Crane rails, Cov tsheb ciav hlau ciav hlau thiab cov xwm txheej hlau. Sab saum toj ntawm txoj kev tsheb ciav hlau yog convex, thiab hauv qab yog ib phaj nrog ib qho dav, uas nce qhov kev sib ze nrog lub hauv paus. Qhov hla hla ntawm txoj kev tsheb yog feem ntau zigzag, nrog cov khoom siv zoo li qub. Square steel tuaj yeem suav tias yog lub tiaj tiaj sab saum toj, vim tias ntawm cov kev hnav loj loj, feem ntau yog siv rau qhov hnyav me, qeeb nrawm, cov haujlwm tsawg dua crane.
Kev sib txuas hlau hlau feem ntau feem ntau muaj cov pa roj carbon thiab manganese steel (c {}}% ~}}% ~ 115%). Cov khoom siv raug ntawm Crane khiav yogU71mnHlau.
| Qib hlau | C(%) | Si | Mn | Cr | V | P | S | Tensile Lub Zog (RM / MPA) |
| U71mn | 0.65~0.76 | 0.15~0.58 | 0.70~1.40 | – | – | Tsawg dua los yog sib npaug rau 0.035 | Tsawg dua los yog sib npaug rau 0.030 | Ntau dua los yog sib npaug rau 880 |
Ntev ntawm Q Crane Rail
- Tus qauv ntev ntawm kev tsheb nqaj hlau yog9, 9.5, 10, 11, 11.5, 12, lossis 12.5m.
- Ib qho piv txwv ntawm cov kev sib txawv ntawm qhov loj ntawm cov nqaj uas muaj 4m mus rau 8.9m ntev tau muab rau cov tog neeg ua haujlwm tau txais kev pom zoo thiab nco ntsoov nws hauv daim ntawv cog lus. Thaum xam qhov hnyav ntawm cov ntsia hlau, txhim kho txhua txhua 100 hli.
- Qhov kev pub muaj kev tso cai ntawm cov tsheb nqaj ntev yog ± 500 hli.
