The European double-girder crane adopts more advanced crane optimization design and variable frequency drive technology. The crane has the characteristics of smaller size, heavier and lighter, better unprotected performance, stable operation, accurate positioning, and higher work continuity rate. Due to the use of hardware equipment such as high-strength galvanized steel wire ropes, disc brakes, hard-tooth surface reducers, programmable rise limits, and cable-stayed wire rope guides, this kind of crane has inching functions, real-time monitoring, and prevention of electronic shaking. High-speed hover and micro-speed functions.

European bridge cranes have light weight, compact structure, and low energy consumption. A trolley and a lifting mechanism are installed on the bridge frame. The trolley can run forward and backward, the trolley operates and other mechanisms to realize the transportation of materials and objects in three-dimensional space. European-style cranes Adopting a unique design concept, it has the characteristics of small size, light weight and low wheel pressure. Compared with traditional cranes, the limit distance from the hook to the wall is smaller, the headroom is lower, and the crane can work closer to the front. The lifting height is higher, which actually increases the effective working space of the existing factory building. Since the crane has the characteristics of light weight and small wheel pressure, the new factory space can be designed to be smaller and more functional. A smaller plant means considerable savings in the initial construction investment, as well as in long-term heating, air conditioning and other maintenance costs.

Advantages of European double girder crane.

1. Reduce customer investment, make full use of on-site space, and improve production efficiency.

2. Good combination, multiple specifications and complete product series, which can meet most of the needs of customers.

3. Safe and reliable, using advanced design concepts and mature technology to ensure product design.

4. Reliable performance, low failure rate, reducing use and later maintenance costs.

5. Ensure smart devices and multiple functional interfaces to make function expansion easier.

Features of main beam structure:

1. The main beam adopts a square H-shaped steel structure design, which is similar to the original simple walking vehicle and has a heavier dead weight.

2. All main welding shall be subject to non-destructive testing.

3. The steel plate material is domestic common steel.

4. Vertical rotation is subject to national standards.

5. Like traditional cranes, all steel plates have undergone shot blasting pretreatment and reached Sa2.5 level standardization.

6. Carefully inspect and clean the steel plate before welding. Welding is usually performed on an automatic welding machine.

End beam features:

1. The end beam is welded and formed by a rectangular steel pipe or steel plate. The formed end beam is positioned and processed by a CNC machine tool at one time to reach the allowable deviation range.

2. Each end beam is equipped with two-wheel rim wheels, buffers and anti-derailment protection devices.

3. The double-girder crane is equipped with a maintenance platform on the driving side of the cart along the direction of the main beam.

4. Use high-strength bolts to fasten the main beam and end beam to ensure the accuracy of the whole machine and the stability of operation.

In the process of using double-girder cranes, we must attach great importance to safety issues to ensure the safety of personnel and equipment. The following are safety issues that need to be paid attention to when using double-girder cranes:

 

Safety awareness of crane operators: Crane operators need to undergo special training and qualification certification, and be familiar with the working principles, operating procedures and safe operating procedures of the crane. They should have a rigorous work attitude and a high degree of safety awareness, stay focused, and not be distracted or careless to ensure the safety of operations.

 

Routine maintenance and inspection of cranes: Cranes require regular maintenance and inspections to ensure the normal operation and safety performance of each component. Crane operators should perform maintenance and inspection work in accordance with the operation manual or relevant regulations, and promptly record and report abnormal situations so that timely repairs and potential safety hazards can be eliminated.

 

Routine inspection and records of cranes: Routine inspections of cranes are required before use, including inspection and testing of various mechanisms, transmission devices, electrical equipment and their control systems. Operators should carefully check whether the screws, pins, fasteners and connections in various key parts are firm and reliable, and whether there are any abnormalities in the electrical equipment, such as disconnection, aging, corrosion, etc. After the inspection, the operator needs to record the inspection situation and confirm it with a signature.

 

The use environment and working conditions of the crane: When selecting and installing a crane, the use environment and working conditions need to be fully considered to ensure that the crane's load-bearing capacity and working range meet actual needs. At the same time, it is necessary to pay attention to the safe distance and space around the crane to avoid collision and friction with other equipment, personnel or obstacles, which may cause safety accidents.

 

Control and stability of the crane's center of gravity: During lifting operations, attention should be paid to controlling and adjusting the crane's center of gravity to ensure its stability and balance, and to avoid rollover, dumping or imbalance caused by uneven lifting of materials. Operators should promptly adjust the position and posture of the crane during the lifting process to maintain smooth and smooth operations and prevent accidents.
