Builders' hoists for goods - Part 1: Hoists with accessible platforms

This standard deals with power operated temporarily installed builders hoists (referred to as “hoists“ in this standard) intended for use by persons who are permitted to enter sites of engineering and construction, serving landing levels, having a load carrying device: - designed for the transportation of goods only; - guided; - travelling vertically or along a path within 15 degrees max. of the vertical; - supported or sustained by drum driven wire rope, chain, rack and pinion, hydraulic jack (direct or indirect), or an expanding linkage mechanism; - where masts, when erected, may or may not require support from separate structures; - which permits the access of instructed persons during loading and unloading; - which are driven by appointed persons; - which permits, if necessary, during erection, dismantling, maintenance and inspection, the access and travel by persons who are competent and authorised. The standard identifies hazards as listed in clause 4 which arise during the various phases in the life of such equipment and describes methods for the elimination or reduction of these hazards when used as intended by the manufacturer. This standard deals with the hoist installation. It includes the base frame and base enclosure but excludes the design of any concrete, hard core, timber or other foundation arrangement. It includes the design of mast ties but excludes the design of anchorage bolts to the supporting structure. It includes the landing gates and their frames but excludes the design of any anchorage fixing bolts to the supporting structure.

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 platform and load relative to the mast and its ties, both during the vertical passage of the platform and any horizontal movement, e.g. swivelling of the platform. 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 platform and equipment which moves together with the platform. 5.2.2.2 Dead weights of the unladen platform and all equipment which moves together with the platform. 5.2.2.3 Dead weight of landing platforms and gates if supported by the hoist. 5.2.2.4 Rated load on the platform The effect of the forces on the platform 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 platform: a) If ²m/kN0,375,0xAF< 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 3,0 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 platform. One example is shown in figure 1.

²m/kN0,375,0xAF≥ then the rated load shall be assumed to be distributed over an area (A2) equivalent to 75 % of the total floor area of the platform. 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 platform. One example is shown in figure 2.

Figure 3 — 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
where
FV = vertical force [kN]
F = 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, 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 4 — One example of forces during loading and unloading 5.2.2.7 For hoists according to 5.10.2.2.5, the design of the hoist shall consider failure of the upper terminal stopping switch in combination with impact with the upper buffers both with and without load. The stalling torque and inertia of the drive system shall be taken into account. 5.2.2.8 The effect of moving loads shall be determined by taking the weight of all actual loads (platform, rated load, 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. 5.2.2.9 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. 5.2.2.10 The platform 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. 5.2.2.11 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 4302:1981" with the exception of the following: 5.2.2.11.1 Action of the wind on the platform When calculating wind pressure on the platform it shall be assumed that the platform walls and any guards 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 12158-1:2002+A1:2010

The values of out of service wind pressure are given in table 2.
