25Ton Span 22.5M European Style Double Girder Overhead Crane End Carriage

Technical Parameters:

1. Compact structure and lightweight design:

The optimized box beam structure (usually welded steel plates) is adopted to minimize the material usage and achieve overall lightweight while ensuring strength and rigidity.

The lightweight design reduces the load on the plant structure and reduces the cost of infrastructure construction.

2. Three-in-one drive unit:

Core features: This is the most iconic feature of the European end beam. It highly integrates the motor, brake, and reducer in a compact unit.

Advantages:

Small size and light weight: It greatly saves the internal space of the end beam and makes the overall structure more compact.

Easy installation and maintenance: As an integral module, installation, commissioning and later maintenance (such as replacement) are very convenient and fast.

High transmission efficiency and reliable performance: The integrated design reduces the transmission links, improves the transmission efficiency, and reduces the failure points. Hardened tooth surface reducers are usually used, with strong load-bearing capacity and long life.

Alignment-free: The alignment problem between the motor and the reducer, and the reducer and the wheel axle in the traditional drive mode is eliminated, and the installation accuracy requirements are relatively reduced.

3. High-strength wheels and bearings:

Wheels: Forged from high-strength alloy steel (such as 45# steel or 42CrMo), the wheel tread is quenched and has high hardness and wear resistance, and can withstand wheel pressure under a load of 25 tons. The wheel diameter is relatively large (usually above 400mm), which can effectively disperse the wheel pressure, reduce track wear, and run more smoothly.

Bearings: Use large-size, high-load-carrying spherical roller bearings. This type of bearing can automatically compensate for certain installation errors and deformations, has extremely strong load-bearing capacity and long life, and is particularly suitable for bearing heavy loads and impact loads.

4. Excellent running stability and guidance:

Usually adopts a double-flange wheel or a single-flange wheel + horizontal guide wheel design.

Double-flange wheel: Directly guided by the flank, the structure is simple and reliable.

Horizontal guide wheel: A horizontal wheel is set on the outside of the single-flange wheel, and rolling contact is made on the side of the track for guidance, which can effectively prevent rail gnawing, reduce flank wear, run more smoothly and with lower noise. This is especially important for 25 tonne loads.
