The crane wheel is the crane's walking device. It has three types of duel edge (SL), single edge (DL) and none edge (WL). The production process includes casting, free forging and die forging. Among them, the die forging crane wheel is the most cost-effective. The casting wheel has a low price but a short life. The free forging wheel has high cost and low efficiency. The die forging wheel has low cost, high efficiency and long service life and is widely used in port cranes and bridge gantry cranes.
Our company adopts the self-developed "die forging crane wheel (fire) one-step forming" process technology. That is to say, the blank realizes die forging forming, rolling and punching of the wheel groove in one heating state, thereby improving the production efficiency; by using the rim extrusion process, the hardening effect of the wheel tread surface and the product life are improved.
At present, our company's die forging crane wheels are mainly supplied for large-scale equipment manufacturing enterprises such as Sany Heavy Industry, XCMG, Yutong Heavy Industry and Zoomlion.
