JCB 3CX Eco axles and transmission are designed to withstand a 12,000-hour design life; heavyweight axles are built to withstand serious shock loads. The rear axle alone has a static load rating of 25,000 kg, and a dynamic load rating of 12,500 kg. We use stress-relieved fabrication for the 3CX’s boom – by heating materials to over 650˚C for over 16 hours, we make sure the metal is evenly heated, doubling boom life. The robot welded single-piece chassis on the 3CX maximises strength and minimises weight. The 3CX Eco has been tested all around the world in every conceivable application. Pre-production testing included 100,000 loading cycles, 500,000 excavating cycles, 360,000 gearchange cycles, extensive bump track testing, and thousands of hours of endurance testing. We also carried out 600 performance checks on the production line, as well as extensive EMC (Electromagnetic Compatibility) testing on the 3CX; the latter ensures that signals from mobile phones and radios don’t affect the machine in any way. Our construction materials are tested to the limit by exposing them to extreme temperatures, chemicals, salt, oil and light. That way, we know they’ll survive the most hostile conditions. For rigidity and hose protection, there are flat plate D-pressing loader arms on the JCB 3CX. Hydraulic hoses are approved to work down to -40°C.
