Information

Gantry crane is a variant of bridge crane, also called gantry crane. It is mainly used for loading and unloading of outdoor cargo yard, material yard and bulk cargo. Its metal structure resembles a gate-shaped frame. Two feet are installed under the main beam, and it can directly walk on the ground track. The main beam can have outriggers at both ends. Gantry cranes have the characteristics of high site utilization, large operating range, wide adaptability and strong versatility. They have been widely used in port cargo yards.

There are many types of gantry cranes, which can be divided into the following types according to their uses. The uses of each gantry crane are described in detail.

1. Ordinary gantry crane

This type of crane mostly adopts box type and truss type structure, and has the widest application. It can handle a variety of pieces and bulk materials, with a lifting capacity of less than 100 tons and a span of 4 ~ 39 meters. The working level of ordinary gantry crane with grab is higher. Ordinary gantry cranes mainly refer to hook, grab, electromagnetic, and hoist gantry cranes, as well as semi-gantry cranes.

2.Hydraulic gantry crane

It is mainly used for hoisting, opening and closing the gate, and can also be installed. It has a lifting capacity of 80 to 500 tons, a small span of 8 to 16 meters, and a low lifting speed of 1 to 5 meters per minute. Although this crane is not often transported, once it is used, it is very heavy, so it is necessary to appropriately increase the work level.

3. Shipbuilding gantry crane

It is used for assembling the hull of the berth. Two crane trolleys are always available: one has two main hooks and runs on the track of the flange on the bridge; the other has a main hook and a secondary hook. Run on tracks to flip and lift large hull sections. The lifting weight is generally 100 to 1500 tons; the span is 185 meters; the lifting speed is 2 to 15 meters / minute, and there is a jog speed of 0.1 to 0.5 meters / minute.
