Fitting the chain anchorage for 2/1 reeving on DC 10
Fig. 52
● Fit the chain anchorage before bolting the guide plates into position for DC 10 hoists with 2/1 reeving. Bolt
chain anchorage halves (1) together (fig. A).
● Insert the bolted chain anchorage into the opening of the gearbox housing (fig. B).
● Fit pins (2) (the pins are retained by the fitted guide plates).
Fitting the limit stop
Fig. 53
● Attach the limit stop to the 5th link at the dead (unloaded) end of the
chain; pay attention to the tightening torque.
● If the chain hoist is operated with a replacement chain that is longer
than suitable for the standard capacity of the chain collector, an addi‐
tional limit stop must be fitted to the chain between the hook assem‐
bly and the buffer plate. The limit stop must be fitted in such a way
that the extra length of chain is positioned between the hook assem‐
bly and the limit stop. In this case, a geared limit switch is required
for DC 10 units with 2/1 reeving.
Furher procedure after replacing the chain set
If the chain has to be replaced because it has reached its wear limit, the return sprockets are usually also worn
and have to be replaced. For this reason, the condition of the return sprockets must be checked when the chain
is replaced. We recommend that the return sprocket should be replaced no later than every second time the
chain is replaced.
