The gantry crane is not restricted by the workshop steel structure, and owing to the simple structure and covenient installation, it is suitable for various working conditions.
High strength, good rigidity and high stability, low cost. It is one cost-effective crane solution!
MH type electric hoist gantry crane is designed and manufactured in accordance with national and industry standards such as GB/T3811-2008 "Crane Design Specification" and JB/T5663-2008 "Electric Hoist Gantry Crane".
It is one workshop lifting equipment, which uses CD MD electric wire rope hoist or electric chain hoist as the lifting mechanism. It can be used indoors and outdoors, such as the docks, freight yards, warehouses, and construction sites. The single girder gantry crane is mainly composed of steel structure gantry, crane traveling mechanism, electric hoist, and electric control system.
Normally, single girder gantry cranes are most widely used and often in open storage yard. Considered the high quality, we ensure the gantry cranes price we offer is not the lowest but the most reasonable.
As one of the experienced gantry crane manufacturers, we can produce different specifications of the crane.
The main beam is the crane's main load-bearing component, and the running track for the electric hoist. It is a triangular beam is weld by a support frame(welded by angle steel and other section steel) and an I-beam. The main beam is made into an upper arch according to the requirements, and the upper arch F should be (1/1000～1.4/1000)S. The two sides of the span are designed with saddles connected to the outriggers, and there are rectangular steel plate connecting flanges. There are buffers at both ends of the main beam to ensure the safe operation of the trolley on the main beam.
The lower beam is also a box-shaped structure, mainly composed of cover plates, webs, ribs, flange supports and other parts. The production process is similar to that of the main beam and other box beams. After the lower beam structure is completed, the bent plates are assembled according to the drawing. The flange support is welded to the lower beam after the lower beam is made to ensure the level of the flange surface. When the lower beam and the leg are assembled, the flange on the flange made on the leg is welded to the leg.
The appearance quality and geometric dimensions of the lower crossbeam after production meet the requirements of the standard GB14406-93.
It is a triangular beam is weld by a support frame(welded by angle steel and other section steel) and an I-beam.
The A-shaped structure increases the strength, rigidity and stability of the gantry frame. The steel plate flange between the leg and the ground beam is connected by bolts. The structure is simple, the installation is convenient, and it is convenient for transportation and storage.
The electric hoist will do dynamic and static load tests, as well as ascending and descending pressure tests. The baking paint process is used to enhance the adhesion of the paint film and improve the appearance quality. The assembly line ensures product quality.
The crane traveling mechanism is driven separately, mainly composed of: operating motor, operating reducer, wheel set, etc. The motor adopts a soft-start motor, with its own brake, and the brake is reliable; The reducer adopts vertical gearbox to save space; LDA-type wheels, double-wheel edges, are not prone to wheel climbing and falling off.
The hoist power supply is the cable type, and the slideway can use wire rope slideway, I-steel slideway, and special-shaped steel slideway;
The crane powersupply can be powered by a cable drum, buss bar, etc.
Can use control handle with pendant line, wireless remote control, or cabin control.
Phase failure protection, fire limit, crane travel limit, heavy hammer limit-lifting height limit, overload limit, etc.
