See Figure 4.
Figure 4 — Evenly distributed load case 5.2.2.6 Forces during loading and unloading shall be considered as the concurrent effect of a vertical force and a horizontal force, each calculated as follows: — a vertical force FV of 50 % of the rated load but not less than 2,0 kN, or, for rated loads greater than 20 kN, calculated from the equation: FV = 4 + 0,3 F SIST EN 16719:2018

is the rated load [kN]
— a horizontal force FH of 15 % of the rated load, but not less than 0,3 kN and not more than 2,5 kN (lower horizontal forces may be used if the designer can demonstrate by calculation and/or testing that such lower forces can be justified) both forces acting at 1/3 of the width of the platform entrance, at floor level, in the least favourable direction and location. The stresses in the mast and also in the platform shall be calculated for at least the following application points of the loading and unloading forces: — the platform threshold; — the leading edge of any ramp or other extension, which is not supported by the landing. At the same time any remaining part of the rated load shall be applied in the centre of the platform (FV1). Equivalent forces shall be used to design the landing threshold and all relevant supporting structures. Information shall be given in the instruction handbook with regard to these forces.
Figure 5 — One example of forces during loading and unloading 5.2.2.7 The effect of moving loads shall be determined by taking the weight of all actual loads (platform, rated load etc.) and multiplying them by an impact fac = (1,1 + 0,264v) where v is the rated speed in m/s. Alternative factors may be used if they can be proved to be more accurate. 5.2.2.8 To determine the forces produced by an operation of the overspeed safety device, the sum total of the travelling load shall be multiplied by the factor 2,5. SIST EN 16719:2018
In all cases it shall be assumed that the wind can blow horizontally in any direction and the least favourable direction shall be taken into account. The calculation shall be done according to ISO 4302:2016 with the exception of the following: 5.2.2.10.2 Action of the wind on the platform When calculating wind pressure on the platform it shall be assumed that the platform sides and any guards, including the overhead fall protection structure, are solid and an aerodynamic coefficient of c = 1,2 shall be applied. The factor 1,2 covers both the shape factor and the shielding factor. The full area of one person shall be 0,7 m2 (0,4 m average width x 1,75 m height) with the centre of area 1,0 m above the platform floor, with a shape factor of 1,0. The wind area of persons above imperforate platform sides shall be calculated using an area of 0,35 m2 with the centre of area 1,45 m above the platform floor. The number of persons directly exposed to the wind shall be calculated as a) the length of the side of the platform exposed to the wind, rounded to the nearest 0,5 m, and divided by 0,5 m, or b) the number of persons allowed on the platform if less than the number calculated in a), c) if the number of persons allowed on the platform is greater than in a) a shape factor of 0,6 shall be applied to the extra number of persons.

is the safety factor on yield strength
b) Calculations according to the theory of the second order The deflection of a structure shall be taken into account when calculating stresses. This is very important when calculating a slender design or using materials with a low modulus of elasticity. This can be done by using the theory of the 2nd order. yyoSf=σ=or=yySf' where fy’
is the apparent yield strength [N/mm2].
The safety factors against fy and fy’ shall be at least equal to those given in the following Table 4 - Safety factors for steel structures, which is related to Table 6 - load cases. Table 4 — Safety factors for steel structures Load Case Safety Factor (Sy) A 1,5 B 1,33 C 1,25 5.2.3.2 Aluminium structures a) Permissible stresses yyoSf=σor=uuSf whichever gives the lowest value where fu
is the tensile strength [N/mm2]; Su
is the safety factor on tensile strength. SIST EN 16719:2018
