D25941K heavy-duty demolition hammer
DeWalt Industrial Power Tools
The D25941K heavy-duty demolition hammer performs concrete removal applications in demanding commercial construction environments. DeWalt equipped the D25941K with spring-loaded dust seals and a non-air pumping beat piece that keeps dust and debris out of the hammer mechanism for longer tool life. The D25941K has an electronics package that allows users to start the tool softly on contact and maintain optimum performance under load throughout demanding demolition applications. The D25941K is also engineered with a high-performance, 15-amp motor that delivers 22 foot-pounds of impact energy. To reduce vibration, DeWalt’s SHOCKS Active Vibration Control system combines shock-mounted floating handles with a counter-balance mechanism located in the barrel of the tool, decreasing user fatigue and increasing productivity. A one-step, twelve-position chisel rotation allows users to reposition a chisel’s angle using one hand. Additionally, a large rocker switch and rear rubber handles provide users with improved operation and comfort.
Four-disc floor grinder
Edco
The Edco four-disc floor grinder comes with the company’s counter-rotating disc system that enables this larger grinder to be easily operated. It glides smoothly across the floor with no torque from side to side. The unit boasts a 36-inch working width with 4 square feet of surface contact area. Another unique feature about this machine is its multi-accessory discs. These discs allow the machine to accept numerous accessories such as Dyma-Serts, Strip-Serts, grinding stones, wire brushes, scarifier assemblies and more. It is designed for production grinding, cleaning, stripping, leveling or smoothing of large surface areas. It is also designed to repair concrete surfaces, remove old coatings, prep surfaces for new overlays and take down high areas as well as texture concrete if needed. The unit is available with electric, gasoline and/or propane power options and comes standard with a 3-inch vacuum port for dry grinding and a garden hose hook-up for wet grinding to control dust.
CRT 48 series
Wacker Neuson Corp.
Wacker Neuson’s 48-inch, CRT 48 Series of ride-on trowels offers an innovative Dynamic Steering Stabilization System (DSS) that combines two patent-pending features. The first patent-pending feature is a torsion-assist steering system that reduces the amount of force needed by the operator to control the machine by 75 percent (compared to previous models). This improved steering system makes the unit easy to steer and greatly increases production by reducing operator fatigue. By nature, ride-on trowels are designed to be used for long periods of time on large concrete pours. The amount of force needed to control the unit is reduced dramatically, ergonomically designed twin-leverl controls provide excellent maneuverability, and feedback from the concrete conditions all contribute to a highly productive finishing machine. The second technical change to Wacker Neuson’s CRT 48 Series is a patent-pending steering dampener system. This system reduces the effect of stick-slip friction between the concrete surface and the trowel blades, commonly referred to as “chatter.” This “chatter” causes occasional machine vibration while troweling through the transition phase of curing concrete. The combination of the patent-pending torsion-steering-assist system and the patent-pending steering-dampener system can be found on all of Wacker Neuson’s 2008 CRT 48 trowels. Testing, analysis and customer feedback indicate that these machines are now the only mechanical-steer models in the market that do not exhibit “chatter” and virtually eliminate steering fatigue.
