Where the mass/rigidity of the base does not provide inherent stability, stability is assured by stabilizers interlocked with movements of the extending structure. The movements of the extending structure are normally made by fluid power (hydraulics). The platform is self-levelling and is primarily used to carry one or more persons and any necessary equipment and/or materials. It can be fitted with one or more monitors for projecting water or other fire-fighting fluids or semi-solid materials. Controls are provided at the platform and at the base, to control movements of the extending structure. They can also control movements of the monitor(s) and of the base if it is mobile. The extended positions of the platform can be above and/or below and horizontally beyond the surface supporting the base. The extent to which hazards are covered is indicated in the scope of this document. The safety requirements of this document have been drawn up on the basis that HPs are periodically maintained by persons trained according to manufacturer's instructions, working conditions, frequency of use, and national regulations. It is also assumed that HPs are not put into operation unless all required control- and safety-devices are available and in working order and that persons operating HPs are adequately trained. When mention is made of a design for the sake of clarity, this should not be considered to be the only possible design; any other solution may be applied if it is at least equally safe. As no satisfactory explanation could be found for the dynamic factors used for stability calculations in previous national standards, the results of the tests carried out by CEN/TC 98 "Lifting Platforms" to determine a suitable factor and stability calculation method for mobile elevating work platforms (MEWPs) have been adopted. The test method is described in Annex B as a guide for manufacturers wishing to use higher or lower operating speeds and to take advantage of developments in control systems.

This clause of the document contains several requirements for the design of the safety related parts of the control system of HPs.
As the terminology is not in accordance with that of the relevant harmonised standard, EN 954-1 (see Foreword) these requirements should be interpreted on the basis of the principles of EN 954-1 pending the planned revision of this document. 5.2 Stability and structural calculations 5.2.1 General It is the manufacturer's responsibility  for stability calculations, to identify the various positions of the HP and combinations of loads, forces and removable items creating together conditions of minimum stability and  for structural calculations, to evaluate the individual loads and forces in their positions, directions and combinations producing the most unfavourable stresses in the components. NOTE It is the user's responsibility to refer other uses to the manufacturer for approval. 5.2.2 Loads and forces The following loads and forces shall be taken into account: a) Rated load; b) Structural loads; c) Wind loads; d) Manual forces; e) Additional loads and forces; f) Those resulting from operation on any residual slope; g) Those created by use of the emergency stop 5.7.7. SIST EN 1777:2005+A1:2009

1,1 × rated load (see 6.1.5.1.3). The calculated stresses shall not exceed permissible values. The calculated safety factors shall not fall below the required values. NOTE Manufacturers are recommended, by strain-gauge tests or equivalent methods of analysis, to check peak stresses under the above dynamic test conditions (see also Annex B). The permissible values of stresses and the required values of safety factors depend on the material, the load combination and the calculation method. For the design of hydraulic cylinders see 5.11. 5.2.5.2.2 Analysis a) The general stress analysis The general stress analysis is the proof against failure by yielding or fracturing. The analysis shall be made for all load bearing components and joints. b) Elastic stability analysis The elastic stability analysis is the proof against failure by elastic instability (e.g. buckling, crippling). The analysis shall be made for all load bearing components subjected to compressive loads. c) Fatigue stress analysis SIST EN 1777:2005+A1:2009

Mechanical means shall be provided to prevent uncontrolled movements of the stabilizers from the transport position. The stabilizers shall be locked in the transport position by two separate locking devices for each stabilizer, at least one of which operates automatically, e.g. a gravity locking pin plus a detent. Powered stabilizers meeting the requirements of 5.11 meet this requirement Verification: by design check and functional test. 5.3.6 For HPs with stabilizers for levelling the extending structure these shall be capable of levelling it within the maximum residual slope when operating on the maximum slope specified by the manufacturer. Verification: by functional test. NOTE The normally accepted supporting surface variations within which HPs for general fire service use may be operated without restriction are:
 longitudinal and transverse slopes, up to 7 °;  depressions, up to 50 mm;  humps (kerbs, etc.), up to 150 mm. 5.3.7 The movements of stabilizers shall be limited by mechanical stops. These stops shall be of sufficient strength to absorb the maximum force exerted. The ends of hydraulic cylinders, if properly constructed for the purpose, fulfil this requirement. Verification: by design check. 5.3.8 Any stabilizer feet shall be constructed to accommodate ground unevenness of at least 15 ° in any direction. Verification: by visual examination and measurement. 5.3.9 Vehicle mounted HPs shall be equipped with an indicator visible to the driver to indicate if the HP is not in its transport condition. Verification: by functional test. 5.3.10 Vehicle mounted HPs shall comply with all of the noise reduction requirements of EN 1846-2. 5.3.11 HPs which are operated in public traffic areas shall satisfy the national road traffic and lighting regulations. Verification: by visual examination. 5.3.12 Group 3 HPs shall be equipped with brakes or other stopping devices which engage automatically when power is removed or fails, and remain effective if any one wheel lifts clear of the supporting surface due to operation of the extending structure or travelling. After being engaged, the brakes shall not depend on an exhaustible energy source. SIST EN 1777:2005+A1:2009
