A closed box section revolving frame increases strength and reduces stress and makes the JS220 resistant to impact damage.
The JCB JS220 excavator weighs in at around 22 tons (22 t) and is engineered with strength, productivity, efficiency, comfort, safety and ease of maintenance. A closed box section revolving frame increases strength and reduces stress and makes the JS220 resistant to impact damage, according to the manufacturer.
The JS220’s reinforced boom and dipper is made of high tensile strength steel, with single piece wrapper plates and internal baffle plates for long life durability. The machine’s high-strength undercarriage features fully-welded, X-frame construction for long-term durability even in the most demanding applications, and the rigid upper frame provides maximum durability and support. The turret on JS220 tracked excavators is then welded to both the upper and lower undercarriage frames, and stiff, durable doors provide further strength.
A highly efficient JCB EcoMAX TIV emission-compliant engine provides fuel savings of up to 11 percent over outgoing models. A 34,845 lbf (155 kn) bucket tearout makes the JS220 excavators up to 12 percent more productive than competitors, and the special JS range quickhitch system makes attachment changes fast and easy, according to the manufacturer.
Hydraulic regeneration recycles oil across the cylinders for faster cycle times and reduced fuel consumption, and auto-idle technology automatically reduces engine speed when hydraulics aren’t in use.
Simultaneous tracking and excavating is smooth and fast with an intuitive multifunction operation, and four operating work modes allow the operator to tailor performance to any application. Auto, economy, precision and lifting modes provide very different optimized settings. Cushioned boom and dipper ends prevent shock loadings, protect the machine and increase operator comfort, while six viscous rubber mounts minimize noise and vibration. A 70/30 front windshield split for a clear view of the front right track, plus a large laminated glass roof window provide this excavator with all-round visibility.
To keep everything under control, JCB JS220 tracked excavators have a balanced slew and electronic/hydraulic controlled slew braking. Function switches are easy to reach and include the heater and climate control panels, while the side unit doubles as part of the immobilizer code selector.
