- den Blitzschutz;
- den Betrieb unter besonderen Anforderungen (z. B. in explosionsgefährdeten Bereichen);
- die elektromagnetische Verträglichkeit (Störaussendung, Störfestigkeit);

5 Safety requirements and/or measures 5.1 General The design of the hoist shall consider safe use, erection, dismantling and maintenance. It shall be possible to erect the hoist using safe access methods such as those offered by the roof of the cage or equivalent facilities. The design of all components that have to be handled during erection e.g. mast sections, shall have their weight assessed against manual handling. Where the permissible weight for manual handling is exceeded, the manufacturer shall give recommendations in the instruction handbook concerning suitable lifting equipment. !All removable and detachable covers shall be retained by captive fastenings."

EN 12159:2000+A1:2009 (E) 13 5.2 Load combinations and calculations 5.2.1 The structure of the hoist shall be designed and constructed in such a way that its strength is satisfactory under all intended operating conditions, including erection and dismantling and e.g. low temperature environments. The design of the structure as a whole and each part of it shall be based on the effects of any possible combination of loads as specified in this subclause 5.2. The load combinations shall consider the least favourable locations of the cage and load relative to the mast and its ties, both during the vertical passage of the cage and any horizontal movement of the cage. Ties between the mast and the supporting structure are considered to be part of the hoist structure. 5.2.2 When calculating the hoist structure and every related component, the following forces and loads shall be taken into account: 5.2.2.1 All dead weights with the exception of the cage and equipment which moves together with the cage. 5.2.2.2 Dead weights of the unladen cage and all equipment which moves together with the cage. 5.2.2.3 Dead weight of landing platforms and gates, if supported by the hoist. 5.2.2.4 Rated load in the cage The effect of the forces on the cage and mast resulting from the application of the rated load shall be allowed for in one of the two following ways, which reflect the chosen density of loading on the cage floor: a) if
²m/kN0,48,0xAF< where F = rated load [kN] and
A = total floor area [m²] then the rated load shall be assumed to be distributed over a reduced area (A1) which results in a distribution of 4,0 kN/m2. The format and the location of this area shall be taken as that which gives the least favourable stress for the mast and also for the cage. One example is shown in Figure 1.

²m/kN0,48,0xAF≥ then the rated load shall be assumed to be distributed over an area (A2) equivalent to 80 % of the total floor area of the cage. The format and the location of this area shall be taken as that which gives the least favourable stress for the mast and also for the cage. One example is shown in Figure 2.

See Figure 3. SIST EN 12159:2002+A1:2009

Figure 3 — Evenly distributed load case 5.2.2.6 Forces during loading and unloading (see Figure 4) 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 where
FV = vertical force [kN] F = rated load [kN] − a horizontal force FH of 20 % of the rated load, but not less than 0,5 kN and not more than 2,5 kN, both forces acting at 1/3 of the width of the cage entrance, at floor level, in the least favourable direction and location. The stresses in the mast and also in the cage shall be calculated for at least the following application points of the loading and unloading forces: − the cage 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 cage floor (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 4 — 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 (cage, rated load, counterweight, wire ropes etc.) and multiplying them by an impact factor µ = (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. A lower factor, but not less than 1,2 can be used if it can be verified by test under all conditions of loading up to 1,3 times rated load including any inertia effects of the drive system. 5.2.2.9 The cage roof, if intended to be accessible for erection, dismantling, maintenance or emergency escape, shall be designed to withstand a load of at least 3,0 kN placed on the least favourable square area of 1,0 m2. The roof shall also withstand a load of 1,2 kN applied on any area of 0,1 x 0,1 m. 5.2.2.10 The cage roof intended not to be used as support for persons shall be designed for a load of
1,0 kN applied on any point of 0,1 x 0,1 m. 5.2.2.11 The cage floor surface shall be designed to withstand without permanent deformation a static force of 1,5 kN or 25 % of the rated load, whichever is the greater, but in no case more than 3 kN, the force applied on the least favourable square area of 0,1 m x 0,1 m. 5.2.2.12 Design wind conditions The aerodynamic pressure q is given by the general equation: 6,1vq2w= where q is the pressure in N/m² and vW the wind velocity in m/s. 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 with the exception of the following: 5.2.2.12.1 Action of the wind on the cage When calculating wind pressure on the cage it shall be assumed that the cage walls 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. SIST EN 12159:2002+A1:2009
EN 12159:2000+A1:2009 (E) 17 If the design of the cage permits materials to be carried outside the cage according to 5.6.1.3.3, then an additional in service wind area shall be taken into account, at least equivalent to a solid box the plan size of the hatch extending 2 m above the cage r
