The luffing mechanism, scrap handling crane the winch gear, hoisting rope, lifting hydraulic system consisting of hoisting mechanism, and a power telescopic main boom, jib, turntable, counterweight, the car working chamber, electric control or lighting systems. Difference crawler electric gantry crane and mobile cranes that seat for a motor chassis and planetary gear-driven crawler chassis as well as a truss boom boom.
Metal skeleton structure is a crane, the main bearing member such as bridge, boom and mast may be a box structure or truss structures, but also for the web structure, and some can be used as the supporting steel beams.

It works by the above frame work of agencies in Figure One
Tower crane base support is generally fixed on the ground, industrial overhead cranes in part by job rotation, luffing, lifting bodies, the difference is the use of running luffing tower crane trolley, carrying part of the tower, boom, shipbuilding gantry crane balance arm, tower caps, balancing weight and other components.It works by the above frame work of agencies in Figure One.

will and hydraulic energy into mechanical energy
One can see from the chart, the engine power through the gearbox PTO outlet pass to get off the multi-joint pump, double girder bridge crane the mechanical energy into hydraulic energy and hydraulic energy transfer through multiple distribution valve to each cylinder, each motor, portal crane manufacturer will and hydraulic energy into mechanical energy

complete construction crane functions
In order to complete construction crane functions, column mounted jib cranes construction cranes are generally supported by the base portion and the upper portion of vehicle operation, etc., for mobile cranes, the base includes a support portion of the chassis on the road and other load-bearing structure and chassis legs, while the chassis also powered through the center of the rotary body to work on the car; the car operation portion includes a turning mechanism on the car to achieve a 360-degree rotating support, foundry cranes slewing gear, rotary hydraulic system consisting of a full rotation

General overhead cranes generally consists of lifting trolley
General overhead cranes generally consists of lifting trolley, scrap handling crane, bridge metal structures. Lifting the car and consists of hoisting mechanism, trolley traveling agencies and small frame three parts.ship gantry crane forming a rectangle the scope of work, you can take full advantage of the space below the lifting bridge materials, not hampered by ground equipment.

single girder crane
double girder overhead crane manufacturers can't change "hard to hard" cooperate relationship, under the force combination, still can cause wear again. The latest maintenance method with high polymer composite material is given priority to, more have the ka wah technology products, single girder crane and is widely applied it has strong adhesion, excellent comprehensive properties such as compressive strength.
