four-wheel antilock brake system [ four-wheel antilock braking system | four-wheel ABS ]

means a towed vehicle having at least two axles, and equipped with a towing device which can move vertically (in relation to the trailer) and controls the direction of the front axle(s), but which transmits no significant static load to the towing vehicle.

Annex II A.With the wire ropes tensioned, the wedging beam shall be placed firmly behind the rear wheels and then fixed to the ground.1.2.3.If the tractor is of the articulated type, the point of articulation shall in addition be supported by a wooden block at least 100 mm square and firmly lashed to the ground.1.2.4.The pendulum block shall be pulled back so that the height of its centre of gravity above that at the point of impact is given by one of the following two formulae, to be chosen according to the reference mass of the tractors subjected to the tests:H = 25 + 0,07 mt for tractors with a reference mass of less than 2 000 kilogr ...[+++]ams,H = 125 + 0,02 mt for tractors with a reference mass of more than 2 000 kilograms.The pendulum block must then be released so as to strike the protection structure.1.3.Impact from the side1.3.1.The tractor shall be so placed in relation to the pendulum block that the block will strike the protection structure when the impact face of the weight and the supporting chains or wire ropes are vertical unless, during deflection, the protection structure at the point of contact forms an angle to the vertical.

The position of the centre of gravity of the block shall be one-sixth of the width of the top of the protection structure inwards from a vertical plane parallel to the median plane of the tractor touching the outside extremity of the top of the protection structure.If the structure is curved or protruding at this point, wedges enabling the impact to be applied thereon will have to be added, without thereby reinforcing the structure.1.1.2.The tractor shall be lashed to the ground by means of four wire ropes, one at each end of both axles, arranged as indic ...[+++]ated in Figure 5 of Annex IV. The front and rear lashing points shall be located at a distance such that the wire ropes make an angle of less than 30g with the ground.

1.16.2.Full trailer Full trailer means a towed vehicle having at least two axles, and equipped with a towing device which can move vertically (in relation to the trailer) and controls the direction of the front axle(s), but which transmits no significant static load to the drawing vehicle.
