Isakhiwo sesakhelo sesithuba esisicaba segadi yezityalo inobude obupheleleyo obuziimitha ezingama-30, ubude bubonke buziimitha ezingama-35.4 kunye nobude obuziimitha ezingama-155.
1. Uhlobo lwesakhiwo sentsimbi yendawo yentsimbi: isakhelo sendawo yentsimbi yesicaba, inkxaso ye-chord ephantsi.
2. Ixesha lokubhekisela kuyilo lwesakhiwo yiminyaka engama-50, ubomi benkonzo yoyilo lwesakhiwo: iminyaka engama-50;inqanaba lokhuseleko lwesakhiwo: Udidi II.
3. Ukuqina kwe-Seismic fortification: i-7 degrees, iqela lesibini lamaqela enyikima, isiseko soyilo lwe-seismic acceleration: 0.15g.Udidi lwe-Seismic fortification: udidi olusemgangathweni lwezokhuselo.
4. Lo mqulu kufuneka wakhiwe ngokubambisana ne "Basic Drawing of Closed Grid Frame of the Car Uloading Ditch" (T0202) kunye "noMzobo weSakhiwo soMzobo wokuThuthulwa kweMoto ovalelweyo" (T0204).
5. Umbhobho wensimbi wesakhelo segridi: umbhobho we-welded we-high-frequency (iintonga ezingaphantsi kwe-φ114, zingabandakanyi), iipayipi zensimbi ezingenamthungo (iintonga ze-φ114 nangaphezulu);izinto eziphathekayo: I-Q235B, intsimbi kufuneka ihlangabezane nomgangatho wesizwe "i-low-alloy high-strength structural steel" GB/ T1591;
Kwaye kufuneka ihlangabezane neemfuno zemathiriyeli "zeSteel Structure".
6. Ibhola yebholiti: Yenziwe ngeNombolo ye-45 yensimbi "kwi-High Quality Carbon Structural Steel" (GB / T 699) ngokutshisa okutshisayo, emva koko kusetyenzwa.
Umphezulu kufuneka ube mpuluswa, kungabikho zintanda, kungabikho ukutshisa, kungabikho pitting.Umsonto kufuneka uhambelane neemfuno zemisonto eqhelekileyo kwi-"Basic Dimensions of Ordinary Threads" (GB/T 196), kwaye i-thread tolerances kufuneka ibe yibakala 6H njengoko kucacisiwe kwi-"Ordinary Thread Tolerances" (GB/T 197).
Ifom kunye nobukhulu beebholithi kufuneka zihlangabezane neemfuno zomgangatho welizwe langoku "Iibholiti eziphezulu zokuqina kweentsimbi zegridi kunye neebhola zebhola" (GB / T 16939).
