Product Description
Built on decades of Japanese engineering precision, the Komatsu PC120 delivers controlled hydraulic performance and mechanical reliability in a compact 12-ton frame. Powering every cycle is the Komatsu S4D105-5 engine — 4.3L displacement, 67.1 kW rated output — paired with a main hydraulic pump delivering up to 323 l/min for consistent, responsive bucket control across demanding dig cycles.
Manufactured in Japan and maintained to high standards, this 2020 unit (working weight: 11,498 kg) is currently located in Zhejiang, China, and is available for global export.
