* The specified ballast weights are only necessary when the ladder frame is used for external access (e.g. standard is swung out).
X = not permissible / not possible 0 = no ballast required
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)
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
Example:
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)
