Introduction
This European Standard defines health and safety requirements for baggage and equipment tractors
intended for towing equipment and baggage/cargo trailers on airports.
The minimum essential criteria are considered to be of primary importance in providing safe,
serviceable, economical and practical baggage and equipment tractors. Deviations should occur only
after careful consideration, extensive testing, risk assessment and service evaluation have shown
alternative methods or conditions to be satisfactory. Such deviations are outside the scope of this
standard and a manufacturer should be able to demonstrate an equivalent level of protection.
This European Standard is a type-C standard as stated in EN ISO 12100.
This document is of relevance, in particular, for the following stakeholder groups representing the
market players with regard to machinery safety:
— machine manufacturers (small, medium and large enterprises);
— health and safety bodies (regulators, accident prevention organizations, market surveillance etc.)
Others can be affected by the level of machinery safety achieved with the means of the document by the
above-mentioned stakeholder groups:
— machine users/employers (small, medium and large enterprises);
— machine users/employees (e.g. trade unions, organizations for people with special needs);
— service providers, e.g. for maintenance (small, medium and large enterprises).
The above-mentioned stakeholder groups have been given the possibility to participate at the drafting
process of this document.
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. Deviations from requirements do not fall within the presumption of conformity given
by the standard.

5.1 General requirements
5.1.1 Baggage and equipment tractors shall conform to the requirements of this standard and the

EN 12312-15:2020+A1:2022 (E)
EN 1915-4:2004+A1:2009 unless otherwise specified in this standard. The specific requirements of this
European standard take precedence over those of the EN 1915 series.
Machinery shall comply with the safety requirements and/or measures of this clause. 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.
5.1.2 Stability and strength calculations shall be carried out in accordance with
EN 1915-2:2001+A1:2009.
5.1.3 The overall dimensions of baggage and equipment tractors shall be kept to a minimum,
consistent with their function, taking into account site operational requirements.
The following information shall be determined by the manufacturer through consultation with the user:
a) overall dimensions;
b) speeds;
c) maximum drawbar pull;
d) drawbar interface heights;
e) maximum-braked train mass.
5.1.4 Internal combustion engine powered baggage and equipment tractors using liquefied petroleum
gas (LPG) shall be in accordance with the requirements of EN ISO 3691-1:2015, 4.5.4.
5.2 Driver's accommodation
5.2.1 Baggage and equipment tractors shall be equipped with seated driver accommodation.
5.2.2 The operator's seat shall be so located that the operator has sufficient room while operating the
baggage and equipment tractor so as to remain within the plan view outline of the tractor. The
minimum dimensions given in Annex B shall be applied. The dimensions shall be of suitable and
ergonomic shape to accommodate at least a 5th percentile to a 95th percentile of the population, as
shown in EN ISO 3411:2007, Figures 1 to 3, within the plan view outline of the tractor. The seat shall
not extend beyond the plan view outline of the tractor.
5.2.3 Provision shall be made for the storage of operating instructions in the vicinity of the driver’s
accommodation. This shall not obstruct the driver’s usual field of operation and view nor constitute a
dangerous obstacle in case of a frontal impact.
5.2.4 In addition to seat belts (see 5.4.5), lateral restraint systems shall be provided on each side
exposed to a risk of tipping over. Such means shall not unduly restrict the operation of the tractor, e.g.
the driver’s access, egress, movement, and/or visibility (see Annex D for recommendations). The lateral
restraint system shall:
a) be provided to reduce the risk of entrapment of the operator's head and/or torso between the
tractor and the ground in the event of a tip-over. For this purpose it shall be designed so that the

d) not unlatch when submitted to a horizontal force of 200 daN applied at the most unfavourable
point.
5.2.5 An access gate fixed on both sides or a fully enclosed cabin with doors, both complying with the
requirements of 5.2.4 are considered as a restraint system.
5.2.6 Instructions on the use of lateral restraint systems shall be provided and visible in the tractor.
Actions to be taken to reduce the risk of a tip-over shall be described in the instruction manual, see 6.3.
5.2.7 When the lateral restraint system function is achieved with a door (closed cabin), a gate, or with
movable part(s), it shall not be possible to drive the tractor, or to drive it at a speed higher than 6 km/h,
if the restraint system is not secured. The related interlocking systems shall achieve Performance Level
“b” according to EN ISO 13849-1:2015.
5.3 Driver's cabin
5.3.1 For fully enclosed cabins, in addition to the requirements in EN 1915-1:2013, 5.3.1, the rear

A rear windscreen washing unit should be provided if agreed between manufacturer and user.
5.3.2 A fully enclosed cabin shall have at least one door conforming to the requirements of
EN ISO 2867:2011, plus an emergency exit conforming to the requirements of EN ISO 2860:2008,

away from the normal exit.
5.3.3 The air intake of a heater/de-mister for a fully enclosed cabin shall be connected to a fresh air

gas.
5.4 Seats
5.4.1 Baggage and equipment tractors shall be equipped with an adjustable seat for the driver in
order to minimize fatigue during the intended work period, see also EN 1915-1:2013, 5.2.1.
5.4.2 Seat mountings shall withstand the forces which may occur during operation, e.g. braking or
coupling forces, minor collisions with trailers/dollies.
5.4.3 It shall be possible to adjust the driver’s seat without using tools.
5.4.4 Where a weight adjustable suspension seat is fitted (see 5.9.5), the adjustment shall cater for a
weight range of at least 55 kg to 110 kg. The correct adjustment of the seat to the driver’s weight shall
be easily performed and clearly visible for the seated driver, e.g. a weight scale, an index or an
automatic means (e.g. pneumatic seat).
5.4.5 A seat belt shall be fitted to all seats and comply with ISO 24135-1:2006 when of a lap type.
5.4.6 The driver suspension seat shall be selected to achieve the requirements specified in Table 1.
