Introduction
The abbreviation GSE means a complete item of aircraft ground support equipment in the context of this
document.
When compiling this document, it was assumed that:
a) components without specific requirements are:
1) designed in accordance with good engineering practice and calculation codes;
2) of sound mechanical and electrical construction;
3) made of materials with adequate strength and of suitable quality;
4) made of materials free of defects;
b) components are kept in good repair and working order, so that the required characteristics remain
despite wear;
c) by design of the load bearing elements, a safe operation of the machine is ensured for loading ranges
from zero to 100 % of the rated possibilities and during tests;
d) a negotiation took place between the user and the manufacturer concerning particular conditions for
the use and places of use of the GSE;
e) the place of operation allows a safe use of GSE.
The extent to which hazards are covered is indicated in the scope of this document.
The minimum essential criteria are considered to be of primary importance in providing safe, economical
and usable GSE. Deviation from the recommended methods and conditions should occur only after careful
consideration, extensive testing and thorough in-service evaluation have shown alternative methods or
conditions to be satisfactory. Such deviations are outside the scope of this document and a manufacturer
should be able to demonstrate an equivalent level of protection.
This European Standard is a Type C standard as defined in EN ISO 12100:2010.
The machinery concerned and the extent to which hazards, hazardous situations or hazardous events are
covered are indicated in the Scope of this document.
When requirements of this type C standard are different from those which are stated in type A or type B
standards, the requirements of this type C standard take precedence over the requirements of the other
standards for machines that have been designed and built according to the requirements of this type C
standard.
1 Scope
This document specifies the conditions to be taken into consideration when calculating the strength and
the stability of GSE. It also specifies general test methods.
This part of EN 1915 is intended to be used in conjunction with EN 1915-1:2023, EN ISO 31915-3:2026
(for self-propelled GSE) and EN 1915-4:2004+A1:2009, and with the relevant part of EN 12312 to give
the requirements for the types of GSE within the scope of EN 12312.
When EN 12312 does not contain a relevant part for a GSE, EN 1915 (all parts) gives general
requirements that may apply, although additional machine specific requirements, to be determined by
the manufacturer, are likely to be required.
NOTE The methods given in this document demonstrate one way of achieving an acceptable safety level.
Methods that produce comparable results can be used.
This document does not establish additional requirements for the following:
a) operation elsewhere than in an airport environment;
b) operation in severe conditions, e.g. ambient temperature below −20 °C or over 50 °C, tropical or
saturated salty atmospheric environment;
c) hazards caused by wind velocity in excess of the figures given in this document;
d) earthquake, flood, landslide, lightning and more generally any natural catastrophe.
This document is not applicable to GSE which are manufactured before the date of publication by CEN of
this document.

4 List of hazards
This list of risks and hazards (given in Table A.1) is based on EN ISO 12100:2010 and contains the hazards
and hazardous situations, as far as they are dealt with in this document, identified by risk assessment as
significant for this type of machinery and which require action to eliminate or reduce risks. See also the
complementary list of hazards in the other parts of EN 1915 and in the different parts of EN 12312.
5 Safety requirements and/or protective risk reduction measures
5.1 General
GSE shall comply with the safety requirements and/or protective measures of this clause, with the
requirements of EN 1915-1:2023, EN ISO 31915-3:2026 and EN 1915-4:2004+A1:2009 as relevant, as
well as with the requirements of the relevant part of EN 12312. In addition, the machine shall be designed
according to the principles of EN ISO 12100:2010 for relevant but not significant hazards, which are not
dealt with by this document.
Where a standard automotive or truck chassis is used, the manufacturer of the GSE should pay attention
to and appropriate gross mass rating for the intended use.
5.2 Requirements for the strength calculation of metal (or metallic) constructions
5.2.1 General remarks
The method of calculation shall take into account the complexity of each individual type of GSE. The
pertinence of the method of calculation shall be stated in the technical file.
Calculation models shall be performed either by
a) finite element analysis;
b) truss structure analysis;
c) hand calculations
or combinations of these.
Design verification methods shall be performed either by
d) recognized engineering design methods and engineering codes;
e) actual stress measurements
or combinations of these.
NOTE Information about load geometry is given in Annex B, Table B.1 and Figures B.1 to B.5.
The source of the design methods and engineering codes, if generally accessible, shall be stated in the
case of any unusual formulae or calculation methods. Otherwise, only formulae or calculation methods
which can be verified shall be used.
