A carrier comprising at least one hydraulic cylinder having a piston, a controller and a piston position sensor, wherein the carrier is arranged to carry a tool through the use of the hydraulic cylinder and wherein the controller is configured to: receive control input for moving the tool; receive piston position information for at least one piston of the at least one cylinders; determine a current angle for the tool based on the piston position information; and determine that the current angle approximates a desired angle, and in response thereto halt the tool at the desired angle. According to an aspect the controller may be configured to detect and determine the position of a subject relative the carrier based on hydraulic pressure information and tool operational information. Further, the application concerns methods applied with the embodiments of said carrier.

The invention relates to an anchoring kit for a drilling machine provided with a frame, the anchoring kit including at least a first anchoring module having: a first part including an anchoring device for immobilizing the first part in the soil; a second part including a device for fixing to the frame; and a displacement device for moving the second part relative to the first part along a first direction.

A controller for use with a working machine includes a machine body and a load handling apparatus coupled to the machine body and moveable by a lift actuator and a sway actuator. The controller receives a signal representative of the position of the load handling apparatus and a signal representative of a stability of the working machine. The controller determines a movement range of the load handling apparatus about the sway axis and issues a signal for use by an element of the working machine. The controller restricts or prevents movement of the load handling apparatus outside of the permissible movement range relative to the lateral reference orientation, the permissible range being dependent on the signal representative of the position of the load handling apparatus with respect to the machine body or longitudinal reference orientation and the signal representative of the stability of the machine.

One embodiment of an outrigger footpad retainer system is described and depicted. The system may include a spider assembly that has an upper unit and a lower unit. The upper unit may have a retainer portion and two legs extending from the portion. The lower unit may have a retainer portion and two legs extending from the portion. The upper portion may at least partially overlap the lower portion.

A stabilizer system in a work machine. The stabilizer system includes a stabilizer pad and a stabilizer arm. The stabilizer pad includes a main body having a lower surface configured for engaging a ground surface of a first type, and may include resilient inserts for resting on hard surfaces such as concrete or asphalt. Wings are rotatably connected to the main body and are rotatable between a position above the main body and a position covering the lower surface. The wings include ground engaging surfaces having ribs configured for engaging ground surfaces of a different type, such as soil or gravel. Locking pins are provided for holding the wings in selected positions.

The invention relates to a support assembly for supporting a vehicle including an articulated interconnecting assembly pivotable connectable to a lower part of the working machine; a telescopic arrangement connected to said articulated interconnecting assembly and including a guiding frame and a telescopic extension member displaceable arranged relative the guiding frame; a foot connected to said telescopic extension member; an articulated linkage arrangement having a linkage arm connectable at one end to a linear actuator for effecting a movement of said articulated interconnecting arrangement and at a second end pivotable connected to one end of a connecting rod, said connecting rod being pivotable connected to the telescopic extension member at a second end, wherein said telescopic extension member includes a channel for accommodating a portion of the connecting rod.

A carrier comprising at least one hydraulic cylinder having a piston, a controller and a piston position sensor, wherein the carrier is arranged to carry a tool through the use of the hydraulic cylinder and wherein the controller is configured to: receive control input for moving the tool; receive piston position information for at least one piston of the at least one cylinders; determine a current angle for the tool based on the piston position information; and determine that the current angle approximates a desired angle, and in response thereto halt the tool at the desired angle. According to an aspect the controller may be configured to detect and determine the position of a subject relative the carrier based on hydraulic pressure information and tool operational information. Further, the application concerns methods applied with the embodiments of said carrier.
