In addition the machinery shall be designed according to the principles of EN ISO 12100 for hazards relevant
but not significant which are not dealt with by this document (e.g. sharp edges).

5.2

Steering system

5.2.1

Steering systems shall enable the snow grooming equipment to be steered easily.

5.2.2 The system of control of the steering system shall as a minimum comply with performance level c of
EN ISO 13849-1.
5.2.3 Snow grooming equipment shall remain steerable even in the event of failure of the drive system. If
this is not possible, or in case the steering system fails due to other malfunctions, it shall be possible to
immobilise the snow grooming equipment without losing control (see also 5.3).

5.3

Brakes

5.3.1 Snow grooming equipment shall have two independent brake systems with independent actuating
systems to the extent that one of the two brake systems shall be fully effective in the event of failure of the
other. The actuating systems shall act via separate means on different braking surfaces, such as brake pads,
brake shoes or brake plates. These braking surfaces may be accommodated in or on a common brake drum
or brake disc.
5.3.2 One of the braking systems shall act as a parking brake. A mechanical linkage shall be provided as
the means of actuation for the parking brake.
5.3.3 In exception from 5.3.1, only the parking brake function is required of one of the two braking systems
referred to in 5.3.1 if the primary snow grooming equipment drive system provides a dependable braking
effect (e.g. machines having hydrostatic drive).
5.3.4 Brake systems shall act on parts permanently connected to the driven wheels. Any disengagement of

those parts from the driven wheels shall not be possible.
5.3.5

The parking brake shall be capable of keeping the machine immobilised:

1)

without propulsion under all intended conditions (terrain, slope);

2)

on a horizontal surface with a maximum propulsion torque.

5.3.6 Brake systems shall be designed such that environmental influences such as moisture, snow and ice
do not render them ineffective.
5.3.7 It shall be possible during normal maintenance to check the condition of brake pads, brake shoes and
brake plates. It shall be possible to check the brake fluid level without the use of tools.
5.3.8 Snow grooming equipment shall be fitted with a warning system that triggers an acoustic signal that is
stronger than the surrounding noise if the driver exits the driver's cab without applying the parking brake.
Alternatively, an interlock shall be provided such that the parking brake is engaged automatically at the
opening of any cabin door (e.g. electrical switches on the doors). Disengagement of the parking brake shall
only be possible by an intentional action of the driver in the driving position.

5.4

Setting in motion

5.4.1 The snow grooming equipment shall remain immobile when the engine is started. Any inadvertent
movement shall be avoided.

5.6.1.1
Snow grooming equipment shall be equipped with an enclosed driver's cab that provides
adequate protection against the effects of the weather.
5.6.1.2
The driver's cab shall be provided with means of heating and ventilation (see also

!5.6.2.1.5").
5.6.1.3
The driver's cab shall be equipped with a roll-over protective structure (ROPS). !The deflection
limiting volume (DLV) shall be in accordance to EN ISO 3164:2013." As regards lateral and vertical
directions of load application, the requirements of EN ISO 3471:2008 apply. The loads to be applied to the
ROPS during the test shall be at least those given in Table 2 as a function of the mass (M) in kg of the snow
grooming equipment.

NOTE
Requirements for the load-application forces acting in the longitudinal direction are omitted, because risk
analysis has verified the unlikelihood of a snow grooming equipment overturning in the longitudinal direction.

In addition to 8.3 of EN ISO 3471:2008, the portion of the deflection limiting volume (DLV) above the LA line
as defined in !EN ISO 3164:2013" is allowed to deviate (lean) up to 15° laterally, !deleted text"
provided the minimum energy requirement as specified in Table 2 is met. The portion of the DLV below the LA

line can be disregarded.
!deleted text"
5.6.1.4
In order to facilitate egress in the event of an emergency, driver's cabs shall have an emergency
exit facing in a direction different to that of the normal exit. Suitable exits are, for example, a second door, a

11


BS EN 15059:2009+A1:2015
