Do-It-Yourself Silo Cleaning and Bin Cleaning Equipment, A Faster, Safer Way To Unlock Bridged Material

Versatile, Strong, and Safe

This tough, portable miniaturized rock drill is the ideal silo cleaning equipment for material that tends to “arch” or “bridge” across the entire vessel.

The Arch•Master™ was designed to create flow channels (up to 152 feet or 45 meters deep) in arched or bridged material. In some cases, this may be all that is required. In other instances, the Junior 360º™ or our turnkey Big•Mole™ service may be needed to complete the Silo Cleaning or Bin Cleaning process.

The Arch•Master™ features a high torque, variable speed, hydraulic power head that can rapidly drill even the hardest material. Additionally, the Arch•Master™, which measures slightly over 7 feet, 4 inches (2.3 meters) in height, offers a double-roller chain drive, a special duty hydraulic motor for variable speed drilling, all-aluminum construction, heavy-duty 3 – 6 inch (7.6 – 15.2 centimeter) augers, and quick-connect hydraulic fittings.

Perfect for do-it-yourself cleanout projects involving bridged materials, the Arch•Master™ provides the right solution for a fast and safe return to full material flow.
