7.3 Operation
7.3.1 General
DANGER
Broken chains and load drop
Frequent approaches of the emergency limit stop device may result in broken chains or load drops.
For chain hoists without operating limit switch or with defective operating limit switch, the slipping clutch of the chain
hoist perfoms the function of the emergency limit stop device. This emergency limit stop device may only be ap‐
proached in exceptional cases, i.e. it must not be approached in normal operation. When the slipping clutch is
tripped, high additional loads are exerted on the chain.
Therefore the function "Operating limit switch for lifting" must be checked every day..
WARNING
Overload
Danger to life and limb.
Higher loads than those specified on the load capacity plate must not be handled.
– Please note the maximum permissible load capacities of the hoist.
– Use load handling attachments which are sufficiently dimensioned.
– Use the load handling attachments as intended.
Important information on operation
Please follow the instructions below during operation:
Safety during operation
– Take the machine out of service immediately if functional defects or irregularities are detected.
– The operator is obliged to check the machine for visible damage at least once per shift and to report damage
immediately.
– Do not render safety devices inoperative.
– Limits must not be approached in normal operation, e.g. emergency stop devices (emergency limit switches),
emergency limit stop devices (slipping clutch or emergency limit switch), track and end buffers for stopping
motion of the trolley or crane, hook assemblies or bottom block against end stops. Continuous approaches of
these limits may result in severe damage on the chain hoist up to chain breakage.
