubricants must be handled and disposed of according to local, state and federal regulations.
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.
ADVANCED LOAD CHAIN INSPECTION
1) Obtain a single link from the load chain to be inspected.
2) Take measurements of p, d4, and d5 (Fig. 22).
3) Calculate dm and d5.
4) Compare the calculations to Fig. 22
WARNING
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. The chain should be measured and
must be replaced if the measurements are greater than those given in the following table.
6.2 - Load Chain Replacement
WARNING
Using other than TRACTEL supplied load chain may cause chain to jam in hoist or chain breakage. For proper size and phy-
sical properties use only TRACTEL supplied chain. TRACTEL declines all responsibility for hoists used with chain supplied
by others.
WARNING
When the load chain needs to be replaced, this operation must be performed by a TRACTEL approved repair shop or quali-
fied technician.
