These cranes are typically double girder overhead cranes that can be customized to accommodate various lifting needs, such as using a grab bucket or a magnet for different types of materials.

QP type grab electromagnetic double-girder bridge crane has both a grab and an electromagnetic sucker. The electromagnetic sucker mainly uses the 

electromagnetic principle to transport steel objects, and the main part is a magnet. When the current is turned on, the electromagnet will firmly attract the 

steel object and lift it to the designated place. Cut off the current, the magnetism disappears, and the steel item is put down. 

The electromagnetic crane can generate a strong magnetic force, and dozens of tons of iron sheets, iron wires, iron nails, scrap iron and other iron materials 

can be easily collected and transported without packing, packing or bundling. The crane is equipped with safety protection devices and batteries, which can be

maintained for about half an hour after a power outage to avoid accidents.

The crane is also equipped with a grab, which can be used to grab scraps and other objects. Therefore, this type of crane can meet the two work occasions of 

grabbing and adsorbing steel waste, and has a wide range of applications.

Grab,Bucket,Grapple open direction is divided into parallel and vertical with main beam.The winch trolley wiht Magnet,Magnetic, Electromagnetic Chuck and 

the grab can be double or four wire rope, mechanical or electric hydraulic type according to different work duty and materials.

Main Features of QZ model overhead crane:

1.Grab electromagnetic dual-purpose bridge crane operating room is separated and closed.

2. The entrance of the control room platform of the crane is divided into three types: side surface, end surface and top surface.

3.Added height for cart bumpers. 4. Grab electromagnetic dual-purpose bridge cranes are divided into indoor and indoor types. When ordering, the technical requirements such as the maximum and minimum temperature of the working environment and the type of power supply should be indicated.

5. An overload limiter, a large-screen display and various protection devices are added, which further increases the safety during use.

Safety System

1. Overload protection in the event of overload, the hoist unit switches off and only the lowering motion is possible;

2. Long and cross travel limited by means of preliminary and final limit switches or Wireless anti-collision device;

3. Anti-falling protection for the Three-in-One electric motor of trolley and crane prevents from accidental falling;

4. All movements can be switched off by actuating the emergency-off switch at the control station via a main contact;

5. High quality long time bearing polyurethane materials buffer fixed at the end of trolley travelling and crane travelling to

prevent over traveling;

6. Safety hook latch used for avoiding the lifted material out off from the hook;

7. Audible and visual alarm device to inform the person stay near by the travelling crane;

8. Rain Cover for lifting mechanism of outdoor cranes, electric cabinet and driving mechanism;

9. Protective earth conductor is fitted as standard;

10. Voltage lower protection system;

11. Current overload protection system;

A two purpose overhead crane with both a grab and a magnet is a specialized type of crane designed for handling materials that require both grabbing and magnetic lifting capabilities.

Overhead Bridge Traveling Crane is widely used to transport, assemble, load and unload incompact goods in mine, port, factory, workshop, warehouses, and goods yard, etc.

The two-purpose overhead crane, equipped with both a grab and a magnet, is a versatile lifting solution that excels in a variety of industrial environments. Its unique design allows it to efficiently handle materials that require both mechanical gripping and magnetic lifting, making it an invaluable asset in several application scenarios.

1. Mining Operations: In mining environments, this crane can be employed to transport heavy ores and other bulk materials. The grab attachment is particularly useful for handling loose materials, allowing for precise loading and unloading into trucks or processing equipment. Simultaneously, the magnetic lifting function facilitates the handling of ferrous scrap and metal components, streamlining operations in the extraction and processing phases.

2. Ports and Shipping: At ports, the two-purpose overhead crane can significantly enhance the efficiency of cargo loading and unloading processes. The grab allows for the quick and safe handling of material like coal, sand, or agricultural products, while the magnet is ideal for lifting containerized metal goods or machinery. This dual functionality provides port operators with a flexible tool that can adapt to the varying demands of diverse cargo types.

3. Manufacturing and Assembly: Within factories, this crane can be utilized for lifting and transporting both raw materials and finished products along the production line. The grab is suitable for bulk materials and components, whereas the magnetic attachment is perfect for handling sheet metal, pipes, and other ferrous items that require secure lifting during assembly processes. Its ability to easily transition between two lifting methods optimizes workflow and increases productivity.

4. Workshops: In workshops, this crane can assist in various tasks such as loading materials onto work tables, retrieving heavy parts, and organizing tools and equipment. The grab allows technicians to handle awkwardly-shaped items safely, while the magnet simplifies the lifting of heavy metal objects, thereby improving safety and efficiency in the workspace.

5. Warehousing: For warehousing applications, the two-purpose overhead crane can facilitate the movement of goods—whether they are bulk materials or palletized items. The grab can efficiently manage loose items, while the magnet can quickly lift and relocate steel pallets or machinery, making it an essential tool for inventory management and order fulfillment.

6. Goods Yards: In goods yards, this crane is instrumental in sorting and organizing both ferrous and non-ferrous materials. The versatility in handling different types of loads minimizes the need for multiple cranes, saving both time and investment in equipment.

In summary, the two-purpose overhead crane with both a grab and a magnet serves a pivotal role in various industries, ensuring efficient material handling and enhancing operational productivity across numerous applications. Its ability to switch between grabbing and magnetic lifting makes it a multifunctional tool that meets the diverse needs of modern material management.
