Electric Hoist Gantry Crane

Electric hoist gantry crane is mainly used for outdoor yard, yard goods, bulk cargo handling operations. Gantry cranes are widely used in port yard due to high utilization rate, wide range of operation, wide adaptability and strong versatility.

Electric hoist gantry crane mainly has three types, single girder type, double girder type and semi gantry crane. Single girder gantry crane is suitable for light duty, double girder crane is reliable for heavy duty. Semi gantry cranes have legs on only one side and another side supporting the plant or factory.

Our group, a well-known crane supplier in China, provides types of gantry cranes for sale, such as light duty crane, heavy duty crane, RTG gantry crane, RMG gantry crane, port container gantry crane. If you are interested, just send email to sales@crane.pk

Except for gantry crane, we also have other industrial machine, electric flat transfer cart, wall traveling jib crane, boat travel lift, overhead crane, construction winch, marine winch.

Types of electric hoist gantry crane

For girder, gantry crane mainly includes single girder type and double girder type.

Single girder gantry crane is simple in structure, easy to manufacture and install, with small mass. Compared with the double girder gantry crane, the overall stiffness is weaker. Therefore, when lifting weight Q≤ 50t and span S ≤35m, this form can be adopted. Single girder crane gantry legs have L and C two forms.

The L type is easy to manufacture and install, with good stress condition and small quality. However, the space for lifting goods through the supporting leg is relatively small. The legs of type C are inclined or bent so that there is a large horizontal space for goods to pass through the legs.

Double girder gantry crane has strong bearing capacity, wide span, overall stability, variety. Compared with single girder gantry crane with same weight, double girder gantry crane has heavier weight and costs more. According to the different structure of main beam, it can be divided into box beam and truss. Generally, box structure is adopted.

Application of electric hoist gantry crane

General gantry crane adopts the box type and the truss type structure. It can carry all kinds of articles and bulk materials the lifting weight is below 100 tons, the span is 4 ~ 39 meters. The ordinary gantry crane with grab bucket has higher working level. General gantry crane mainly refers to hook, grab, electromagnetic, hoist gantry crane, also including semi gantry crane.

Hydro-power station gantry crane is mainly used for lifting and lifting gate, also can be used for installation work. The lifting weight is 80 ~ 500 tons, the span is small, 8 ~ 16 meters; Low lifting speed, 1 ~ 5 m/min. Although this kind of crane is not often lifted, but once the use of the work is very heavy, so it is appropriate to improve the level of work.

Shipbuilding gantry crane is used for assembling the hull of ship berth, two lifting trolleys are usually available: one has two main hooks and runs on the track of the flange on the bridge; The other, with a main hook and a secondary hook, runs on rails at the lower flange of the bridge to flip and lift large hull sections. The lifting weight is generally 100 ~ 1500 tons; the span is 185 meters; the lifting speed is 2 ~ 15m/min, and there is 0.1 ~ 0.5m/min fretting speed.

Container gantry crane is used for container terminal. After the trailers transport the containers unloaded from the ship to the yard or the rear of the quayside container carrier bridge, they are stowed on the gantry container cranes or directly loaded onto the trucks and transported away, which can speed up the turnover of the container carrier bridge or other cranes. Container yard that can pile up high 3 ~ 4, 6 rows wide, generally uses tire type, also rail type. Compared with container straddle truck, container gantry crane has larger span and height on both sides of gantry. In order to adapt to the transportation needs of the port, the working level of this crane is higher.
