6.4.1

LIFTING OF THE LEADER

The machine is designed for lifting and lowering the standard length leader.

6.4.1.1 PREPARATION FOR LEADER LIFTING

Drive the machine to even and solid ground. Swing the machinery deck parallel to the
undercarriage. Slight ground slope forward (max 5º) is allowed. Ground inclination to
the side and backward is forbidden during erection. Do not lift the leader if a wind
exceeding 20 m/s (72 km/h, Fresh gale). When the wind velocity exceeds 20 m/s, fresh
gale, the machine has to be lowered to the transport position.
CHECK LIST PRIOR TO LEADER LIFTING
1. There is sufficient headroom for the leader to be raised safely.
2. All the ropes are in their grooves in pulleys and drums.
3. All the ropes and hoses are free to rise with the leader.
4. The winch ropes are attached to the machine or equipment.
5. The leader is locked to the basic leader.
6. The equipment (hammer, rotary head) is locked to the leader.
7. The ram block is locked to the hammer frame.
8. The horizontal slide is fully in.
9. The leader foot cylinder is fully out.
10.The lateral inclination cylinders are fully retracted.
11.The safety lever in the cab is in the forward position.
n ATTENTION
There is a proximity switch for detecting the correct position of the horizontal slide
(i.e. in) and two proximity switches for detecting the correct position of the lateral
inclination cylinders (i.e. in) during leader lifting. The leader lift device will only
move (up or down) if these three proximity switches are activated. Moving out of
lateral inclination cylinders and horizontal slide is prevented when the leader is on
the leader lift device.
n DANGER
Hammer or other winch operated equipment must be locked always to the leader or to
be removed before using the leader lift device.
