Abstract

A manual hoist and traction machine wherein an outer diameter of a first lining plate constituting a mechanical brake is made smaller than an inner diameter of a driven disc of a handwheel. The outer diameter of a second lining plate and of a driven disc are made smaller than an inner diameter of a cylindrical portion of a braking ratchet wheel, and the first and second lining plates are formed of a lining raw material having improved performance with a compressive strength of 15(Kgf/mm2) or more and a maximum strain of 12(10-3 mm/mm) or more.
