Double girder overhead crane is a widely used lifting machinery, mainly composed of box-shaped bridge, crane trolley, trolley running mechanism, electrical control system, etc., and the hook is the lifting device.
Double girder eot crane is equipped with a support for the crane to move horizontally. The main beam is welded to the box-shaped end beam, and a joint is provided in the middle of the end beam. The joint is fastened with bolts to facilitate the segmented transportation of the bridge. The platform is used to place the trolley running mechanism, electrical equipment and maintenance.
Double girder overhead crane has three operation modes: ground control, wireless remote control, and driver’s cab. The driver’s cab is open and closed. The driver’s cab is equipped with adjustable seats, ground insulation pads, tempered glass windows, fire extinguishers, electric fans, and can be equipped with air conditioners, sound and light alarms, intercoms and other auxiliary equipment according to user requirements.
30 ton double girder overhead crane can be equipped with electric grabs, electromagnetic suckers and other lifting devices to meet the requirements of material types.
The bridge adopts box beams and is welded by automatic submerged arc welding.
The trolley adopts a new type of conductive device of I-beam rail cable, which is reliable.
The lifting mechanism can also be equipped with another set of devices as needed to improve reliability.
The parts are standardized, serialized and universal.
The control room has a wide field of vision, all mechanisms are operated in the control room, and the operation is flexible.
The double girder eot crane is classified into A3-A7, and the common lifting capacity is 3-250t. It is suitable for factories, warehouses, and cargo yards with an ambient temperature of -10-40℃ and a relative humidity of no more than 85%. It is prohibited to work in flammable, explosive and corrosive gas environments.
The 30 ton double girder overhead crane is suitable for smelting workshops of electrolytic non-ferrous metal materials such as aluminum and magnesium. In order to prevent the current on the live equipment from being transmitted to the crane through the hoisted parts during work, endangering the driver’s life and equipment, several insulating devices are set at the corresponding parts of the crane. This double girder overhead crane is a heavy-duty system. To ensure lifting, the main lifting mechanism uses double brakes, and all mechanisms are operated in the driver’s cab.
