1. Ordinary gantry cranes
This kind of gantry cranes usually uses container crane types and truss structure, the most widely used. It can carry a variety of items and bulk materials into, from the weight of 100 tons, the span of 4 to 39 meters. Common gantry with the work of a higher level mainly refers hook, grab, electromagnetic, hoist gantry crane, but also includes semi-gantry crane.
2. Station gantry cranes
Mainly used for lifting and hoisting the dame gate, it can be doing installed job. Lifting capacity of 80 to 500 tons, the span is small--8 to 16 m; lower lifting speed of 1 to 5 m / min. This crane lifting is not frequently, but once the work is very heavy use, so to appropriately raise the working level.
3. Shipbuilding gantry crane
For berth assembled hull, standing with two lifting car: there are two main hook of a run on the track on the bridge flange; another has a primary and a secondary hook, flange under bridge running on the track, so flip and lifting large hull segments. Weight is generally from 100 to 1500 tons; span of 185 meters; hoisting speed of 2 to 15 m / min, and 0.1 to 0.5 m / min jog speed.
4. The container gantry crane
Used in the container terminal ports. Trailers will carrying containers unloaded from ships Transported to the yard or behind the back, stacking up by the container gantry crane or transported direct loading, carrying containers can accelerate the turnaround bridge or other cranes. It can be stacked three to four layers, wide to 6 rows of container yard, usually with a tire, but also useful rail style. The height and span both sides of the door of Container gantry cranes are larger compared to container straddle. In order to meet the transport needs of ports, higher the level of this crane work. Lifting speed of 8 to 10 m / min; span based on the number of containers needed across the row to determine the maximum is about 60 m. Corresponding to 20 feet, 30 feet, 40 feet long containers’ lifting capacity ability were about 20 tons, 25 tons and 30 tons.
