The company says this enables greater production through rapid, smooth motion into and out of the gyratory crusher rock box, thereby increasing the number of truck dumps per hour and overall tonnage through the crusher. The "smart" boom features a higher horsepower electric motor, higher flow-rate pumps with constant horsepower control, high-flow directional control valve, and an electrical boom position feedback for speed and pressure control. The company says the system is easy to use and intuitively responsive to the joystick operation, making it the next generation of boom system. Write 51 on reader card. Bi-fuel engine The new bi-fuel, 16-litre Tier 4 Interim engine from Volvo Penta is fueled by a precision blend of natural gas and diesel fuel to provide fuel cost savings and high power density. The TWG1663GE is 100-percent Volvo Penta, with no add-on aftermarket systems re- quired. Natural gas is introduced upstream of the turbo-chargers, and an electronic air valve controls the amount of natural gas mixed. Engine compression ignites the diesel fuel, which in turn ignites the natural gas. Bi-fuel blending and combustion control is integrated into the engine management system.
