Control of the brake system
Brake-/Ratche tests areto be carried out as follows:
Step 1: Attach the load
Step 2: Lift the load.
Step 3: Raise and lower load at different heights.
Step 4: Test whether it is possible to hold the load in
every position.
Inspection the load chain for wear
Continuous inspection the chain hoist is a mandatory re-
quirement in accordance with DIN 685 Part 5 or UVV
BGV D8 Section 27 (VBG 8 Section 27). Check the chain
hoist is before commissioning and under normal opera-
ting conditions after approx. 200 operating hours or
10.000 load cycles, in heavy operating conditions in at
shorter intervals
The links should be checked especially at the points of
contact for wear, cracking, deformation and other da-
mage.
The chain must be replaced:
- Reduction of the nominal thickness at the contact
points by 10%
- Elongation of a limb by 3% or the chain over 11
limbs by 2,5% stiff chain links
- stiffened chain links
When changing the chain, check the chain guide and
replace if necessary.

* Nominal values. The concrete value must be measured on the new
hook. The expansion must not be more than 5% of the measure of the
new condition.
ATTENTION!
The brake dsytem must be checked regularly!
ATTENTION!
The brake disc must be replaced if the thickness of
the pane is 2,5 mm (standard thickness 3 mm) or
less or if it is no longer possible to hold the load in
any position.
ATTENTION!
Only use the original replacement chain from the
hoist manufacturer as a replacement chain.
