5.2 Location of the manual controls
Manual controls, in particular those for speed adjustment of conveyor device, shall be located at a minimum
distance of 850 mm from every unguarded movable element of the spreading device.
5.3 Prevention of unintentional contact with the moving spreading device
5.3.1 Self-propelled machines
For prevention of unintentional contact with the moving spreading device, self-propelled machines shall have a system that prevents engagement of the spreading device if the operator is not in The operators work station and that automatically disengages the spreading device when the operator leaves the operator’s work station.
The maximum delay time for triggering the disengagement shall be 3 s
spreading devce starling shall require Intentional reactivation by means other than the automatic spreading
device disengagement control after stopping.
5.3.2 Mounted, semi-mounted and trailed machines
Technical measures shall be taken, at least, by means of an audible signal or flashing light located near the spreading device, to warn when the spreading device is running and the machine is not travelling.
Defect of signal shall be avoided. e.g. by associating Its power to that of the spreadIng device. Delay between stop of machine travel and signal emission shall be 6 s (i 2 s).
Further investigations are to be carried Out either to apply the requirement for self-propelled machines (see
5.3.1) to mounted, semi-mounted and trailed machines or establish other equally effective safety measures
(e.g. moveable guard).
5.4 Protection against projectiles
Whatever type of rotor, manure spreaders that spread to the rear shall be fitted with a grid to protect the operator from projectiles
The width of the grid shall be equal to that of the spreading device.
The grid shall have a minimum height of 2 600 mm from the ground level.
For self-propelled machines. the grid shall extend at least 1 000 mm above the SIP (as defined in Clause 3 of EN ISO 5353:1998)01 the drivers seat, unless any other part of the machine provides equivalent protection.
The grid shall be at least 200 mm above the upper path of the spreading tools (Independent of whether they are horizontal or vertical). This requirement does not apply If the height of the load body or of the grid Is higher than 3 200 mm from the ground level.
The grid shall not allow penetration of a sphere with a diameter of 30 mm maximum and have the same level of safety to a steel grid having a wire diameter of 1,8 mm
Fixed paris of the machines. e.g. load body can be considered as equivalent protection as the grid provided they comply with the above dimensioning requirements.
The maximum gap between the grid and the load body shall be 30 mm.
5.5.1.3 Front turning points
Shearing and crushing points at a distance 01 less than 850 mm from the outer contour of the machine, which are directly accessible from the side of the machine, shall be guarded at the front turning points.
If direct access to the front turning points is possible, the horizontal distance between the foremost point of the front of the moving path of the conveyor and the fixed parts of the mactime shall be at least 100 mm (see Figure 3 a)).
If access to the front turning points is only possible indirectly (e.g. by circumventing a guard), the horizont distance between the foremost point of the moving path of the conveyor and the fixed parts of the machine may be minimized to 25 mm. In this case, the lower guard shall extend rearwards from the fixed parts at least to the vertical plane through the axle of the chain sprocket axle I deflection rots. The distance between the moving path of the conveyor and the guard shall be at least 100 mm. The distance of 100 mm from the outer moving path of the conveyor to the guard shall at least be provided over a length of 130 mm from the rearward edge of the guard (see Figure 3 b)).
When operating in the spreading direction, the areas at the turning points of the conveyor where the chains run onto a sprocket or deflection roll shaM be guarded. The guard shall prevent direct access to the crushing zones,
As far as a reverse movement ci the conveyor is possible, the upper entry point of the conveyor inside the load body shall be guarded along its width. This does not apply if the machine is equipped with a hold-to-run control for the reverse operation of the conveyor.
Shearing and crushing hazards which may occur during contact of the conveyor slats with the loading platform or the guide plates at the turning points and which could not be avoided due to functional reasons, shall be identified by safety signs on the machines where foreseeable access could be gained to these shearing and crushing points. The safety signs and their position on the machine shall be indicated In the operators manuaL See also 7.1.w).
