澳大利亞SUMI叉車公司是唯一的南澳大利亞國有公司，生產廣泛系列的特為澳大利亞，東南亞市場設計的強勁、簡潔、可靠的電動叉車。SUMI的前身是由1982年由兩位阿德萊德商人創建的，最初為組裝，銷售與服務美國大喬公司生產的車輛，這些車輛并不能充分地滿足澳大利亞用戶的需求，對于亞洲市場的需求及其有限的場所來說也顯得體積太大。基于認識到這些，于1987年一個現代的，定位極強的工廠在達德利園區建立起來，開始生產新系列的特別為滿足這些市場需求而設計的車輛。
SUMI Lift Trucks Pty Ltd is a solely South Australian owned company, producing a range of robust, compact and reliable battery electric forklifts, designed specifically for the Australian and S/E Asian markets. The company evolved from a company set up in 1982 by two Adelaide businessmen, initially assembling, selling and servicing American manufactured Big Joe trucks. These trucks did not adequately meet the needs of Australian customers and were often too large for the requirements of the Asian market and their more compact environment. With this in mind, a modern, purpose built factory was constructed in 1987 at the Dudley Park site, to produce a new range of trucks designed specifically to meet the needs of these markets.
