原文:
The Heavy Expanded Mobility Tactical Truck (HEMTT) provides transport capabilities for re-supply of combat vehicles and weapons systems. There are five basic configurations of the HEMTT series trucks: M977 cargo truck with Material Handling Crane (MHC), M978 2500 gallon fuel tanker, M984 wrecker, M983 tractor and M985 cargo truck with MHC. A self-recovery winch is also available on certain models. This vehicle family is rapidly deployable and is designed to operate in any climatic condition where military operations are expected to occur.

美軍輪式車輛中的重型運輸車是指載重量在8－10噸以上的車輛。

美軍現裝備的重型運輸車主要有M915系列14噸級車、M123系列10噸級車和M977重型擴大機動性運輸車等。

近年來，由於美軍軍費緊縮，使運輸車輛現代化建設進程受到嚴重影響。

按20世紀90年代車輛發展規劃，美軍特別重視重型車的標準化建設。美軍裝備部隊的重型運輸車主要是M977重型擴大機動性戰術卡車（HEMTT）原型車就不貼了，貼點特殊的型號。

車種介紹：

M978型加油車是美陸軍加油車隊的主力，用M977型10噸8×8重型擴展機動性戰術卡車底盤改裝，備有功率445馬力的柴油發動機，有良好的越野性能和較高的行駛速度，幾乎能給所有的車輛伴隨加油。

該車油罐容量9450升，可同時為2輛戰車加油，加油速度1135升∕分。

資料補充:

M977重型擴大機動性戰術卡車

為提高後勤運輸車輛性能並節省經費，美陸軍與美國奧什卡什公司對美軍在役的重型擴大機動性戰術卡車進行了改造。1995年9月，該公司接受了一份對123輛M977進行解體檢修的合同。被解體的HEMTT被送到新車裝配線進行檢修，並換裝多個新型子系統，使其性能與新車基本相同。此解體檢修計劃還擴展到了HEMTT中的M985、M987等車型。


此「擴展維修計劃」與這裡的解體檢修計劃的區別是增加了一些新的子系統。奧什卡什公司已將這些新的子系統在增強型HEMTT上試用，使該車成為陸軍機動性最強的一種載重車。


　　增強型HEMTT的主要改進是增加了獨立懸架、安裝了中央輪胎充放氣系統和使用了永久潤滑部件。使用獨立懸架後，車輛上彈簧的行程比目前的設計標準增加了1倍，乘員和貨物更加平穩，牽引力和離地間隙也有所增大，涉水深度由1．2米提高到1．5米。中央輪胎充放氣系統可供司機在任何條件下將車輛性能調整到最佳狀態。

永久潤滑系統（包括傳動軸、球鉸接件和控制臂樞軸）確保了更好的野外使用性能，並能節省維修保養費用。美軍重型運輸車的發展趨勢總的看來是在盡量採用民用車的基礎上重點發展和改進軍用車。
