Features:
Breaking hammer:
The breaking hammer's impact frequency is 600-1100 bmp,and the impact power is 362J. This hammer is specially designed for scaling rig.
The fastest impact frequency is 1100bpm, which can remove the unstable rocks and protect the original tunnel roof from damage as much as possible.

Boom:
The boom of SRUS1 has a compact structure with more concentrated force and more stability.

Near the breaking hammer there are two helical swing cylinders, which can deliver 360° pitching and swinging without dead angle.

Dust off:
Exhaust gas purification uses water filtration to improve the working environment. Also, there is a water pump to remove the dust when scaling.

The SRUS1S Tunneling Scaler is the essential companion for every drill-and-blast tunneling project. After each blast cycle, this machine moves in to scale the freshly exposed rock surface — removing loose blocks, checking for hidden fractures, and preparing the ground for shotcrete or rock bolting.

Its compact width and tight turning radius allow operation within standard tunnel cross-sections, while the telescoping boom and tilting breaker head adapt to curved tunnel profiles with ease.

The cab's protective structure shields the operator from falling rock.

By mechanizing scaling, the SRUS1S accelerates cycle times and eliminates the most hazardous manual task in tunneling.

The SRUS1S is a multi-function construction machine that combines rock breaking, scaling, and debris clearing in one mobile platform.

The front-mounted dozer blade clears blasted material and levels the work area, while the articulated hydraulic boom with breaker attachment handles rock breaking and scaling duties.

This versatility eliminates the need for multiple machines on site, reducing equipment costs and improving job site efficiency.

The four-wheel-drive articulated carrier provides outstanding mobility across rough terrain, and the compact footprint allows operation in urban excavation sites, tunnels, and quarries alike.

With the SRUS1S, contractors get a complete breaking and scaling solution in a single economical package.
