1.3. Special safety directions
Transport and assembly:
– Electric chain hoists, single parts and large components should
EN
be carefully affixed to suitable and technically acceptable hoisting
apparatus / load lifting members.
Connection:
– Connection work is only to be performed by personnel specifically
designated and trained for the job.
Start-up / operation:
– Before initial start-up, as well as daily start-up, carry out a visual check
and carry out the predefined user-checks routine.
– Only operate the electric chain hoist if the protective and safety
equipment provided is ready and working.
– Damage to the electric chain hoist and changes in its operational
characteristics must be reported immediately to the person responsible.
– After use, or when in a non-operational mode, the chain hoist should be
secured against unauthorised and unintentional use.
– Refrain from hazardous procedures.
See also operational parameters (chapter 1.6).
Cleaning / service / repair / maintenance / refitting:
– Use the working platforms and ladders provided for assembly work
above body height.
– Do not use machine parts for this purpose.
– Check electrical cables for damage or wear.
– Ensure any oils or other agents used are discharged, collected and
disposed of safely and in an environmentally sound manner.
– Reassemble and check safety apparatus that has been disassembled
for servicing or repairing the hoist once service and repair work has
been completed.
– Adhere to predefined testing and service intervals specified in the
instruction manual.
– Operating personnel should be informed before commencing special
or refitting work.
– Secure the repair working area.
– Prevent the electric chain hoist from being inadvertently switched on
during service.
– Erect warning signs.
– Disconnect the power cable and ensure it cannot be inadvertently
switched on again.
– Retighten screw connections that have been loosened or service work.
Shut down / storage:
– Clean and preserve (lubricate/grease) the chain hoist before long
periods of inactivity or storage.
1.4. Notes on hazard protection
Hazardous areas must be clearly marked by warning signs and cordoned
off. It must be ensured that warnings regarding hazardous areas are
given due attention.
Hazards can appear from:
– incorrect application;
– not following safety directions properly;
– not carrying out test and service work thoroughly.

1.4.1. Hazards caused by mechanical influences
Physical injury:
DANGER!
Unconsciousness and injury through:
– crushing, shearing, cutting and twisting;
– drawing in, ramming, piercing and rubbing;
– slipping, stumbling and falling.
Causes:
– crush, shear and twist area;
– parts rupturing or bursting.
Safety options:
– keep floor, equipment and machinery clean;
– eliminate leakages;
– observe the required safety distance.
1.4.2. Hazards caused by electrical energy / power supply
Work on electrical apparatus or machinery may only be performed by
qualified electricians or persons under the supervision and guidance
of qualified electricians, in accordance with predefined electrotechnical
regulations.
Physical injury:
DANGER!
Death from electrical shock, injury and burns through:
– contact;
– faulty insulation;
– faulty servicing or repair work;
– short circuit.
Causes:
– contact with, touching or standing too close to uninsulated power and
voltage supply terminals;
– use of uninsulated tools;
– exposed electricity supply terminals following insulation failure;
– inadequate safety checks following repair work;
– incorrect fusing.
Safety options:
– isolate machinery and equipment designated for repair or service work
before commencing such work;
– first check isolated parts for voltage;
– regularly check electrical fittings;
– replace loose or damaged cables immediately;
– always replace blown fuses with fuses of the correct value avoid
contact with or touching live terminals only use insulated tools.
1.4.3. Sound level (SPL)
Tests on the chain hoist sound level are performed at a range of 1, 2, 4, 8
and 16 metres from the centre of the chain hoist motor to the measuring
device.
Measurement of SPL according to DIN 45 635.
The SPL was measured:
a) during operation of electric chain hoists on factory site.
b) during open-air operation.
