QD 500/100 ~ 550/100 ton Overhead Crane With Hook

An overhead crane, commonly called a bridge crane, is a type of crane found in industrial environments. An overhead crane consists of parallel runways with a traveling bridge spanning the gap. A hoist, the lifting component of a crane, travels along the bridge. If the bridge is rigidly supported on two or more legs running on a fixed rail at ground level, the crane is called a gantry crane or a goliath crane.

Unlike mobile or construction cranes, overhead cranes are typically used for either manufacturing or maintenance applications, where efficiency or downtime are critical factors.

Overhead cranes are commonly used in the refinement of steel and other metals such as copper and aluminium. At every step of the manufacturing process, until it leaves a factory as a finished product, metal is handled by an overhead crane. Raw materials are poured into a furnace by crane, hot metal is then rolled to specific thickness and tempered or annealed, and then stored by an overhead crane for cooling, the finished coils are lifted and loaded onto trucks and trains by overhead crane, and the fabricator or stamper uses an overhead crane to handle the steel in his factory. The automobile industry uses overhead cranes to handle raw materials. Smaller workstation cranes, such as jib cranes or gantry cranes, handle lighter loads in a work area, such as CNC mill or saw.

Almost all paper mills use bridge cranes for regular maintenance needing removal of heavy press rolls and other equipment. The bridge cranes are used in the initial construction of paper machines because they make it easier to install the heavy cast iron paper drying drums and other massive equipment, some weighing as much as 70 tons.

In many instances the cost of a bridge crane can be largely offset with savings from not renting mobile cranes in the construction of a facility that uses a lot of heavy process equipment.

QD 500/100 ~ 550/100 ton overhead crane with hook is mainly composed of bridge,running gearof crane,trolley and electrical device,etc.

It is divided into four working classes: A3,A5,A6 and A7,according to the use grade and load-up condition.

There are three kinds of method for entering the platform of cab: from the side,end and the top. The figure is theside entrance,arrowhead shows the end entrance,the top entrance is at the place where no door.

The figure shows that the cab is mounted at the left end.

Safe slide wire or angle iron can be used for electric conduction of the crane, it can be either at the opposite side of the cab (same as the figure) or at the same side of the cab.

Operation of the crane shall be finished in the cab completely.
