Inspection

11.1

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.
11.1.1 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
for ratchet lever hoists: Check free-wheeling mechanism of the
chain
Brake - check wear of brake lining
Check chain wheels, ratchet wheels and pawls.
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 catch
Check and lubricate the bearing of the chain pulleys.
Check the chain pulleys
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.
11.2

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.
acc. DIN 685-part 5
L11 = pitch increase over 11 chain links
L1 = pitch increase over 1 chain link
dm= detected link diameter (d1+d2)/2
