wherein a longitudinal length of the turret is less than a corresponding longitudinal length of the frame,
wherein the telescopic lifting arm ( 11 ) is pivotable between raised and lowered positions, and
wherein when the telescopic lifting arm ( 11 ) is in the lowered position, a portion of the telescopic lifting arm ( 11 ) is superimposed on the frame ( 10 ) without being superimposed on the turret ( 12 ),
wherein the telescopic lifting arm ( 11 ) is mounted on top of the base frame ( 10 ) in a configuration such that, in use when the telescopic lifting arm ( 11 ) rotates, the base frame ( 10 ), including the motor, remains stationary;
wherein the mobile lifting system ( 1 , 2 ) further comprises:
control means, arranged on board the telehandler ( 1 ), provided to manage the operation of said powertrain assembly, adapted to receive command signals and adapted to regulate the operation of the telehandler ( 1 ) according to said command signals; and
command means ( 2 ), separate from the telehandler ( 1 ), to be activated by an operator ( 3 ) and predisposed to produce command signals;
wherein the telehandler ( 1 ) is provided with first and second stabilisers ( 13 ) and activation means, adapted to manage the operation of the first and second stabilisers and subjected to the control means, wherein the command means ( 2 ) is provided to produce stabilisation signals adapted to regulate the operation of the first and second stabilisers ( 13 ),
wherein the first and second stabilisers ( 13 ) are provided adjacent the first and second ends of the base frame ( 10 ), respectively, and wherein when the second end of the telescopic lifting arm ( 11 ) extends past the first end of the base fame ( 10 ), the second end of the turret ( 12 ) laterally extends to the second end of the base frame ( 10 ).
2. The system ( 1 , 2 ) according to claim 1 , wherein the telehandler ( 1 ) is free from a cab and from manually activatable drive commands.
3. The system ( 1 , 2 ) according to claim 1 , wherein said command means ( 2 ) and the control means are adapted to communicate remotely.
4. The system ( 1 , 2 ) according to claim 3 , wherein the command means comprises a portable remote control ( 2 ).
5. The system according to claim 3 , wherein the command means ( 2 ) comprises a remote control ( 2 ) and an element for transmitting signals ( 21 ) adapted to connect the remote control ( 2 ) and the control means.
6. The system ( 1 , 2 ) according to claim 1 , wherein the telehandler ( 1 ) is provided with a means for producing the movement of said telescopic lifting arm ( 11 ) subjected to the control means, wherein the command means ( 2 ) is provided to produce movement signals adapted to regulate the movement of the telescopic lifting arm ( 11 ).
7. The system ( 1 , 2 ) according to claim 1 , wherein the equipment ( 112 ) is adapted to grip a load or is adapted to lift a person.
8. The system ( 1 , 2 ) according to claim 7 , wherein the equipment ( 112 ) is a fork, a gripper, or a basket.
9. The system ( 1 , 2 ) according to claim 1 , wherein the turret ( 12 ) has a longitudinal length that is less than a corresponding longitudinal length of the base frame ( 10 ).
10. The system ( 1 , 2 ) according to claim 9 , wherein the telescopic lifting arm ( 11 ) is telescopically extendable between extended and retracted positions, wherein a longitudinal length of the telescopic lifting arm ( 11 ) in the retracted position is greater than a corresponding longitudinal length of the turret ( 12 ).
