The 6.7-tonne 65R-1 is JCB’s new midi excavator
JCB CEA has launched the 65R-1 excavator, a mid-sized 6.7-tonne, reduced-tail-swing earthmover designed to be an all-rounder that can be used in a wide variety of jobs.
"The next-generation 65R-1 is the perfect machine," JCB CEA compact equipment product manager Phil Withell says. "Its specification balanced with functional, easy to use features makes it suitable for all applications in the construction, landscaping, civil and DIY markets.
"The range of new features will make every job quicker, easier and more comfortable for the operator."
Among those features are a digger end designed to enhance the excavator’s digging and placing performance, with improved geometry for better lifting and loading, plus a new H-frame heavy undercarriage design which provides stability, strength and rigidity.
An open-centre design allows spoil to fall readily from the carriage, reducing cleaning time when moving between sites.
The JCB 65R-1 — which directly replaces the 8065RTS — can be specified with a range of tracks.
The first machines are set to come with 400mm Bridgestone Pro-Edge rubber tracks, which have a rounded shape at the tip of the embedded core-metal wing. This shape is designed to reduce stress along the edge rubber, which typically suffers damage when operators run over kerbs.
"Pro-Edge gives a four-fold improvement over tracks with conventional-shaped core metals," Withell says.
Also set to enhance performance is a new dozer profile — the revised curvature of the blade improves the dozing and material roll performance but minimises soil retention when the blade is raised.
A new Perkins 35.7kW mechanical injection Stage IIIA engine offers two digging modes, starting automatically in Eco mode but with a heavy mode in reserve should more power be required.
JCB says a new Bosch-Rexroth hydraulic system also improves performance "while offering smooth, precise control and balance".
"A thumb roller on the right-hand joystick controls the hydraulic flow with 10 selectable flow rates and memory function," the company says. "Customers have a choice of dual circuit hydraulics (high and low flow) or just high flow double acting remotes.
"There is also the option to provide combined flow with the dual circuits providing in excess of 145 litres per minute.
"This range of hydraulic options means customers can package the machine to suit their application and budget."
The 65R-1 is fitted with a JCB auto-locking hitch which complies with Australian Standards and the NSW Workcover Position paper on hitches.
