Fingertip Controls on Joystick

摘要

The Volvo EC20C is powered by a Tier 4-Final 16.2-horsepower diesel engine and sports a new cab and digging equipment design. The operator can now use an electro-proportional fingertip control on the joystick for swing and offset movement at the same time. This enables the EC20C excavator to deliver faster and more precise performance, while reducing operator fatigue, Volvo says. The attachment, circuit, and offset function foot controls have been replaced by the joystick button—providing operators with more leg and foot room. Maximum hydraulic oil flow for the first auxiliary circuit can now be set to adjust the maximum speed of a tilting ditching bucket. Travel speed automatically shifts from high to low according to the working load.
