Ngwá ọrụ backhoe loaders

Ngwaọrụ backhoe loaders bụ igwe na-arụ ọrụ, nke nwere wheels ma ọ bụ tracks, nke nwere bucket loader nke etiti na arm excavator nke azụ nwere bucket articulated. Na nkọwa nke injinia ntọala miri emi na mgbidi ala, backhoe loaders na-arụ ọrụ dị ka akụrụngwa nkwado dị mkpa na-akwado ọrụ owuwu bụ isi nke mgbidi diaphragm, mkpuchi mkpuchi, secant na tangent pile arrays, mgbidi sheet pile, na itinye jet grouting. Ngwaọrụ ndị a anaghị arụ ọrụ ntọala bụ isi kama na-enye nkwado dị mkpa na logistics, ịkụ, na ijikwa ihe nke na-eme ka arụ ọrụ nke ọrụ ntọala pụrụ iche dị irè. Backhoe loaders na-eji na ọtụtụ usoro nke owuwu mgbidi ala. N'oge nkwadebe saịtị, ha na-ehichapụ ma na-edozi pits ntọala, na-ahụ maka ịchekwa ihe efu na ala a na-ewe, na-akwadebe ụzọ maka igwe drilling na pile driving dị arọ. N'oge owuwu na-arụ ọrụ, ha na-ahụ maka mmegharị ihe buru ibu gụnyere nkwadebe na nkesa bentonite slurry, mbupu nke cages nkwado ígwè, mmegharị nke casing drilling na pipes, na iwepụ ihe efu na-aga n'ihu site na trenches mgbidi diaphragm ma ọ bụ excavations mkpuchi mkpuchi. Arm excavator nke azụ na-enye ohere maka itinye ihe na iwepụ na mpaghara ọrụ nke nwere oke, ebe loader etiti na-enye ikike ijikwa ihe buru ibu, na-eme ka backhoe loaders bụrụ ihe dị mkpa na saịtị nwere oke ohere ma ọ bụ usoro multi-layer dị mgbagwoju anya ebe mmegharị ihe n'usoro bụ ihe dị mkpa. Usoro arụmọrụ na-ejikọta usoro hydraulic abụọ dị iche: hydraulics loader na-enye lifting na njikwa bucket maka ọrụ etiti, ebe hydraulics backhoe na-arụ ọrụ arm, swing mechanism, na bucket azụ n'ụzọ dị iche. Nke a na-enye ohere ka ndị na-arụ ọrụ mee loading, digging, na nkewa ihe n'usoro. Na saịtị mgbidi diaphragm, backhoe loaders na-ahụ maka clay ma ọ bụ sand slurry nke na-akwado mgbidi trench, na-maintain stockpiles efu, na ijikwa volumu ala a na-ewepụ. Maka itinye mkpuchi mkpuchi na-eji usoro jet grouting, igwe ndị a na-etinye ma na-emegharị containers slurry grouting na ijikwa cement admixtures. Usoro tangent na secant pile na-erite uru na njikwa bucket ziri ezi nke backhoe loaders maka excavation pile cap na ijikwa casing. Ndị dị na nhazi gụnyere loaders wheeled rigid-frame nwere ibu ọrụ nke atọ ruo anọ-tonne, nke kwesịrị ekwesị maka ụzọ dị mma na ikpo okwu kwadebere, na ụdị track nwere nrụgide ala belatara (0.4–0.8 MPa) nke a na-emezigharị maka ala dị nro, mmiri ma ọ bụ nke a na-emebi. Ikike bucket na-adịkarị site na 0.1 ruo 0.35 cubic meters, na ịdị elu nke ịkụ site na 4 ruo 5.5 mita. Ngwaọrụ pụrụ iche gụnyere grapple buckets maka ijikwa nkwado, magnetic plates maka ịnapụta ígwè, na usoro quick-coupler na-enye ohere maka mgbanwe ngwa ngwa. Nhọrọ nke atụmatụ gụnyere ikike ala saịtị na ohere ọrụ dị, volumu ihe achọrọ na ọnụego ijikwa, ọnọdụ ala na oge (oge mmiri na oge oyi na-achọ ụdị track), nkwado na usoro drainage saịtị na ijikwa slurry, na ikike ndị na-arụ ọrụ. Ọnụ ahịa mbupu, iji mmanụ, na nkwado mmezi n'ime mpaghara bụ ihe ndị ọzọ nke akụ na ụba. Ụkpụrụ mba ụwa ISO 6165 (nchịkọta igwe na-emegharị ala), ISO 11001 (ihe achọrọ nchekwa), na iwu akụrụngwa mpaghara (2006/42/EC) na-achịkwa imewe na ọrụ, n'agbanyeghị na backhoe loaders na-apụghị ịhụkarị na ụkpụrụ ntọala (EN 14104, DIN 4123) nke na-elekwasị anya na akụrụngwa owuwu bụ isi.
