Case CX145C

Key Features:

  • High maneuverability in restricted conditions due to compact boom placement
  • Tough conditions are overcome with Power Boost
  • Controls include one-touch idle, and one- or two-position mode selector
  • Tier 4 certified engines
  • Greatly reduced noise levels
  • Ground-level service and fluid checks
  • Daily maintenance checks made easy with ground-level access to key components


Unlike traditional excavators with prominent rear counter-weights, the CASE CX145C SR excavator features a compact counterweight and boom placement that minimizes the machine’s work envelope. The small swing radiuses make maneuvering onto difficult, restricted sites a breeze. Daily maintenance on the CX145C SR is made easy with service checks from ground level and extended maintenance intervals. Tier 4 engines meet current environmental standards while lowering fuel consumption.
