Many prospects want to know how our equipment performs on real-site jobs. Here we present a complete case from our cooperating client to show practical performance.
Japan’s aging infrastructure and frequent seismic retrofitting demand safe, efficient demolition solutions in tight urban spaces. A Tokyo-based general contractor was awarded a project to dismantle a reinforced-concrete commercial building in the Shinjuku district, where noise, vibration, and space constraints made traditional breakers impractical.
The contractor selected our concrete demolition robot – a compact tracked machine weighing 4,960 kg. This equipment arrived on-site in early 2026 and has been operating for over 4 months, completing the selective demolition of internal floors and shear walls. The demolition robot for sale proved ideal for the job, and the performance of demolition robots in construction has now been fully validated on this Japanese project.

Site Challenges for Demolition Robots in Construction in Japan
The Shinjuku demolition project presented several challenges that made equipment the preferred choice:
- Confined urban site – surrounded by active businesses and pedestrian walkways
- Strict noise and vibration limits – daytime only, with severe restrictions
- Multi-storey reinforced concrete – required selective removal without collapsing the entire structure
- Limited access – narrow alleyways prevented large excavators from entering
Traditional methods would have caused excessive disruption. The contractor needed a concrete demolition robot that could work precisely in tight spaces while minimizing environmental impact.

Installation and Setup of the Demolition Robot for Sale
Upon arrival, the equipment was unloaded and commissioned within one day. The machine was fitted with a hydraulic hammer attachment – one of the standard tools available for this machine.
The setup included:
- Wireless remote control pairing (range > 100 m)
- Hydraulic pressure adjustment to 21 MPa
- Track width set to 300 mm for stability on debris
- Optional dust suppression spray nozzle installed for indoor work
The operator quickly adapted to the machine thanks to the intuitive CAN-bus remote interface, which provides real-time feedback on hydraulic flow, engine speed, and tool status.
Operational Performance of the Remote Demolition Equipment
Over four months of daily operation (8 hours per day), the concrete demolition robot delivered outstanding results. The equipment performed the following tasks:
- Floor slab demolition – removed 200 mm thick concrete slabs on three levels
- Shear wall cutting – selectively broke non-load-bearing walls
- Column reduction – downsized columns to allow structural reinforcement
- Debris handling – used the grab tool to sort rebar from concrete
Performance metrics for the demolition robots in construction:
- Average daily output: 45 – 60 m³ of demolished concrete
- Travel speed: 2.2 km/h enabled quick repositioning between work zones
- Slewing speed up to 8 rpm for precise tool positioning
- Climbing gradient of 30° allowed navigation over rubble piles
- Zero hydraulic or engine failures – 100% uptime
The machine consumed only 37 kW at full load, significantly reducing fuel costs compared to a standard excavator.
