JCB’s 13-ton 131X and the 15-ton 150X tracked excavators can be used by construction, utility, and rental fleets.
The 131X is equipped with the 74-hp JCB EcoMAX engine that requires no replaceable diesel particulate filter (DPF) or diesel exhaust fluid (DEF). The 150X is powered by the 109-hp JCB EcoMAX engine that requires no replaceable DPF. Other key features include a wider, quieter cab and higher-diameter pipework to boost hydraulic efficiency.
While the X Series excavators use JCB’s boom and arm design, the larger bucket cylinder on the 150X delivers an 11% increase in bucket tearout force. Additionally, the power boost duration is increased from 3 seconds to 9 seconds, allowing maximum bucket and dipper tearout for longer periods. To match these improvements, the hydraulic oil cooler size is increased by 15% compared to earlier models for superior cooling performance.
The 150X is also equipped with a larger Kawasaki hydraulic pump that can run at lower engine speeds, allowing 6% more productivity. And fine tuning of the Kayaba valve block to improve flow sharing has created an 8% improvement in productivity for grading operations.
The 131X benefits from similar performance enhancements and lower operating costs. JCB’s Auto Idle and Auto Engine Stop features contribute to fuel savings of 5% compared to the previous JCB 13-ton model and up to 27% compared to competitor models. Performance is also improved, with breakout force increasing to 22,931 lb.-ft. Like the larger model, the 131X benefits from improved cooling efficiency by way of a larger, electronically-controlled proportional engine fan.
