Danda guru resingle-girder bhiriji cranehaina kuenzana, iyo inokanganisa zvakananga kugadziriswa kwakazotevera. Kutanga, isu tichaita nekubwinya kwegomba tisati taenderera kune inotevera maitiro. Ipapo nguva yekusingaperi uye yekuisa nguva ichaita chena uye isina mhosva. Nekudaro, Bridge crames ine mhando dzakasiyana uye ma parameter ane akasiyana mamiriro ezvimiro zvematanda avo makuru.
Isu tinofanirwa kutanga tanzwisisa pfungwa mbiri dzinotevera nezvechigadzirwa:
1. Ndezvipi zvinhu uye zvigadzirwa zvebhodhi zvinodikanwa kuti ugadzirise danda hombe reiyo Bridge muchina (Mabhodhi, Rolls, akaumbwa-akaumbwa zvikamu, vatongi)?
2..
Parizvino, pane nzira mbiri dzekubata nekubwinya kweiyo huru danda re crane:
1. Iko kushandiswa kwehunyanzvi hwekurapa kurapa ndiko kubvisa zvikamu zvekupukunyuka
2. Makemikari Polising. Kemical polishing ndeyekuita microscopic convex zvikamu zveiyo nzvimbo yekuvhara yedata yekunyungudika yekutanga mune yemakemikari yepakati, nekudaro kuwana nzvimbo yakatsiga. Mukana wehunyanzvi wenzira iyi ndewekuti mabasa akaomarara anogona kupukutwa pasina michina yakaoma, uye mahwendefa mazhinji esimbi anogona kupukutwa panguva imwe chete. Dambudziko rine zvemakemikari polishi ndiko kushandiswa kwekupukuta kwemvura uye zvigadzirwa zvigadzirwa. Iyo yekumusoro roughness yakawanikwa nemakemikari polishing inowanzo kuve 10μm.
