Caterpillar launches new motor graders
07 June 2010
Caterpillar has launched four new K Series motor graders to replace the existing standard H Series. The new K series has been designed for lesser-regulated markets and features EU Stage II emission compliant engines.
The 120K, 12K, 140K and 160K are all fitted with 7,2 l Cat C7 ACERT engines producing up to 108 kW, 126 kW, 141 kW and 152 kW respectively. The four new graders have base weights of 12 tonnes, 13.7 tonnes, 14.1 tonnes and 15.1 tonnes.
The range-topping 160K is equipped with a 4.3 m mouldboard while the other three graders all feature 3.7 m mouldboards.
A Caterpillar spokesperson said, "The K Series builds on the legacy of the H Series and incorporates a variety of enhancements to enable customers to increase production, directly impacting on their bottom line.
"Thanks to the ACERT engine, the K Series delivers a torque increase of up to +10% depending on application. The Series also offers automated machine control and guidance with AccuGrade Ready as an option."
All four models are equipped with Caterpillar's variable horsepower feature (VHP), which increases productivity by matching power to ground speed.
In first and second gears, where traction is limited, the engine's power is automatically reduced to help reduce fuel consumption and tyre slippage. In third gear, the power management system makes a further 7.5 kW of power available, while in gears four to eight, maximum power is available to the operator. "This allows the operator to maintain maximum rimpull while increasing ground speed and productivity," said the spokesperson.
Extended service intervals and grouped service points reduce machine downtime, while improved diagnostic capability through Caterpillar's electronic technician (ET) leads to fast trouble-shooting across multiple systems, again decreasing machine downtime and maintenance costs, according to the company.
A new electronic throttle control (ETC) provides more precise throttle operation, while the addition of Caterpillar's electronic clutch pressure control (ECPC) allows for optimum creep modulation, providing better feel to the operator.
