6.9 Travel motor brake

See operating instructions for travel motors

6.10Oil change

Dispose of used oil in accordance with environmental regulations.
• Change oil while warm if possible.
• See "Technical data" for suitable types and quantity.
• Replace copper gaskets.
• Screw down oil drain plug (2) and oil filling plug (1) (10 Nm).

6.11 General overhaul     

The drive mechanism (motor and gear; does not apply to wearing parts) of the ST 
chain hoist is classified in accordance with FEM 9.511. The theoretical full load life-
time in hours shown opposite (D) is applicable for normal hoist applications.
If the full load lifetime (D) minus the lifetime expired is nought, the chain hoist must be 
overhauled by the manufacturer.
The chain drive is classified in accordance with FEM 9.671.
Components which are in the power flux may only be overhauled by the 
manufacturer.

6.12 Trolley    

Wheels, wheel drive and runway

•  Visual inspection of wheels for wear. Replace if original diameter is reduced by 

max. 5%.

• Visual inspection of runway beam for wear.
    The running characteristics can be improved by a guide system. This avoids wear 

and the flange play can be reduced.

• Inspection of flanges for wear.
    A high degree of wear on the flanges indicates that the trolley is canting or running 

heavily on one side. The cause must be ascertained and eliminated. 

6.13 Operating hours counter

(Option)

The operating hours counter fitted measures the hoisting time only, thus the value 
measured must be doubled.

Example: 

123 h measured; 246 h to be recorded
