What type of motor is used in excavator?

The vast majority of hydraulic excavators use diesel engines to drive their hydraulic systems. Excavator power varies from mini-machines with 13 HP engines up to hundreds of horses in big-class machines. Larger excavators have multiple hydraulic pumps operating primary and auxiliary systems.

What engines do excavators use?

Excavator equipment is powered by diesel. Diesel offers the ultimate in horsepower to allow maximum efficiency. Fuelling excavator parts in this way is much more reliable than using other products, as diesel can withstand the rigours of major works.
