The new machine weighs in at up to 20tonnes and features an engine power increase of 7% over the previous model, boosting performance and productivity. Digging output is increased due to features such as a 200mm longer monoboom, and a maximum bucket capacity of 1.14m3. Lifting capacity is increased and the PC190-8 lifts over a tonne more than the PC180-7, while it offers a bucket digging force of 1.2tonnes, which Komatsu claims is the best in its size class. The machine is available with different arm lengths, two piece boom arrangements and an optional narrow track undercarriage. In addition, the machine can be configured for an array of specific applications such as working demolition operations with extra protection.
The operator has a choice of five main working modes that can be used to optimise performance to suit the application. An economy setting offers reduced fuel consumption while delivering high productivity in levelling or loose material digging jobs while at the other end of the performance spectrum the high power mode suits bulk excavation work.
The cab is said to offer high comfort with a suspension seat, air conditioning and ergonomic controls. Visibility is said to be good while the machine also features the innovative roll-over protection cab, which Komatsu has developed for its excavators to boost safety. The cab now has an integrated frame made of tubular steel to protect the operator, while other safety features include a rear-view camera and anti-slip steps.
As with other recent Komatsu machines the new PC190-8 is equipped with the firm's sophisticated KOMTRAX package. This system uses satellite communications technology to provide continuous machine management and monitoring functions. Data such as fuel consumption, working time, machine location is all recorded and the excavator can also be set to operate in certain geographic areas only or to notify personnel by email or text automatically if it is moved unexpectedly.
