4.4 Requirements on drives for spreading machines

4.4.1 Drive by hydraulic unit of carrier vehicle

For this mode of drive EN 15431 applies

4.4.2 Drive by hinged wheel and carrier vehicle wheel-hub drive

Stationary emptying system shall be ensured by internal or external device allowing to drive the spreader with carrier vehicle stationary All the functions shall be possible as in driving operations

4.5 Design requirements

4.5.1 Spreading device

The whole of the spreading device shall be designed to avoid congestion of agents during normal operation

In traffic areas (excluding airport runways and taxiway) the highest point of spreading agents trajectory (the visible main flow) shall be no more than 600 mm from ground (see Figure 2)

11

Figure 2 — Spreading device

Ground clearance between spreading disc and road surface, with fully loaded hopper, shall be minimum

300 mm (see Figure 2)

The spreading device shall be designed to enable

a) the connection of a trailer by the carrier vehicle, without use of the spreader;

b) stationary emptying

The spreader shall allow to collect spreading agent directly from the conveyor and not through disc for dosage tests operations (see Annex A)

4.5.2 Equipment for spreading agent pre-wetted

A 2-inch thread shall be available for fast coupling connection for filling liquid thawing media tanks accessible from ground

When the spreader is equipped with an automatic system able to shut off the external filling pump when the tanks are full, the connection shall respect the diagram shown in Annex B

There shall be a level indicator legible from the filling operations (readable scale with division of at least one tenth of the maximum tank volume) Design of tank(s) and feeding pipes shall permit a filling performance of

5 min to fill complete the tanks or at least 500 l/min

A warning alarm shall be activated on the control box when the minimum brine level is reached

Emptying of tanks and feeding pipes shall be ensured by a valve operating from the ground

Liquid overflowing shall be avoided to prevent bursting of tank and corrosion of the vehicle

4.5.3 Stationary emptying
