BELAZ launches innovative dump truck E quipment manufacturer BELAZ recently launched a 130-ton hybrid rigid dump truck, with an innova tive drive system, which is the combination of a low-power diesel engine, battery bank and an

and hydraulics. During the braking stage, the electric motors work as generators, adding energy to the trac tion batteries and thus, on a descent, re-generating energy back to the battery pack. During loading / dumping, the truck uses engine power to charge itself. As a result, a full replenishment of the energy consumed by the dump truck when moving uphill, is ensured. The dump truck is also equipped with a proven and very efficient AC/AC drive system. Another important feature of the new develop ment is the removable batteries, which can be easily replaced. At the request of the client, the dump truck can be delivered without batteries and, once on site, can be fitted with rented batteries, which makes the purchase of hybrid dump trucks even more affordable and attractive. BELAZ plans to manufacture hybrid mining dump trucks in other payload classes, primarily in the popular segments of 90 and 220 tons. Mynbou Rigs Afrika Pty Ltd

energy recovery (re-gen) system, aimed at significantly reducing harmful emissions into the atmosphere and at reducing – as a result of fuel savings – the cost of operating a dump truck. The BELAZ hybrid is equipped with a YaMZ-845 diesel engine with a power output of 537 kW instead of 1 194 kW in the standard specification, as well as a power storage battery pack consisting of several rechargeable lithium-ion batteries with a total power of 730 kW. Batteries combined with a diesel engine ensure that the machine runs smoothly throughout the work shift, without stopping to recharge batteries. If necessary, it is possible to charge the batteries from an external charger. BELAZ-7513M is equipped with an energy recovery system that allows braking by both electric traction motors without the use of brake discs, brake pads
