double girder gantry crane design - Dongqi gantry crane
The Horizontal bridge is disposed on two legs which constitute a gantry crane.
This gantry crane is working by traveling rails on the ground, mainly used in open-air storage yard, docks, power plants, ports and railway stations and other places for cargo handling and installation operations.
Gantry crane hoisting mechanism, trolley traveling mechanism and bridge construction, are basically same with bridge crane. Because of long span, gantry crane are usually used by respective driven way to prevent the crane producing skewed running and increasing the resistance, and even accidents.
Gantry crane trolley is running on a bridge, and a lifting trolley is just like a boom-type cranes. Legs on both sides of the bridge are generally rigid legs; when span more than 30 meters, generally on one side, it is the rigid leg, while the other side is flexible leg connected through a ball joint and the bridge, the mast become statically indeterminate system under external loads to avoid outside thrust caused additional stress, it can also compensate bridge vertical temperature deformation gantry cranes wind area, to prevent falling or tipping over the line in the strong wind, and equipped with wind measurement instrument and operation interlock mechanism crane rail clamp.
Types of gantry cranes according to the gantry crane structures:
Full gantry crane design is the most popular gantry crane system, which —consisted of two legs that ride on crane rail, embedded flush with the top surface of the floor. The full gantry cranes typically run in a straight line in a designated work area. This type of gantry crane design highly utilizes the space underneath of the gantry crane girder between the legs making the scissor lifts, fork lifts, carts, and trucks or other lifting equipment cross the crane possible.
Single girder gantry crane is equipped with duel-speed electric hoist, widely used in workshop, storage, port, and hydroelectric power station and outdoor places. Gantry crane specifications:

Double girder gantry crane Double girder gantry crane is applied to the open warehouse or rail along for general handling and lifting work. Gantry crane specifications:

The semi gantry crane design refers to the gantry crane system with one leg riding on one leg running on rail on the ground and the other leg is replaced by riding on a rail on a rail supported by the building columns or a side wall of the building structure. The semi gantry crane design can save you floor space / work space.
Semi-gantry crane Semi-gantry crane is a small or middle crane, widely used for materials handling, outdoor place and warehouse for loading and unloading.

Portable gantry cranes are designed for smaller and lighter-duty material handling. The portable gantry systems run on casters or rubber wheels, which makes the gantry crane flexible and portable to move throughout a facility to handle various materials or loads.
Portable gantry crane With no loads, the portable gantry cranes can be empty and not be moved or stored anywhere throughout a workshop or workshops to providing greater space-saving and floor space flexibility. Gantry crane specifications:

Adjustable design of the gantry crane makes the lifting height and crane span can be adjustable. The adjustable gantry crane designs offering more flexibility when transporting a gantry system in and out of a facility or through different areas of a workshop
Adjustable gantry crane The adjustable gantry crane is your affordable material handling solution. 3 way adjustable gantry crane is your most convenient gantry crane. Gantry crane specifications:

Types of gantry cranes classified according the the applicaitons.
The gantry crane for general use is the most versatile gantry crane. It can carry a variety of items and bulk materials, the weight of below 100 tons, a span from 4 to 35 meters. gantry crane with grab has higher working class.
Station gantry crane is mainly used for lifting, opening and closing the shutter, but also used for installation. Lifting capacity from 80 to 500 tons, the smaller span from 8 to 16 meters; lower lifting speed from 1 to 5 m / min. This lifting crane, though not often used, but once it working, it is frequent and heavy used, so the working class should be higher.
Shipbuilding gantry crane is used for berth assembled hull, standing with two lifting trolley: one with two main hook, running on a bridge flange track; another has a primary hook and an auxiliary hook in running on the bottom flange of the rail bridge, in order to flip and lifting large hull blocks. Weight is generally from 100 to 1500 tons; span of 185 meters; lifting speed from 2 to 15 m / min, and from 0.1 to 0.5 m / min JOG speed.
Container gantry crane
Container gantry crane is used for container terminal. After the trailer carrying container wharf bridge transport container unloaded from the ship to the yard or rear, it will be stacked up directly loading or transported by the container gantry crane, which can speed up the container carrier bridge crane or other turnover. It can be stacked 3 to 4 layers high, and 6 rows of container yard wide, general use tire model, it also has a rail model. Compared with the container gantry crane container straddle carrier, its height and span both sides of the door frame are larger. In order to meet the transport needs of ports, this crane has a higher working class. Lifting speed from 8 to 10 m / min; span will be according to the number of rows to cross to decide, up to about 60 meters corresponding to 20 feet from the weight of 30 feet, 40 feet long containers were about 20 tons, 25 tons and 30 tonnes.
