This arrangement is employed to measure the back fat thickness at three selected locations on an animal carcass conveyed on an overhead conveyor. The arrangement includes a hydraulically operated lift device to raise and lower a single operator to enable the operator to make measurements of the back fat thickness at the first rib, the last rib and the last lumbar of the carcasses. A circuit is coupled to the lift device and synchronized to the movement of the conveyor to automatically control the movement of the lift device and to provide automatically an indication of the position of the lift device at which the operator is making each of the measurements.