The general stress analysis shall be carried out to ensure safe levels of stress in relation to the yield stress
of the material used.
Safe levels of stress related to the loading conditions shall be demonstrated for all supporting structures.
The principal dimensions, cross sections, materials and fastening means shall be stated.
The calculation shall be performed considering second order theory or large displacements analysis. Test
results, if available, shall be used to modify calculation parameters. The analysis of the load case
combinations intended shall be carried out to ensure that the severest individual load ratings can be
identified.
The global and local stability (buckling) of the GSE shall be proven according to design verification
methods given in 5.2.1. Eigenvalue buckling analysis is permitted.
Consideration shall be given to high dynamic forces which can be caused by the operation of a safety
device for the prevention of unintentional movements if there is an escape of fluid in a piping system or
a rope, chain, nut or gear fails.
The design of mechanical restraint devices shall take into account all loads and forces occurring during
blocking.
Where a system has two or more lifting elements in parallel, design shall ensure the loads resulting from
the failure of one element shall not have effects jeopardising safety. These loads shall be considered in
structural design to ensure the safety and integrity of the structure under exceptional circumstances. The
structure shall be stable but plastic deformations and / or local instabilities are allowed. The loading
condition for this accidental case shall be the combination of all vertical loads: 1,0 × dead weight +
1,1 × (live load + snow load). Resonance effects shall be avoided for live load.
Strength calculations can be performed using recognized methods such as Eurocode 3 for steel structures
(EN 1993-1-3:2024), the FKM-Guidelines, Computational strength verification of machine components ,
EN 13001-2:2021 or other recognized calculation methods.
5.2.2 Loads and load combinations
5.2.2.1 The following loads or worse combinations thereof shall be taken into account:
a) dead weight;
b) live load;
c) local loads;
d) snow load;
e) dynamic forces;
f) resonance;
g) wind load.
NOTE Load combinations are given in 5.4.5.
5.2.2.2 Loads shall be used in the calculation of the strength of the elements concerned at the most
unfavourable positions, values and directions, e.g. Table 3.
5.2.2.3 The live load shall be stated, and shall be not less than 3200 N/m . Where the intended use
of the GSE is to carry persons, the live load shall be calculated on the basis of four persons per m , each
person at 80 kg.
5.2.2.4 Dynamic forces effective at the same time shall be measured under intended use conditions
or be calculated.
For GSE not designed to be driven during operation, vertical dynamic forces shall be considered to be at
least 10 % of the component mass and live load, subject to verification by a competent authority.
NOTE See also the EN 12312 series.

5.2.2.5 For simplification of the calculation, secondary dynamic forces are introduced into the
calculation as static forces by the formula:
F = 200 N x Σ (1/i)
s
i.e. F = 200 N (1/1+1/2+1/3+.+1/i)
s
where:
i is the number of persons on the entire GSE.
5.2.2.6 The snow load shall be specified in the manufacturer instruction manual.
NOTE The snow load is depending on the geographical area of use of the GSE and can be agreed between
manufacturer and user (see introduction – negotiation).
5.2.2.7 The wind force is generally calculated by the formula:
W = c q A
where:
c is the shape factor;
A is the surface area in square metres;
q is the dynamic wind pressure in Pascals.
The dynamic wind pressure is calculated by the formula:
ρv
q =
where:
v is the wind velocity, in metres per second;
ρ is the density of air in kilograms per cubic metre.
An air density at the lowest operating temperature shall always be used. As a reference, at an operating
temperature of +15 °C, an air density of 1,225 kg per cubic metre can be used.
The maximum wind velocity shall be specified in the manufacturer instruction manual. A minimum
constant wind velocity of 20,58 m/s (40 kn) shall be considered.
NOTE The operating conditions to resist higher wind gust velocities can be agreed between manufacturer and
user (see introduction – negotiation).
For simplification, the wind velocity shall be assumed to be constant over the height of the GSE.
The shape factor c is given in Annex C, Table C.1 and Figures C.1 to C.3.
5.2.3 Materials
Type, grade, chemical composition, weldability and mechanical characteristics (e.g. yield strength,
modulus of elasticity, shear modulus) of materials used shall be stated in the technical file.
5.2.4 Factors for stress calculations
The stress factors S as specified in Table 1 are applicable for constructional metal up to a yield of
355 N/mm .
Only for accidental load, local plastic analysis is allowed.
