(Continued from Previous Page) of power and setting the hydraulic relief valve higher than needed is a pure waste of energy. The drive and pump motors must be kept clean with good brushes. Brush arc is a waste.

Therefore, it should be minimized by maintaining the motors.

Tires used on electric trucks are very important. Wrong tires can slice two mph olf the top travel speed. That is roughly equivalent to 25 per cent, reflected in wasted energy.

Jackrabbit starts, jockeying lor position and extended use of hydraulics require much more electric power than flat running. As much as 1200 amps may be used to start a truck rolling while only 120 amps will keep it going. Horsepower absorbed in a hydraulic pump is directly proportioned to its load or pressure.

There is one last fuel saving possibility applicable to lift trucksequipment replacement. There's more sense to this statement than meets the eye because ofequipment age, overrating for the job, demonstrable excess fuel consumption.

A new machine may be smaller than its predecessors due to design and materials advances. Weights are reduced, capacities have risen, maneuverability is greater. Less power, therefore, is needed to accomplish a given amount of work.

Narrow aisle equipment, for example, may be more suitable for an application than sitdown-rider type, anyway, and definitely requires less power to propel and maneuver. Using a truck specialized for an application, as narrow aisle vehicles certainly are, has built-in power saving potential.
