4.2.3 Spreading or injecting boom

Booms that can be manually folded/unfolded shall be fitted with two handles located at a distance of at least

300 mm from the nearest articulation These handles may be integral parts of the boom, provided they are suitably designed and clearly identified

In the case of powered operation, the control for the swivelling shall be of the hold-to-run type and the manual control shall be located outside the swivelling zone

The folding/unfolding speed shall not exceed 0,5 m/s when measured at the end of the boom

A device shall be provided to prevent the boom from moving when it is folded in the transport position If the locking device is a hydraulic valve not directly fitted to the cylinder, the bursting pressure of the circuit’s components from the valve to the cylinder shall be at least four times its allowable pressure

The locking device and the boom folding/unfolding actions shall be controlled by separate systems

The manual force necessary to adjust the height of the boom shall not exceed 250 N

Where height adjustment is by a winch, this winch shall be self-arresting and capable of withstanding at least

a load equal to 2 times the weight of the boom

The winch shall be operable from the ground

In the case of powered height adjustment, it shall be possible to actuate the manual control from the driving position and the control shall be of the hold-to-run type To ensure the protection of the operator against crushing and shearing hazards related to a failure of the control circuit, the machine shall be fitted with a device which limits the maximum downward speed of the boom to 10 mm/s

The boom shall be lockable in position for servicing and maintenance purposes

The injecting devices shall be in contact with the ground before it is possible to operate the control for putting the injecting boom in floating position or in position with weight transfer

4.2.3.3 Emptying of the boom

It shall be possible to isolate the contents of the tank from the boom in order that the boom can be emptied in the low position for transport, maintenance or removal and storage

4.2.3.4 Stability of the boom when parked and for manual handling

The boom shall be designed to be stable when parked according to the information in the instruction handbook on firm ground with an inclination of at least 8,5° in all directions

Where transport rollers are fitted to the boom for ease of manual handling when detached from the tanker, the boom and the location of these rollers shall be designed so that the boom is stable and will not overturn during such handling

This requirement shall be checked as follows: Place the boom, which has been parked in accordance with the information in the instruction handbook, on a horizontal and even plane Then push it at a speed of 1 m/s against a fixed rectangular obstacle 50 mm high with a length at least equal to the distance between the external transport rollers and located on the ground at a right angle to the direction of movement of the boom The boom shall remain upright

4.2.4 Means of access

When an opening or openings are provided on the upper part of the tank, or if for any reason access is required by the operator to the upper part of the tank, suitable means of access shall be provided

Parts of the spreading or injecting boom shall not be used as handholds related to the means of access

4.4 Requirements for pneumatically powered slurry tankers

4.4.1 Covers for openings

For pneumatically powered slurry tankers, the unrestricted opening of the covers shall be prevented by a device that allows any pressure to be vented before the retaining mechanism is fully released

4.4.2 Pressure gauge

Pneumatically powered slurry tankers shall be provided with a pressure gauge allowing the working pressure

to be read from the driving position of the tractor or self-propelled machine This pressure gauge shall be designed or located so that it can neither be rendered ineffective by the contents of the tank nor shut off by a stop valve between the pressure gauge and the tank

The allowable pressure as defined by EN 764 shall be indicated on the pressure gauge, e.g with a red line The pressure gauge shall be located or protected so that accidental damage is minimised

4.4.3 Safety valve

Pneumatically powered slurry tankers shall be equipped with a safety valve which shall be:

 designed and adjusted to prevent the allowable pressure as defined by EN 764 being exceeded by more than 10 %;

 protected against any unauthorised modification of its adjustment and be such that it cannot be put out of action by the contents of the tank;

 designed so that, if the slurry can come into contact with the valve, the minimum diameter of the passage section shall be 150 mm;

 located or arranged in such a way that liquids and gases shall not be ejected in the direction of the operator's working position;

 protected or located so that accidental damage is minimised

5 Verification of the safety requirements and/or measures

Dimensions, where given, shall be verified by measurements Controls shall be verified by a functional test and positional measurements
