摘要： A cross support assembly is provided which is useful, for example, in earthworking equipment. Such an assembly can be mounted to extend between two lateral supports. A bracket extends laterally from the assembly and can serve as a supportive pivot for a bucket or the like. The assembly is generally hollow and acts as a torsion member. A bulkhead is welded in the cross support assembly and is positioned to directly receive forces exerted on the bracket. Usually the bracket and bulkhead are of unitary construction. The bulkhead extends within a generally tubular cross-member which also forms a part of the assembly and is attached between the lateral supports and into contact with the interior of the tubular member. Forces exerted on the assembly are thus generally compressively applied to the bulkhead welds adding to the overall strength of the assembly.

摘要： A bucket for use with a loader vehicle includes a pair of spaced reinforcement means fixed to the bottom wall portion of the bucket. Each reinforcement means defines a box section which runs transversely of the cutting edge of the bucket, including a pair of ribs which run continuously rearward from the cutting edge along the bottom wall portion and up the rear wall portion of the bucket. The ribs define first and second pairs of apertures for attaching the bucket to a loader linkage.

摘要： The bucket contains an ejector plate movable from side to side to discharge a load from either side of the bucket. Both sides of the bucket are equipped with doors which are opened and closed by double acting hydraulic cylinders and the doors are held closed and released by latch devices actuated by double acting hydraulic cylinders. The ejector plate is actuated by a pair of hydraulic cylinders arranged to move the ejector plate the entire width of the bucket. When a load is to be dumped from the right side of the bucket, the ejector plate is shifted to the left side before the bucket is loaded and when a load is to be dumped from the left side of the bucket, the ejector plate is shifted to the right side before the bucket is loaded. This arrangement allows the bucket to discharge from either side without tilting the bucket laterally.

摘要： A loader has a pair of forwardly extending lift arms with a pair of forwardly extending tilt control links above the lift arms. A loader bucket is mounted for quick attachment to or detachment from the forward end of the lift arms and control links by means of a mechanism controlled from the operator''s seat. The attachment mechanism includes a pair of transversely extending, vertically spaced hydraulic cylinders with piston rods extending from both ends of the cylinders. The upper cylinder is attached to the forward end of the tilt control links and the lower cylinder is attached to and extends between the forward end of the lift arm. The outer ends of the piston rods are extendable into and retractable from corresponding sockets on the rear side of the bucket in response to alternate pressurization of the center of the cylinders or the opposite ends of the cylinders, which is controlled by valve means at the operator''s station.
