If there is a defect, the hoist motor can be disassembled from the hoisting gear and replaced individually. Because of the modular construction, the hoisting gear does not need to be disassembled.

The images show the replacement on a pole-switchable GM 6000 hoist drive. The replacement of a hoist motor in a different size or on a four-pole hoist motor does not essentially differ.

Preferred option: Hoist motor vertically disassembled toward the top:

The safest option is disassembly of the hoist motor vertically toward the top from a hoist drive that is lying down. For this, the hoist drive must first be disassembled from the wire rope hoist. This option should preferably be selected when possible.

   Disassemble the hoist drive.

   Turn the hoist drive and lay it on the gear unit.

Alternatively: Support the hoist motor horizontally from below:

The hoist motor can be replaced horizontally if the hoist drive is mounted on the wire rope hoist. Depending on the accessibility on the wire rope hoist, the hoist motor may need to be supported from below, e.g. with a suitable forklift.

During replacement, the hoist motor must be secured so that the weight can be safely held.

Alternatively: Secure the hoist motor horizontally from above:

Depending on the installation situation, the hoist motor can also be replaced horizontally while being held from above. For this, a movable slinging point is attached in the housing of the hoist motor. Since the cable drum housing is located directly above the hoist motor, the slinging point is usually not easily accessible.

The images show the replacement on a vertically positioned hoist drive.

   Unscrew the rib screws (3x) of the fan cover.

   Take off the fan cover.

   Only with fan blades on the motor shaft: Screw a suitable eyebolt into the motor shaft and sling suitable lifting tackle in the eyebolt.

   Only with auxiliary fans: Disassemble auxiliary fan and screw an eyebolt into the motor shaft.

If no eyebolt can be screwed into the motor shaft: Use suitable lifting tackle with which the hoist motor can be lifted vertically.

   Release the rib screws (4x).

   Lift the hoist motor.

●   The coupling halves between hoist motor and hoisting gear slide apart.

●   The hoist motor is disassembled.

The images show the replacement on a vertically positioned hoist drive.

   Bring the hoist motor over the hoisting gear.

   Turn the hoist motor so that the connector housing faces the exterior of the subsequently mounted hoist drive.

   Insert the coupling star on the coupling half on the hoisting gear.

   Turn the coupling halves on the hoisting gear so that the coupling halves from the hoist motor and from the hoisting gear lie exactly over one another and mesh into each other during the assembly.

In the case of a removed hoist drive, the coupling half on the gear unit can be turned.

   Insert the hoist motor on the hoisting gear.

●   The coupling halves slide into each other in the coupling star.

   Tighten the rib screws (4x) on the hoist motor.
