What models of excavators are suitable for hydraulic breakers？

2024-10-17

There are many models of excavators suitable for hydraulic breakers. Here is a classification introduction for you:

1. Small excavators (1-10 tons):

- 1-4 ton class: Usually suitable for hydraulic breakers with smaller diameter drill rods, such as 53 and 68 millimeters. Common suitable models include Kubota U15, Yanmar ViO17, etc. These small excavators generally use hydraulic breakers in small construction sites, municipal engineering, courtyard construction and other places for small-scale crushing operations, such as demolishing the foundations of small buildings and crushing small concrete pavements.

- 5-7 ton class: Can be equipped with hydraulic breakers with a drill rod diameter of 70 or 75 millimeters. Excavators like Caterpillar 305.5E2 and Komatsu PC56 are suitable for some small earthwork projects and road maintenance and other operating scenarios, and can perform medium-scale crushing work, such as crushing small rocks and demolishing small brick-concrete structures.

- 8-10 ton class: Can be equipped with hydraulic breakers with a drill rod diameter of about 85 millimeters. For example, excavators such as Hitachi ZX70 and Kobelco SK75 can perform relatively heavy crushing tasks in some small mines, quarries or larger-scale municipal projects, such as crushing larger rocks and concrete structures.

2. Medium excavators (11-30 tons):

- 11-17 ton class: Suitable for hydraulic breakers with a drill rod diameter of about 100 millimeters. For example, excavators such as Caterpillar 313D2 and Komatsu PC130 are often used in road widening and foundation construction projects in urban construction to crush harder soil and rocks, and are also suitable for auxiliary operations in some small mines.

- 18-25 ton class: Can be equipped with hydraulic breakers with a drill rod diameter of about 135 millimeters. Models like Caterpillar 320 and Komatsu PC200 are typical representatives of this class and are widely used in various construction projects, mine exploitation, and road construction scenarios, and can efficiently crush medium-hard rocks and concrete structures.

- 26-30 ton class: Suitable for hydraulic breakers with a drill rod diameter of about 150 millimeters. For example, excavators such as Volvo EC290 and Doosan DX300 play an important role in large construction projects and large-scale mine exploitation, and can handle the crushing tasks of relatively hard rocks and large concrete structures.

3. Large excavators (31 tons and above):

- 31-45 ton class: Suitable for hydraulic breakers with a drill rod diameter of about 165 millimeters. For example, large excavators such as Caterpillar 336 and Komatsu PC360 are often used in large-scale mine exploitation operations and large-scale infrastructure construction projects, and have strong crushing capabilities and high work efficiency.

- Above 45 tons: Can be equipped with larger hydraulic breakers, and the drill rod diameter can reach 175 millimeters and above. Super large excavators like Caterpillar 395 and Komatsu PC800 are mainly used in large-scale open-pit mines, large-scale water conservancy and hydropower projects and other large projects, and can perform large-scale crushing operations on hard rocks.
