As a result, each module is compatible with another module to provide great versatility in configuring the machine. Additionally, the system includes a variety of different modules.

LOAD SKIDDING VEHICLE

Load skidding vehicles commonly include a grapple assembly (42) which under load conditions can pivot rearwardly about its support point (52) resulting in disproportionate loading of the rear wheels and consequently instability of the vehicle. A connecting member (62) is pivotally attached between the grapple (42) and a hydraulic cylinder (74) which is attached to the skidder (2). Operation of the hydraulic cylinder (74) causes the grapple (42) to rotate about its support pivot (52). The hydraulic cylinder (74) may be locked causing the grapple (42) to be locked in relation to the boom assembly (26). During load hauling operations this mechanism is used to lock the load in a position near the vehicle resulting in increased stability. The mechanism is also of use in positioning the grapple assembly (42) with respect to the load prior to grasping it.

Clamshell bucket for earth excavator - has two segmental shells pivoting about parallel axes and flanking ripper tooth which pivots normally

The bucket has two pivoting segmental shells (16) and may be used on earth-moving machines. It includes a pivotable ripping tooth (18) which enters the ground prior to the closure of the shells (16), to reduce operational stresses on the jib (8) supporting the bucket. The shells (16) may be of identical uniform 'U' sections and pivot about individual parallel axes (17) through adjacent leg ends. The free leg ends incorporate cutting teeth (21) and meet when the shells pivot towards one another, thus, closing the bucket to load with spoil. To effect discharge of spoil the shells pivot away from one another to adopt an inverted 'W' formation. The ripper and the shells may be operated by individual rams (15, 23).

Grapple rake for backhoe

ABSTRACT A grapple rake for attachment onto the end of the dipper stick of a backhoe comprises a generally upright back jaw having upper and lower ends and front and back sides, the front side being concavely curved, and a swingable front jaw having inner and outer ends and front and back sides, the front side being concavely curved to cooperate with the back jaw. Attach-ment means are provided on the upper end of the back jaw and on the inner end of the front jaw and include a swing shaft for swingably interconnecting the jaws together and positioning means are provided for orienting the jaws relative to the dipper stick. A pair of parallel mounting ears with apertured portions protrude rearwardly of the back side of the back jaw in a spaced relation to each other to receive the end of the dipper stick therebetween, and the apertured portions have a pivot pin in the apertures thereof and extending through the dipper stick to pivotally carry the back jaw and permit the hack jaw to lie against the dipper stick while the front jaw is used for raking. The novel construction of this invention provides for more efficient raking than has been possible with previously known grapple rakes.
