Drilling and/or lifting machine

A machine comprising:

• a movable carriage;
• a first means for lifting and carrying a tool comprising a drilling mast.
• support means mounting the first lifting and tool carrying means on the carriage to enable the first lifting and tool carrying means to be positioned in a selected one of a plurality of different positions;
• and
• a second means for lifting and carrying a tool mounted on the carriage so as to be movable either with or independently of the first lifting and tool carrying means;
• said support means comprising a bearing pipe mounted on said carriage for rotation about a vertical axis,
• a boom member pivotally mounted on said bearing pipe,
• bearing means hingedly mounted on an end of said boom member,
• guide means rotatably mounted on said bearing means for rotation about a first axis perpendicular to a hinge axis of mounting of the bearing means on the boom member, said first lifting and tool carrying means being slideably mounted on said guide means,
• an extendible member pivotally connected between said boom member and said bearing means for pivoting said bearing means about said hinge axis through an angle of 90.degree.,
• a further extendible member pivotally mounted between said bearing pipe and said end of said boom member for raising and lowering said boom member through an upward angle of 45.degree. and a downward angle of 20.degree.,
• a still further extendible member pivotally mounted between said end of said boom member and a side part of said carriage for rotating said boom member and said bearing pipe about said vertical axis through an angle of 25.degree. to either side of centerline of the carriage, and
• an extendible arm selectively connected between said bearing means and either of a pair of hinge points on either side of a longitudinal axis of said guide means at an end of said guide means remote from said bearing means for rotating said guide means about said first axis through an angle of 240.degree.;
• whereby lifting and tool working can be performed simultaneously by said first and second lifting and tool carrying means.
