Sliding capacities

Calculation for Chain no. 1

Longitudinal capacity = fx * (MSL / SafetyFactor)

fy = Friction * Sin(VSA) + Cos(VSA) * Cos(HSA)

Transverse capacity = fy * (MSL / SafetyFactor)

fx = Friction * Sin(VSA) + Cos(VSA) * Sin(HSA)

Note:


When HSA = 90, the transverse capacity is not assigned.

= 4.60 m

= 7.21 m

= 0.9 * (100.00 / 1.35) * 1.22 = 81.1 kNm

= 1.29 * Sin(Atan(Tan(61) / Cos(-50))) m

= 0.9 * (100.00 / 1.35) * 0.00 = 0.0 kNm

= 8.50 - 7.21 m

= 0.9 * (100.00 / 1.35) * 4.24 = 282.4 kNm

= 0.00 * Sin(Atan(Tan(61) / Cos(40))) m

= 4.50 - 4.60 m

= 4.60 * Sin(Atan(Tan(61) / Cos(40))) m

When the calculated HSD for a side is negative, it will be reduced to 0.

CargoWidth for (transverse tipping) and CargoLength (for longitudinal tipping) can be evaluated from CargoWidth, CargoLength, Bcargo or Lcargo, depending on the shape and rotation of the cargo.

Calculation for Chain no. 1

= 0.634 * (100.0 / 1.35) = 46.9 kN

= 0.574 * (100.0 / 1.35) = 42.5 kN

= 0.3 * Sin(Abs(61)) + Cos(Abs(61)) * Sin(Abs(40))

= 0.3 * Sin(Abs(61)) + Cos(Abs(61)) * Cos(Abs(40))

When HSA = 0, the longitudinal capacity is not assigned.


Cws = (Cwss / sf) / (Sqrt(Z1 + Z2))

Z2 = (3 / Pow(Wa, 2))

Z1 = (Pow(h, 2) / Pow(W, 2))

Bws = (W * Bwss / sf) / h

Sws = Wa * Swss / sf

W = Wa * L / 6

= (15.7 / 1.50) / (Sqrt(0.00002 + 0.00033)) = 176.6 kN

= (3 / Pow(300.0, 2)) = 0.00333

= (Pow(2.0, 2) / Pow(150.0, 2)) = 0.00018

= (150.0 * 13.7 / 1.50) / 2.0 = 685.0 kN

= 30.0 * 8.3 / 1.50 = 166.0 kN

= 30.0 * 30.0 / 6 = 150.0 cm³
