Division 8.1.2

United Kingdom

Drawing details are to be provided to demonstrate that the compensator articulation is sufficient to ensure equal cable tension is applied to each of the rear cables. The compensator needs to have sufficient distance across the width to facilitate the differential travels left to right. The jaws of the yokes also need to be deep enough relative to their width to make sure that they do not prevent articulation when the compensator is at an angle.

Differential travel at compensator (s_cd) shall be derived from:

s_{cd} \geq 1,2 \times (S_{cr} - S_{c}')

Where:

S_c′ = S′/i_H	(travel at compensator — forward operation) and S_c′ = 2 · S_B/i_g
S_cr = S_r/i_H	(travel at compensator — rearward operation)
