Definitions
- the present invention relates generally to heavy equipment. More specifically, the present invention relates to a skid loader attachment including a rotatable and extendable claw.
- Skid loaders are typically four-wheel vehicles with the wheels mechanically locked in synchronization on each side, and the left-side drive wheels can be driven independently of the right-side drive wheels.
- the wheels typically have no separate steering mechanism and hold a fixed straight alignment on the body of the machine. By turning the left and right wheel pairs at different speeds, the machine turns by skidding, or dragging its fixed-orientation wheels across the ground. The extremely rigid frame and strong wheel bearings prevent the torsional forces caused by this dragging motion from damaging the machine.
- the skid-steering vehicle is turned by generating differential velocity at the opposite sides of the vehicle.
- the conventional bucket of some skid loaders can be replaced with a variety of specialized buckets or attachments that can be powered or controlled at least in part by the loader's hydraulic system.
- the present disclosure relates to an attachment for a skid loader.
- the attachment includes a base attachable to a loader arm of the skid loader, a rotatable coupling attached to the base on a side opposite the loader arm, and a claw portion attached to the rotatable coupling.
- the claw portion includes a stationary jaw and a pivoting jaw.
- the pivoting jaw pivotable with respect to the stationary jaw about a pivot rod.
- the pivoting jaw is coupled to the rotatable coupling via a hydraulic cylinder such that movement of the pivoting jaw about the pivoting rod is effected by actuation of the hydraulic cylinder.
- the rotatable coupling is configured to rotate at least 180 degrees with respect to the base.
- the claw portion is extendable from the rotatable coupling in a direction perpendicular to the base.
- the attachment further includes a spade extendable from the claw portion. The spade can be extendable from the stationary jaw of the claw portion.
- the attachment further includes a jackhammer coupled to the claw portion. The jackhammer can be coupled to the pivoting jaw of the claw portion.
- the attachment further includes a boom extending from the claw portion. The boom can be comprised of metal or wood, and can include a crane hook extendable from an end of the boom distal from the claw portion.

- The present invention relates generally to heavy equipment. More specifically, the present invention relates to a skid loader attachment including a rotatable and extendable claw.
- Skid loaders are typically four-wheel vehicles with the wheels mechanically locked in synchronization on each side, and the left-side drive wheels can be driven independently of the right-side drive wheels. The wheels typically have no separate steering mechanism and hold a fixed straight alignment on the body of the machine. By turning the left and right wheel pairs at different speeds, the machine turns by skidding, or dragging its fixed-orientation wheels across the ground. The extremely rigid frame and strong wheel bearings prevent the torsional forces caused by this dragging motion from damaging the machine. The skid-steering vehicle is turned by generating differential velocity at the opposite sides of the vehicle.
- The conventional bucket of some skid loaders can be replaced with a variety of specialized buckets or attachments that can be powered or controlled at least in part by the loader's hydraulic system.
- The present disclosure relates to an attachment for a skid loader. The attachment includes a base attachable to a loader arm of the skid loader, a rotatable coupling attached to the base on a side opposite the loader arm, and a claw portion attached to the rotatable coupling. The claw portion includes a stationary jaw and a pivoting jaw. The pivoting jaw pivotable with respect to the stationary jaw about a pivot rod. The pivoting jaw is coupled to the rotatable coupling via a hydraulic cylinder such that movement of the pivoting jaw about the pivoting rod is effected by actuation of the hydraulic cylinder. In some embodiments, the rotatable coupling is configured to rotate at least 180 degrees with respect to the base. In some embodiments, the claw portion is extendable from the rotatable coupling in a direction perpendicular to the base. In some embodiments, the attachment further includes a spade extendable from the claw portion. The spade can be extendable from the stationary jaw of the claw portion. In some embodiments, the attachment further includes a jackhammer coupled to the claw portion. The jackhammer can be coupled to the pivoting jaw of the claw portion. In some embodiments, the attachment further includes a boom extending from the claw portion. The boom can be comprised of metal or wood, and can include a crane hook extendable from an end of the boom distal from the claw portion.
