Some embodiments of the invention provide a lift arm including an attachment assembly and an electrical supply line having a first end and a second end. The first end is fixed in relation to the lift arm and the second end has a connector coupled to a mounting plate. The lift arm includes a first bracket affixed to the lift arm and a second bracket affixed to the attachment assembly. The mounting plate is moveable between and removably securable to the first bracket and the second bracket.

An improved arrangement for multi-position attachment points for hydraulic implement coupling. Hydraulic hoses associated with an implement attachment assembly may be removably coupled to a lift arm when in a non-operating configuration, and removably coupled to the attachment assembly when in an operating configuration.

A multipurpopse bucket comprising a front section and a rear section rotatably coupled with the front section. As such, the bucket is configured to transition from a closed position to an open position. The bucket further comprises a single actuator configured to transition the bucket between the closed position and the open position. The actuator is centrally positioned with respect to a width of the bucket.

A clamp assembly comprising a pair of clamps may couple to an assembly body. The clamps may pivot to receive material beneath the assembly body. The clamps may include opposing surfaces that define a scoop space beneath the assembly body. Each of the clamps may include a cutting plate. The cutting plate may include a perforating edge configured to extend into the scoop space relative to a corresponding one of the opposing surfaces. The clamp may further include a retention plate. The retention plate may include an inner surface that faces the cutting plate. The cutting plate and the retention plate further define the scoop space between the clamps. The clamp assembly may couple to a lift assembly. The lift assembly may include a hydraulic actuator configured to raise and lower the clamp assembly.

A scraper attachment for excavators for removing synthetic coatings on cylindrical surface object and the like. The scraper attachment has fixed and movable jaws with opposing scraper blades to grasp, hold and scrape an applied bonded coating from the object by oppositional fixed and movable action of the scraper blades in repetitive engagement.

A clam bucket assembly comprise an assembly framework which comprises an upper section and a lower section. First and second clam buckets are supported by the lower section of the assembly framework, a first bucket cylinder controls operation of the first clam bucket to engage and discharge a desired bulk material, and a second bucket cylinder controls operation of the second clam bucket to engage and discharge a desired bulk material. The clam bucket assembly supports its own independent power module for supplying hydraulic power to at least the first and the second bucket cylinders and controlling operation of the first and the second clam buckets. The power module is supported by the upper section of the assembly framework, and the clam bucket assembly is completely powered solely by the power module and controlled by radio remote control receiver and transmitter.

A debris grapple bucket attachment for securement with the loader of a compact tractor, generally used in conjunction with the front end loader of a tractor, the attachment comprising a grapple incorporating a grapple bucket for use in combination with a front rake like member, with the grapple bucket having sidewalls, a formed back wall, all structurally integrated together, with the rake like member being secured with an electrically operated industrial linear actuator, to provide for pivoting of the rake like member from an open to a closed position as when urging debris onto its grapple bucket, and to retain the same, for removal.

A material handling bucket apparatus including a material handling bucket and method of use thereof. The material handling bucket includes a bucket back half and a bucket front half. The bucket back half is configured to engage a loader. The bucket back half includes a plurality of guide slots and a dozer scraping lip configured to engage a surface. The bucket front half is pivotally coupled to the bucket back half. The bucket front half includes a plurality of slide members receivable in the plurality of guide slots. The plurality of slide members are configured to slide within the plurality of guide slots to allow the bucket front half to move linearly and pivotally relative to the bucket back half.

The invention relates to a work device having a body with an attachment arrangement to attach the work device to a set of booms of a work machine. A pair of jaws fitted to the body includes two jaws arranged to form a grab. A first jaw is fixed to the body and a second jaw is pivoted rotatably to the body to open and close the grab. The rotatable jaw is arranged to be acted on by a hydraulic actuator, to open and close the grab. Between the hydraulic actuator and the rotatable jaw is a wide-angle pivot setup. An arm mechanism, equipped with two pivots fitted to a jaw arm is arranged to belong to the wide-angle pivot setup. In addition, the wide-angle pivot setup is arranged to include a rotatable lever arm fitted between the jaw arm and the body. The rotation angle of the movement created in the rotatable jaw by the wide-angle pivot setup has a magnitude of more than 120°.

Attachments for excavators and the like for improved gripping, handling, and processing of materials and debris are provided having one or more work surfaces to provide enhanced material handling characteristics.
