CONSOL Energy Inc, a multifaceted company producing coal and natural gas and providing transportation and other energy services, has purchased a Bucyrus Un-A-Trac 488D XP LHD (Load Haul Dump) diesel scoop.

Purchase decision was primarily because of its safety features and operational benefits. This is the first diesel scoop supplied by an OEM to be approved for underground use in West Virginia. CONSOL will use the 488D XP for section supply and rehabilitation.

Eliminating the need for batteries and battery maintenance, the Un-A-Trac 488D XP offers the cleanest power pack available for underground mining. The vent rate of 212 m³/sec is almost half that of the closest competitor for a cleaner working environment, and the particulate index of 4500 cfm reduces emissions by over 66% compared to competitive products.

The design offers the lowest operating height of any mine-approved diesel scoop, increasing operator visibility. Diesel power means the scoop can handle severe conditions without interruption for battery charge, change, or cooling. It can also negotiate gradients that would overheat electric tram motors and drive components.

The four-speed power shift transmission lets the operator adjust tramming speed and torque to the current needs, and the SAHR (Spring Applied, Hydraulic Release) brakes achieve 0.5 g deceleration.
The quiet engine and exhaust system and ergonomically designed cab with a control stick provide a comfortable environment for the operator.

The scoop has a lift capacity of 14.5 tonnes, and the 152.4 cm vertical lift means it can dump onto elevated transfer points without additional equipment. The Bucyrus Quick Attach System allows use of a versatile range of attachments. The axle is rated for load of 36 t, while the rolling element oscillation bearing is rated at 26 tonnes axial, 60 tonnes radial.

The Un-A-Trac 488D XP diesel scoop is equipped with a flameproof electronics package and a 150 HP turbocharged, aftercooled engine. The engine is cooled by a massive, 8-fin-per-inch, triple-pass radiator assembly. An analog temperature control manages cooling fan demand and response, reducing the operator’s exposure to noise.
