    手shou動dong單dan梁liang懸xuan掛gua起qi重zhong機ji日ri常chang操cao作zuo需xu求qiu專zhuan業ye操cao作zuo人ren員yuan
，電dian動dong單dan梁liang起qi重zhong機ji也ye需xu求qiu船chuan長chang操cao作zuo。首shou先xian
，從cong定ding義yi出chu發fa
，手shou動dong單dan梁liang起qi重zhong機ji是shi指zhi起qi重zhong機ji的de操cao作zuo
，起qi升sheng組zu織zhi的de工gong作zuo由you人ren力li完wan結jie。一yi般ban選xuan用yong鏈lian條tiao驅qu動dong，大da鏈lian輪lun驅qu動dong，達da到dao省sheng力li的de效xiao果guo。手shou動dong起qi重zhong機ji現xian在zai有you規gui範fan產chan品pin。電dian動dong起qi重zhong機ji有you地di上shang作zuo業ye和he司si機ji室shi作zuo業ye兩liang種zhong方fang式shi。地di上shang操cao作zuo選xuan用yong電dian動dong操cao作zuo，司si機ji室shi操cao作zuo類lei似si於yu手shou動dong單dan梁liang起qi重zhong機ji。

    從cong理li論lun上shang講jiang
，手shou動dong單dan梁liang起qi重zhong機ji與yu電dian動dong單dan梁liang起qi重zhong機ji的de首shou要yao差cha異yi在zai於yu動dong力li原yuan理li的de不bu同tong。隻zhi需xu手shou動dong單dan梁liang起qi重zhong機ji結jie構gou合he理li，理li論lun上shang水shui平ping移yi動dong不bu需xu求qiu太tai大da的de力li。簡jian單dan地di說shuo，沒mei有you光guang滑hua和he車che輪lun，人ren們men隻zhi需xu支zhi付fu分fen量liang的de15%來移動
；當運用軸承和車輪時，理論上隻需求分量的0.1%-0.3%。
