Replacing an old style rope guide with a heavy-duty rope guide
When replacing an old style rope guide with a new style rope guide in true vertial lift hoist or machinery
hoist, the hoisting limit switch setting for the hook’s lower position may need re-adjusting to ensure safe
operation. See the drawing below to identify the type of rope guide you have on the hoisting unit.

A. Old style rope guide
B. New style rope guide
1. Stainless steel rim at the bottom of the drum groove
2. Plastic support element
3. Straight front face plate
4. 60mm wide cast iron rim around the rope drum
5. Spring loaded rim joint
6. Roller bearing support assembly
The heavy-duty rope guide cannot travel as close to the rope fixing clamps on the rope drum as the old
style rope guide. It takes approximately 10mm more space in that direction. After installing the heavy-
duty rope guides, adjust the hoisting limit switch so that there is a minimum of 15mm gap between the
rope guides and the rope fixing clamps when the hook is in its lowest position (see drawing below). Test-
drive the hoist and re-adjust if necessary.
