The excavator boom cast steel seat is acore heavy{{0}duty hinged cast cast steel partchemudziyo wekushanda wekuchera. Iyo yakabatanidzwa yakakandwa uye inonyanya kusungirirwa uye yakaunganidzwa kune iyo huru muviri weiyo yekuchera boom. Inoshanda sekiyi yekuremerwa-inotakura hwaro hwekubatanidza hinge yemaboom pin shafts, hydraulic cylinders nema arm links, inoshingirira kushanda, kuchinjanisa mitoro uye torsional mitoro.
Iyo inogadzirwa kubva muinjiniya kabhoni cast simbi, ine inowanzoshandiswa nyika standard mamakisiZG230-450uyeZG270-500.
Iwo akaenzana eEuropean neAmerican standard mamakisi ndeaya anotevera:
European Standard: GP240GH, C25 engineering carbon cast steel
American Standard: ASTM A216 WCB carbon cast simbi (inonyanya kushandiswa yakaenzana giredhi)
The material featureskusimba kwepamusoro, kusimba kwakanaka, kusimba kwakanyanya, kusimba kukuru kwekurwisa uye kuramba kuneta, kunyatsoenderana ne-saiti welding mamiriro ebhoom. Mushure me normalizing / annealing kupisa kurapwa, iyo yemukati microstructure yakaoma, isina hurema hunokuvadza senge shrinkage cavities, porosity uye makatsemuka.
Iyo yakakosha yekukanda chimiro inotsiva yakagadzirwa neplate welding, inoratidzira yunifomu yekushushikana kugovera uye yakakwirira kuramba kuputika uye deformation. Inoenderana nemamiriro ekushanda akanyanya semigodhi, kugadzirwa kwevhu uye inorema-nzvimbo dzekuvakisa dzinorema dzevacheri vematani ese, uye inoshanda sechikamu chakakosha chekuchengetedza zvimiro uye kuwedzera kwehupenyu hwesevhisi yekuchera.
