新西兰的移动手术室
英文好的朋友直接看这段介绍：
The 'bus' is a 20-metre long, 39 tonne mobile operating theatre built in Rotorua. It cost $5.2 million and was privately funded. The ‘bus’ carries $1 million worth of video communications equipment.
Truck Specifications
The Prime Mover is a 2001 Freightliner Argosy 110” hi top sleeper cab. It’s powered by a 500 hsp Cummins signature series, coupled to an 18 speed road ranger box. It has one steering axle and two drive axles with full interlock systems, running saf axles and suspension. The tare weight is 9,840kg, with a ladened weight of 19,900 kg on the tractor unit.
One of the major modifications to the unit, aside from the customised styling, is a 60 kva generator that runs off the PTO (power take off). It is capable of running the surgery should there be an external power failure, and is a significant feat of engineering. If power is lost, an onboard UPS provides energy while the truck automatically starts, ensuring a seamless transfer.
A small screen above the driver’s head provides the view for the 5 cameras on the trailer unit for assisting with reversing manoeuvres.
The trailer unit was built from scratch in Rotoura by Mills Tui. It has a tare weight of 22,350kg and ladened weight of 28,400kg. This gives a total tare weight of 32,190kg and ladened weight of 38,240kg for the truck and trailer.
The trailer unit is 2.5m wide and 4.2m in height, and when deployed it extends to 5m in width. Four hydraulic rams level the unit, and another four extend the sides out to their fully opened position.
The total length of the Mobile Surgical Unit is 20m, which requires an over length permit to travel on New Zealand roads. To enable the unit to navigate tight corners and park with precision the bus is equipped with steering axles at the rear. The tri-axle set can turn 30 degrees to assist steering at low speeds. The system is locked while travelling on the road, and is operated via a joystick mounted beside the gear lever in the truck cab.

这辆巴士是一部20米长，39吨重的移动手术室，在罗托鲁瓦建造。（建造）它花费了520万美元，而这些钱主要来自私人募捐。这部巴士上载有价值100万美元的视频通讯设备。
卡车规格：
这辆车的原型是一部2001年的福莱纳“大商船”110，高顶卧铺驾驶室。它的动力由一部500马力的康明斯签名系列发动机提供，与一部18速“道路游侠”变速箱相匹配。它有一个转向桥和两个驱动桥，并且带有互锁系统（可锁止轴间差速器和轮间差速器以应对恶劣路况）,???车轴和悬架。毛重9840千克，挂车上的组件则要19900千克。
对整套车辆最大的改造除了那些定制的设施之外，就是一部60千伏安的发电机，它能够在发动机停止运转的情况下供电。它能够在外接电源出现故障的情况下保证手术进行。如果断电，车载UPS将自动启动卡车，实现无缝转换。
在司机头部上方的一块小屏幕提供了拖车上5个摄像机的视点以帮助司机倒车。
这辆挂车被MILLS TUI在罗托鲁瓦一手建造。它空车重22350千克，满载时重28400千克，这就使得整车（牵引头+挂车）空车重量为32190千克，满载重量为38240千克。
挂车部分宽2.5米高4.2米，展开后宽度可达5米。四个液压油缸使得整个挂车保持水平，另外四个则让它呈现为完全展开的状态。
这个移动手术室的总长为20米，需要特别的超长许可证才能在新西兰的道路上行驶。为了让这部车能在巡航时通过急弯以及精确地停车，这部车在车尾也配备了转向桥。三轴转向组建可以旋转30度在低速的情况下辅助转向。这套系统将在公路行驶时锁定，它们可以在驾驶室里档杆旁边一个操纵杆上进行操作。
