7 Operation
D NGER!
Danger of life by crashing the loadt!
Falling loads can ca se serio s inj ry or death.
- Never stand, linger or work below a s spended
load.
- Uns itable s spension points can fail and the load
may drop. The chain hoist load hook sho ld only
be sec red to s itable s spension points on the
load.
- Loads may only be moved nder s pervision.
- Under no circ mstances may a load be s bjected to
a heavy blow or collision.
- A load m st not be lifted by the chain hoist if it is
slipping, falling or if its component parts are not se-
c red firmly together.
- A r sted or damaged chain hoist m st never be
sed.
- A load lifted by the chain hoist sho ld not be left n-
attended.
- Care sho ld be taken d ring lifting that the opera-
tor does not stand within the working range of the
load.
- When leaving the workplace, lower the load.
D NGER!
Overloading is life-threatening!
Carriers not intended for se with the chain hoist and
its load-bearing capacity can give way.
- The chain hoist sho ld always be s spended from
s itable eq ipment which has s fficient load-bear-
ing capacity to withstand the weight of the load and
the chain hoist.
If the load-bearing capacity is exceeded, the chain
hoist may fail and the load may fall.
- Only loads which do not exceed the load-bearing
capacity may be s spended.
C UTION!
Risk of crushing!
Inj ries to hands and fingers may res lt from impro-
per se of the electric chain hoist.
- - Never grasp the chain while the eq ipment is in
operation.
TTENTION!
- Do not carry people on the chain hoist
- Do not transport loads over the heads of personnel
- Do not move loads which exceed the maxim m
load-bearing capacity of the chain hoist (see type
plate).
- The chain hoist m st not be sed for moving jam-
med or wedged loads..
- Loads may not be p lled obliq ely.
- Avoid over- se of jog control (repeated short im-p l-
ses to the motor).
- Do not change the direction of movement s ddenly.
- In order to prevent accidents and to minimise strain
on the chain hoist, never leave a heavy load s s-
pended for a lengthy period of time.
- Do not allow any load to be pressed against the
hook latch. The latch is designed to help hold the
hook in place while the chain is slack before the
sleep chain is picked p.
Use head protection!
Use protective gloves!
Use protective boots!
Wear protective clothes!
NOTE!
- Operating personnel m st be familiar with the oper-
ation and f nctions of the chain hoist and the safety
reg lations pertaining to it.
- The operator is responsible for ens ring that all op-
erating personnel have had the necessary training.

Visual inspection and maintenance
Control of the brake system:
Brake tests are to be carried o t as follows:
Step 1: Attach load
Step 2: Lifting the load
Step 3: Raise and lower load at different heights
Step 4: Test whether it is possible to hold the load in any
position
Checking the load chain for wear
Contin o s monitoring of the load chain is a mandatory
req irement in accordance with DIN 685 Part 5 or UVV
DGUV reg lation 54 (BGV D8 § 27 (VBG 8 § 27).) The
load chain m st be started after commissioning and n-
der normal operating conditions after approx. 10,000
load cycles, to be tested at shorter intervals in severe
conditions.
The links, especially at the points of contact, are to be
checked for wear, cracking, deformation and other da-
mage.
The chain is to be renewed at:
- Red ction of the nominal thickness at the points of
contact by 10% or, if worn to the limit val e in the
table Fig. 5.
- Elongation of a limb by 10% or of the chain over 11
limbs by 4% or, when stretched to the limit val e in
the table Fig. 5.
- rigid-drawn chain links
When changing the chain, check the chain g ide and re-
place if necessary.
