Ratchet-tooth rack 3 is suspended from flexible link 5 which runs over pulley 6. When lever 1 is oscillated about axis A, pawl 2, pivoted at the end of lever 1, engages ratchet-tooth rack 3, raising it with load 4. The load does not descend when lever 1 is raised because it is held by a locking pawl or brake (not shown).
