The end user of the crane is responsible for the proper
qualifications of the commissioning personnel.
Persons can be injured if the crane
is incorrectly put into operation.
If personnel other than that of the
ABUS company are employed to
perform the crane commissioning, it
is the end user’s responsibility to
ensure that these persons are
adequately qualified. Follow the
procedures described here
precisely.
Examples of qualified persons:
─ Persons with comprehensive knowledge from
specialist training in engineering and in the
electrical systems of cranes.
─ Persons with sufficient experience in the
operation, installation and maintenance of
cranes.
─ Persons with comprehensive knowledge
regarding the relevant technical rules,
directives and safety regulations applicable in
the respective country.
─ Persons receiving regular training from ABUS.
ABUS assumes no liability for damage due to
incorrectly performed commissioning work done by
unqualified personnel.
ABUS recommends having the commissioning work
performed by the ABUS assembly team.
CHECKING THE REQUIREMENTS
The following requirements must be met in order for
the chain hoist to be mounted.
CHECKING THE LOAD CAPACITY
─ The supporting structure (steelwork, building,
crane installation) from which the chain hoist is
to be suspended must have a sufficient load
capacity.
The load capacity of the supporting structure is
derived from the weight of the chain hoist, the
maximum load capacity of the chain hoist, the weight
of the trolley (if applicable) and possibly the additional
weight of the chain as well.
For the weight of the chain hoist, refer to the
table.
If the hook path of the chain hoist is longer than
3 metres: Add the additional weight of the
chain.

GM2 Single-fall 22 kg 0.34 kg
GM2 Twin-fall 25 kg 0.68 kg
GM4 Single-fall 30 kg 0.65 kg
GM4 Twin-fall 34 kg 1.30 kg
GM6 Single-fall 57 kg 1.24 kg
GM6 Twin-fall 63 kg 2.48 kg
GM8 Single-fall 94 kg 2.27 kg
GM8 Twin-fall 108 kg 4.54 kg
Table: Weight of the chain hoists. The
specifications are based on a hook path of 3
metres.
Add the maximum load capacity.
Only for trolley: Add the weight of the trolley.
Check the entire supporting structure as to
whether it will support the expected load.
