UNCTION CHECK AFTER INSTALLATION
Prior to operating the hoist, grease the trolley pinions (optional, manual geared and electric trolleys) and lubricate the load chain when it
is not under load (see page 9).
Before the hoist is put into regular service, following additional inspections must be made:
Are all screwed connections on hoist and trolley (optional) tight and are all locking devices in place and secure?
Are the end stops on the trolley runway in place and secure?
Is the chain drive correctly reeved?
Is the chain end stop correctly fitted to the loose end of the load chain?
All units equipped with two or more chain strands should be inspected before initial operation for twisted or kinked chains. The chains of
2-strand hoists may be twisted if the bottom block is rolled over.
Perform an operation cycle without load. The chain should move in a steady, smooth way.
Check the limit switch by moving the bottom block and the chain stop against the housing. The lifting or lowering movement must be
stopped right away.
Check the sliding clutch with a test weight (min. 125% of the rated capacity, max. 5 s).
Check the brake function when lifting and lowering.
Traverse the trolley (if available) the complete length of the trolley runway ensuring that the 2 - 4 mm lateral clearance between the
trolley wheel flange and the beam outer edge is maintained at all times. Check that beam end stops are positioned correctly and secure.
I
NSPECTION BEFORE INITIAL OPERATION
According to the existing national/international accident prevention or safety specifications, lifting units must be checked
• At least once per year by a competent person
• According to the risk assessment of the operating company,
• Before the initial start-up,
• Before restart following a shutdown
• After basic alterations.
Actual operating conditions (e.g. operation in galvanizing facilities) can dictate shorter inspection intervals.
The checks are essentially visual and functional, which should guarantee that the unit is in a safe condition and if necessary, faults and
damages caused by e.g. improper transport or storage, can be identified and remedied.
The condition of components with regard to damage, wear, corrosion or other changes must be assessed, and the completeness and
effectiveness of the safety devices must be determined.
Competent persons may be, for example, the maintenance engineers of the manufacturer or the supplier. However, the company may
also entrust the inspection to its own appropriately trained specialist personnel. The inspections have to be initiated by the operating
company.
Initial operation and recurring inspections must be documented (e.g. in the CMCO works certificate of compliance).
Paint damage should be touched up in order to avoid corrosion. All joints and sliding surfaces should be slightly lubricated. In case of
heavy contamination, the unit must be cleaned.
If the hoist is used as a crane, it has to be inspected and approved by a crane expert before initial operation. This inspection has to be
registered in the crane inspection book. The inspection by the crane expert has to be instigated by the operating company.
O
PERATION
Installation, service, operation
Operators delegated to install, service or independently operate the hoist must have had suitable training and be competent. Operators
are to be specifically nominated by the company and must be familiar with all relevant safety regulations of the country of use.
Inspection before starting work
Before starting work inspect the hoist/trolley, chains and all load bearing components every time for visual defects. Furthermore test the
brake and make sure that the load and hoist/trolley are correctly attached by carrying out a short work cycle of lifting and lowering resp.
travelling in both directions. Selection and calculation of the proper suspension point and beam construction are the responsibility of the
operating company.
Inspection of load chain
Inspect the chain for sufficient lubrication and visually check for external defects, deformations, superficial cracks, wear or signs of
corrosion.
Inspection of chain end stop
The chain end stop must be connected to the free (idle) chain strand.
Inspection of chain reeving
All units with two or more chain strands should be inspected prior to initial operation for twisted or kinked chains. The chains of 2-strand
hoists may be twisted if the bottom block was rolled over.
Inspecting the hooks
Check the load hook and the suspension hook for deformations, cracks, damages, abrasion and signs of corrosion.
