WABCO 150-Ton Electric Truck - Facts and Features 720374
The Wabco Model 150-B mining truck was announced in late 1970, and during 1971, over 40 of them were delivered to various customers in this hemisphere. It employs various powerplants up to 1600 hp, which gives it a very favorable horsepower-to-weight ratio for vehicles in this size category. The 36 X 51 in tires provided are more than adequate for this vehicle, as the low air pressure at which these tires can be operated minimizes tire failures from road obstructions and provides extremely long life. The d-c drive system recently developed by General Electric for vehicles of this size class utilizes operational principles and design features that were successfully employed in smaller drive systems of this type, currently installed in over 1300 vehicles with engines up to 1000 hp. This paper describes the features of construction of this vehicle and the unique attributes of the pneumatic and hydraulic system.
