The JIB CRANE, with manual rotation, in "column" and "wall" versions are designed for handling local goods within a plant, a working area or for use in operational positions.
They have three functions:
RAISE the load vertically in space, using the hook of the lifting unit, generally consisting of a chain or electrical hoist or using the suitable accessories for this operation;
TRANSPORT the load using an electrical or manual hoist trolley which flows along the radial axis of the crane arm;
ROTATE the load in space, around the connection axis of the arm, using a manual push action of the load, serving the circular area underneath it, bound by the rotation range of the arm.
The jib cranes with "COLUMN" are generally designed to be fixed to the ground, the column is self-supporting and can be fixed to the ground using anchor bolts, on a foundation plinth or, in special cases determined after checking the feasibility, even with expansion or chemical fixing.
The jib cranes with "WALL" are generally designed to be fixed to an existing structure (pillars, walls, machine bodies, etc.), through a system of brackets and bolts or screws or, after verification, with expansion anchors or using chemical fixing.
Note: We can also supply column cranes with motorized swivel function for higher loads, heights and outreaches. These machines, often used for housing boats, were built with capacities up to 25 tons - jib lengths of 8 m with spread double arms and split lifting hoists: 12.5 + 12.5 ton. In this case the "marine" version is equipped with accessories and "treatment" for the highly corrosive environment.
