Single Girder %&&&&&%

Single girder overhead crane is one kind of light duty and small hoisting machinery. It will improve the effectiveness of your production plant in a very simple way: by maximizing your space.

You can utilize every square inch of your floor space.

Single girder overhead crane is designed on the basis of LD type hoist crane, characterized by the features of reasonable structure and strong rigidity.
CD1 and MD1 hoists are used together with this type of crane, a light duty one.
Lifting capacity ranges from 1ton to 20 ton, with its span from 7.5 to31.5m, work duty from A3 to A5, work temperature from -25 degree to 40 degree.
It must be handled in a medium without such hazards as combustion, explosion, and erosion
It is prohibited to be used in the combustible, explosive and corrosive environment!

Single girder overhead crane main types

Single girder bridge crane mainly has three types, customers can choose according to different needs of different types of crane.

The crane girder is of welded girder construction. This result in lower dead weight with a high degree of vertical and horizontal rigidity and small wheel loads being transmitted to the crane runway.

Control method: Pendent line with press button or remote control or both

Painting: Primer and finishing paint

Color: According to your demand

Average thickness: About 100 microns

Rain cover for outside hoist, driving units, electrical cubicle.
Warning indicator: flashing lights and warning sound.
Wireless infra-detector for anti-collusion

Single girder overhead crane main parts

Single Girder Overhead Crane Parts

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.
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).
Bridge Girder(s) – The principal horizontal beam of the crane bridge which supports the trolley and is supported by the end trucks.
Runway – The rails, beams, brackets and framework on which the crane operates.
Runway Rail – The rail supported by the runway beams on which the crane travels.
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.
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.
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.

Single girder overhead crane Packing

Electric parts are packed by high quality plywood crate to reduce distortion in conveying;
Main beams, end beams and electric hoist or winch are packed by plastic woven cloth. It can reduce abrasion when transport.

Single Girder Overhead Crane Packing

Single girder overhead crane Delivery

If the size of whole crane are suitable for container ship, usually by container;
If the size is too big, usually by bulk ship or by container after truncation;
Transport ways are based on reducing cost for you and keep the crane in good condition.
