A stacker (10) for picking up objects (12) from a first location (14) and stacking the objects at a second location (16) is disclosed. The stacker (10) includes a vertically extending support column (18), a swing arm (20) pivotally mounted to the support column about a vertical axis, and a pick-up head (22) suspended from the end of the swing arm. The support column (18) includes a stationary inner boom (24) configured for attachment to a floor or support base, an outer boom (28) telescopically received over the inner boom, and a hydraulic cylinder (30) for raising and lowering the outer boom relative to the inner boom. The swing arm (20) is coupled with the outer boom (28) so that the swing arm and pick-up head (22) are raised and lowered by the hydraulic cylinder (30).
