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.

Sandvik will launch its new CI521 impact crusher at AGG1. The crusher is part of the new Prisec CI5xx series of horizontal shaft impact crushers, which the company says provides customers with a low capital cost solution, optimum performance, good cubical shape, and the lowest operating cost per ton. The patented crusher range was developed in response to customer demands, combining the ability to configure one stationary crusher into either a primary or secondary configuration, making it adaptable to a variety of applications.

Superior Industries plans to showcase its new heavy-duty conveyor belt covers at AGG1. The covers feature strong, 22-gauge, corrugated-steel construction that is folded at the edge to nearly double the strength at that crucial point of stress. The corrugated design makes the covers self-supporting, benefitting installation and maintenance efforts by removing the need for additional supports. Installation is not dependent on the location of an idler frame, so owners can attach the covers with self-tapping screws at any point along the length of a conveyor’s structure. The covers are available in standard sizes up to 60 inches wide; in lengths of 41.88 inches; and in styles of full, half, and three-quarter coverage. Custom designs are available upon customer request. Galvanized steel is standard, but other materials are available, including reinforced polyester, stainless steel, aluminum, and fiberglass.
