120-volt, 20-amp drills offer idle RPM of up to 1,720 RPM. Meanwhile, Pentruder continues to develop its range of hi-cycle core drills. The company exhibited its new, 15-speed MDU hi-cycle core drill at the show that run on 200-220-volt and 480-volt power and have brushless motors for reduced maintenance. Diteq Corporation showcased its range of Shibuya core drills, including the pistol-grip RH-1532 handheld drill. The 15-pound unit can produce up to 2,900 RPM under load and can accommodate a 4-inch-diameter bit while remaining handheld.
Selective Demolition World of Concrete 2012 was the venue for the introduction of the new B100 demolition robot from Brokk. The new machine runs on an electric, 480-volt, three-phase motor and is capable of 360-degree rotation. The one-ton class robot has a new control unit and has been designed to increase breaker productivity by 35 percent compared to its predecessor— the B90. Husqvarna also exhibited its range of demolitions robots, highlighting new crushers attachments for all three models—The DXR 140, 250 and 310. The 29.5-horsepower DXR 310 has a reach of 18 feet and can contract to 31 inches for confined spaces.
Scanning and Detection Advancements in industry technology continue to move at a fast pace, particularly in the realm of ground penetrating radar (GPR). Geophysical Survey Sytems, Inc. (GSSI) introduced its new StructureScan Mini HR and demonstrated how the unit can detect rebar, post-tension cable and conduit up to 16 inches deep in concrete. Results are displayed on a

5.7-inch color screen and are available in 2-D or 3-D. There was also new equipment on show at the MALA Geoscience booth, the CX12 concrete inspection tool. The user interface has been redesigned to make scanning and data interpretation easier for the operator, and the CX12 features new Windows-based software. The unit also has an electro-magnetic sensor to detect live conduits. Sensors & Software unveiled the latest version of its Conquest GPR system, designed to detect and produce results faster and more accurately than its predecessors, while James Instruments displayed its new V-Meter MK IV ultrasonic pulse velocity system. This is the latest in the V-Meter series and includes new VelocilinxTM software for improved detection. There were several other CSDA members at World of Concrete with innovative products on show too. Some of these products can be found in the Industry Bits section of this magazine (page 48). World of Concrete 2012 had some encouraging signs. Attendance was higher than last year’s show and there was also an increase in exhibitor space. This annual event provides professionals from the concrete sawing and drilling industry with many opportunities to improve and expand their businesses. Decision makers from cutting and coring companies descend on the Las Vegas Convention Center each year and realize the benefits of keeping up with the latest industry developments and investing in new equipment. It is one show with many opportunities. Seizing just one of these opportunities could lead to positive changes for any contractor
