Excavator Track Shoe

Excavator track shoes are the parts of the track that dig into the earth to pull the machine along. Excavator shoes don't work for excavators alone, they are also essential parts of the undercarriage in crawler cranes and bulldozers. Excavator track cleats for large excavators are made of tough steel alloys such as 25MnB and 25CrMnB steel. Heat treatment and painting are also applied to harden the surface and make it attractive. Track shoes may also be made of rubber. Steel track shoes are assembled by welding or by fastening with screw threads.

Which is Better: 25MnB or 25CrMnB Steel Track Shoes?

Both 25MnB steel and 25CrMnB steel materials are alloys with manganese and boron. With proper heat treatment, 25CrMnB and 25MnB can satisfy the strength and mechanical requirements for triple grouser track shoes. However, the inclusion of Chromium (Cr) in the steel refines the microstructure of the material. It also boosts hardness, toughness, and strength of the steel. The toughness of 25CrMnB under impact testing at room temperature is significantly higher than that of 25MnB. That means that when the excavator is working under heavy load in poor working conditions, the 25CrMnB steel excavator grouser is a better option.

What are Some Benefits of Durable Track Shoes?

The triple grouser shoe or pad is the outermost section of the excavator's undercarriage. It works like the "wheel" of the excavator. The track shoe for an excavator is built to withstand the excavator which weighs thousands of pounds. It can also overcome the force of the soil when the excavator is running. Single grouser excavator shoes make it possible for the excavator to function properly in different working conditions. The special alloy made of steel, manganese, and boron is hardened to provide great strength and resistance to wear. Excavator grouser plates can also be cast and forged for special operations. Forged track shoes may be used in mining and special working conditions.
