The business of mining exacts a tremendous toll
on the people and machines used to extract ore or
coal from the ground. At Hitachi, our first priority is to lighten their load.
Power to carry the mail
AC drive technology is a very efficient means of powering large haulers. AC drives allow smoother acceleration at slow speeds, better grade-ability, and higher top speed. AC drives also minimize routine maintenance with their brushless design.
More retard, less braking
One of the most significant advantages of a diesel-electric drive system is the powerful, dynamic retard capability which minimizes brake wear. The same electricity that is used to propel the hauler can be switched by “braking choppers” into resistance that can be used to slow the traction motors. Dynamic retard is so effective that the hauler can be slowed to .5mph (0.8 km/h)without the operator ever touching the brakes.
