Product Focus: Concrete tools and equipment

New models that help mix, lay and demolish concrete.

Tamping rammers  
Brave tamping rammers go where plate compactors can’t reach. Unlike compactors, tamping rammers use force over vibration to compact soil. Brave offers the BRPTR60H tamping rammer for smaller projects with looser soil that offers 10.7kN of impact force and a shoe size of 13.4 inches x 10.4 inches. The larger BRPTR68H tamping rammer delivers 12.8kN of impact force and has a 13.4-inch x 11.2-inch shoe size. Brave tamping rammers are perfect for compacting earth in awkward spaces such as trenches. Wheel kits are available.

Bobcat nitrogen-filled concrete hammers

Nitrogen breakers  
Bobcat Company offers a line of six new, powerful nitrogen breaker attachments covering all Bobcat compact equipment. They deliver powerful impact energy and are built to high quality standards with a simplified design that makes attachment maintenance easy. The new breakers have few internal parts, a single lower bushing and easily accessible grease ports that reduce the breaker’s maintenance requirements and makes rebuilds easier. The unique valve design of the breakers lessens hydraulic pressure fluctuation, which reduces stress on hydraulic pumps. An X-Change mounting frame allows the breakers to be used on a compact loader or a compact excavator. Nitrogen breaker tool capacity vary by model and include blunts, moils, chisels and nail points. An optional water nozzle kit for dust suppression is coming soon.

Dust collection system  
APT offers the new ADP10 dust collection system kit with a 21-foot suction hose, universal shroud connector, three dust collection bags and three bellows. This kit helps protect workers from exposure to crystalline silica on construction job sites. Using the Venturi principle, the ADP10 creates a vacuum using compressed air. Consuming 25 cfm per tool, the vacuum suction capacity of the system is more than four feet of water. The filter has the capacity of 99.58 percent filtration of exhaust air. A filter-cleaning mechanism enhances the filter life and a vacuum indicator notifies the operator of a clogged filter. At 55 pounds, it transports easily and sets up quickly. A trolley-mounted version is also available, which has the ability to store two working tools, such as a chisel or moil point and up to a 9-pound pneumatic tool.

Generac Mobile dust suppression unit

Mobile dust suppression system  
Generac Mobile’s new dust suppression systems nebulize the water, creating 5 to 150 micron diameter water particles that combines with dust particulate down to 80 microns and drags them to the ground. Traditional systems, like a water hose, produce water droplets of about 1000 microns in size, which only captures larger dust particles. Generac Mobile offers model options for jobs big and small. The DF7500 system can rotate 335 degrees, covering an area of 49,514 square feet. It has a maximum horizontal range of 131 feet and a vertical range of 52 feet. The unit has an electronic control panel with an optional remote control and comes skid-mounted, with a trailer optional. The DF2.2 portable system has a maximum horizontal range of 42 feet. All Generac Mobile dust suppression systems feature an electro-polished stainless-steel crown with nozzles and an electric engine-powered fan.

Drum cutters  
Kinshofer’s WS-Series drum cutters feature an exclusive pick angle and optimal chisel arrangement for high performance and minimal wear, making the attachments ideal for demolition, mining, tunneling and road construction. Drum cutters are a quieter alternative to hydraulic breakers, making them excellent for use in areas with noise restrictions. They also produce less vibration than breakers, so contractors can use them where there’s a risk of disturbing a nearby structure’s foundation. Kinshofer offers four chisel tips that attach to the wear pick: standard, heavy-duty, wear-protected and wood. Standard chisels are excellent for breaking asphalt, argillite and other soft to medium-hard rocks while the heavy-duty chisels power through medium-hard to very hard materials such as limestone and concrete. WS-Series drum cutters are available in seven models for 2- to 60-ton excavators. For added versatility, the attachment can be paired with Kinshofer’s NOX Tiltrotator, which enables 360-degree continuous rotation and multi-directional tilting up to 55 degrees.
