Feature Description:

1.     QD model 500/100-550/100t overhead crane with hook is mainly composed of bridge, running gear of crane, trolley and electric device, etc. It is divided into two working classed: A5 and A8 according to the use grade and load-up condition.
2.     There are three kinds of method for entering the platform of cab: from the side, from the end and from the top. The figure is the side entrance; arrowhead A shows the end entrance; the top entrance is at the place is no door.
3.     The figure shows that the cab is mounted at the left end.
4.     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.
5.     Operation of the crane shall be finished in the cab completely.
6.     H0 is the increased height of buffer of the crane, H0≤250

Single & Double Girder Overhead Crane:

Overhead Cranes can also be referred to as Bridge Cranes.

Using pre-engineered and bespoke components based on modular designs, we are able to deliver a large range of highly reliable cranes with capacities from 1 ton up to 550 ton SWL with single girder, double girder or underhung structures.

Our standard crane range uses our super efficient chain hoist, highly advanced wire rope hoist or built-up open winch hoist with competitive prices and very quick delivery times.
Santocranes' hoists and cranes have developed a strong reputation for reliability and endurance with an unparalleled record in a vast range of applications and environments worldwide.

Single and double girder top running crane:

• A single girder crane has only one bridge beam, and the hoist trolley operates or travels on the lower flange of the bridge girder.


• A double girder crane will have two bridge beams, and the hoist trolley travels on rails, usually attached to the tops of the crane girder.

Compared with double girder electric hoist, the open winch trolley hoist and crane driving system is designed to be much stronger and faster. Open winch model double girder overhead bridge crane is a better choice for heavy duty working condition.

• Third times Primary Paint for whole structure


• Final Paint the color is depend on cutomer's requirement

Traditional Chinese type overhead Crane Design

Strong and durable steel material adapted make the whole crane more safety.

Cheaper price while the quality from us are top of line, because we are professional.

Euro-style single and double girder overhead crane

Compact design especially for low clearance workshop. Light deadweight help lower the total cost for construction.

Meanwhile, the price is also more affortable than other supplier.

There is some interconnectedness between different standards, We always insist that the crane & crane components design and manufacturing meet or exceed the latest international standards such as ISO, FEM, DIN, HMI, ASME and CMAA.
