Easy to install

Separate carriage assembly during installation and cantilever separately from installation, easy to install;
Embedded bearing components enable additional headroom required for installation is greatly reduced;
Bolted between the support frame assembly and the arm so that the installation work can be carried out separately, single girder crane can be very close to the arm mounted on the roof or top obstacles underneath the plant to minimize the space occupied by the top, increasing the lift hoist;
Hoist trolley run stopper bolt can be installed according to the application changing positions;
over head cranes completely sealed bottom inlet collector assembly can then be pre-installed or installed. 360 °rotating meet application environment for the hoist power supply

luffing the luffing cylinder and hydraulic system components

In order to complete construction crane functions, electric hoist manufacturers 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, over head cranes 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, slewing gear, rotary hydraulic system consisting of a full rotation

The luffing mechanism

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.

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.
