The standard new generation CAT®345 GC hydraulic excavator is equipped with a 2.4 cubic rock bucket as standard, and a maximum of 2.6 cubic rock bucket is optional. The hyperbolic bucket shape improves the excavation performance while reducing the wear on the bottom, and is equipped with a clearance adjuster. The side protector can ensure durability under high friction and high impact conditions, and the reinforced penetrating bucket teeth use more wear-resistant materials and have a sharper appearance.
