Leica SpiderQC v4.0
Leica Geosystems introduced Leica SpiderQC v4.0 as part of the new reference station software update that also includes Leica GNSS Spider and Leica SpiderWeb. SpiderQC (previously known as GNSS QC) adds a range of advanced features for multi-frequency, multi-GNSS data analysis, visualization, and numerous other new features, improvements, and optimizations.
SpiderQC provides a suite of tools to help select the best location for reference stations, perform quality control of the reference station data, detect site movements and visualize and monitor the integrity of single base and network RTK corrections in real time.
Volvo’s B series
Volvo’s B series range of EC crawler excavators has been designed to work on some of the toughest terrains under construction. The B-Series crawler excavator range is one of the most diverse in Volvo CE, with the product line stretching from the 13.4 t (29,529 lbs) EC140B to the new 70.3 t (154,980 lbs) EC700B. Creating a low maintenance machine was a key design priority of the B-Series, and all models in the range – EC140B, EC160B, EC180B, EC210B, EC240B, EC290B, EC360B, EC460B and EC700B have been prescribed a variety of features that ensure maximum productivity with maximum uptime. Volvo has achieved this by fitting each machine with an array of advanced technical and ergonomic features as standard.
Palfinger North America has added nine models in its High Performance range to the North American market. The new models in the compact telescopic series include the PC 1500, PC 2700 and PC 3800. This series has been completely redesigned, the company said, and the new models offer up to 15 percent increase in lifting moment and up to 25 percent decrease in dead weight. In addition, they have more reach and an improved slewing system, the company said.
Palfinger offers two new models in the small knuckle boom class, the PK 3400 and PK 4200. Representing a significant advance in small-crane design, the newly developed extension system allows up to 32 feet 2 inches of hydraulic reach, the company said.
Hydrostop Restore & Protect System
Kryton International Inc. has developed a new three-step restoration and protection system for above-grade concrete structures. The Hydrostop Restore & Protect System greatly extends the useful life of aging concrete infrastructure and buildings.
The first step in the system uses a non-shrink waterproof grout to repair cracks and defects at the concrete surface. The product employs Kryton’s original crystalline technology and is named Hydrostop Grout. Once the substrate is repaired, the entire concrete surface is coated with a polymerized, cementitious slurry called Hydrostop Coating. This layer provides a durable barrier against water and chemical intrusion and improves the concrete’s overall aesthetics. The third step creates a long-lasting water repellent effect on the concrete surface by using a high quality blended silane-siloxane sealer called Hydrostop Sealer.
