40Ton Span 22.5M European Style Double Girder Overhead Crane End Carriage

40Ton Span 22.5M European Style Double Girder Overhead Crane End Carriage

Technical Parameters:

1. Lightweight and compact design (core European features):

High-strength materials: A large amount of high-strength steel is used, which significantly reduces the weight of the end beam itself while ensuring the load-bearing capacity and rigidity.

Optimized structure: The end beam structure is optimized by finite element analysis, and a reasonable box beam or combined beam structure is adopted to avoid redundant materials and achieve a compact volume.

Small wheel diameter: European designs tend to use wheels with relatively small diameters (but still meet the wheel pressure requirements), which reduces the overall height and weight of the end beam.

Compact drive unit: A highly integrated "three-in-one" drive mechanism is adopted, which is compact.

2. Highly integrated "three-in-one" drive mechanism:

Integrated design: The drive motor, brake and reducer are highly integrated into a compact drive unit module. This is one of the most iconic features of the European end beam.

Advantages:

Easy installation and maintenance: Overall disassembly and assembly, quick on-site installation and commissioning, and convenient later maintenance and replacement.

Space saving: Greatly reduces the space occupied by the drive part in the end beam.

Reliable performance: The mature three-in-one unit produced by professional manufacturers has good matching and runs smoothly and reliably.

Reduced components: The traditional open gears, long drive shafts, couplings and other intermediate transmission links are eliminated, reducing the failure points.

3. Optimized wheel arrangement and load:

Double-wheel or four-wheel design: For larger tonnages such as 40 tons, the end beam usually adopts a double-flange wheel x 2 sets (a total of 4 wheels) design, or even an 8-wheel design (two balancing trolleys on each side, two wheels on each trolley). This can effectively disperse the wheel pressure, adapt to larger tonnage loads, reduce the pressure on the track, and reduce the cost requirements of the track and foundation.

High-strength wheels and bearings: The wheels are made of high-quality cast steel or forged steel, and the surface is quenched to improve wear resistance and load-bearing capacity. Bearings usually use heavy-duty spherical roller bearings, which can withstand large loads and allow a certain amount of track installation errors.

Angular bearing box: The wheels are usually installed in angular (or square) bearing boxes, which are convenient for adjusting the horizontal and vertical deflection of the wheels, ensuring good contact between the wheels and the rails and reducing the phenomenon of gnawing the rails.

4. Strong and stable box beam structure:

The main body of the end beam is usually a closed box structure welded from steel plates, which has excellent bending and torsional rigidity, can effectively withstand various dynamic loads during crane operation (especially the horizontal inertia force when the trolley starts and brakes) and the torque generated by possible skew operation, ensuring the stability and operation accuracy of the whole machine.
