ABSTRACT A loader comprises a bucket at the end of a dipper arm swinging from a cross-member on an upstanding yoke. The- dipper arm swings between the uprights to the yoke for the bucket to pick up material on one side and deposit it on the other side. A winch actuates the bucket to dig and lift on the one side and a cam causes the bucket to turn upside down on the other side to deposit its load. The yoke can lean to the one side to extend the reach of the dipper arm and can slew about a vertical axis. The yoke can centre itself when the dipper arm swings to the other side. For travelling the whole assembly can fold into a compact bundle.
