L type gantry crane /single girder gantry crane
Product Description
Electric Hoist Gantry Crane is light type gantry crane take CD electric hoist or MD electric hoist as lifting mechanism, through lifting mechanism - electric hoist hook moves up and down, trolley moves left and right and the crane back and forth traveling combined forming the stereo work space, to achieve movement, flip and other operations of the lifting objects.
Hoist gantry crane is single girder gantry crane, can be divided into L-type and A-type hoist gantry crane according to the leg shape. Light weight, simple mechanism, easy to operation, widely used in docks, freight yard, warehouses, construction sites and other conditions.
Hoist gantry crane working-level is A4, generally used for outdoor work, the crane and trolley lifting mechanism both set with rain cover.Features
Hoist gantry crane mainly consists of gantry frame structure, crane traveling mechanism, electric hoists lifting mechanism and electrical control system.
Gantry Frame Structure
Gantry frame mainly consists of: main beam, ground beam, legs, ladder platform, driver’s cabin and other components.
Main beam is the main bearing carrier of hoist crane, and also the track of hanging electric hoist. Main beam made by Q235 or Q345 steel rolling into U-shaped groove, oblique cover plate, ribs and I-beam welding into plain girder or with steel plate welding into box girder. Electric hoist trolley runs on the I-beam flange. On both sides of main girder span position designed with saddle seat connected the legs, and there is a rectangular steel connecting flange. Both ends of the main beam has buffer to ensure that trolley running on the main beam safely.
Ground beam is basis of bearing the main beam and load, and it is also the tie of main beam and traveling mechanism, is one of the main bearing member of crane metal structure, mainly made by U-shaped groove and steel welding or steel plate welding into box-shape structure, with compact structure, good rigidity, good appearance, good welding performance and other characteristics. The end of the ground beam is provided with buffer.
Leg is isosceles trapezoid box or right-angle trapezoidal cross-section column welded by Q235 or Q345 steel plate, column up and down welding with different width flange. The upper flange is wide; while the lower flange is narrow, to increase the strength, rigidity and stability of the gantry frame. When the crane span is more than 30 meters, it will be designed with a pair of flexible legs to improve crane traveling.
the main beam and the saddle seat symmetrical arranged on both side of the main beam fastened two flanges by bolts, and make the distance between the two legs with narrow above and wide below, that forms "A"-shaped structure, improve the stability of the crane. Steel flange between leg and the ground beam connected by bolts. This structure is simple, easy to install, easy to transport and storage.
Crane Traveling Mechanism
Crane traveling mechanism mainly consists of: running motor, running gear, wheel set and other components. It is also divided into different structural forms-A type and B type depending on different lifting tonnage. The whole crane driving set is with simple structure, low noise, generously appearance, safe and reliable operation, easy installation and maintenance.
A type structure form
Motor: traveling mechanism using ZDY series brake motor, the motor comes with brake, brake is reliable.
Reducer: using LDA or LDH type reducer, reducer width is small, no couplings;
Wheels: Using LDA-type wheel, double wheel rim, less prone to wheel climb off road track fault; ground beam end plate use bolt connection, removable, easy installation and maintenance;
Rail sweep: set up with rail sweeping, clear obstacles on the track, to ensure safe operation.
Rail clamp: outdoor installation equipped with rail clamp, which can effectively prevent the crane slip move due to external force.
B type structure form
Motor: crane traveling mechanism using YZR series crane and metallurgical wound rotor motor, strong overload ability, large output torque.
Reducer: using separately driving type, using ZSC or ZSC (A) vertical reducer, saving space, large reduction ratio range, high transmission efficiency, smooth operation, low noise, easy installation and dismantling.
Brake: Installation YWZ electric hydraulic block brake between the running motor and reducer. Brake smooth, high operation frequency, safe and reliable performance. Without lubrication during operation, high transmission efficiency, long life, safe and reliable, easy to replace, environment protecting.
Coupling: Set up with coupling between brake, reducer and motor, to connect the three reliably.
Wheels: Using double wheel rim cylindrical wheels, less prone to wheel offset and slip; with 45-degree split structure, removable, easy maintenance and installation;
Rail sweep: Equipped with rail sweeping, clear obstacles on the track, to ensure safe operation.
Rail clamp: outdoor installation equipped with rail clamp, which can effectively prevent the crane slip move due to external force.
