Electromagnetic Overhead Crane - Henan Seven Industry Co., Ltd

Electromagnetic Overhead Crane Introduction

Electromagnetic Overhead Crane is an electric lifting equipment, mainly used for lifting metal loads. It is widely used in metallurgical plants or outdoor working environments, and is particularly suitable for loading and unloading and transporting electromagnetic ferrous metal materials such as ingots, steel and pig iron. The crane is equipped with a detachable electromagnetic plate. The lifting capacity includes the weight of the electromagnetic plate. It has main components such as a box-shaped bridge, a trolley running mechanism, a trolley, electrical equipment and an electromagnetic plate. The operation is carried out through the cab, and a rainproof device is required when used outdoors. The electromagnet is its core component, which absorbs metal objects by powering on and safely transports them to the designated location.

Advantages:
1. Powerful lifting capacity: Compared with other cranes, Electromagnetic Overhead Crane can provide higher lifting capacity and adapt to various heavy-duty operations.
2. Diversified structures: The structural forms are diverse, which can meet the needs of different customers, adapt to complex working environments and specific operating requirements.
3. Low damage rate: The electromagnetic suction cup can be easily adsorbed on smooth surfaces, reducing the risk of hook damage, thereby reducing maintenance costs.
4. Safe and reliable: Electromagnets are used as lifting tools, and the strong magnetic force ensures the stability of objects and prevents personal and property losses caused by falling. In addition, it is equipped with an automatic protection system that can cut off the power supply under abnormal circumstances to ensure the safety of operators.
5. Flexible and efficient: The design is lightweight, with the characteristics of small dead weight and flexible use. It can quickly adjust the position and direction, is suitable for operation in narrow spaces, and significantly improves work efficiency. At the same time, quick start and stop reduce waiting time and improve production efficiency.
6. Easy to operate: The wireless control system is adopted, which is convenient and fast to operate. All lifting, lowering and moving operations can be completed by remote control without manual climbing.
7. Energy saving and environmental protection: Using electromagnets to lift objects is more energy-saving than other cranes, reduces the emission of smoke and harmful gases, and meets environmental protection requirements.

Classification:
1.Parallel hanging beam: The hanging beam is parallel to the main beam, suitable for specific lifting operations.
2.Vertical hanging beam: The hanging beam is perpendicular to the main beam, providing different operating angles and flexibility.
3.Upper rotating beam crane: Designed with upper rotation function, it can achieve more flexible operation during lifting.
4.Lower rotating beam crane: With the characteristics of lower rotation, it is suitable for places where low-height operation is required.

Application areas:
1. Industry applicability: Electromagnetic Overhead Crane is used in conjunction with various lifting machinery and is widely used in industries such as steel mills, foundries, scrap steel processing plants, machining workshops, steel storage and ports.
2. Material handling: Mainly used for lifting and transporting metal materials such as cast iron ingots, steel balls, pig iron blocks and processing chips.
3. Electromagnetic crane function: Suitable for indoor and outdoor loading and unloading and transportation, specializing in handling steel ingots, steel sections, iron, scrap iron and other ferrous metal products.
4. Magnetic beam design: With electromagnetic suction cups as the main lifting tool, the direction of the lifting beam can be parallel or perpendicular to the main beam, suitable for handling long goods, including steel plates, profiles, bars, pipes, wires and coils, etc.

Design Scheme

SEVENCRANE stands for first-rate service, cost-effective, high quality.

The main beam and end beam are connected by high-strength bolts to ensure the accuracy and smooth operation of the whole machine.

A variable structure control scheme, a variable structure controller combined with a state feedback control scheme and an integrated control scheme are proposed to control the bridge crane.

We have a professional team of engineers to design and develop cranes, and have a complete technical system to analyze crane design drawings.

Our bridge crane component design and structure standards are certified according to DIN15018, BLATT2 and the steel structure welding standards are in accordance with DIN18800, BLATT7.

Equipped with a double-speed lifting mechanism, the running mechanisms of large and small vehicles all adopt frequency conversion stepless speed regulation.

All the plates are automatically cut by CNC cutting machine, and the camber of the main beam is preset to avoid the problem of deflection of the camber of the traditional fire-baked main beam.

The steel surface is treated with shot blasting and sand blasting to improve the adhesion of the paint and prevent the paint from peeling off, ensuring the long-term beauty of the whole machine.

Technology

The main welding seam adopts submerged arc automatic welding, non-destructive flaw detection, and the shape is beautiful to ensure the welding quality.

End beam material: high quality alloy steel Q345B.

The end beam is welded and formed by rectangular steel pipe or steel plate, and the formed end beam is positioned and processed on a CNC boring and milling machine at one time to ensure dimensional accuracy and fit tolerance.

The lifting trolley has a modular design, and the working level is FEM M4-M6. The entire lifting trolley has a compact structure, low headroom and light weight.

Production

SEVENCRANE stands for first-rate service, cost-effective, high quality.

The main girder of the crane is welded by steel plates, and the steel plate materials meet the international crane production standards. The main steel structure materials we use are not lower than Q235B, and the materials used have material reports and corresponding qualification certificates.

There are buffer blocks at both ends of the end beam to reduce the impact force of the collision and reduce the impact inertia. The beam body of the whole machine adopts shot blasting and painting process according to the world standard.

The running track of the trolley is made of square steel to increase the effective contact area of the wheel tread and reduce the weight of the track. The material of the square steel track is Q345B.

The operation room is operated by a linkage table, and is equipped with a remote control at the same time. Through the switch, it can be operated by remote control or switched between operations during operation. Lighting and seats are installed indoors, and the entrance of the operating room is end-entry, which conforms to European and international standards.

Our crane design concept is an extension of the European concept, and we have summarized our unique production technology and solutions through long-term in-depth research and application practice.

MAINTENANCE AND SECURITY

All operators in our production workshop must hold legal operating certificates.

The cranes we produce are equipped with a safety monitoring system, which is professionally developed by the company in accordance with FEM/DIN/ISO/GB related standards, and is used for crane operation data recording, safety protection, and electronic instruments for status display.

The safety monitoring system has real-time protection functions for more than 30 working conditions such as operating failures, safety hazards and illegal operations, preventing the crane from operating in potentially dangerous situations and ensuring the safety of personnel and equipment.

Schneider TE is a vector frequency conversion control system specially developed for European crane components.

There is shock-absorbing plastic raw material derived wedges at both ends of the crane landing gear.

Overload protection, residual current relay, PTC thermistor, crash sensor, emergency stop button, sound/light warning and warning siren are standard protection units for all our overhead cranes.

At the time of delivery, we will provide customers with crane safety operation manuals and maintenance manuals. If the customer needs it, we will also send safety engineers to the site to know the customer's safe installation.
