Mtengo wokwera wa Crawler scissor, monga nsanja yapamwamba yogwirira ntchito zam'mlengalenga, umagwira ntchito yofunika kwambiri m'mafakitale ndi malonda osiyanasiyana chifukwa cha mapangidwe ake apadera komanso magwiridwe antchito abwino kwambiri. Pulatifomu yotsatiridwa ya scissor lift, yokhala ndi miyendo yothandizira, imagwiritsa ntchito ukadaulo wa automatic hydraulic outrigger. Zotuluka kunjazi sizolimba zokha komanso zimangodzisintha kuti zikhale zosagwirizana ndi nthaka, kuonetsetsa kuti zipangizozi zimagwira ntchito mokhazikika ngakhale m'malo ovuta kwambiri, kupereka malo ogwirira ntchito otetezeka ndi odalirika kwa wogwiritsa ntchito.

Makina onyamulira pakatikati pa chokwera chamagetsi chamagetsi amadalira makina a hydraulic, omwe amayendetsa masilindala a hydraulic kudzera pa mota kuti athe kukweza ndi kutsitsa nsanja yosalala. Izi sizimangothamanga komanso zimakhala zolondola kwambiri, zomwe zimakwaniritsa zofunikira zogwirira ntchito za utali ndi ngodya zosiyanasiyana. Kuphatikiza apo, ma hydraulic system amathandizira kwambiri zida zonyamula katundu komanso kulimba, kuwonetsetsa kukhazikika komanso kudalirika kwakugwiritsa ntchito nthawi yayitali.

Kupititsa patsogolo kusinthasintha kwa magwiridwe antchito, zokweza za scissor zimapangidwa ndi mapanelo apawiri. Gulu limodzi lowongolera lili papulatifomu, kulola wogwiritsa ntchito kuwongolera kukweza ndi kusuntha kwa zida mwachindunji, motero kuwongolera magwiridwe antchito. Gulu lachiwiri lolamulira lili pamunsi mwa zipangizo, kupereka mwayi kwa ogwira ntchito pansi kapena panthawi yadzidzidzi. Chinthu choganizira ndi njira yolumikizirana pakati pa magulu awiri olamulira, kuonetsetsa kuti gulu limodzi lokha likugwira ntchito panthawi imodzi, kuteteza bwino kusokoneza ntchito ndikuonetsetsa chitetezo cha onse ogwira ntchito ndi zipangizo.
