For attachment to mechanical and hydrostatic rope excavators with special lattice boom , leader suspended on gimbals, support on superstructure hydraulically adjustable, hydraulically driven by rope excavator or by separate unit, with control and inclination measuring device for leader with 45° to 60°. Slewable to both sides and lowerable to beneath the subgrade. Inclination of leader: 3:1 forwards and backwards, 20:1 sideways. With inclinations during use of 1:1 or less, the payload consisting of ram + pile cap + pile is reduced by approx. 50% (leader including suspension gear, bracing and rope deflection). Without ram, pile cap.
Certain leader designs alternatively also suitable for pendulum leader applications.
Rope excavators see D.0.00 resp. D.0.01.
