It composed of a series of leaders, which are consist of tabular element or hard box, placed and fixed on a crane base as it can be seen from Figure-3.Not only does the leaders support the hammer and the pile but also guide them when the pile is forced into the ground

The leader can be sloped forward and backward using screw or hydraulic adjustment and attachment at the base of the equipment as shown in Figure 4 and Figure 5. It is possible to install a series of piles, without the need to move the equipment, through turning around base machine and positioning leaders.![[Image: backward-raked-pile.jpg?resize=173%2C205&ssl=1]](https://i0.wp.com/theconstructor.org/wp-content/uploads/2017/08/backward-raked-pile.jpg?resize=173%2C205&ssl=1)

Regarding pile installation in water, pile driving rig can be used to install piles in water by placing it on pontoon or leader are fixed on braced frames that mounted on pontoon as shown in Figure-6.
Moreover, it is considerably crucial to pay adequate attention to the position and alignment of the leader since any disposition would lead to hammer eccentric blows eventually the pile will be either damages or displace from its original position. Furthermore, efforts have been made to improve the efficiency of driven pile machine and the Delmag MDT 0802, which possess broad range of adjustments with great movement capacity, is compelling example. The machine on which Delmag MDY 0801 is fixed on is a wheeled hydraulic excavator that it's rams provided sideway, forward, and backward sloping leader, in addition to arrange the location of the rig in relation to the equipment. Finally, not only does the leader operation height can be changed thought leader telescoping but also it could be folded onto the base while the machine it moved from and to the construction site.
