Servicing
Perform any servicing work after using and before storing the equipment. Servicing and repairs may only be executed by trained
professional staff.
(a) Clean the chain block thoroughly.
(b) Lubricate the chain block properly at all times. Lubricate the load hook chain and joint with oil.
(c) Protect the chain block against rain and moisture when storing the equipment.
Special attention must be paid to servicing when installing the chain block outdoors.
Chain and hook
The load hook and chain are made out of alloy steel and treated
thermally. Correction welding and thermal treatment on the load hook
and chain is strictly prohibited. This would result in changed material
properties.
(a) The chain life is sufficiently dimensioned. Nevertheless,
the life is shortened due to external influences.
If a length of 21 chain links given in table 1 is exceeded,
the chain must necessarily be replaced.
(b) The load hook gets deformed when handled unprofessionally
or when overloaded. The load hook must immediately be replaced
if the g dimension reaches the limit value specified in table 2.
Safety will not be guaranteed if the above-mentioned provision
is not provided.
