Manually Rotated Jib Cranes

“C” Channel version:

• for lifting capacities from 63kg to 1000kg
• jibs from 2m to 7m
• Manually rotated
• 300° Slew
  
• The arm is made using a special section bar made of folded sheet metal, inside which the hoist-carrying trolley run.
• The arm is fitted with one or two staybolts which support the profile and connect it to the rotation tube.
• This version is characterised by the extreme ease of handling due to the low inertia derived from its own reduced weight.
• The arm is normally fitted with a special “channel” profile trolley, which allows it to be pushed with maximum fluidity.
• Our jib cranes are designed and manufactured according to the ISO A5 classification.

The manually rotated jib cranes in the GBA”column” series are designed for the handling of goods inside a plant, in a square or to serve operative positions. The standard models are available for lifting capacities from 63kg to 2000kg and jibs from 2m to 8m The C version (this page, see above); T versions and H versions are designed according to the three different versions of the arm.

The column crane can be supplied, on request, with a main on/off line switch which can be padlocked. The distribution of energy takes place via a flat festoon cable which slides on trolley along the arm.

Warning!
The fixing of the column using chemical bolts, needs a scrupulous check of suitability in relation to the type of support flooring. The suiability checks are the responsibility of the user and must be carried out by an expert, qualified technicians who will evaluate the feasibility and formally assume the relative responsibilities.

Base Plates

Note: The foundation frame with logbolts, used in the column-mounted version for fixing the column itself to the foundation plinth is supplied on request.
