0.4.3 Sound level (SPL)
0.5 Technical status
0.5.1 Technical data
0.5.2 Recurrent checks
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
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

Each device/ unit operator should adequately note all checks, maintenance and
inspections performed in the log book, and have these confirmed by the competent
person in charge.
Incorrect or missing entries will lead to forfeiture of the manufacturer's warranty.
CAUTION !
Equipment and cranes should be periodically tested by an expert. Basically,
visual and functional checks should be performed to determine the
condition of components as regards damage, wear, corrosion or other
modifications. In addition, safety equipment is assessed for completeness
and efficiency. It may be necessary to dismantle the equipment under
inspection to correctly assess expendable parts.
CAUTION !
Suspension apparatus must be inspected over its entire length, including
covered or hidden parts.
CAUTION !
All periodical inspections should be arranged by the operator.
