This crane uses hanging beams to lift long steel billets, plates, bars, coils, and other items, equipped with electromagnetic suction cups or clamps or special group hooks for lifting. It mainly consists of a box shaped bridge, a lifting trolley, a large vehicle operating mechanism, a driver's cab, and an electrical control system, equipped with a power-off magnetic protection system. The lifting mechanism often adopts a single motor, double reducer, and double drum arrangement, in the form of double lifting points. The arrangement of hanging beams can be divided into two types: perpendicular to the main beam or parallel to the main beam. The other forms are the same as the QD type crane.

The difference between a double trolley bridge crane and a hook bridge crane is that two trolleys are installed on the main beam, and the double trolleys can be lifted or operated separately; When lifting long items, synchronous lifting and operation can be achieved through the switch on the control panel.

The basic structure of an electromagnetic bridge crane is the same as that of a hook bridge crane, except that a DC lifting electromagnetic suction cup is hung on the hook to lift magnetic black metals and their products. The AC power is converted into DC power through a thyristor DC box installed in the driver's cab, and then the DC power is sent to the electromagnetic suction cup through a dedicated cable reel installed on the trolley.

The grab bridge crane is mainly composed of a box shaped bridge, a grab trolley, a large vehicle operating mechanism, a driver's cab, and an electrical control system. The retrieval device is a grab bucket.The grab car is equipped with a lifting mechanism and an opening and closing mechanism, and the grab is wrapped around the lifting and opening drums with four steel wire ropes. The opening and closing mechanism drives the grab bucket to close and grab materials. When the bucket mouth is closed, the lifting mechanism is immediately activated to evenly load the four steel wire ropes for lifting work. When unloading, only the opening and closing mechanism is activated, and the bucket mouth immediately opens, tilting the material.Except for the lifting mechanism, the other structural parts of this crane are basically the same as those of a hook bridge crane.

Hook bridge crane is currently a widely used lifting machinery, mainly composed of box bridge, lifting trolley, large vehicle operating mechanism, and electrical control system. The retrieval device is a hook.There are tracks laid on the main beam for the crane trolley to move laterally along the direction of the main beam. The main beam is welded to the box type end beam, and there are joints, bolts or pin shafts arranged in the middle of the end beam for the disassembly and transportation of the bridge frame.There are three operating modes: ground handle, wireless remote control, and driver's cab. The cab has two types: open and closed, with adjustable seats inside. The floor is covered with insulation pads, and the window glass is made of tempered glass. Users can configure heating and cooling air conditioning, sound systems, walkie talkies, and other items according to their requirements.The crane can be equipped with lifting devices such as motor grab buckets and electromagnetic suction cups to meet the needs of lifting various types of materials.The working level of the crane is A3 to A7, and the commonly used lifting capacity is 3 to 250 tons. Suitable for loading, unloading, and lifting operations in factories, warehouses, and freight yards with ambient temperatures ranging from -20 ℃ to 40 ℃ and relative humidity not exceeding 85%. It is prohibited to work in environments that are flammable, explosive, or filled with corrosive gases.

This crane is specifically designed for loading, unloading, and stacking 20, 40, and 45 foot international standard containers in railway freight yards. This machine is equipped with telescopic container lifting equipment for lifting containers of different specifications. The opening and closing actions, as well as the extension and retraction of the lifting equipment, are operated by the driver in the control room. At the same time, in order to adapt to different container stacking directions and container trailer walking directions, the container lifting device can be designed with a rotating mechanism, which can make the container rotate freely to improve loading and unloading efficiency.

The single main beam gantry crane is mainly composed of a gantry, a lifting trolley, a large vehicle operating mechanism, a driver's cab, and an electrical control system.The gantry is a box shaped single main beam with two legs. When the lifting capacity is less than 20t, the trolley adopts a vertical rolling wheel, and when it is greater than 20t, the trolley adopts a horizontal rolling wheel, running on one side of the main beam. The main beam adopts a single beam offset rail form, and the support legs and lower crossbeam form an L-shape. Both sides of the support legs are generally equipped with cantilevers, which have strong over span ability when lifting objects, making it easy to transport objects from the inside of the span to under the cantilevers. The small car is suspended from the side, and the lifting equipment is arranged on the side of the main beam. When the lifting weight is ≤ 20t, a vertical reverse roller two pivot form is used, and when the lifting weight is>20t, a horizontal reverse roller three pivot form is used.The operation mode adopts a closed cab with adjustable seats, insulated pads on the floor, tempered glass windows, and can be equipped with heating and cooling air conditioning, sound alarms, intercoms and other items according to user requirements.There are two forms of power supply: cable reel and high-altitude sliding line.

