JCB’s 8-10 tonne midi excavator models have been updated, to meet the forthcoming EU Stage V emissions regulations. The Dash-2 machines will benefit from a host of detail improvements, making the excavators easier to maintain and to operate.
Key features include:
Stage V compliant JCB By Kohler diesel engines with auto engine stop
New electro proportional control joysticks
Machine health check system
New instrumentation with rotary dial
Fully integrated tie down points
Programmable high and low flow hydraulics
Improved front windscreen visibility
JCB’s 85Z-2, 86C-2, 90Z-2 and 100C-2 compact excavators have been comprehensively updated to meet the EU Stage V emissions standard. All four excavators will continue to use JCB By Kohler diesel engines, that now feature a combined DOC (Diesel Oxidation Catalyst) and DPF (Diesel Particulate Filter) exhaust system. Power outputs are unchanged and engine auto-stop and a one-touch idle feature have been incorporated as standard, to reduce fuel consumption and cut emissions.
JCB’s midi excavators utilise a revised electrical architecture with a 7” operator display, membrane switch panel and rotary controls, similar to that in JCB’s latest 4-6 tonne models. This includes a portrait main screen that can be tailored to customer requirements. There are enhanced safety features, including an advanced lift overload system, that gives a visual indication of the lifting limits of the machine. This incorporates a status bar with a coloured warning system, accompanied by an audible alarm.
The monitor allows both low and high flow circuits to be programmed for use with various attachments, providing optimum attachment performance. During the first ignition cycle for the day, a machine health check screen is displayed. This is designed to highlight to the operator the machine condition prior to the machine being used.
Electro proportional controlled joysticks have been introduced, incorporating swing control on a thumb switch. This increases operator control, while maximising floor space and making the cab easier to clean. The electro-hydraulic dozer lever has been further improved, providing a more accurate control and response to the operator when back filling and dozing. Separate buttons in the control lever head activate the machine’s standard ‘auto kick-down’ two-speed tracking, along with optional dozer float and four-way blade control.
The machines now have four tie-down points integrated into the upper structure and four additional points on the undercarriage of the machine, providing multiple options to secure the excavators for safe and secure transportation.
JCB’s designers have also improved forward visibility from the cab, using a new windscreen surround. At the rear of the ZTS machines, the counterweight is also redesigned, for improved service access. The routeing of hoses and harnesses has been updated, with improved retaining clips, while push-to-connect hoses can now be found on the auxiliary lines. JCB has retained the 100% steel bodywork, 500 hour greasing intervals and 100% bushed dig end, for maximum durability and reliability on site.
