Strength: Why Compromise?
The JCB 3CX-14 SUPER backhoe loader features a robot-welded, single-piece chassis for maximum strength and reduced weight. For rigidity and hose protection, the loader arms utilize a flat plate, D-pressing design. Additionally, the boom benefits from stress-relieved fabrication methods, and heat treatment at 1202?F (650?C), to double the expected boom life. An inner-box extending dipper means less weight is extended and moved while excavating, for reduced stress on the machine and increased stability.
The heavyweight axles on the 3CX-14 SUPER are designed on conjunction with the transmission for a 12,000-hour life. The rear axle has a static load rating of 55,116 lb (25,000 kg), and a dynamic load rating of 27,558 lb (12,500 kg).
Hydraulic hoses are approved to work at temperatures as low as -8°F (-40°C).
The pre-production testing regime for the 3CX-14 SUPER included 100,000 loading cycles, 500,000 excavating cycles, 360,000 gear change cycles, in addition to extensive bump track testing, and thousands of hours of endurance testing. Additional EMC (Electromagnetic Compatibility) testing ensures that the machine is not affected by signals from cell phones and radios. Construction materials are tested for tolerance to extreme temperatures, chemicals, salt, oil and light, to withstand the most hostile conditions.
Every new 3CX-14 SUPER is put through 600 performance checks before rolling off the production line.
