INSTALLATION AND USE OF SHORING ACCESSORIES
BASE LADDER PROP 2 TO 3m
The base ladder prevents the ladder structure from bowing when the mobile equipment is loaded. It can be
attached to any rung of the ladder structure. The hinged base crossmember can be supported on the floor,
on a window sill or on a balcony floor. It must be always anchored to the ground using dowels or fixing
plugs adapted to the type of support. The dowels or fixing plugs must have a minimum Ø of 12 mm and
pass through the holes provided for this purpose in the hinged base crossmember. The anchoring to the
ground must be solid and durable.
The base ladder prop is extendible from 2 to 3m.
Installation:
- Stretch the base ladder prop 2 and 3m by pressing the locking handle (1) until the headboard prop
reaches the vicinity of the ladder to which it will be attached. Be careful not to stretch the base
ladder prop more than 1 metre, as the red area of the rung must not be visible under any
circumstances.
- Bring the base ladder prop in line with the previously installed ladder structure (2).
- Open the lock by pulling on the rope (3) and then hook the headboard prop onto the rung (4). Lock
the hook by releasing the rope.
