Lub lim tiam no, peb lub rooj cob qhia ntau lawm ua tiav qhov kev ua tiav, sib dhos, thiab kev tshuaj xyuas tag nrho ntawm lwm pawg ntawm siab - lub zog crane pulleys. Txhua tus tau dhau qhov kev tshuaj xyuas qhov ntev, kev ntsuas qhov ntsuas qhov ntsuas, thiab kev kho qhov chaw tiv thaiv, thiab npaj tau ntim thiab xa mus rau cov neeg siv khoom txawv teb chaws. Cov batch no suav nrog ntau yam kev qhia tshwj xeeb ntawm ib leeg rub, ob lub rubeys, thiab kev cai- ua qauv, txhua yam ua los ntawm siab- cov hlau alloy zoo kom ntseeg tau zoo dua hnav tsis kam thiab ruaj khov hauv cov khoom hnyav.
Txhawm rau kom muaj kev nyab xeeb ntev - kev thauj mus los nyob deb, cov pulleys tau dhau los tiv thaiv xeb thiab ntxiv dag zog rau cov ntoo crates. Maxwell ua raws li kev tswj hwm nruj thiab nyob ntawm - lub sijhawm xa khoom, muab cov khoom siv crane txhim khu kev qha rau cov neeg siv khoom thoob ntiaj teb.
Yog xav paub ntxiv txog kev sib tw, hooks, couplings, thiab lwm yam khoom siv crane, thov koj xav tiv tauj peb rau ib nqe lus.
