High level Slewing Overhead Crane with Carrier-Beam,Overhead Crane

Feb 01, 2024

Profile

The crane has rotating hanging beam, suitable for steel, storage yard, warehouse, outdoor fixed span, loading and unloading steel plate, shaped steel, coil and other materials. It is especially suitable for lifting different specifications and requiring horizontal rotation. The electromagnetic sucker, clamp and other special sling can be carried under hanging beam. 

Components

The Upper Rotating Hanging Beam Crane is a kind of crane which can drive the hanging beam rotation through the upper trolley rotation; the fixed electromagnet on the hanging beam to absorb and carry heavy objects. The electromagnetic hanging beam rotation angle be drove by the upper trolley is: 0～270°; it can meet the requirements of material turning, cross stacking and so on. The Upper Rotating Hanging Beam Crane is mainly composed of bridge frame, crane running, trolley, electromagnetic hanging beam, cab and electrical equipment.

-Bridge Frame

The bridge frame is the main force component of the crane. The double beam with double track structure is adopted. The main beam and the end beam are the main force parts, and the auxiliary metal structure is composed of trolley track, walking platform, railing, ladder and so on.

The main weld by submerged arc welding or gas welding; after welding, the welds are detected according to the regulations of ‘GB/T 14405 - 2011 general overhead crane’. The main force material is Q235B, and the main beam section is analyzed and calculated by finite element method to ensure that it has sufficient strength, stiffness and overall stability.

All steel plates did ball blast pretreatment, reaching Sa2.5 grade standard. The camber ratio is (0.9 ~ 1.4) S/1000, and the maximum camber position is controlled in the middle of the span 1/10. The end beam is a box structure, and the end beam is connected with the main beam as rigid connection. The end beam needs to be transported after disassembly, and it is connected by high strength bolts, and the connection plate is positioned by reaming bolts. The walking platform of bridge with 3mm thick tread plate, channels are set up for 1050mm high railing, with a distance of 350mm for horizontal bar, the bottom height of retaining plate is 100mm, any place on the railing can withstand the load of 1kN (100kgf) from any direction without plastic deformation. In order to facilitate transportation, loading and unloading, installation, the main components are equipped with hoisting lug, hoisting hole, etc., the hoisting lug, hoisting hole strength and location need to fully consider the safety and convenience of lifting.
