小前移FMR是shi與yu前qian移yi式shi叉cha車che功gong能neng相xiang近jin的de一yi款kuan。其qi功gong能neng結jie合he了le電dian動dong堆dui垛duo機ji與yu平ping衡heng重zhong叉cha車che的de優you點dian
，當dang門men架jia前qian伸shen至zhi頂ding端duan，荷he載zai重zhong心xin落luo在zai支zhi點dian外wai側ce，此ci時shi相xiang當dang於yu平ping衡heng重zhong叉cha車che；當dang門men架jia完wan全quan收shou回hui後hou，荷he載zai重zhong心xin落luo在zai支zhi點dian內nei側ce
，此ci時shi即ji相xiang當dang於yu電dian動dong堆dui垛duo機ji。這zhe兩liang種zhong性xing能neng的de結jie合he，使shi得de在zai保bao證zheng操cao作zuo靈ling活huo性xing及ji高gao荷he載zai性xing能neng的de同tong時shi，體ti積ji與yu自zi重zhong不bu會hui增zeng加jia很hen多duo，大da幅fu度du節jie省sheng作zuo業ye空kong間jian，適shi合he更geng多duo場chang合he使shi用yong。
