Manatua: Fl o le dynamic saogalemu mea. E tatau ona faʻaogaina e tuʻufaʻatasia ma le dynamic avega curve. E sau mai le poto masani ma faataʻitaʻiga. O le faʻatatauga taua faʻavae i luga o le maualuga o le galuega avega.

Mo se faʻataʻitaʻiga: o le partal crane diagram

O le fuafuaina metotia o le maualuga maualuga avega ua fautuaina e pei ona taua:

Before choosing the rotary support, the static safety factor fs that should be considered for the host should be determined, which can be found in schedule 1. Portal crane：fs=1.45

A o le maualuga maualuga tulaga o loʻo amanaia, o le fuafuaina faʻatulagaina o lana uta o loʻo mulimuli mai:

1) Le maualuga o le galue avega o se valu-maualuga le malosi

axal malosi ie = q + A + o + g

Overtarning taimi m = Q × lmax + a × amx + w × r - o × r - g × g

2) E tusa lava pe o le matagi malosi, mafaufau i le avega o 25% suʻega avega

axal malosi fa = 1.25 × q + a + o + g

Tiptarning taimi m = 1.25 × Q × lmax + o × amx - o × o - g ×

Faʻataʻitaʻiga: O le mamafa o le avega ma le amliture o le Clamthell Spar ua taʻua e pei ona taua:

Q = 260 BN LMAX = 23 M 1MAX = 23M

A = 75 BY AMAX = 11 M AMAX = 11m

O = 450 lute o = 0.75 m o = 0.75m

G = 900 la g = 3 m g = 3m

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

Maualuga le galue avega o le matagi malosi i le maualuga 8

Fa = q + a + o + g

= 260 + 75 + 450 + 900

= 1685 la

M = Q × lmax + o × Amax + w × r - o × o - g × g

= 260 × 23 + 75 × 11 + 27 × 6.5 × 50 × 0.75 × 900 × 900 × 900 × 900 × 900 × 900 × 900 × 900 × 900 × 900 × 900 × 10

= 3943

2) E tusa lava poʻo le a le malosi o le matagi, mafaufau i le maualuga o le galuega o le 25% suʻega avega

Fa = 1.25 × Q + A + o + g

= 325 +75 +450 +900

= 1750KN

M = 1.25 × Q × lmax + o × amx - o × o - g × g

= 325 × 23 + 70 × 11 × 45 × 0.75 × 900 × 900 × 3

= 5566.3 kolo

3) maualuga le galulue mamafa tusa lava pe o le matagi malosi

Fa = 1685 la

M = Q × lmax + a × AAAX - O × O - G × g

= 260 × 23 + 75 × 11 × 230 × 0.75 × 900 × 900 × 3

= 3767.5 la

Utaina tulaga 2 o loʻo faʻaaogaina e pei o le galuega galue o faʻamaumauga fuafuaina

E tusa ai ma le Faʻamatalaga 1, o le pa puipui (fatu pakete) e tatau ona lagolagoina e ni laina se tolu o le faʻafanua-ituaiga lagolago:

O le Static Earnit avega o Rotary lagolago o le:

O le '= 1750 la × 1.45 = 2537.5 con m' = 5566.3 bonm × 1.45 = 8071.1

O le fuafuaina o avega o le bolt o:

Fa = 1750 la m = 5566.3 kolo

E tusa ai ma le fuafuaina o loʻo i luga, o le filifilia o le tuuina atu o le faʻaaogaina o le faʻaaogaina o curve e mafai ona fuafua e filifili le vaega rotary o le 13 * .45.2000.002

O le faʻamatalaga o loʻo i luga o le faʻamatalaga auiliili metotia ofeosofiTele. E tusa ai ma le fuafuaina o taunuʻuga, e mafai ona e filifilia le talafeagaifeosofifaʻataʻitaʻiga i la matouoloa lisi. Afai e te le iloa le auala e fuafua ai, faʻamolemole lagona le saʻoloto e faʻafesoʻotaʻi ai matou i le imeli. O le a tatou auauna atu ia te oe ma le loto atoa!
