Recently, China National Heavy Duty Truck Corporation has made a series of improvements to the crossbeams of the 60 mining trucks, and successfully developed and designed new aircraft beams.

Due to the heavy load, poor road conditions, poor use environment, and complicated frame loads, the mine car can easily cause the status of the crossbeam (commonly referred to as “airplane crossbeam”) at the balance axle when the overload is serious, and the maintenance and replacement It is very cumbersome and costly. The technical personnel of the special vehicle company after investigation and implementation, repeated research, decided to abandon the original structure, explore new ideas. Traditionally, the middle part of the common beam uses a single U-beam structure, while the new beam uses a double U-beam structure, the strength is greatly improved, and the middle beam body is changed from the curved surface to a plane, which improves the stress concentration; both sides are connected with the longitudinal beams. Thickness of plate thickness; thrust rod bracket changed from the traditional iron castings to steel, redesigned structure type, greatly increased contact area with the aircraft beam, reducing the pressure per unit area; the new beam boldly using new materials, the strength is further improved. The design of the new beam broke the traditional concept, its structure is simple and reliable, and its processability is good. The overall strength and toughness are greatly improved compared to the original and the reliability and durability of the frame of the 60 mining vehicle are improved.

304 Stainless Steel Shot

Stainlee Steel Shot is one of the most commonly used Metal Abrasive for shot blasting. And in them, 304 Stainless Steel Shot is also a very high quality one. On the one hand, it could strengthen the surface of die casting parts to make them have the ability of rust resistance. On the other hand, it could make die casting parts have a matte furface. It is widely used in foundry.

Longlived 304 Stainless Steel Shot is made from high quality 304 stainless steel wire by drawing, cutting and rounds.
