Abstract
A handling machine is disclosed that includes a telescopic lifting arm and a handling device pivotable between an emptying position and a digging position; a processing unit and a control device including a control body manually operable to generate a control signal for pivoting the arm by pivoting the control body about a first axis. A control member operable using a thumb of an operator is located on one side of the control body and is mounted so as to pivot or slide about or along a second pivot or slide axis to generate a control signal for controlling the sliding of the second segment of the arm. The control member is also movably mounted so as to pivot or slide about or along a third pivot or slide axis to control the pivoting of the handling device.
Claims17
A handling machine comprising:
- a chassis;
- a telescopic lifting arm carried by the chassis, the telescopic lifting arm including first and second arm segments that can be shifted slidingly in relation to one another, the telescopic lifting arm being mounted pivotably in relation to the chassis between a low position and a high position;
- a handling device mounted at one end of the telescopic lifting arm, the handling device being pivotable in relation to the telescopic lifting arm between a discharge position and a pick-up position;
- a processing unit configured to control pivoting of the telescopic lifting arm, sliding of the second arm segment, and pivoting of the handling device;
- and
- a control device including:
- a control body that can be operated with an operator's hand to generate a control signal for pivoting the telescopic lifting arm by pivoting the control body toward a front or toward a rear of the handling machine about a first pivot axis, and
- a control member that can be operated with a thumb of the operator's hand, the control member being one of a rotary selector or a slider, the control member being carried by the control body on a lateral side of the control body corresponding to an area where the thumb of the operator's hand is positioned and being mounted one of pivotably or slidingly in relation to the control body about or along one of a second pivot axis or a first sliding axis to generate a control signal for sliding the second arm segment of the telescopic lifting arm,
- wherein the control member is also mounted one of pivotably or slidingly in relation to the control body about or along one of a third pivot axis or a second sliding axis transverse to one of the second pivot axis or the first sliding axis to control the pivoting of the handling device in relation to the telescopic lifting arm between the discharge position and the pick-up position.

A handling machine comprising:
- a chassis;
- a telescopic lifting arm pivotably mounted to the chassis, the telescopic lifting arm being pivotable between a low position and a high position and including first and second arm segments that are slidingly shiftable relative to one another;
- a handling device pivotably mounted to an end of the telescopic lifting arm, the handling device being pivotable between a discharge position and a pick-up position;
- a processing unit configured to control pivoting of the telescopic lifting arm, sliding of the second arm segment, and pivoting of the handling device;
- and
- a control device including:
- a control body operable via an operator's hand to generate a control signal for pivoting the telescopic lifting arm by pivoting the control body toward a front or toward a rear of the handling machine about a first pivot axis, and
- a control member operable via a thumb of the operator's hand, the control member being moveably mounted to a lateral side of the control body corresponding to an area where the thumb of the operator's hand is positioned via one or more of a second pivot axis and a first sliding axis, to generate a control signal for sliding the second arm segment, wherein the control member is further moveably mounted to the control body via one or more of a third pivot axis and a second sliding axis transverse to one or more of the second pivot axis and the first sliding axis, to control the pivoting of the handling device in relation to the telescopic lifting arm between the discharge position and the pick-up position.

A handling machine comprising:
- a lifting arm mounted to a chassis, the lifting arm being pivotable between a low position and a high position and including a first arm segment slidable relative to a second arm segment;
- a handling device mounted to the lifting arm, the handling device being pivotable between a discharge position and a pick-up position;
- a processing unit configured to control movement of the lifting arm, the second arm segment, and the handling device;
- and
- a control device including:
- a control body pivotable about a first pivot axis to generate a pivot control signal for the lifting arm, and
- a control member moveably mounted to the control body about one or more of a second pivot axis, a third pivot axis, a first sliding axis, and a second sliding axis to generate a sliding control signal for the second arm segment, wherein one or more of the third pivot axis and the second sliding axis are transverse to one or more of the second pivot axis and the first sliding axis, and
- wherein the control member is situated on a lateral portion of the control body corresponding to an operator's thumb.
