摘要： In front loaders designed for drive-in attachment to tractors, two telescopic struts are pivotable between a stowed retracted position alongside the boom assembly which carries the bucket; a first deployed extended position for supporting the rear end of the detachable main portion of the loader, aided by auxiliary struts, when it is not attached to the tractor; and a second deployed extended position, in which the struts engage with abutments on the sub-frame which carries both the boom assembly and the hydraulic cylinders for pivoting the boom assembly and are secured to said cylinders, for locking the boom assembly in its fully raised position whilst the detachable main portion is attached to the tractor.

摘要： Tractor front loaders of drive-in type have brackets fixed to a tractor and engageable with a detachable sub-frame carrying a boom assembly mounting a bucket. The sub-frame is secured to the brackets by close-fitting pins causing removal difficulties, or loose-fitting pins causing loader instability and accelerated pin wear. Easy-release pins are therefore provided, each passing with substantial radial clearance through aligned axially-spaced holes in one bracket and fitting, between the holes, in an eccentric bush which fits in a boss fixed to the subframe and is rotatable by a handle into an operative position in which the pin establishes contact with one side of the holes and the boss establishes clamping contact with a cam-plate fixed to the bracket, or into an easy-release position in which the contacts are disestablished.

摘要： Tractor front loaders have sometimes been provided with struts enabling them to be locked in raised position. These struts have had to be moved bodily between operative and inoperative positions. To avoid the need for bodily movement, the struts are made telescopic and are pivotable on loader support frames fixed to opposite sides of the tractor. Loader booms, and the rams of ram-and-cylinder assemblies for pivoting the booms, are pivotable on the support frames in known manner. The struts comprise inner and outer channel sections and are pivotable between retracted inoperative positions in which they are secured to the support frames and extended operative positions in which they are secured in contact with the adjacent ends of the cylinders of the extended assemblies.
