4.6.3.2 Explanation and dimension of attachment 4.6.3.2.1 Explanation

A complete frame is composed of:1 front girder (1), 1 rear girder (2), 2 lateral girders (3) and (4), 1 diagonal bracing (5), 2

brackets (6) and (7) equipped with 2 shims (8) and 2 wedges (9) and fitted onto the diagonal bracing (5), 2 brackets (10) and (11), 4 taper keys and various fixing shafts.The front girder (1) has 4 holes in order to allow the fixing of the frame with the building by means of the shafts (13).

4.6.3.2.2 Main dimension of 2m attachment

4.6.4 Installation of 2m attachmentRemove the standard ladder from the mast section which will be equipped with the anchorage

frame. On the ground, place the two lateral girders (1) and (2) onto the front girder (3) (insert shaft (4) only in order to make the spacing of the girders (1) and (2) easier) (Detail A and B- Figure 1).

Sling and raise the assembly until it reaches the right position on the mast (with the side of the anchoring beam attachment (3) towards the building) (Detail A-Figure 1). In order to make fitting easier, use 2 cords for guiding.

Rest the gussets (5) of the front girder (3) onto the horizontal bracings (6) located in the middle of the mast section (Detail C- Figure 1).

Fold back the lateral girders (1) and (2) and pin−connect the shafts (7) (Detail A and B − Figure 2).

Sling and raise the lateral girder (8), position it and pin−connect it to the rear girders (1) and (2) using the shafts (9) and (10) (Detail C and D − Figure 2).


Edition 00 – 01/2014

Raise and place the bracket (11) equipped with the shim (12), then pin−connect it onto the girders (1) and (2) by means of the shafts (13); fix with split pins (Detail A and B − Figure 3).

Raise and place the bracket (14) equipped with the shim (15), then pin−connect it onto the girders (16) and (17) by means of the shafts (18); fix with split pins (Detail A and B − Figure 3).

Place and pin the diagonal bracing bar (23); pin−connect it onto the brackets (19) and (20) by


Edition 00 – 01/2014

means of the shafts (24) (Detail C − Figure 3).

Check the level of the frame, readjust if required.Place the outer wedges (25) and act on them in order to bring the frame into contact with the

mast uprights (Detail A − Figure 4).Place the inner wedges (26) and drive them in so that the shim (27) comes hard against the

inner side of the mast uprights (28) (Detail A − Figure 4).Having carried out these operations, check that there is no play remaining between the

wedges and the mast uprights.Fit the ladder (29) supplied with the frame instead of the standard ladder, then equip it with its

two back loop parts (30) (Detail B − Figure 4 ).
