Engine A very low fuel consuming engine which conforms to European requirements for “low exhaust emission” Tier 2 in accordance with directive 97/68/EC. Particularly suitable for urban work, these engines have significantly reduced noise levels, one of the lowest fuel consumptions on the market. Engine rotation speed checking via an electric potentiometer. Manual return to idle, control on RH control lever. Engine pre-heating.
Hydraulic system 2 variable displacement axial piston hydraulic pumps feeding the attachment, the travel and the swing. Maximum flow................................................................ 2 x 71.4 l/min 1 gear pump feeding the dozer blade and the boom offset Maximum flow................................................................ 1 x 25.4 l/min Safety valve pressure: Attachment............................................................................. 294 bar Swing...........................
Cab With CASE machines, "smaller machine dimensions" don't mean that there is less space for the operator. The CX75SR cab has the same level of comfort and convenience as the standard models in the CX range; it is integrated with the upperstructure and therefore does not affect manoeuvrability on 360° swing.
Undercarriage LC type undercarriage providing excellent stability (as a result of its length) and loading capacity comparable to machines of standard dimensions. Steel or rubber tracks are available. Upper and lower tracks equipped with bushings and seals. Travel motors protected and incorporated in the undercarriage. Track tension adjustable by grease cylinder. SPECIFICATIONS (per track set) Number of upper rollers.......... 1 Number of lower rollers.......... 5 Number of track pads............
Upperstructure The “short radius” CX75SR has special specifications compared to “standard” models: • Shorter upperstructure radius for the rear part. boom foot is positioned close to the upperstructure swing axis so as to have the minimum attachment • The front swing radius. • Cab is within the upperstructure swing radius . • The width of upperstructure is close to the width of the undercarriage (using standard track pads).
