accessible, due to a wall or other obstacles, follow option B instead of option A. To install the hoist
trolley unit properly, the following steps shall be taken in sequence.
Option A, Driving the hoist trolley unit onto the monorail:
‐

wheels just above the bottom flange of the monorail.
Attention! Watch for the orientation of the hoist trolley unit.
‐
Push the hoist trolley unit onto the monorail.
‐
Reinstall the end stops onto the monorail.
Option B, Demount and lift the hoist trolley unit onto the monorail:
Standard headroom
To install a standard headroom hoist trolley unit, the trolley shall be partly disassembled,
lifted up to the monorail and reassembled using the following steps.
