英国建筑设备制造商JCB发布了3CX挖掘装载机的新版本，该装载机配备了符合EU Stage V排放标准的柴油发动机。
JCB表示，新的55kW机器不仅提高了操作员的舒适度，而且还提高了生产率和性能。
新型发动机安装了柴油氧化催化剂（DOC）和柴油微粒过滤器（DPF）装置，有望实现约8,000小时的使用寿命。
JCB说，其永久密封的曲轴箱通风模块和液压挺杆无需手动调节，从而降低了维修和保养要求，有可能降低总体拥有成本。
3.0升发动机的扭矩比以前的型号高10％，并节省了7％的燃料。
在生产率方面，该机器具有自动调平功能，可确保在崎岖不平的地形上水平运行，而升级的自动驾驶系统使操作员可以轻松选择适于公路行驶的发动机转速。
新的自动两轮驱动可以减少3CX的轮胎磨损和燃油消耗，当不需要额外的牵引力时，可将变速箱从四轮驱动切换到两轮驱动。
当机器倒车或开始高速行驶时，变速箱将自动更改为两轮驱动。
3CX的新型Command Plus驾驶室标配了四个集成式LED信标灯，使操作员无需爬上驾驶室就可以从各个角度看到信标灯，从而提高了现场安全性。现在总共有10个照明灯可供选择，该照明灯与加大的镜子一起为操作员提供了全方位的视野。
装载机的驾驶室除了采用新的内部配色方案外，还具有新的座椅和三辐式方向盘。
新机型还受益于JCB在工厂安装的第一台立体声收音机。它包括兼容蓝牙电话，以及USB、AUX和SD卡功能。
收音机功能显示在新的侧面显示屏上，该显示屏还提供对各种操作菜单的访问。

JCB backhoe gets Stage V upgrade
By Mike Hayes
UK-based construction equipment manufacturer JCB has released an updated version of its 3CX backhoe loader, with an EU Stage V-compliant diesel engine.
The company said the new 55kW machine offers a combination of improved operator comfort, plus increased productivity and performance.
The new engine incorporates a diesel oxidation CATalyst (DOC) and diesel particulate filter (DPF) and promises an operating life of approximately 8,000 hours.
Its sealed-for-life crankcase ventilation module and hydraulic tappets, says JCB, need no manual adjustment, which lowers service and maintenance requirements, potentially reducing the overall cost of ownership.
The company says the 3.0-litre engine delivers 10% more torque than the previous model and estimates a fuel saving of 7%.
In terms of productivity, the machine boasts automatic levelling, ensuring a horizontal operating position on uneven terrain, while an upgraded auto drive lets operators easily select engine speed for road travel.
JCB says both tyre wear and fuel consumption on the 3CX can be reduced with new auto two-wheel drive (2WD), which switches the transmission from 4WD to 2WD when additional traction is not required.
The company says, if the machine needs to dig into a pile or a face, then 4WD can be selected, as maximum tractive effort is required.
When the machine backs away and starts to travel at speed, the transmission automatically changes to 2WD.
The 3CX’s new Command Plus cab comes with four integrated LED beacons as standard, removing the need for the operator to climb up and improving site safety with the beacons visible from all angles. A total of 10 lights are now available as an option, which, along with larger mirrors, offer operators improved all round visibility.
As well as a new interior colour scheme, the loader’s cab has a new seat (plus a headset on the Advanced Easy Control model) and a three-spoke steering wheel that gives an improved view of the redesigned front display screen.
The new model also benefits from the first stereo radio to be factory-fitted by JCB. It includes Bluetooth telephone compatibility, plus USB, AUX and SD card capabilities.
Radio functions are displayed on the new side display screen, which also provides access to various operating menus.
