Compact trommel wheels out for heavy-duty production
With heavy-duty features including a six-yard hopper and optional tipping grid, the new 516 model from McCloskey combines a dramatic reduction in transport size with upsized feed and conveyor components for increased throughput.
The wheeled 516 REP model (equipped with radial stacker, end conveyor and pintle hitch) offers the industry’s highest production rates for trommels compatible with simple pintle-hitch towing. The unit is designed to be pulled easily behind any heavy-duty truck or loading equipment normally found in construction and aggregate fleets.
The 412 R, also a wheeled, pintle-towed trommel, was the first McCloskey machine to make extensive use of folded steel plate in the chassis, in place of a traditional welded construction. Using folded plates gives the design engineers greater structural strength and more flexibility for their internal configuration of the trommel.
Despite its compact travel size, the new trommel features a 6-yard feed hopper, 50 percent larger than previous models, plus wider conveyor belts to match. The feed belt and stacker belts have both been upsized from 30 inches to a 36 inch width, while the new oversize belt weighs in at a “monster” 42 inch width. The 516 retains the same 5-foot by 16-foot drum screen used by its predecessors.
The 516 REP travels on a new tandem undercarriage specifically designed to minimize weight on the pintle hitch. With dual tires on each corner and front leaf springs, the tandem spacing is optimized to carry 90 percent of the machine’s wheels, and less than 2,500 pounds on the hitch. The undercarriage is equipped with air brakes as standard, with an option for electric brakes.
The 516 REP is offered with an optional tipping grid for scalping off reject material in heavy-duty applications. The grid can also be tipped out of the way to provide a clear path into the hopper when screening finer material.
