5.8 Hoisting gearbox
The hoisting gearbox comprises multistage spur gear transmission. The lubricant for the hoisting gear is
semi-fluid grease. When used in conformance with the operating group classification of the hoist, the
gearbox lubricant does not need to be changed during the Safe Working Period (SWP). If the hoist is
operated in extremely cold conditions, the factory-installed grease must be replaced with synthetic
transmission grease. Refer to the section “Lubricants” for further instructions.
