3.21
accessible zone
volume where a standing operator can apply a force in order to raise/lower the ROPS
3.22
pinching
dangerous point where parts move in relation to each other or to fixed parts in such a way as may cause persons or certain parts of their bodies to be pinched

5.2.3 Means to lash the tractor to the ground
5.2.3.1 Anchoring rails with the requisite track width and covering the necessaiy area for bshing the tractor shall be rigidly attached to a non-yielding base beneath the pendulum,
5.2.3.2 The tractor shall be lashed to the rails by means of steel cable of construction Class 6 x 19, Grade 1 770, with nominal diameter 13 mm according to Iso 2408. There shall be two lashings on each axle, one on each side of the median plane of the tractor. The lashings shall be anchored in the area immediately below the pivot points and extending for approximately 9 m along the pendulum block axis and approximately 1 800 mm to either side. The points of attachment of the lashings shall be sufficiently long to have an angle of 300 between the ground and lashing. Details of the lashing means are given In Figures 5.6 and Z.
The front and rear wheels are not required to be in line if this is more convenient for attaching appropriate ropes.
5.2.4 Wheel beam
A softwood beani, of cross-section 150 mm x 150 mm. to restrain the rear wheels when striking from the front or rear, and to clamp against the side olihe front and rear wheels when striking from the sIde, as shown in Figures 5.6. and 7. It may be necessary to use two beams if the outer sides of the front and rear tyres are not In the same vertical plane.
5.2.5 Wheel prop
Wooden prop to restrain the opposite rear wheel when striking from the side as shown In Figure 7. Its length shall be 20 to 25 times its thickness and its width 2 to 3 times its thickness. The prop shall then he placed against the rim of the most heavily loaded wheel opposite to the point of impact, pushed firmly against the rim and then fixed at its base.
