The redesigned SPT Analyzer has new features for faster analysis of standard penetration tests in concrete. The analyzer’s main unit is able to process sensor information from the probe during setup, saving calibration time. The unit’s touchscreen interface supports multitouch gestures and has selectable color schemes for better visibility outdoors. Pile Dynamics; www.pile.com
UPDATED PAVER: Auto-Adjustable Compaction
Caterpillar’s B-Series Tandem Vibratory Rollers include three models, ranging in operating weights from 12 to 14 metric tons. The rollers feature auto-adjustable compaction on both the front and rear drums. In seconds, this feature can adjust through the drum’s full range of amplitudes, reducing the chance of overcompaction or de-coupling. A screen in the operator’s station shows pass and temperature mapping. The Tier 4 Final engine features an automatic eco mode to save fuel. Caterpillar; www.cat.com
PIPE BEVELER: Single Operator Can Prep Large Pipe for Welding
The Terminator Millhog Pipe-Beveling Tool allows a single worker to perform welding-end prep work on large-diameter pipes. The tool can work on pipe from an 85⁄8-in. inner diameter up to a 36-in. outer diameter. The Terminator Millhog can bevel, face and bore simultaneously. During operation, the tool clamps to the inner wall of the pipe and has a tracker to compensate for variations in wall thickness. It comes with titanium-nitride-coated tool bits, which can be selected by the user to suit the job. A 5-hp motor is standard, with an optional hydraulic motor that does not require cutting fluids.
