X = not permissible / not possible 0 = no ballast required Specified as single ballast weights of 10 kg each.
For ballasting, use Layher ballast weights, Ref. No. 1249.000, of 10 kg each. The weights are fastened quickly and securely at the right place using the hand-wheel coupler.
No liquid or granular ballast substances may be used. The ballast weights must be distributed evenly to all ballasting fixing points (see pages 22 – 23)
Example: l2, r2

2 ballast weights of 10 kg each must be fastened to the left-hand side of the ladder frame, and 2 ballast weights of 10 kg each to the right-hand side
L6, R16

6 ballast weights of 10 kg each must be fastened to the left-hand side of the mobile beam, and 16 ballast weights of 10 kg each to the right-hand side
r and R relate in the case of lateral assembly always to the side facing away from the tower; l and L relate to the side facing the tower (see also Section 9, Ballasting, on pages 22 – 23)
* The specified ballast weights are only necessary when the ladder frame is used for external access (e.g. standard is swung out).
