Inspecting the fixed point on the fixed point crosshead (rope socket and rope wedge)

 

The pictures show the procedure on a GM 1000 modular wire rope hoist. The procedure on GM 800 does not differ significantly from this.

 

Rope socket

Rope wedge

Dead end rope grip

Wire rope

*   Measure the rope wedge protrusion (lower edge of rope wedge to lower edge of rope socket).

*   Measure the rope clamp spacing (upper edge of dead end rope grip to lower edge of rope wedge).

*   The measured values must not be higher than the values in the table.

GM 800

18 mm

6.5 mm

GM 1000

3 mm

8 mm

Additional information: The minimum rope clamp spacing specified is always exactly equal to the wire rope diameter of the wire rope hoist.

*   If the rope wedge protrudes too far out of the rope socket, or if the dead end rope grip is too close to the rope wedge: replace rope socket and rope wedge. See Replacing the wire rope, cable guide, rope socket and rope wedge.
