MOOSE® Scabbling Robot

Fully Automated, Dustless Concrete Floor Decontamination

(PDF version)

Pentek’s remotely operated MOOSE® is designed to scarify large concrete floors and slabs in environments which require stringent control of airborne contamination and debris while providing exceptional production rates. Applications include the safe and efficient collection of radioactive materials, PCB’s, chemical residues, heavy metals, and other hazardous material from manufacturing and utility facilities, military bases, and environmental restoration sites.

The MOOSE® scabbler utilizes a highly effective, single-step floor scarification process with integral vacuum control; essentially 100% of the airborne particulate and over 99.5% of heavier solids are captured at the cutting tool surface. This high level of performance prevents cross-contamination and eliminates the need for local containment and respiratory protection during operations, thus earning the MOOSE® a reputation for cleanliness and contamination control at facilities throughout the world…even in radiologically contaminated nuclear power plant environments!

The MOOSE® physically removes protective coatings, laitance, and concrete substrate to the depth of clean, uncontaminated concrete in increments of 1/16 to 3/16-inch (1.6 to 5mm). Even tough epoxy and urethane coatings can also be stripped in 18 inch (450mm) passes. The scarification technique leaves floors clean, with a uniformly keyed surface texture, ready to receive new protective coatings and overlayments.

Three integral sub-systems comprise the MOOSE® scabbler: the scabbling head assembly, the on-board HEPA vacuum system, and the six-wheeled chassis. The scabbling head houses seven independent reciprocating tungsten carbide-tipped bits. The bits pulverize the surface by delivering 1,200 hammer impacts per minute through pistons driven by compressed air.

The mechanical process is completely dry and produces the minimum amount of waste. Manufactured with high quality materials and strict attention to detail, the MOOSE® is reliable and easily decontaminated. Dust and debris are captured by the high performance, two-stage positive filtration HEPA vacuum system that deposits the waste directly into an on-board 23-gallon (87 liter) waste drum. First state efficiency is 99.5% at 1 micron; second stage HEPA efficiency is 99.97% at 0.3 microns. First stage filters are continuously and automatically cleaned by reverse-flow pulses of high pressure air, resulting in extended filter life of up to one year. The system also features an automatic full-drum alarm and a patented dustless drum exchange feature that completely eliminates operator exposure to hazardous materials.

The six-wheeled chassis is powered by dual DC motors. Independent skid steering allows the MOOSE® to pirouette 360 degrees about its geometric center. The scabbling head and chassis assemblies are designed to isolate the vibrations generated by the scabbling head, allowing the operator to maintain positive control over the direction and the depth of cut during aggressive scabbling operations.

The MOOSE® is capable of scabbling to within 6 inches (150mm) of walls and other obstructions, and can easily fit through a standard doorway. Tool ports provide direct interface to Pentek’s smaller, manually operated scarifiers: the SQUIRREL®-III floor scabbler and the Corner-Cutter® needle gun. These smaller tools are designed to scabble tight areas which cannot be easily accessed by the MOOSE®.
