1. Tšebeliso ea ho Phahamisa Frame ea tšepe (Hoisting Calculation)

I. Setšoantšo sa Phahamiso

Setho:Beam ea tšepe H500×200×10×16, Length L = 12.0 m

Lintlha tsa Phahamiso:Beha L / 4 ho tloha pheletsong e 'ngoe le e' ngoe ea leballo

Sling Angle:α ≈ 60°

II. Phallo Calculation

1. Boima ba Boima ba Beam:
G = ρ × V = 78.5 kN/m³ × 0.212 m³/m × 12.0 m = 199.9 kN

2. Dynamic Load Factor:Nka 1.1

3. Boima ba Marang-rang:E hlokomolohuoe (ha e na thuso)

4. Kakaretso ea Mojaro o Phahamisang:
P = G × 1.1 = 219,9 kN

5. Tension ea Sling (Moroalo o leka-lekaneng):
T = P / (2 × cos α) = 219.9 / (2 × cos 60°) = 219.9 kN

III. Sling Safety Check

1. Mofuta oa Sling:φ20 thapo ea tšepe ea tšepe, mojaro o robehileng Fb = 360 kN

2. Ntlha ea Tšireletseho (n):
n = Fb / T = 360 / 219.9 = 1.64 > 1.25
