An loader is provided that has a body which is pivotable in a mid-section, a primary linkage pivotally mounted to the body, a secondary linkage pivotally mounted to the primary linkage, and a grapple pivotally mounted to the secondary linkage to carry a load positioned forward of the body. The improvement includes means for determining the positions of the primary and secondary linkages, and means for measuring the weight of a load being carried by the grapple. The control system has the capability of receiving from the means the positions of the primary and secondary linkages and the weight of the load and calculating whether the load is in an unstable position. If the load is unstable, the operator is prevented from moving the load to a more unstable position, but is not prevented from moving the load to a more stable position.
E02F 3/34 - DredgersSoil-shifting machines mechanically-driven with digging tools mounted on a dipper- or bucket-arm, e.g. dippers, buckets with bucket-arms directly pivoted on the frames of tractors or self-propelled machines
A system and apparatus to fasten a cab and riser to a heavy machine is described herein. A riser may include a frame that has therein a plurality of pivot pins. The pivot pins may have clamping elements coupled thereto. The respective distal ends of the clamping elements may be coupled to activation screws. When force is applied to a respective activation screw, a respective clamping element may rotate around a respective pivot pin to become clampingly engaged with a receiving structure on the heavy machine.

B62D 33/07 - Drivers' cabs movable from one position into at least one other position, e.g. tiltable, pivotable about a vertical axis, displaceable from one side of the vehicle to the other tiltable characterised by the device for locking the cab in the tilted or in the driving position
Embodiments described herein provide methods, apparatuses, and systems for moving, loading, and/or sorting logs. A log grapple may include opposing arm assemblies and independently positionable drive wheels disposed between the arms. The log grapple may be operable in a grapple mode, in which the arms are in a closed position and the drive wheels are in an open position, and a feed mode, in which the arms and the drive wheels are in closed positions. In feed mode, the first and second drive wheels may be rotated to drive the log through the arms. The log grapple may be further configured to delimb, measure, and/or cut logs in the feed mode. A log grapple may also include a measuring wheel assembly. Optionally, the measuring wheel assembly may include a hydraulic actuator configured to retract the measuring wheel and a gas spring configured to extend the measuring wheel.
B66C 1/58 - Gripping members engaging only the external or internal surface of the articles and deforming the articles, e.g. by using gripping members such as tongs or grapples
B66C 1/68 - Load-engaging elements or devices attached to lifting, lowering, or hauling gear of cranes, or adapted for connection therewith for transmitting forces to articles or groups of articles mounted on, or guided by, jibs
