I luga o le mataupu faavae, o le uta maualuga maualuga e leslewing bearinge tatau ona fa'aogaina le lagolago e fai ma tau fa'atatau, lea e tatau ona aofia ai le uta fa'aopoopo ma le uta su'ega.

E le o aofia ai i le talosaga i le laulau, o le static safety factor fs e mafai ona filifilia e ala i le faʻasino i tulaga faigaluega tutusa ma talosaga i le laulau.

Ole metotia fa'atatau ole uta maualuga e fautuaina e fa'apea:

A'o le'i filifilia le lagolago fa'ata'amilo, e tatau ona fa'amautu le tulaga saogalemu fs e tatau ona mafaufauina mo le talimalo, lea e mafai ona maua i le fa'asologa 1. Portal crane:fs=1.45

A iloa le maualuga maualuga o le uta, o le fua fa'atatau o lona uta e fa'apea:

1) le maualuga o le avega galue o se malosi matagi valu tulaga

malosi axial Fa = Q + A + O + G

taimi liliu M = Q × lmax + A × amax + W × r – O × o – G × g

2) E tusa lava po o le a le malosi o le matagi, mafaufau i le uta o le 25% suʻega uta

malosi axial Fa = 1.25 × Q + A + O + G

taimi liliu M = 1.25 × Q × lmax + A × amax – O × o – G ×

Fa'ata'ita'iga: o le uta galue ma le tele o se uafu clamshell e iloa e fa'apea:

Q = 260 kN lmax = 23 m 1max=23m

A = 75 kN maualuga = 11 m maualuga = 11m

O = 450 kN o = 0.75 m o=0.75m

G = 900 kN g = 3 m g=3m

W = 27 kN r = 6.5 m1) r=6.5m

Tulaga maualuga o le malosi o le matagi ile tulaga 8

Fa = Q + A + O + G

=260 + 75 + 450 + 900

=1685 kN

M = Q×lmax + A×amax + W×r – O × o – G× g

=260 × 23 + 75 × 11 + 27 ×6.5×450 ×0.75×900 × 3

= 3943 knm

2) e tusa lava po o le a le malosi o le matagi, mafaufau i le maualuga o le galuega mamafa o le 25% suʻega uta

Fa = 1.25×Q + A + O + G

=325 +75 +450 +900

= 1750kN

M = 1.25×Q×lmax + A×amax – O×o – G×g

= 325 × 23 + 75 × 11 × 45 × 0.75 × 900 × 3

= 5566.3 knm

3) maualuga galuega mamafa e tusa lava po o le a le malosi o le matagi

Fa = 1685 kN

M = Q×lmax + A×amax – O×o – G×g

= 260 × 23 + 75 × 11 × 450 × 0.75 × 900 × 3

= 3767.5 knm

Tulaga uta 2 o loʻo faʻaaogaina e fai ma avega galue o le faʻatusatusaga faʻapitoa

E tusa ai ma le fa'asologa 1, e tatau ona lagolagoina le va'a (grab bucket) i laina e tolu o le roller-type rotary support:

O le uta fa'asinotonu o le lagolago rotary o le:

Fa' = 1750 kN × 1.45 = 2537.5 kN M'= 5566.3 kNm × 1.45 = 8071.1 kNm

Ole fua fa'atatau ole fa'amau ole:

Fa = 1750 kN M = 5566.3 kNm

E tusa ai ma le faʻatusatusaga o loʻo i luga, o le filifiliga o le faʻaogaina o le gafatia e mafai ona fuafua e filifili le lagolago rotary o le 13 * .45.2000.002

O le faʻamatalaga o loʻo i luga o le auala faʻatusatusa auiliili oslewing bearingtele.E tusa ai ma taunuuga o le faʻatusatusaga, e mafai ona e filifilia le mea talafeagaislewing bearingfa'ata'ita'iga i la tatoufa'amaumauga o oloa.Afai e te le iloa pe faʻafefea ona faʻatatau, faʻamolemole lagona le saoloto e faʻafesoʻotaʻi matou ile imeli.O le a matou auauna atu ia te oe ma le loto atoa!
