Silo Cleaning Equipment
Junior 360º™ Whip Machine
The Junior 360º™ Series represents a technological breakthrough in equipment for the Silo Cleaning and Bin Cleaning industry. Lost storage capacity is restored quickly, safely and economically without the risk of product contamination. The fully adjustable boom and crane bearing mount allow the unit to provide complete 360° coverage of the vessel’s interior wall(s) from the initial set-up position. The unit’s modular design allows for placement in virtually any vessel regardless of shape or size.

The Junior 360º™ is available with either a hydraulically-actuated cutting head or a pneumatically-powered cutting head.
Features Common to Both Models:
- Hydraulically-assisted sectional boom provides needed flexibility to adapt to different-sized vessels
- Interchangeable blades, flails, or chain cutters engineered to safely remove a wide variety of materials
- Hose reel is independent from boom assembly for easy set-up in close quarters
- Unique 360° bearing allows for infinite positioning of the cutting head
- Positive mounting to vessel opening for safe operation (custom mounting bases available for adapting to any roof opening)
- Lightweight aluminum construction
- Sectional boom allows up to 28 ft. (8.5 m) reach for the flexibility to adapt to vessels of different dimensions
- Wire-braided hose for added strength to prevent twisting and collapsing
- Easy to transport and assemble
- Increases safety by eliminating the need to have workers enter bins or silos
Model JR360H
The Mole•Master Junior™ Model JR360H features a hydraulically-actuated cutting head. The hydraulic cutting head of the JR360H provides the operator with greater torque and a higher operating speed. The hydraulic cutting head is significantly smaller in diameter (5″ / 12.7 cm) than any head on the market, enabling it to fit into extremely small flow channels or “ratholes” which lessens time to enlarge the flow channel.
Model JR360P
The Mole•Master Junior™ Model JR360P features a pneumatically-powered cutting head with hydraulic assistance for ease of use. With an updated design, this model is ideal for applications where potential contamination of the material is an issue since hydraulic fluid is not powering the cutting head.

Arch•master™ Portable Auger System
The Arch•Master™ was designed to create flow channels (up to 150 feet or 46 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 easy-to-use Arch•Master™ is perfect for do-it-yourself maintenance crews for projects requiring a low-to-middle degree of difficulty.
