Lapho kusetshenziswa i-gantry crane, kuyithuluzi lokuvikela ukuphepha elingakuvimbela ngokugcwele ngokweqile. Ibizwa nangokuthi umkhawulo wethamo lokuphakamisa. Umsebenzi wayo wokuphepha ukumisa isenzo sokuphakamisa lapho umthwalo wokuphakamisa we-crane wedlula inani elilinganiselwe, ngaleyo ndlela ugweme ukulayisha ngokweqile izingozi. Abalingani abaningi basetshenziswa kakhulu ku-Bridge Type Cranes futhi bahlanze. -NyeUhlobo lwe-Jib Tranes(isb Kunezinhlobo eziningi zemikhawulo elayishwa ngokweqile, imishini kanye ne-elekthronikhi.
.
(2) Uhlobo lwe-elekthronikhi: Yakhiwa izinzwa, ama-amplifiers asebenzayo, aphula ama-actiotors kanye nezinkomba zomthwalo. Ihlanganisa imisebenzi yezokuphepha efana nokubonisa, ukulawula kanye ne-alamu. Lapho i-crane iphakamisa umthwalo, inzwa ekwakhiweni kwezakhi zezakhi zomthwalo, iguqula isisindo somthwalo ibe isibonakaliso sikagesi, bese siyikhulisa ukukhombisa inani lomthwalo. Lapho umthwalo weqa umthwalo olinganiselwe, umthombo wamandla wendlela yokuphakanyiswa uyanqunywa, ukuze isenzo sokuphakamisa sendlela yokuphakamisa singatholwa.
Le khasigantry craneIsebenzisa isikhathi sokuphakamisa ukukhombisa isimo somthwalo. Inani lokuphakamisa lemizuzwana linqunywa ngumkhiqizo wesisindo sokuphakamisa kanye ne-amplitude. Inani le-Amplituty linqunywa ngumkhiqizo wobude bengalo ye-crane boom kanye ne-cosine ye-angle yokuthambekela. Noma ngabe i-crane igcwele ngokweqile empeleni inomkhawulo wokuphakamisa amandla, ubude be-boom kanye ne-angle yokuthambekela kwe-boom. Ngasikhathi sinye, amapharamitha amaningi anjengezimo zokusebenza nazo kufanele zibhekwe, okwenza ukulawula kuyinkimbinkimbi ngokwengeziwe.
I-Torque Ruled elawulwa kangaka esetshenziswa kakhulu ye-torque ihlanganisa izimo ezahlukahlukene futhi ixazulule le nkinga kangcono. I-torque limiter iqukethe umtshina womthwalo, umtshina wobude bengalo, umtshina we-angle, isikhethi esisebenzayo sokwehla kanye ne-microcomputer. Lapho i-crane ingena esifundazweni esisebenzayo, amasiginali wokutholwa kwepharamitha ngalinye lesifundazwe uqobo afakwa kwikhompyutha. Ngemuva kokubalwa, ukukhulisa nokucubungula, ziqhathaniswa nenani lesikhashana eligcinwe ngokuphakanyiswa, futhi amanani wangempela ahambisanayo aboniswa esibukweni. . Lapho inani langempela lifinyelela kuma-90% enani elilinganiselwe, lizothumela isiginali yokuqala yesexwayiso. Lapho inani langempela lidlula umthwalo olinganiselwe, kuzokhishwa isibonakaliso se-alamu, futhi i-crane izoyeka ukusebenza endaweni eyingozi (ukukhulisa, ukunwebisa ingalo, yehlise ingalo, nokujikeleza kwengalo, nokujikeleza).
