C = Yuav tsum muaj peev xwm thauj khoom ntawm casters
L = Qhov siab tshaj lub laub load
W = Thawv nyhav
n = tus naj npawb ntawm cov casters siv
SF = Safety Factor
Tsheb thauj mus los sab hauv tsev = 1.35 (tsawg dua 3 mph)
Sab nraum zoov tsheb thauj mus los = 1.8 (tsawg dua 3 mph)
Sab hauv lub zog tsav tsheb thauj mus los = 2 (tsawg dua 3 mph)
Sab nraum lub zog tsav tsheb thauj mus los = 3 (tsawg dua 3 mph)
Cov hauv qab no yog ib daim ntawv yooj yim ntawm qhov sib npaug rau tus qauv 4-caster lub laub nrog 2 universal thiab 2 directional casters, nrog rau qhov hnyav hnyav ntawm txhua lub log nyob rau hauv tsev tsheb thauj neeg mob:
C = Yuav tsum muaj peev xwm thauj khoom ntawm casters
L = Maximum trolley load
W = Thawv nyhav
Piv txwv li, xav txog 300 lb lub laub nrog 1,800 lb load rau nws.Qhov no yuav yog 2,100 lbs.muab faib los ntawm 3. Rau qhov kev thauj khoom no, txhua lub caster yuav tsum txhawb nqa / raug ntsuas rau 700 lbs.los yog ntau dua.
Lwm yam yuav tsum tau soj ntsuam xyuas kom meej qhov tseeb caster xav tau rau daim ntawv thov, xws li: caster configuration, ambient kub, lub voj voog lub luag hauj lwm, tread khoom, thiab ceev (log nrog pob bearings yuav muaj peev xwm txo load ntawm speeds tshaj 3 mph).
