JS145 CRAWLER EXCAVATOR
MEETS TIER 4 INTERIM WITHOUT DPF
JCB’s JS145 crawler excavator made its debut at CONEXPO-CON/AGG this year. The 14.5 tonne (32,000 lb) machine is powered by the award-winning JCB Ecomax diesel engine, delivering a powerful 108 hp (81 kW). As with all 4.4-litre Ecomax engines, these motors meet the US EPA Tier 4 Interim/EU Stage IIIB emissions standards without using a bulky, expensive diesel particulate filter (DPF) or an exhaust after-treatment system such as selective catalytic reduction (SCR).
Revised hydraulics and improved control systems, in combination with the highly efficient Ecomax engine, results in fuel savings of up to 10 percent for the customer in normal excavation duties. The lack of a DPF or SCR system also allows the JCB designers to fit an engine cover that is considerably lower than some competitors, improving visibility and safety on site. The JS145’s hydraulic circuits and pumps have been optimized to deliver improved efficiency and machine performance. Through a new “Smart Control” LCD monitor in the cab, operators can fine tune the automatic idle facility.
