Inspection; Periodic Checks; Checking The Load Chain - HADEF 240/12 Installation, Operating And Maintenance Instruction

Procedure:
 Only insert new chains in an unloaded state and as the chains that are currently in the device – i.e. not
twisted.
 Remove chain from its fastening at the end and attach a chain link which is open at the side.
 A chain link which is open at the side, can
easily be produced by grinding out a small
piece. The opening must have the same
thickness as the chain link.
 Hang a new original chain (same size and oiled) in the side opened chain link and insert it.
 Make sure the chain is not installed twisted.
 Make sure the chain links are aligned in one direction.
 Assemble the chain to the end fastening.

Inspection

12.1

Periodic checks

Independently from the regulations of the individual countries, lifting devices must be checked at least yearly
by a qualified person or licensed qualified person regarding its functional safety.
12.1.1 Components to be checked
The following must be checked:
 Dimensions of load chain, load hooks, pawls, bolts, ratchet wheels, brake linings.
The dimensions must be compared to the dimensions in the tables.
 A visual inspection for deformations, cracks and corrosion must be carried out.
CAUTION!
When the wear limit is reached, the part must be exchanged by a new, original part.
Check screw connections
Check lifting, lowering functions.
Check brake function
Check free-wheeling of chain
(only applicable for ratchet lever hoists with free-wheeling
mechanism)
Brake - check the brake disc thickness
Check sprocket wheels, ratchet wheels, pawls, bolts
Clean and lubricate the load chain
Check the load chain for elongation and wear
Check the load hook for cracks and deformation
Load hook - check the safety latch
Check and lubricate the bearing of the chain pulleys
Check the chain pulleys
Check the rubber end stops
Check the trolley wheels for wear
Check lubrication of the trolley driving pinion
Have the equipment checked by a qualified person
(periodic inspection)
WARNING!
If one or several of the dimensions fall below or exceed the dimensions in the table, or if cracks or
corrosion are found, the parts must be replaced with original spare parts.
12.2

Checking the load chain

CAUTION!
The load chain must be tested over its entire length!
The measure of the load chain must be carried out especially in the areas which are subject to the highest
wear. Through the lifting movement, these are the contact points of the chain with sprocket wheel and
deflection pulleys.
