Slide the two assembly rollers under the lower end carriage.

The tapered rests of the assembly rollers go underneath the end carriage.

The lower end carriage is the same on both sides. It therefore makes no difference which side (left or right on the end carriage) the assembly rollers are fastened on.

    Secure the two assembly rollers with lashing straps.

    Turn the end carriage on its side with the assembly rollers.

    Place both A-frames on the bolted flange of the lower end carriage.

The A-frames are inclined slightly toward the centre of the end carriage. The diagonal braces will later point toward the inner side of the crane.

    Temporarily bolt on the A-frames with the M16x40 rib screws (4 on each).

Only for 350 mm trolley:
Temporarily bolt on the A-frames with the M16x40 rib screws (6 on each).
