Container spreaders are divided into fixed container spreader, combined container spreader and telescopic container spreader.
1.Fixed container spreader
Special spreader for lifting 20ft containers, or special spreaders for lifting 40ft containers. Directly suspended on the hoisting wire rope, the hydraulic device is installed on the spreader, and the twistlock is rotated by the twist lock mechanism, and the corner fittings of the container are connected or loosened.
The structure is simple, light weight, only suitable for lifting containers of a certain size, and the spreader must be replaced for containers of different sizes.
2.Combined Spreader (Lifting Beam)
The specially made spreader beam is suspended on the lifting wire rope, when lifting 20ft containers, the 20ft special spreader is connected to the spreader beam, when lifting 40ft containers, the 40ft special spreader is connected to the spreader beam, and the hydraulic device is installed on the 20ft or 40ft special spreader respectively.
This kind of spreader is easier to replace than the direct lifting spreader, but it is heavier.
3.Combined spreader
The basic spreader of combined spreader is 20ft container special spreader, which can lift 20ft container, and the hydraulic device is installed on the basic spreader.
When it is necessary to lift 40ft containers, the corner fittings of the 40ft container spreader (the same as the container corner fittings) are connected with the rotary lock of the 20ft container spreader. the rotary locking mechanism of the 40ft container spreader is driven by the hydraulic device mounted on the 20ft container spreader.
4.Telescopic container spreader
In order to adapt to the different size requirements of the container, can be a kind of spreader for long and short expansion and contraction.
Short transformation time (about 20s), self-importance, wide range of uses.
Is currently the most widely used container crane spreader.
MH type electric hoist gantry crane is used together with CD MD model electric hoists.
L Type electric hoist gantry crane match with CD1/ MD1, HC type Electric Wire rope hoist, to lifting and transporting the heavy materials, mainly use indoors and outdoors.
BMH Type Semi Gantry Crane is a bridge-type crane whose bridge is supported on the ground track through outriggers on both sides.
A-type Double Beam Hook Gantry Crane, It is mainly composed of a gantry (main beam, outriggers, lower beam, etc.), a lifting mechanism, a running mechanism and an electronic control part.
The rail-mounted container gantry crane (English abbreviation RMG) is one of the special machines for container yards.
MZ Type Double-beam Grab Gantry Crane are mainly used in conjunction with bridge cranes, port cranes, and winches. They are widely used in ports, power plants, docks, chemical industries, etc. to grab various types of loose accumulations, such as ore, coal, slag, etc.
Winch Gantry Crane are used in open warehouses, windy areas, material stocks area, bridge building, concrete industry, cement plant, granite industry, construction industry, engineering industry, port, transportation, construction, dockyard, and other building sites for lifting and loading unloading objects.
U Type Subway Turn Slag Hook Gantry Crane also known as subway slag flipping machine, slag flipping gantry crane, slag flipping gantry crane, etc., is a specialized gantry crane used for excavation in subway and tunnel construction projects.
