Performance characteristics of wheel set of European single beam crane

Compared with the traditional single beam crane, the main difference of the European single beam crane is that it adopts high-quality parts, and the crane wheel group is the key component of such parts.

The wheel set of European single beam crane has the characteristics of light weight, small volume and convenient installation. It is mainly composed of four parts: wheel axle, wheel plate, bearing box and bearing. It is directly matched with the three in one reducer without coupling connection. Therefore, this kind of wheel has compact structure, high assembly accuracy, stable operation and low noise.

The wheel material of this crane is high-strength 42CrMo forging, which is interference fit with the wheel shaft and connected by flat key. The wheel plate is modulated and the heat treatment hardness reaches hb300-hb380. The wheel shaft is made of 42CrMo, Quenched and tempered after rough machining, and the heat treatment hardness is hb300. The bearing box is made of cast steel. Because the bearing box is connected with the crane by bolts, the crane end beam is generally processed by high-precision boring machine with high assembly accuracy. The bearings are all self-aligning roller bearings with long service life and reliable quality.

The European single beam crane produced by Dongqi cần cẩu manufacturer adopts this kind of wheel group, and the user feedback is very good.
