摘要： A quick-release coupling is provided between a vehicle and a material handling unit. The frame of the vehicle has a pair of opposed recesses. A linkage which is connected to the material handling unit includes first and second links which are pivotally interconnected at one end. Elements such as pins are associated with the opposite ends of the links and are each receivable in one of the recesses. A third link has one end secured to the material handling unit and an opposite end which is pivotally interconnected with the first and second links. The third link moves the first and second links between a first position in which the distance between the axes of the pins is less than the distance of the opposed recesses, and a second position in which the distance between the axes of the pins is greater than the distance between the opposed recesses and the pins are received in the repective recesses to releasably secure the material handling unit to the vehicle.

摘要： An ejector bucket for mounting on a front end or backhoe loader vehicle, provided with an ejector actuated by a mechanism that does not protrude from the bucket walls. The actuating mechanism is contained within a small area behind the ejector and is attached to the rear of the ejector and the top wall of the bucket. The absence of protruding cylinders or the like makes the bucket mountable on loaders of all designs. Flexible means connect the actuating mechanism to the engine of the loader vehicle or other power source.

摘要： Public works machine comprising a bucket mounted to pivot on the end of a boom, a device for adjusting the relative position of said bucket with respect to said boom, a ripper tooth, which is mounted to pivot on the end of the boom, while said position-adjusting device is coupled between the boom and the tooth, two selective immobilization devices, one for immobilizing the bucket with respect to the boom in a configuration where said bucket is not in operation, in which the penetrating element of this bucket is orientated towards the boom and disposed near said latter, the other for immobilizing the bucket with respect to the tooth in a configuration where said tooth is not in operation, in which said tooth is joined to the outer face of the bottom of the bucket, the distance separating the end of the tooth from the pivot axis being at the most equal to that separating the penetrating element of the bucket from said pivot axis. One application of the present invention is the production of a public works machine which is satisfactorily efficient for digging and breaking up works.
