FEM Standard 80Ton/10T Double Girder Gantry Crane for Construction

crane supplier

Nybon Machinery is a leader in providing overhead crane/bridge crane,gantry crane,jib cranes,ship cranes,electric winches,hydraulic winches,diesel winches,electric hoist and relative components for shipyard,automotive,material handling, specialty machinery, and workshop solutions. Our diverse portfolio also includes a wide range of lifting products for industrial, commercial and specialty applications.

A double box girder gantry crane is an overhead crane built on top of a structure that is supported by freestanding legs, eliminating the need for an overhead runway system. Gantry cranes are built on movable frameworks with wheels that enable the structure to be moved along a track or rail system.

Double Box Girder gantry cranes are designed with two girders configuration, providing various load capacities. Double box girder gantry crane are used to lift extremely heavy loads.

Nybon Double Box Girder gantry crane are designed with the highest engineering standards for safety and high performance by advanced technology.Nybon manufactures and supplies custom double girder gantry crane with the capacity up to 300 tons and span up to 50 meters for your demands.

Brief introduction of gantry crane?

Gantry crane is a variant of bridge crane, also known as gantry hoist. It is mainly used for the loading and unloading of outdoor cargo yards, stockyards and bulk cargoes.

Gantry cranes have the characteristics of high site utilization, large operating range, wide adaptability and strong versatility, and are widely used in port cargo yards.

Its metal structure is like a door-shaped frame, and two feet are installed under the main beam, which can walk directly on the track on the ground, and the two ends of the main beam can have outstretched cantilever beams.

General features of gantry crane:

Gantry cranes (also known as gantry cranes) are bridge-type cranes in which the bridge is supported on the ground track by the outriggers on both sides.

Structurally, it consists of a gantry, a cart running mechanism, a hoisting trolley and electrical parts. Some gantry cranes only have outriggers on one side, and the other side is supported on the workshop or trestle, which is called a semi-gantry crane.

The upper bridge frame of the gantry crane (including the main beam and the end beam), the outriggers, the lower beam and other parts are composed.

In order to expand the working range of the crane, the main beam can extend beyond the outriggers to one or both sides to form a cantilever. A hoisting trolley with a jib can also be used to expand the crane’s operating range through the pitch and rotation of the jib.

ajor products of Nybon gantry cranes

1. Single beam

The single girder gantry crane has a simple structure, is easy to manufacture and install, and has a small weight. The main girder is mostly an off-track box frame structure. Compared with the double main girder gantry crane, the overall stiffness is weaker. Therefore, when the lifting weight Q≤50t and the span S≤35m, this form can be adopted. Single main girder gantry crane gantry legs are available in two forms: L type and C type. The L-type is easy to manufacture and install, with good stress and low weight. However, the space for lifting goods through the outrigger is relatively small. The legs of the C-type are inclined or curved in order to have a large lateral space so that the goods can pass through the legs smoothly.

2. Double beam

The double main girder gantry crane has strong bearing capacity, large span, good overall stability and many varieties, but its own quality is larger than that of the single main girder gantry crane with the same lifting capacity, and the cost is also higher. According to the structure of the main beam, it can be divided into two forms: box beam and truss. Generally, a box-shaped structure is used.

Working level

Gantry crane is also the working level of gantry crane: it reflects the working characteristics of the crane in terms of load status and utilization.

The division of the working class is determined by the utilization class U and the load state Q of the crane. They are divided into eight levels from A1 to A8. Crane working level,

That is, the working level of the metal structure is determined according to the hoisting mechanism and is divided into A1-A8 levels.

Roughly equivalent to: A1-A4-light; A5-A6-medium; A7-heavy, A8-extremely heavy.

How to choose the right gantry crane?

Under normal circumstances, the lifting capacity is less than 50t, the span is less than 35m, and there are no special requirements for use, the single main beam type should be selected. If the width of the gantry legs is required to be large, the working speed is high, or the heavy and long pieces are often lifted, the double-girder gantry crane should be selected.
