AGG1 is upon us! Our March issue includes in-depth coverage of AGG1 to help you navigate your way around the show. During the weeks leading up to the show, we have been featuring AGG1 Updates in our Monday e-newsletters to highlight some of the educational sessions and products that will be at the show. Welcome to San Antonio!
Featured Session from the School of Environment, Safety & Health track
T63 — How to Control Dust; Tuesday, March 19, 2 – 3:30 p.m.
Dr. Mark Kestner, NESCO
Dust emissions arise from four principle sources: (1) paved roads, (2) unpaved roads, (3) stockpiles, and (4) material handling and processing operations. This workshop discusses Reasonably Available Control Measures (RACM) to reduce dust emissions from these major source categories. RACM includes operational controls which rely upon operator training, engineering controls designed to contain dust, wet suppression systems, and dry collection. The presentation is designed to enable participants to prepare cost-effective dust control plans that rely upon operational and engineered controls using in-house labor and material that reduce reliance upon more expensive controls.
John Deere says its new 644K hybrid wheel loader, which will be on display at AGG1, uses diesel and electric power and captures regenerated energy as it is created to use in powering the machine. The loader features a 229-horsepower John Deere PowerTech 6.8-liter IT4 engine that runs at an operator-selected constant speed from 900 to 1,800 rpm. The company says the engine’s constant operating speed maintains continuous hydraulic flow at all times to deliver crisp hydraulic responsiveness and reduce cycle times; the electric motor delivers torque resulting in fluid operation and a smooth ride. A PowerShift, countershaft-style transmission maintains smooth shifting. The machine has four operating speed ranges, but no reverse gear or clutches, as direction changes are performed by the electric motor. An integrated, spring-applied, hydraulically released wet-disc park brake is said to require less maintenance.
