Olsem mipela i tok pinis antap, ol 'slewing drive' em ol 'full-circle rotary reduction mechanisms. Ol gutpela samting bilong ol i go moa long dispela. Taim ol komponen na lod we ol bikpela na liklik 'slewing drive' i draivim i ken senis planti taim, ol sais bilong ol, moa yet ol 'axial' sais bilong 'drive train', i wankain. Dispela i helpim wok bilong stretim ol samting we i konektim ol samting insait long ol 'series transmissions', na dispela i daunim sais bilong ol masin ikwipmen.
Na tu, tupela 'gear' na 'worm gear slewing drives', bikos i gat bikpela senis namel long ol 'driving' na 'drivend' komponen, i save kisim bikpela 'transmission ratios', na dispela i no isi long planti ol narapela kain 'variable speed transmissions' i save mekim.
