CASE CX145CSR Short Radius Excavator

Model Comparison Product Features Attachments Specifications

The CASE CX145C SR delivers powerful performance in a compact footprint. Built for operators who need strength, stability, and reach in tight environments, this short radius excavator combines the efficiency of CASE’s Intelligent Hydraulic System with a proven Tier 3 ISUZU engine. The result is smooth, responsive control with impressive digging and lifting capability across every application. Designed for demanding work on roadsides, bridges, and busy urban environments where space is tight, the CX145C SR brings big-machine capability into confined worksites, making it ideal for civil contractors, local councils, and construction crews who need to dig, lift, and load safely and efficiently in restricted areas while maintaining low noise levels, reduced fuel consumption, and the reliability that CASE machines are known for.

Product Features

Every detail of the CX145C SR has been engineered for reliability and low ownership costs. Robust construction, high-quality components, and a heavy-duty undercarriage ensure durability in tough conditions. All filters and service points are accessible from ground level, while CASE’s standard EMS bushings extend greasing intervals to 1,000 hours, helping you spend more time on the job and less on maintenance. Inside the ROPS/FOPS Level 2 cab, operators benefit from automotive-level comfort with an adjustable suspension seat, advanced climate control, and a wide glazed area for outstanding visibility. The full-colour multifunction display provides real-time machine data, on-board diagnostics, and an ECO gauge for monitoring fuel efficiency, giving you total control and confidence in every task.

Short Swing Radius

The CX145C SR’s short radius design delivers exceptional power and stability in tight areas. It’s ideal for road construction, bridge work, and urban projects where space is limited, letting you dig, lift, and swing safely without the risk of machine damage or reduced performance.
