J. D. NEUHAUS JDN mini Series, Operation And Assembly Instructions

Page: 22 / 48

A copy of the special publication ˝Recommended lubri-
cants˝ is available on request.
Hoists, including the supporting structure, must be
inspected by an appropriately trained and qualified
person before initial operation and before re-commis-
sioning after significant modifications. Hoists and
lifting gear which are installed in trolleys must be
inspected by a specialist.
The inspection covers the proper mounting, equipment
level and operational-readiness, in the main, the com-
pleteness, suitability and effectiveness of the safety
devices as well as the condition of the device, the
harness, the equipment and the supporting structure.
Safety devices are braking devices, overload protection
devices, EMERGENCY STOP devices, lifting and lowering
limiters (emergency end-stop devices).
A description of the inspection can be found in the
Maintenance section, page 29.
