EN 12158-2:2000+A1:2010 (E) 4 Introduction This standard is one of a series of standards produced by CEN/TC 10/SC 1 as part of the CEN programme of work to produce machinery safety standards. The standard is a Type C standard relating to safety for builders hoists for goods. The extent to which hazards are covered is indicated in the scope of this standard. In addition, machinery should comply as appropriate with !EN ISO 12100:2003" for hazards which are not covered by this standard. !When provisions of this type C standard are different from those which are stated in type A or B standards, the provisions of this type C standard take precedence over the provisions of the other standards, for machines that have been designed and built according to the provisions of this type C standard. The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indicated in the scope of this European Standard." 1 Scope 1.1 This standard deals with power operated temporarily installed builders hoists intended for use by persons who are permitted to enter sites of engineering and construction, serving either one upper landing or a work area extending to the end of the guides, (e.g. a roof) having a load carrying device (lcd):  which is intended for the transportation of goods only;  where it is forbidden for persons to step upon it at any time;  which is guided;  which is designed to travel at an angle of at least 30 degrees to the vertical but may be used at any angle between the vertical and the maximum inclination as specified by the manufacturer;  which is sustained by steel wire rope and a positive drive system;  which is controlled by hold-to-run controls by the operator;  which does not benefit from the use of any counterweight;  which has a maximum rated load of 300 kg;  which has a maximum speed of 1,00 m/s; and where the guides require support from separate structures. SIST EN 12158-2:2002+A1:2010



EN 12158-2:2000+A1:2010 (E) 5 1.2 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. 1.3 This European standard does not specify the additional requirements for:  operation in severe conditions (e.g. extreme climates, strong magnetic fields);  lightning protection;  operation subject to special rules (e.g. potentially explosive atmospheres);  electromagnetic compatibility (emission, immunity);  handling of loads the nature of which could lead to dangerous situations (e.g. molten metal, acids/bases, radiating materials, fragile loads);  the use of combustion engines;  the use of remote controls;  hazards occurring during manufacture;  hazards occurring as a result of mobility;  hazards occurring as a result of being erected over a public road;  earthquakes;  noise. 1.4 This standard is not applicable to  permanently installed lifts;  builders hoists for persons and materials;  builders hoists for the transport of goods with accessible platforms;  builders hoists with an lcd driven by hydraulic jack (directly or indirectly);  furniture hoists;  conveyors;  work cages suspended from lifting appliances;  work platforms carried on the forks of fork trucks;  work platforms;  funiculars;  lifts specially designed for military purposes;  mine lifts; SIST EN 12158-2:2002+A1:2010

5 Safety requirements and/or measures 5.1 General The design of the hoist shall consider safe use, frequent erection and dismantling as well as maintenance and transportation. At least an ambient temperature range between – 5 °C and + 40 °C shall be taken into account for correct operation. The design of all components that have to be handled during erection e.g. guide rail 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. !All removable and detachable covers shall be retained by captive fastenings." 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 as intended by the manufacturer. 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 5.2. The load combinations shall consider the least favourable locations of the lcd and load relative to the guide rails and its support, both during the passage of the lcd and SIST EN 12158-2:2002+A1:2010



EN 12158-2:2000+A1:2010 (E) 11 any movement, e.g. tilting of the lcd. The whole range of possible inclinations, as intended by the manufacturer, shall be considered. The guide rail support is 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 exception of the lcd and equipment which moves together with the lcd. 5.2.2.2 Dead weights of the unladen lcd and all equipment which moves together with the lcd. 5.2.2.3 Rated load on the lcd. The rated load shall be considered to act off centre, either side, by an amount which is equivalent to 10 % of the width (W) of the LCD (25 %, when the lcd is intended to be used with overhanging loads) (See Figure 1). Special arrangements for specific materials may need other load configurations.
Key X = 10 % W or 25 % W – see 5.2.2.3 Figure 1 — Rated load acting off centre 5.2.2.4 For calculation purposes a load of at least 3 kN/m² shall be considered as being placed over the area of the lcd, defined as the area, which supports the load at right angles to the guide rails. 5.2.2.5 Where the hoist is designed such that the lcd is driven against the end of the guide rails before the terminal stopping switch is actuated, it shall be designed to tolerate being driven against the end of the guide rails at rated speed with and without rated load (See also 5.5.1.8). The stalling torque and inertia of the drive system shall be taken into account. 5.2.2.6 The effect of moving loads shall be determined by taking the weight of all actual loads (lcd, rated load, wire ropes, etc.) and multiplying them by an impact factor µ = (1,1 + 0,264v) where v is the hoisting speed in m/s. Alternative factors may be used if they can be proved to be more accurate. 5.2.2.7 To determine the forces produced by an operation of the broken rope device, the sum total of the moving load shall be multiplied by the factor 2,5. Alternative factors, but not less than 1,2, may be used if they can be verified under all conditions of loading up to 1,25 times rated load. 5.2.2.8 Design wind conditions The aerodynamic pressure q is given by the general equation: SIST EN 12158-2:2002+A1:2010



EN 12158-2:2000+A1:2010 (E) 12 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: 5.2.2.8.1 Action of the wind on the lcd When calculating wind load on the lcd and its designed load (e.g. sheets of 1,2 m x 2,5 m) it shall be assumed that this area is solid and a factor of 1,2 shall be applied. The factor 1,2 covers both the shape factor and the shielding factor. 5.2.2.8.2 Wind pressure Three design wind conditions shall be taken into account when calculating wind pressure on hoists: 5.2.2.8.2.1 In service wind Irrespective of height, the minimum value for wind pressure shall be q = 100 N/m², corresponding to a wind velocity of vW = 12,5 m/s. 5.2.2.8.2.2 Out of service wind Out of service wind pressures depend on the height above ground and the area where the hoist is installed. The values of out of service wind pressure are given in table 3. The minimum design wind pressures shall be taken into account. Table 3 — Minimum design wind pressures Height H of parts of hoist above ground level Wind pressure q for geographical Regions

To determine the number of stress cycles, the manufacturer shall take the following into account:  15.000 movements upwards with 75 % of the maximum rated load on the lcd;  15.000 movements downwards with empty lcd;  For the calculation of the drives a travel length of 10 m for each movement (acceleration from rest to rated speed – travel at rated speed – deceleration to full stop) shall be taken into account (see also 7.1.2.11). NOTE The number of movements for a goods hoist is based on: 3 x 104 - intermittent duty (e.g. 10 years, 20 weeks per year, 25 hours per week, 6 movements per hour). 5.2.6.2 Each shaft shall possess a minimum safety factor of 2,0 against the appropriate endurance limit, under consideration of the actual notch
