1.1 General references to the avoidance of accidents, damages
and excessive wear
1 Drill rig
The drill rig has multiplicity kinematic degrees of freedom for positioning of the basic
rig and particularly the drill mast.
But not each kinematically possible configuration is meaningful or permissible. This
particularly depends on the mounted drill mast, the drilling unit and drilling equip-
ment.
Therefore among other things the permitted drilling positions given in the stability
calculations, the setting- up sequences and the specific ground pressure as well as
all other references in the manual must be observed.
KLEMM Bohrtechnik refers to the fact, that not each theoretically possible drilling
position can be described.
If other drilling positions are to be aligned, then this lies in the technical discretion
of the operator. Otherwise consultation with KLEMM Bohrtechnik must be taken.
The following points must be particularly considered:
1.1 Extreme displacement of the center of gravity
Special attention must be paid when setting-up the drill mast with far out overhan-
ging center of gravity. The center of gravity of the drill mast with its attachments e.g.
drill heads and hydr. drifters, drilling equipment and if necessary rod magazines
must be placed as near as possible to the ground contact area of the drill rig. The
ground contact area of the drill rig is defined by the tipping edges of the crawler
tracks.
1.2 Collision
Causes of the multiplicity of kinematic possibilities, the setting- up of the drill rig has
to be done with maximum attention, appropriate speed and if necessary with a se-
cond instructing person.
With inattentive setting-up operations, collisions e.g. between the drill mast and
parts of the boom or the basic rig are possible.
1.3 Overlay of the degrees of freedom
The kinematic degrees of freedom are for example realized by hydraulic cylinders
or slewing drive units. The degrees of freedom can be redundant in certain positions,
that means for example, that a tilting motion around a certain spatial axle can be
achieved by two or more methods. Within the methods, the most favorable method
regarding endangerment and damage must always be selected.
