Q57
A direct rope haulage pulls 8 tubs loaded with coal through an incline of length 500 m having an inclination of 1 in 6. Consider the following additional data. Capacity of tub = 1.0 tonne. Tare weight of tub = 500 kg Hauling speed = 9 km per hour Coefficient of friction between wheel and rail = 160 Coefficient of friction between rope and drum = 110 Mass of rope per meter = 1.5 kg The minimum power required to haul the tubs in kW is
A direct rope haulage pulls 8 tubs loaded with coal through an incline of length 500 m having an inclination of 1 in 6. Consider the following additional data.
Capacity of tub = 1.0 tonne.
Tare weight of tub = 500 kg
Hauling speed = 9 km per hour
Coefficient of friction between wheel and rail =
Coefficient of friction between rope and drum =
Mass of rope per meter = 1.5 kg
The minimum power required to haul the tubs in kW is
