Komatsu Demolition crusher – JRDC290-1

This demolition crusher is built for concrete reduction

The Komatsu demolition crusher is made for breaking and separating concrete with reinforcing steel. It matches carrier machines in the 24 to 35 ton class. This makes it relevant for demolition, recycling and site clearance where controlled crushing is required.

Controlled crushing is important where surrounding structures remain in place. The crusher allows material to be gripped and broken in a defined sequence. This can help operators manage fragments during dismantling of walls, slabs and foundations.

The operating figures support repeatable crushing work

A closing force of 100 tons supports the crushing process during structural demolition. The open and close cycle is 2.0 and 1.9 seconds. This timing helps maintain a steady work pattern when material must be processed continuously.

When evaluating a demolition crusher, cycle time and closing force are key operating factors. The 100 ton closing force gives a direct indication of the crushing action. The 2.0 second opening time and 1.9 second closing time describe movement speed.

Together, these figures help assess output in repetitive demolition work. They also support comparison with existing carrier machines and planned applications. This is useful when the crusher must fit established site procedures.

The attachment dimensions matter for machine matching

The attachment weighs 2,670 kg and has a length of 2,185 mm. These values matter when matching the crusher with the excavator and working envelope. They also affect transport planning, machine balance and access around structures.

The stated machine weight range provides a clear starting point for selection. Attachment choice should also consider carrier hydraulics, stability and the material handled. This helps align the tool with the work scope and machine fleet.

The tool fits demolition and recycling workflows

A demolition crusher is suited to tasks where concrete must be reduced before loading or sorting. Separation of material at the demolition stage can support cleaner handling downstream. This is relevant on urban projects, renovation work and recycling yards.

For contractors using 24 to 35 ton excavators, the tool fits common demolition workflows. It allows the carrier machine to break and process material on site. That can reduce the need for additional handling before material leaves the work area.
