JCB torques up its shovel

摘要

In redesigning its flagship 457 loading shovel, JCB has increased the load-handling capacity to 6.5 tonnes, fitted a Stage IIIB engine and implemented a host of other upgrades and options. Now weighing in at 19.3 tonnes, the new 457 has an 8.9-litre engine providing 186 kW of power and 1,085 Nm of torque - up 16 and 18 per cent respectively compared with the 456 model it replaces.
