TOOLS FOR THE TRADE Viscosity Sensor Reduces Energy Output for Portable Asphalt Plants Brookfield Engineering Laboratories’ AST-100 viscosity sensor, used in systems put together by Motion Engineering, have dramatically reduced energy output and costs for bag house protection. There are many reasons why viscosity control is important to kiln and burner operations. Poor combustion caused by fuel that is too viscous or from oil that has been pre-heated to too high of a temperature can contaminate the bag house, which filters the exhaust gases from the kiln. Unburned oil from incomplete combustion can wreck the filter bags, which are expensive to replace. Use of a viscosity sensor can also eliminate the need to keep pre-heat temperature above the set-point to achieve a proper viscosity, which wastes energy. For more information about Brookfield viscosity instruments call 508-946-6200, visit www.ViscosityJournal.com, or e-mail sales@brookfieldengineering.com Vögele America Introduces New Asphalt Pavers The Vision Series includes the 10-ft. tracked Vision 5200-2 and 10-ft. wheeled Vision 5203-2, and the 8-ft. tracked Vision 5100-2 and the 8-ft. wheeled Vision 5103-2. The Vision models are quieter, cooler, and more productive than Vögele America’s predecessor models. Operators will benefit from outstanding forward and all-around visibility. The operator can see the sides, the hopper, and the conveyors in the back, without having to move around. The operator’s stations swing out from both edges of the machine, for superior visibility to the sides, behind and into the hopper. With its Tier III engines, the Vision Series suppresses noise and redirects exhaust and heat away from operator and crew, with raked, streamlined exhaust pipes. Self-diagnostics are built into pavers, with fluid levels and other inspection points monitored from a display panel. An optional hydraulic front apron eliminates much shoveling in front of the paver. The Vision Series’ self-tensioning conveyors have hydraulic cylinders that keep them adjusted.

Utility compactors from Caterpillar CB14, CB14 XW and CB14 Full Flush Utility Compactors are ideal for commercial site preparation, landscaping, small soil applications, patching, driveways, city streets, roads, alleys, or for adding paths to parks, recreation areas and small parking lots. The CB14 has a compaction width of 31 inches while the CB14 XW utilizes a drum width of 39 inches. The CB14 full flush version utilizes a 35-inch offset front drum that provides full flush compaction close to curbs, walls and other vertical obstructions. All three models are powered by a quiet three-cylinder Cat C1.1 diesel engine that provides a gross power of 16.1 kW (21.6 hp). The engine is liquid cooled and operates at 2,400 rpm. The engine meets U.S. Tier II emission control standards. The operator’s station provides plenty of legroom and ensures a comfortable operating environment. The CB14 and CB14 XW have a high-curb clearance, allowing them to work along vertical obstructions while the CB14 Full Flush model with its offset front drum provides total flush compaction on the right side.
