DRILLING RIG JOBSITE OPERATIONS
3.1 Moving the rig in the jobsite
3.1.1
Pre-planning the route
Before moving the drilling rig in the jobsite you should survey (on
foot) the area where the rig is to be placed, and plan the path of
travel by which to get there. The ground along the route must be
firm enough to support the weight of the rig, with forward or lateral gradients
(which vary according to the rig's configuration) within the limits described
below.
The tool should be held at 20-30cm from the ground, but not so low as to risk
scraping on uneven ground. This might damage the rig structure.
When moving the drilling rig the mast must always be held vertically , with the
exception of the configuration for transportaton.
On sloping surfaces, turret rotations must be very slow to prevent as much as
possible the inertial effects of the movement, that may trigger off dangerous
unbalance.
When the crawler controls are enabled, an intermittent acoustic warning is
sounded.
