Replacement of the main winch rope
3.2.3
The main winch rope must be replaced as follows:
• configure the drilling machine in the transport configuration, placing the
Kelly stub on a support such as to have the swivel as close as possible
to the pulley;
• disengage the descent limit switch of the main winch;
• loosen the rope by a few centimetres;
• wear protective gloves;
• disconnect the rope from the rotating joint by removing the pin;
• control winch rotation to unwind the rope and simultaneously stretch it
to prevent it from getting twisted on the winch drum; do not put your
hands near the winch drum while it is unwinding;
• • release the insert "A"
, beating the block by means of a wedge "B" as shown;
