BS EN 15597-1:2020 pdf free download – Winter maintenance equipment一 Spreading and spraying machines Part 1: General requirements and definitions.
For spreader with total liquid capacity till 4000 1, a 2” (inch) thread shall be available for fast coupling connection for filling liquid spreading agent tanks accessible from ground. For higher capacity, a 3” thread shall be available. 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 A.
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 mm to fill complete the tanks or, at least 500 1/mm for total liquid capacity till 4000 1, and 1 200 1/mm for total liquid capacity higher than 4 000 1. The manufacturer shall provide in the manual the information about filling pressure to reach this filling performances.
Emptying of tanks and feeding pipes shall be ensured by a valve operating from the ground.
Bursting of tanks shall be prevented by an air overflow system dimensioned to allow the right ventilation during filling, and to avoid the exit of liquid agent.
4.7.3 Stationary emptying
There shall be a suitable means provided to empty the hopper when spreader is stationary not through spreading disc. The time to empty the full hopper shall be no more than 15 mm or at least 350 kg/mm.
4.8 Operation and control system
4.8.1 Operating voltage
4.8.2 Degree of protection
All electric unit outside of driver’s cab shall be protected against dust and waterproofed according to EN 60529, degree of protection: 1P66 (excluding lights).
4.8.3 Control related spreading
i ne controi DOX snaii De ergonomicay piacea wirnin goou reacn ior ne ariver. its aernounung ana remounting shall be possible without special tools and shall not take more than 30 mm.
The control box shall have a device for switching ON/OFF the complete unit, and another for switching ON/OFF spreading operation.
All functions for spreading operation necessary to the driver (spreading dosage [g/m2], spreading width [m], spreading track position, pre-wetting [ON/OFF]) shall be directly accessible on the control box.
All spreading parameters shall be easily readable by the driver on the control box.
4.8.6 Control box alarms
A warning alarm shall be activated when the minimum brine level is reached.
If close loop system is present on the spreader, the control box shall have the following alarms:
a) in case of breakdown of conveyor, spreading disc and liquid pump (with pre-wetted option), or deviations from set values;
b) the driving speed for spreading operation is too high to obtain the requested spreading values.
4.8.7 Selection of spreading agent
Settings for at least two different solid spreading agents with bulk density from 0,8 t/m3 to 1,8 t/m3 shall be possible.
4.8.8 Data recording
For recording the necessary data, EN 15430-1 applies.
4.8.9 Emergency operation
In case of control box breakdown during winter service, it shall be possible to continue spreading operations, adjusting manually without tools:
a) ON-OFF spreading operation;
b) start-stop auxiliary engine (when present);
c) spreading dosage (solid or/and liquid when present).
