Abstract: A vehicle comprises a regulation device for ordering of movements of the vehicle (1) in a horizontal plane and a control device with a calculation unit arranged to produce signals to control the control and drive means of the vehicle's wheels (3) by information from the regulation device to achieve movement as instructed by the regulation device. The regulation device is designated with the capability to, on request of a change of the vehicle's direction in the horizontal plane, order a location for a turning point (B) for the vehicle located anywhere in the horizontal plane. The control device's calculation unit is designed to calculate the instantaneous desired value of the respective wheel's angular alignment relative to a lengthwise axis of the vehicle corresponding to the location of said turning point as ordered by the regulation device and send signals to the control means so as to achieve that alignment.

Abstract: A device is provided for attaching a first part in the form of an instrument or tool to a second part in the form of a beam or such on a working machine having, on each of the parts, one engagement member fixed thereto, which are designed to be driven into engagement with each other so that the force of gravity on the first part holds the parts attached to one another. A first (17) of the engagement members is of the male-type having external surfaces converging towards each other and a second of the engagement members is of the female-type having internal surfaces converging towards each other in a corresponding way to said surfaces of the first engagement means for receiving and holding the first engagement means in the second engagement means under the influence of the force of gravity on the first part.

Abstract: The invention relates to a device for a vehicle (1) intended for handling loads, such as an industrial truck, comprising a movable arm (4) connected to the vehicle, to which a tool (5) intended to carry a load (L) is connected, and an arrangement (7) to control movements of said tool. The arm is pivotably mounted on the vehicle about a first substantially horizontal axis (8). The device comprises a member (9) for pivoting the arm relative to a chassis (2) of the vehicle. The tool (5) is displaceably arranged relative to the chassis (2) of the vehicle in the direction of the arm's (4) main longitudinal extension. The device comprises means (17) for displacing the tool. The control arrangement (7) is designed to co-ordinate the pivoting member's (9) pivoting of the arm and the displacement means' (17) displacement of the tool so as to achieve a movement of the load carried by the tool (5) along an optionally placed curve having an optional appearance in relation to the vehicle in the vertical plane.

Abstract: A wheel assembly for moving an object, such as load carrying vehicles, and similar types of machines. The assembly enables unique motion possibilities, such as changing the direction of the object's motion perpendicularly to a preceding direction of motion. The assembly includes a wheel, which can be either driven or freely rotatable, for propelling the vehicle. The rolling point of the wheel rests upon a support surface, which is positioned at a radial distance from a drive shaft. To change the direction of motion, the wheel is rotated around the drive shaft, along a circle having the aforementioned radius.

Abstract: A device for mechanically splitting cleavable objects, especially blocks of wood, comprising two rotatable splitting wheels (2) whose rotation is effected by a motor (9). The splitting wheels (2) are provided with a number of teeth (40) and rotate in the directions A and B, respectively. Blocks of wood intended for splitting are fed in their longitudinal direction, direction C, in a guide chute (20), a centering device providing centering of the blocks relative to the splitting wheels (2). The splitting wheels (2) interact to effect cleaving of the wooden blocks and throw them divided into two parts through the outlet opening (22) of the guide chute (20).
