European Standard Portable Overhead Crane

European Standard Portable Overhead Crane is the new type of overhead crane, we provide not only single girder bridge crane but also double beam bridge crane. The European overhead crane also be called bridge cranes and eot cranes, which are cranes with a hoist or winch traveling along the bridge between parallel runways. Our single beam traveling bridge crane are designed to meet the medium to heavy industrial lifting requirements, covering all parts of the manufacturing process.

Sketch

1. Main beam - The main traveling structure of the crane which spans the width of the bay and travels in a direction parallel to the runway. The bridge consists of two end trucks and one or two bridge girders depending on the equipment type. The bridge also supports the trolley and hoisting mechanism for up and down lifting of load.

2. End trucks - Located on either side of the bridge, the end trucks house the wheels on which the entire crane travels. It is an assembly consisting of structural members, wheels, bearings, axles, etc., which supports the bridge girder(s) or the trolley cross member(s).

3. Bridge Girder(s) - The principal horizontal beam of the crane bridge which supports the trolley and is supported by the end trucks.

4. Runway - The rails, beams, brackets and framework on which the crane operates.

5. Runway Rail - The rail supported by the runway beams on which the crane travels.

6. Hoist - The hoist mechanism is a unit consisting of a motor drive, coupling, brakes, gearing, drum, ropes, and load block designed to raise, hold and lower the maximum rated load. Hoist mechanism is mounted to the trolley.

7. Trolley - The unit carrying the hoisting mechanism which travels on the bridge rails in a direction at right angles to the crane runway. Trolley frame is the basic structure of the trolley on which are mounted the hoisting and traversing mechanisms.

8. Bumper (Buffer) - An energy absorbing device for reducing impact when a moving crane or trolley reaches the end of its permitted travel, or when two moving cranes or trolleys come into contact. This device may be attached to the bridge, trolley or runway stop.

Packing and delivery

1.Electric parts are packed by high quality plywood crate, to reduce distortion in conveying. 

2. Main beams, end beams and trolley/winch are packed by plastic woven cloth. It can reduce abrasion during the transportation. 

3. If the size are suitable for container ship, usually by container; if not, usually by bulk ship or by container after truncation
