11.1
Checks before the initial start-up
Lifting gear
Load chains must not be twisted.
Lubricate the load chain with gear oil or suitable chain lubricant before first loading.
Trolley drive
The open-lying teeth of the trolley drive must be lubricated.
Hand gear for hand geared trolley
Ensure correct fit of the hand chain, it must not be twisted and must hang freely.
11.2 Functional
test
Lifting gear
Check lifting and lowering functions, initially without a load. The buttons of the control switch are marked with
the symbols for lifting and lowering. The movement direction of the load (lifting or lowering) must correspond
with the push buttons (lifting or lowering). This is the factory setting.
If the device lowers when the “lift” button is operated and lifts when the “lower” button is operated, the two
phases of the net connection must be swapped.
The function of the end switch is to be checked initially by operating the end switch by hand. Then carefully
move to the end position. If required, adjust end switch.
Then check the brake function under load. After releasing the buttons of the control switch, the load must be
securely held.
Trolleys
Carefully move the trolley to the end positions and check the positions of the end stops.
NOTICE!
The limit switch function will only work if the movement direction of the load (lifting - lowering) corresponds
to the push buttons of the control switch.
12 Maintenance
12.1 General
All monitoring, servicing and maintenance operations are to ensure correct functioning of the equipment;
they must be effected with utmost care.
Only “qualified persons” may do this work.
Servicing and maintenance work must only be done when the hoist is not loaded.
Records must be kept of all test results and measures taken.
12.2 Monitoring
The monitoring and servicing intervals stated are valid for operation under normal conditions and single-shift
operation. In case of severe operating conditions (e.g. frequent operation with full load) or special
environmental conditions (e.g., heat, dust, etc.), the intervals must be shortened correspondingly
12.3
Replacing the load chain
CAUTION!
If there is any visible damage and when the conditions for replacement are reached (i.e. one or several
dimensions in the table have been reached, there is corrosion or elongation), the chain must be replaced.
When replacing the chain, also check the chain wheels.
