guying cables are fixed at one end to tower 12 14 head and at the other end to an anchoring point 50 away from the bank guys 48 keep tower 12 14 in the inclined position in opposition to the weight and the bearing force of cable 52 which ensures pretension and if required an electric power or safety link between the two towers 12 14 referring to fig1 it can be seen that for a given catenary trajectory of cable 16 the height h 1 of towers 12 14 inclined according to the invention is smaller than the height h 2 of the towers set vertically the gradient is chosen so that the direction of tower 12 14 is appreciably perpendicular to cable 16 at the latter 39 s support point 46 which corresponds to a minimum tower height each tower 12 14 has two inverted v shaped legs 54 56 which join at the top 38 as shown in fig3 each leg being elongated diamond shaped to ensure the best possible resistance to buckling stresses any other structure can of course be used a platform 58 is fixed to the head of tower 12 the platform 58 being sufficiently low not to hinder the passage of the cars 30 this platform 58 facilitates sheave battery 46 maintenance and constitutes a panoramic platform access to platform 58 is facilitated by an auxiliary cable car having a.
