2 DESCRIPTION OF THE MACHINE AND TECHNICAL
INFORMATION
2.1 The jib cranes with manual/electric rotation
2.1.1 Intended use - Expected use - Intended purpose
The jib cranes,
manually/electric rotated, in GBA-CBE series pillar-mounted model or GBP-MBE series
wall-mounted model, are produced to move goods within the plant.
Jib cranes
have three functions:
•
they lift
the load vertically in space, via a hook on the lifting unit, generally composed of a manual
or electric chain hoist and using accessories suitable for this operation;
•
they traverse
the load in space, with the assistance of an electric or manual hoist holder trolley,
which runs along the radial axis of the crane arm;
•
they rotate
the load in space, around the constrained axis of the arm, through a manual push
action of the load using the circular area below, limited by the rotation radius of the arm.
2.1.2 Installation restrictions
The GBA-CBE pillar-mounted jib cranes
are intended to be fixed to the ground, the pillar is self-
supporting and can be fixed to the ground using log bolts, on a foundation plinth or in special cases having
checked suitability, also with screw anchors or dowelling.
The GBP-MBE wall-mounted jib cranes
are intended to be fixed to an existing structure (pillars, walls,
machine casing, etc), using a system of brackets and staybolts, either with fixing screws or, subject to a
check, with screw anchors or dowelling.
In both cases (pillar-mounted and wall-mounted cranes) the user MUST check, directly
or using specialised staff, the suitability of the surfaces to be fixed on. These surfaces
must guarantee the stability and safety of the crane in all its working conditions,
supporting the lifting operations and the dynamic effects of the tilting momentum and
of the type and speed of lifting
