11 Lubrication
11.1 Drive gear
The drive gear has been filled with gear oil in the manufacturing plant. The lubrication of the drive gear is meant for
its entire lifetime.
An oil change is needed:
• If the electric chain hoist was subjected to a general overhaul;
• If there is visible leakage;
• If the air-bleed valve is blowing off strongly;
• After each time the drive gear has been opened.
Make sure to always have a sufficient quantity of oil in the drive-box.
Oil change:
There is one screw on the bottom of the drive-box for bleeding the oil and one on top for filling oil into the drive gear.
Gear lubricant oil used: Mineral oil; viscosity of 220 mm²/s at a temperature of 40°C.
The following table contains the quantity of oil to be filled:
