A log hauler device is provided. In some embodiments, an example log hauler device includes a frame attachable to a small machine, and one or more log hauling components attached to the frame.

A device for securing logs from harvested timber to a transport vehicle, or logging truck, using log wrappers. The log wrapper securement device can be located in the inspection cavity of a forestry grapple. The forestry grapple is attached to a log loader. The log wrapper securement device includes a base plate sized and shaped to replace the inspection plate covering the inspection cavity. The base plate includes a slot sized and shaped to receive a portion of a chain end link or other chain links of the log wrapper, which can be inserted manually. The loader operator can remotely control the actuator to secure the chain link and release it, once the log wrapper is positioned over the other side of the logging truck. The log wrapper securement device can potentially reduce injuries and save lives.

A grapple truck with side loader having a generally J-shaped scoop in a lateral recess of the truck bed sidewall. Sometimes loader is longitudinally truncated forming an adjacent debris-bin vertical transport. The power lift system is either a direct lift-pivot with cylinder lifters or a channel-guided lifter with candy-cane shaped channels. Side loader rises from a low, manual loading position to an upper inverted dump position whereat loader displaces debris into truck bed box. Scoop's loader edge is planarly coextensive or inboard truck sidewall, and at or beneath the truck wheel axis line. A chassis mounted, articulated boom, with longitudinally extending arm segments, terminates in a grapple jaw. The articulated boom and grapple jaw has a longitudinally foreshortened stored position in and above the truck bed. In multiple operative positions, the arm extends beyond the truck bed and rear bed wall and laterally over and beyond truck sidewalls.

A grappler assembly having an assembly framework and a grappler device that is supported by the assembly framework. The grappler device has at least one pair of grappler arms that engages with a desired section of a tree to be removed. The grappler assembly incorporating its own independent power module for supplying hydraulic power to the grappler device and controlling operation of the at least one pair of grappler arms, and the power module is mounted solely to the assembly framework.

A post handling tool is adaptable for mounting on a skid steer device. It utilizes a pair of hydraulic clamps secured to a base having a vertical stabilizing pole perpendicularly secured to the base.

A work machine extending in a fore-aft direction includes a frame, a ground-engaging mechanism, a boom assembly to the frame, and a traction assist apparatus. The ground-engaging mechanism is configured to support the frame on a surface. The traction assist apparatus is coupled to the boom assembly. The traction assist apparatus has an attachment point for securing a tether.

A lever device for lifting an object off the ground includes a lever member having a distal end that is positionable immediately adjacent a bottom end of the object. The lever device also includes a grip member that is operable with the lever member to lift the object off the ground. The grip member is adjustable relative to the lever member to accommodate a size of the object being lifted off the ground. The grip member includes a toothed or hooked end that grips an upper surface of the object to be lifted off the ground. The lever device further includes a handle that is graspable by a user to impart a lever force to the grip member and the lever member and thereby lift the object off the ground.

The invention relates to a method in a weighing system, in which method the mass of the bundle is weighed and recorded during both loading % and unloading m.sub.i_p of the bundle, during loading, the total loading mass m.sub.K_kok_j is calculated from the mass m.sub.i_c of one or more bundles weighed during loading and corrected using a correction factor C.sub.j, the total unloading mass m.sub.p_kok_j is calculated from the mass m.sub.i_p of one or more bundles weighed during unloading, with the aid of the said total loading mass m.sub.K_COk_j and total unloading mass m.sub.p_kok_j, a new corrected value Cj+1 is calculated for the correction factor C.sub.j in order to adjust the weighing for the loading of the next load K.sub.j+1. The invention also relates to a corresponding software product, an arrangement, and a material-handling machine.

A grabbing device having a plurality of jaws which can be moved between an open position and a closed position to enable the device to grasp an object(s). The technology finds particular application in the forestry industry and moving logs.

A grapple for mounting to a boom of a boom crane includes a body member for mounting to the end of a boom of a boom crane including a first wing member and a second wing member and opposing first and second jaw members. Each jaw is hingably coupled to the body member, and hinges with respect to the body member by the action of a hydraulic cylinder. A first end of the hydraulic cylinder is coupled to the jaw member and a second end of the hydraulic cylinder is coupled to a portion of one of the wing members. The first and second wing members extend to position the second end of each hydraulic cylinder rearward of an end of the boom of the boom crane or a coupling between the body member and the boom of the boom crane.
