5.1 Description of drilling rig controls
5.1.1
General information on drilling rig controls
The drilling rig is equipped with hydraulically servo-assisted electric controls
that require very little effort to be operated, i.e., just enough to win the
resistance of the return spring and actuate the electric contact. The red lever
on the left (
E
) enables all the controls when turned horizontally (preventing
the operator from leaving the cab) and disables the controls when turned
vertically. When the operator gets out must lift the lever to lock all the
movements and inactivate various levers.
Hereafter, the directions "left" and "right" should be understood as referring to
the point of view of the operator sitting at the controls
(fig. 5.2.1.1
).
The icons also represent the rig as seen by the operator (cab side).
