Add a knee joint in the open position and lock it with quick release bolts.
The knee joint allows the ladder to be bent to fit the shape of the roof, regardless of the slope, or to enter
an opening.
Prepare the base of the unit, making sure that the floor surface is level. If the floor is wet and loose, install
the unit onto boards. The base of the structure of the hoist must be solid and durable.
The ladder shoes must be anchored to the ground using dowels or fixing plugs adapted to the type of
support. The dowels or fixing plugs must have a minimum diameter of 12 mm.
For up to 8 m of ladder length, hoist the unit with 2 people on the ground. From 8 to 15 m of ladder length,
hoist the unit with 2 people on the ground and 1 person on the roof pulling on a rope attached to the end of
the ladder (the person on the roof must wear a safety harness with fall arrest system).
Alternative solution: The ladder is lifted by 2 to 3 people on the roof by means of a rope or manual winch.
The ladders will then be slotted in and locked one after the other from the bottom of the ladder by 1 person
on the ground. People on the roof must wear a safety harness with a fall arrest system anchored to a
dedicated part of the building.
The structure and equipment of the hoist must not be used as an anchoring point for the safety
harness.
