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, except for the mast alignment controls which remain enabled; the
mast alignment functions have their own safety control which is located on
the panel on the left (
C
). Selector D5 enables the controls that operate the
crawler and turns on an acoustic alarm that warns the persons on the ground
that the crawler may begin to move.
The external and internal emergency buttons stop the engine and
consequently all machine functions.
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).
