Plaub-txoj hlua rub yog tsuas yog siv ua ke nrog tus choj lossis gantry cranes. Nws yog txawm peem rau nrog ob pawg ntawm drums mus lob ntau yam xoob deposits rau loading thiab unloading, stacking thiab loading hauj lwm.
1. Cov qauv ntawm plaub txoj hlua rub:
Cov hlua khi yog tsim los ntawm kev txhawb nqa pas nrig, lub puab tsaig phaj thiab ib lub nqaj thauj khoom.
2. Lub hauv paus ntsiab lus ua haujlwm ntawm plaub txoj hlua rub:
Qhov chaw thau khoom ntawm plaub txoj hlua rub yog tswj los ntawm kev nqa hlau hlua nruas thiab qhib thiab kaw hlua hlua nruas ntawm cov khoom nqa nqa. Ob lub galvanized steel hlau ropes raug mob ntawm lub lifting hlau hlua nruas yog tsau rau ntawm wedge plhaub nyob rau sab saum toj ntawm lub taub hau. Lub plhaub plhaub yog hinged rau saum lub taub hau. Thaum lub lifting hlau hlua nruas rotates, galvanized steel hlau hlua thawb lub lob nce thiab nqis los ntawm lub plhaub wedge; ob lub galvanized steel hlau ropes raug mob ntawm qhov qhib thiab kaw hlau hlua nruas yog qhov txhab ntawm sab saum toj ntawm lub taub hau rub thiab txav rub lub rub tawm ntawm cov nqaj hlau thauj khoom los ntawm kev taw qhia lub log los tswj qhov qhib thiab kaw ntawm qhov rub.
3. Plaub-rope grab chaw ua haujlwm:
Thaum thauj khoom, qhov rub tau qis dua rau cov khoom siv hauv lub xeev txuas ntxiv (qhov qhib thiab kaw cov hlua hlau nruas tsis txav lub sijhawm no), thiab qhov qhib thiab kaw hlua hlua nruas yog pib nyob rau hauv txoj hauj lwm nqa (lub lifting hlua ua. tsis txav). Hauv qab qhov hnyav ntawm qhov rub, lub puab tsaig phaj ntawm lub rub khawb rau hauv cov khoom. Tom qab qhov rub tau kaw tag lawm, lub tshuab nqa hlau hlua nruas thiab qhov qhib thiab kaw hlua hlua nruas tau pib tib lub sijhawm los tsa cov khoom thauj mus rau qhov siab. Cov cuab yeej nqa tau pib txav lub rub mus rau qhov chaw thau khoom, thiab qhib thiab kaw cov hlua hlau nruas yog pib nyob rau hauv txoj hauj lwm qis (lub lifting hlau hlua nruas tsis txav), thiab lub rub yog qhib rau unload cov khoom.
