Electric Rotary Jib Crane
Main structure of cantilever hanging:
(1) The column is made of steel pipe, and the lower end is fixed on the concrete foundation. On or connected to the bottom plate, the anchor bolts or chemical bolts are used for connection.
(2) The rotary arm adopts KBK track, I-beam, H-beam or box beam welded by steel plate. The structure is simple, the strength and stiffness are high, the technology is good, and it can be applied to the installation and operation of all kinds of chain hoist. Movable stop is installed at both ends to ensure that the hoist works within a specific trip.
(3) The rotary driving device adopts seamless steel tube as the shell, and the inner self-allocating roller bearing is installed, which can realize the cantilever free rotation. Due to the self-allocating roller bearing's own performance, even if the concentricity of the waist ring and the column is slightly deviated, it can also ensure the safe and normal use of the cantilever hanging.
(4) the cantilever crane electrical can be single/double speed or frequency conversion control, 36V low voltage control, the control of the integrated block is easy to install, easy to maintain, the brake automatic adjustment and dustproof, frequency conversion control can reduce the load swing, the implementation of soft start speed range is wide, with a number of protection.
Technical personnel according to different schemes, different sites, different products, design for the production work needs of the cantilever, not only
Improve the safety in the production process, and save manpower, material resources and financial resources, improve work efficiency.
