A crane is disclosed for use with a lifting device such as a fork lift. The crane includes a crane base which is adapted to be secured to the forks of the fork lift, and an inclined crane boom which is rigidly secured to the crane base. The upper end of the crane boom defines a guide such as a pulley, and a cable such as a chain is positioned over this guide. One end of the cable is fixedly mounted to the lower end of the mast of the fork lift, and the other end of the cable is secured to a lifting hook. This arrangement provides the important advantage that the separation between the hook and the pulley decreases as the crane is elevated by the fork lift. For this reason, the lifting height capacity of the crane is greater than the lifting height capacity of the fork lift, while the effective length of the cable remains constant. In this way, the cost and complexity of winches is avoided.
