Komatsu Hydraulic breaker JTHB355-5B

This hydraulic breaker supports demolition and rock breaking tasks

The Komatsu hydraulic breaker is intended for demolition and rock breaking tasks. It matches excavators in the 27 to 40 ton class. An operating weight of 2,880 kg supports stable attachment use on suitable carrier machines.

This breaker is relevant where concrete, asphalt, stone, or compact material must be broken in place. It allows the excavator to move from digging work to breaking work within the same area. That can simplify handling where several task types must be completed during one project phase.

The carrier machine size is important for attachment matching

The stated machine size gives a clear basis for initial compatibility checks. A breaker in this class is intended for excavators that can support its weight and operating demands. This matters when assessing attachment use, machine balance, and work planning on site.

For contractors managing mixed demolition or ground preparation work, correct breaker sizing affects daily machine use. It also affects how easily the excavator can be assigned to breaking tasks without changing to another carrier machine.

The attachment weight supports controlled breaking work

A weight of 2,880 kg is a key value when reviewing this breaker. It helps buyers assess transport planning, machine setup, and the practical fit with existing excavators. Weight also matters when the attachment is moved between projects or stored with other tools.

In breaking applications, attachment weight contributes to how the breaker works with the excavator arm. This is relevant when material must be broken in a defined area with repeatable machine movement and controlled tool positioning.

This breaker fits projects with repeated material reduction

A hydraulic breaker is used where material must be reduced before loading, removal, or further processing. Common tasks include demolition work, trench preparation, road work, and breaking of rock or hard surfaces. The Komatsu breaker is therefore relevant for contractors who need a dedicated breaking attachment for excavators in the 27 to 40 ton segment.
