Transported to the yard or behind the rear, stacking up by a container double girder bridge crane or direct loading removed, can speed up the container carrying bridge crane or other turnover. Stackable high 3 to 4 layers, 6 rows wide container yard, general use tire, it also has a rail-like. Compared with container gantry crane container straddle carrier, its height and door frame on both sides of the span are larger. In order to meet the transport needs of ports, the higher the level of this wall mount jib crane work. Lifting speed of 8 to 10 m / min; span container according to the number of rows to determine the need to cross a maximum of 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 tons
Gantry crane is a variant of Bridge crane. In the port, mainly for outdoor yard, yard goods, bulk cargo loading and unloading operations. Its metal structure shaped like a door frame, bearing girder installed under two feet directly in the ground walking on the tracks, you can have both ends of the main beam overhanging cantilever.

Shipbuilding gantry cranes
Hull assembly for berth, wall mount jib crane standing with two lifting car: There are two main hook of a run on the track on the bridge flange; another has a main hook and an auxiliary hook, flange under bridge running on the track, in order to flip and hoisting large hull blocks. Weight is generally from 100 to 1500 tons; single girder bridge cranes span of 185 meters; lifting speed of 2 to 15 m / min, and 0.1 to 0.5 m / min jog speed

Cellular Beams
Generally refers to the "isosceles triangle castellated beams", main beam end face is triangular, honeycomb holes on both sides of the oblique abdominal, upper and lower portions have a chord. Honeycomb joist and girder box beam absorbed features, compared with larger joist stiffness, small deflection, and higher reliability. However, column mounted jib crane due to the use of welded steel, the weight and the cost is slightly higher than the joist. Suitable for frequent use or lifting large venues or beam field. Because of this beam type for the patented product, foundry overhead crane thus producing fewer manufacturers

Cable cranes as lifts
In bridge engineering used in lifting machinery, depending on its construction and performance, generally can be divided into For the small light lifting equipment, bridge type crane and industrial overhead cranes, cable cranes four categories. Small light lifting equipment such as: Jacks, pneumatic hoists, electric hoists, balancing gourd (aka balance suspended), winches, etc.. Bridge type crane as beam cranes. Such as fixed jib type crane slewing cranes, single girder bridge cranes, truck cranes, tire cranes, crawler cranes.

Ordinary gantry cranes
This crane types and multi-use box truss structure, the most widely used. You can carry a variety of bulk materials into items and, from the weight of 100 tons, a span of 4 to 39 meters. Grab common with the work of a higher level single girder bridge cranes. Common gantry crane mainly refers hook, grab, electromagnetic, hoist gantry crane, but also includes shipbuilding gantry crane

usually for welding structure
General bridge crane lifting trolley generally, running mechanism, workshop crane metal structure of bridge. The crab by the hoisting mechanism, car run institutions and small frame is composed of three parts.The lifting mechanism comprises a motor, brake, reducer, drum and pulley blocks. Motor through reducer, driven rotating drum, so that the wire rope around the drum or from the roll down, semi gantry cranes to lift heavy objects. Small frame is a supporting and installation rack lifting mechanism and operation of institutions such as car parts, usually for welding structure.

by with a cart running mechanism of bridge
The bridge ends by running the device directly support the bridge type crane on the elevated track, known as the "bridge crane". grab bucket crane is general by with a cart running mechanism of bridge, equipped with several hoisting mechanism and the car run institutions lifting trolley, portal crane suppliers electrical equipment, driver cab parts. Shaped like a both ends of the support in the two overhead track parallel translation operation on Dan Kuaping bridge
