The soil conditioner reduces friction and helps to increase the advance rate of the tunnel boring machine (TBM) under challenging soil conditions. Soil conditioners help TBMs maintain face pressure during operation and lessen power consumption through torque reduction, optimize soil extraction and can decrease wear to the cutterhead and screw conveyor. The innovative technology of MasterRoc SLF 50 soil lubricating foam creates a highly stable foam with superior half-life, up to eight times the standard, making it reliable and usable for extended periods, even during planned or unplanned stoppages. C E N T E R R O C K I N C . Center Rock Inc. is a U.S.-based company that designs, manufactures, and distributes a complete line of pneumatic rock drilling tools and products. At its two state-of-the-art facilities, it manufactures and stocks products that are used by foundation drillers, construction companies, leading oil and gas drillers, quarry and mining blasthole/exploration drillers, and water well drilling contractors across the globe. Its products include a full line of air rock drilling tools and accessories including DTH hammers and bits from 3.5- to 36-in. diameter, overburden drilling systems, and LP Canister Drills from 24 to 144 in. (Standard, Reverse Circulation, HDD, Mining and Utility). Center Rock also offers mobile workshops and custom manufactured drill strings, all supported by factory service technicians and application specialists. G S S I A D D S D R I L L H O L E F E A T U R E T O S T R U C T U R E S C A N M I N I X T GSSI, a leading manufacturer of ground penetrating radar (GPR) equipment, announced the addition of a new drill hole feature to the StructureScan Mini XT – the newest generation of GSSI's popular all-in-one concrete inspection GPR system. The drill hole feature is a 3D data processing detection algorithm. The algorithm evaluates a user chosen cylindrical area that represents a potential or planned coring location. Scanning for all potential targets within the cylindrical area, the drill hole feature looks for targets that may interfere with a proposed coring location. Available only within the StructureScan Mini XT user interface, the drill hole indicator is designed for concrete coring applications. In complicated slab situations, the drill hole feature can help users determine the safest location for coring concrete. However, this feature is not a substitute for careful analysis by a trained operator.The new drill hole feature will work with all StructureScan Mini XTs already in the field, and only requires a software update of the system. New units will come with this user interface pre-installed. M C E L R O Y M F G . McElroy introduces new sizes to the Acrobat machine line that feature the revolutionary QuikFit carriage that allows operators to meet the challenges of fusing large-diameter polypropylene pipe in close-quarter working environments. The new machines, which fuse 355- to 630-mm polypropylene pipe, was in response to a demand in the industry for lightweight, large-diameter butt fusion equipment that would make overhead pipe installations more safe and efficient. Fusing large pipe on plumbing and mechanical installations is intricate work whether it 's new construction or a building retrofit. Operators work around ducting, framing, stud walls and other obstacles, leaving little space to fuse pipe, especially when fusing pipe many feet in the air. If the fusion machine is heavy and bulky, it makes the job difficult or even impossible. McElroy custom-designed the Acrobat with QuikFit carriage to break down into multiple components to reduce weight and size. The ability to assemble the upper and lower jaws of the carriage around the pipe by hand eliminates the need for extra equipment and manpower that would be required to lift and fit an entire carriage into a cramped space. The carriage is half the weight of alternative machines and can be arranged in 4-, 3- and 2-jaw configurations for an even smaller footprint. All of the fusion equipment, including the carriage, drill-powered facer, heater and hydraulic power unit (HPU), can be loaded on a single scissor lift platform. W H A T ' S N E W
