JCB is releasing four more models of midi excavators, with operating weights of 4.8-5.7 tonnes: the 48Z-1, 51R-1, 55Z-1 and 57C-1 (pictured above).
They are available in conventional, reduced and zero tailswing configurations. Key features include: 500-hour greasing intervals, improved cab instrumentation, increase in the 57C operator’s cab capacity, improvement in visibility and bucket tearout, additional dump height and more powerful bucket tearout force.
JCB has revised the pin pick-up points to work with a number of competitive bucket brands, while optional hydraulic or manual quick hitches can be specified for faster attachment changeover.
The biggest development in the cab is in the display screen and control system, with an automotive- style rotary controller allowing easy access to a host of systems and information.
The operator can set auxiliary hydraulic flows for two separate attachments from the cab, while the menu mode button switches the rotary controller between throttle modes.
The midi machines now have nine power modes available, including Eco and for the first time an H+ heavy digging mode. All four excavators can be supplied with a choice of Stage IIIA/Tier 4 Interim Perkins engines or Tier 4 Final engines from JCB by Kohler, to suit various territories.
They come with JCB’s LiveLink telematic monitoring and location service, providing customers with machine working hour data, fuel level and consumption information and critical system alerts.
