CASE Short Radius Excavators
SHORT RADIUS EXCAVATORS
FULL PERFORMANCE. REDUCED SWING.
CASE CX145C SR | CASE CX235C SR
CASE Short Radius Excavators combine strong digging performance with precise hydraulic control where working space is limited. Their reduced rear swing helps operators work confidently near buildings, traffic lanes, retaining walls and other site boundaries. Designed for civil works, road construction, utilities, drainage and urban development, these machines deliver productive excavation while requiring less space for upper-structure movement.
Ideal for civil contractors, councils, utility crews and plant hire businesses working on restricted or high-traffic sites, the range balances capability with practical site access. Supported by Brown and Hurley Agriculture, operators can choose a short radius excavator suited to their working area, attachment requirements and production targets.

CASE CX145C SR 14.9 tonne
The CASE CX145C SR combines a 70.9 kW Isuzu Tier 3 engine with a compact 1,490 mm rear swing radius and the CASE Intelligent Hydraulic System. Its short-radius design helps operators work around roads, bridges, walls and other confined areas, while 3 selectable power modes and Auto Power Boost provide responsive control for digging, lifting and precision work.
The standard monoboom configuration provides a maximum digging depth of 5.51 m, maximum reach of 8.29 m and Power Boost digging forces of 95 kN at the bucket and 66 kN at the arm. A standard blade, ROPS and FOPS Level 2 cab, air-suspension seat, automatic climate control, multifunction colour monitor and rear-view camera support versatility, comfort and visibility.
CASE CX235C SR 24.2 tonne
The CASE CX235C SR combines a 117.3 kW Isuzu Tier 3 engine with a compact 1,720 mm rear swing radius and the CASE Intelligent Hydraulic System. Designed for road construction, bridge projects and urban worksites, it provides the digging capability of a 24 tonne class excavator while helping operators work efficiently around traffic, structures and confined site boundaries.
With the 2.94 m arm, the CX235C SR provides a maximum digging depth of 6.65 m, maximum reach of 9.85 m and Power Boost digging forces of 152 kN at the bucket and 110 kN at the arm. Three working modes, auxiliary flow settings, a ROPS and FOPS Level 2 cab, suspension seating, automatic climate control and a multifunction colour monitor support productive operation.
