30ton Double Girder Overhead Crane Lh Model with Electric Trolley
QD electric double-girder bridge crane with hook is the widely used hoisting machinery. It is mainly comprised of box-shape bridge, crane crab,trolley traveling mechanism and electric control system. The load handling device is the hook.
On the girder laid for crane to transversely move. The girder is weld with the box-shaped end girder. At the middle of the end girder are joints witch are fastened with bolts for fragmented transportation of bridge. The platform is used to place trolley traveling mechanism, electric equipment and used for repair.
It has three operation modes: ground handle, wireless remote control and cab. There are two kinds of two cab: open cab and closed cab, where there are adjustable seat, insulating mat on the floor,toughened glass for the window, fire extinguisher, electric fan and auxiliary equipment such as air conditioner,acoustic alarm and interphone which can be furnished as required by users.
The crane can be furnished with load handling devices such as motor grab, electromagnetic chuck to meet the requirement types of materials.
The crane, of a classification group of A3-A7, has a commonly used lifting load 3-250t, so that it is suitable to work in factories, warehouses and freight yards where the ambient temperature is -10-40 degrees centigrade and the relative humidity is not more than 85%. It is prohibited to work in the environment with inflammable, explosive and corrosive gas.
QD typr hanger bridge crane mainly consists of bridge, trolley travelling mechanism, crab and electrical appliances, and is divided into 2 working grades of A5 and A6 according to the use frequency.
This crane operation is complete in driver's chamber.
