ABSTRACT OF THE DISCLOSURE A loader for use in locations with limited space. The loader has a bucket mounted on a cantilevered shaft which extends to one side of a single dipper arm. The side of the bucket remote from the dipper arm is freely exposed enabling the loading of material which is larger then the bucket. The dipper arm is pivotally mounted on an upright arm which is supported by a ram. The dipper arm is movable to discharge the bucket by means of a ram which acts on a toggle linkage. Orientation of the bucket is maintained by means of a ram which via a chain acts on two drums which are connected by means of a second chain to a third eccentrically mounted drum.
