The braking device of the arm:
It is made up of a clutch system with asbestos-free material, which allows the regulating of the rotating
strain of the arm and ensures its positioning stability (fig. 6).
The electrical system:
It is intended for the electrical input of the hoist and/or trolley (if electric) which slides along the arm of the
crane (fig. 7). It has a connector block, situated on the top of the pillar-mounted jib crane or on the arm
support of the wall-mounted jib crane, for the connector between the line and the festooned cable.
The distribution of energy uses festoon-cable which does not spread flames, generally of the flat type,
sliding on
suitable coasters or sleds that slide the whole way along the arm, inserted in the arm or in a special channel.
Foundation frame with log bolts:
This is supplied on request in the pillar-mounted version, for the fixing of the pillar itself to the base
(foundation plinth) (fig. 8).
Brackets and staybolts unit:
Used for fixing to a pillar in the wall-mounted version, it is available on request. It is fitted with a system of
pressure screws to guarantee the best adherence of the staybolts to the pillar (fig. 9).
