6. SERVICE
Service and inspections may only be carried out by a compe-
tent person.
The inspection must determine that all safety devices are
present and fully operational and cover the condition of the
hoist, lifting gear, accessories and supporting constructions.
The service intervals inspections noted are for normal work-
ing conditions. Adverse working conditions e.g., heat or chemi-
cal environments can dictate shorter periods.
Yale pneumatic hoists conform to the machinery group 1AM
resp. 1Bm in accordance with FEM 9.511. This results in a
theoretical service-lifetime of 800 resp. 400 operating hours
under full load. This is equivalent to 10 years under normal
operating conditions. After this period the hoist requires a gen-
eral overhaul. Further information is contained in VBG 9 resp.
FEM 9.755.
6.1 DAILY CHECKS
1.) Visually check the pendant control unit and air hoses for
damage.
2.) Check that the brake functions correctly.
3.) Check that the overload safety device functions correctly.
4.) Chain hoists with trolley:
– Check that the trolley runway is free from obstructions.
– Check that the end stops on the trolley runway are fitted
and secured.
6.2 REGULAR INSPECTIONS, SERVICE, TESTING
According to national and international safety regulations hoist-
ing equipment must be inspected annually by a competent
person. Adverse working conditions e.g., heat or chemical
environments can dictate shorter periods.
The commissioning and inspection details can be noted in the
enclosed inspection sheet.
Repairs may only be carried out by specialist workshops that
use original Yale spare parts.
Attention:
Disconnect the air supply before performing test
unless air is required for a particular test.
