The electric slewing crane is a GBR series jib crane.
Jib cranes are generally used to make workstations and operating machines independent, without the need for additional personnel and without relying on shared lifting or transport systems.
A necessary investment to achieve high productivity, ensuring continuous labor cost savings and reducing downtime, allowing for a rapid return on investment.
A wide range of configurations enables us to provide customers with the most suitable and efficient solution for increasingly evolving operational needs.
In many cases, jib cranes represent the only feasible solution when other lifting and handling systems cannot be used.
ROTATING ARM
Manufactured, depending on capacity and outreach, either in steel beam with standardized profile or in box-section beam with internal stiffening diaphragms.
Like the column, it is equipped with a drilled flange designed for the installation of the slewing ring, to which it is connected using high-strength bolts.
COLUMN
Self-supporting steel column with special circular and/or octagonal profile, ensuring excellent rigidity.
The column is also equipped with a base plate for anchoring to the foundation, and at the top end with a drilled flange designed for the installation of the slewing ring.
SLEWING MECHANISM
Composed of a base axial bearing (slewing ring) capable of withstanding both vertical loads and overturning moments, and a gear motor mounted on the arm.
The motor is self-braking with smooth start and progressive braking; its pinion, mounted on the low-speed shaft, engages with the internal gearing of the slewing ring.
The assembly system, combined with the precision of the slewing ring and the sensitivity of the gear motor, ensures smooth and precise arm rotation.
The cranes can be equipped with wire rope hoists and/or chain hoists.
