Inspecting the deflection roller crosshead

Only with wire rope hoist with hoist drive GM 5000 or GM 6000

On a wire rope hoist with a hoist drive GM 5000 or GM 6000, the deflection rollers are fitted in the trolley frame with a measurement bolt. A retainer is also fitted over the deflection rollers.

 

   Inspect the deflection roller crosshead.
The drilled holes must not exhibit any cracking or other damage.

   Inspect the deflection roller.
It must not exhibit any deep grooves or heavy wear.

   Check the deflection roller crosshead suspension.

The supporting structure must be sufficiently lubricated so the deflection roller crosshead can move back and forth.

   If components are missing or damaged: replace the components.

See Replacing the deflection rollers.

 

 

Only with wire rope hoist with hoist drive GM 7000

On a wire rope hoist with a hoist drive GM 7000, the deflection roller crossheads are installed in the trolley frame. The deflection roller crossheads are also covered by a plate.

 

	Plate
Rib screws M10x16

   Release the rib screws M10x16 (4x) on the plate.

   Lift the plate off the trolley frame.
