DEMAG DC-Com 5 User Manual

Fitting the limit stop
Fig. 55
● Fix limit stop to the 5th link at the dead (unloaded) end of the chain
paying attention to the tightening torque.
● If the chain hoist is operated with a chain that is longer than suitable
for the standard capacity of the chain collector box, an additional limit
stop must be fitted to the chain between the hook assembly and the
buffer plate. The limit stop must fitted so that the excess length of the
chain lies between the hook assembly and the limit stop. In this case
a geared limit switch is required for the DC-Com 10 with 2/1 reeving.
After having replaced the chain set:
● Fit the hook assembly/bottom block ⇒ "Load hook", Page 88
● Lubricate the chain ⇒ "Available hoist chains", Page 83, ⇒ "Lubricating the hoist chain", Page 87
● Adjust the lower hook position as required ⇒ "Setting the lower hook position", Page 58.
● If an optional geared limit switch is fitted to the chain hoist, it must be readjusted after having replaced the chain,
see brochure DC geared limit switch ⇒ Tab. 3, Page 7.

8.5.5.8 Lubricating the hoist chain
Fig. 56
After fitting, before lifting a test load and putting the hoist
into operation as well as during normal operation, the chain
link contact areas must be lubricated with a gear grease,
part no. 665 009 44, along the entire length of the chain,
which must be free of load.
The chain link contact areas must be relubricated appropriately – after
being cleaned – at intervals depending on the service and load conditions.
A dry film lubricant should be used in environments where abrasives occur
(emery, sand, etc.). Deviating lubrication see ⇒ "Available hoist chains",
Page 83!
Cut off the tip of the grease tube and insert the grease tube at the lubri‐
cation point. To ensure complete and even lubrication of the chain, move
the chain into its end positions while you fill the grease into the chain guide
by pressing on the tube.
