JANUARY 2019 • E&MJ 53 www.e-mj.com EQUIPMENT GALLERY with KINSHOFER's NOX-Tiltrotator. The RBS20 can switch from handling standard mono-block ties to bi-block ties with no mod- ifi cation, thanks to internally and externally fi tted pads. It of- fers removable bolt-on ballast buckets and the ability to handle bi-block ties. The RBS20HPX adds KINSHOFER's low-mainte- nance HPX cylinderless drive with exchangeable shell system for the gripping unit, which achieves 25% greater power than traditional cylinder-driven attachments. All three attachments operate on a 2,880-psi hydraulic circuit. The RBS20 and RB- S20HPX require a second, 5,040-psi hydraulic circuit to power the 15-ton rotator. www.kinshofer.com Data Monitoring and Interpretation for Tires BKT announced SPOTECH, a device that captures information on equipment position traced by satellite and delivers kine- matic motion analysis. The system comprises a triaxial accelerometer positioned on the equipment that records latitudinal, longitudinal, and vertical movements, the forces involved, and speed and cycle dura- tion. The resulting data enables the study of tire usage and the determi- nation of a TKPH value. BKT experts can assist users by interpreting the data and intervening, if necessary, with corrective actions on the tires. www.bkt-tires.com Drilling Solutions Offer Longer Life, Cost Savings Sandvik introduced the Alpha 360, a drilling tool system that complements the company's Alpha 330. Alpha 360 offers a reinforced de- sign, features double the standard thread life, and enables hole accuracy capable of ensur- ing higher productivity, the company reported. It is designed for 48- to 51-mm-hole sizes in face drilling and bolting. The short thread on the round rod gives superior resistance towards bending stresses, improved bit guid- ance and excellent energy transfer, Sandvik re- ported. The thread is guided inside the bit skirt, which enables high-precision collaring in complex rock formations and against uneven surfaces. Separately, Sandvik released the Speedy bit. With 10% high- er drilling speed over a standard bit with ballistic buttons, it is described as the fastest drill bit in the industry. The patented elevated front breaks the rock in two levels and improves the fl ushing fl ow, while large sludge grooves enable quick removal of large cuttings. It can save users one hour per day per rig, the company reported. The bits are available in three sizes: 45, 48, and 51 mm. The Speedy bit features one of the company's two new Power Carbide grades. The new grades, Gradient Carbide and Self-Hardening, re- leased in December, extend grinding intervals and service life by up to 30% over standard carbides, the company reported. The grades offer lower cost per drilled meter, time savings on bit changeouts, and improved safety. The Gradient Carbide grade was developed for abrasive ground conditions with high silica levels in the rock. The Self-Hardening grade was developed for hard, competent ground with homogenous properties through- out. It is so-named due to the enhanced deformation hardening making it more wear resistant as you drill, the company report- ed. The hard top never wears off. www.sandvik.com Light Creates Visible Safety Perimeter The Phoenix Company in- troduced the Danger Light, a heavy-duty LED fi xture that creates a distinct red beam around a shovel pe- rimeter. The 42-watt fi x- ture provides 2,100 lumens of effi cient, LED light, and offers maintenance-free operation. The adjustable harp allows for aim- ing versatility with many equipment models, the company re- ported. The components include fully potted drivers, impact-re- sistant lenses and conformally coated circuit boards. www.phoenixlighting.com