The structural form is basically the same as the MG type crane, with one side having support legs and running on the ground track; The other side has no supporting legs and runs on the track above the factory building.

This gantry crane is mainly used for bridge construction and has a slow working speed. It consists of a gantry, a winch trolley, a large vehicle operating mechanism, a driver's cab, and an electrical control system.The gantry is a truss structure, which has the advantages of light structure and strong wind resistance. Including main beam, upper beam, support legs, lower beam, walking trolley, and walking platform railing. The main beam adopts a triangular truss structure, with tracks laid on top for the trolley to move laterally along the direction of the main beam. The legs are available in two forms: box shaped or steel tube.The car is equipped with a winch, which is compact in size and lightweight.The operation mode adopts a closed cab with adjustable seats, insulated pads on the floor, tempered glass windows, and can be equipped with heating and cooling air conditioning, sound alarms, intercoms and other items according to user requirements.There are two forms of power supply: cable reel and high-altitude sliding line.

The double girder gantry crane is mainly composed of a gantry, a lifting trolley, a large vehicle operating mechanism, a driver's cab, and an electrical control system.The gantry is divided into box shaped structure and truss structure, with the main beam adopting a double beam offset rail form, and the support legs divided into two types: A-shaped and U-shaped according to user requirements.The operation mode adopts a closed cab with adjustable seats, insulated pads on the floor, tempered glass windows, and can be equipped with heating and cooling air conditioning, sound alarms, intercoms and other items according to user requirements.There are two forms of power supply: cable reel and high-altitude sliding line.        

The (8+8) t intelligent storage crane designed and manufactured by the company for the unmanned cold storage project of Shandong Lingdong Electronic Technology Co., Ltd.'s "Garlic to the World" industrial park is the first automated storage crane applied to agriculture in China. The crane has the characteristics of large span, long running distance, high lifting height, fast running speed, stable and wave free operation, multiple positioning points, and high accuracy.Compared to traditional warehousing, labor efficiency has increased by 100 times, land utilization rate has increased by 10 times, and comprehensive operating costs have been reduced by 60%.

This model of crane is a specialized gantry crane developed by our company based on the requirements and process conditions of subway construction, combined with a general gantry crane. It is specifically designed for flipping and pouring mud and lifting pipe segments during subway construction.The crane consists of a gantry, a trolley (equipped with a lifting mechanism, trolley running mechanism, and hydraulic flipping mechanism), a large trolley running mechanism, a driver's cab, and electrical equipment.According to the different directions of soil dumping, the leg structure can be divided into two forms: A-type and U-shaped.The large vehicle operating mechanism adopts an 8-wheel 4-drive form and is equipped with a windproof rail clamp. When the crane is working normally, the clamp of the rail clamp leaves the track. When the crane stops working, the operator lowers the clamp to clamp the track and prevent the crane from sliding.The lifting mechanism uses a hanging beam as a lifting device, and there is a freely rotating hook in the middle of the hanging beam for lifting pipe segments and other materials.The car is equipped with a hydraulic flipping mechanism, which consists of a hydraulic workstation and a flipping hook. Before the hanging beam lifts the slag hopper, the driver controls the hydraulic flipping mechanism to move the slag hook back to a specific position by the hydraulic cylinder, and then the slag hopper rises above the slag hook. The driver controls the slag hook to move forward to below the slag hopper, and the slag hopper descends. The eccentric flipping shafts on both sides fall on the slag hook and continue to descend. The slag hopper uses its own weight eccentricity to start flipping and complete the tilting work.In order to meet the characteristics of short construction period and frequent site changes in subway construction, our company has specifically added a variable span function on the main beam, so that the span can change accordingly after the construction site is changed.At the same time, a turning dump truck was developed to adjust the dumping direction according to the position of the slag outlet. By using this small car, the construction party can equip a crane to achieve soil lifting and tipping in different slag removal directions.
