The reasons for decrease in profitability of the hoisting and transport cars are changes in their speed and loading, deviations of which from optimum values cause a growth in energy loss. Another reason for growth in energy loss of these cars is the process of forced braking when it is necessary to stop the car. Now a new class of hoisting and transport cars with hybrid power plants has appeared which are capable to recuperate the energy of braking and hence to reduce a total power consumption. However, a novel advanced method can be offered for increasing the profitability of the hoisting and transport cars (by means of changing an instant of switching in the acceleration-deceleration cycle), the use of which does not require any expensive devices for recuperating the energy of braking.
