Abstract
A hoist cooling system in which a motor-driven pump forces oil under pressure through the hoist load brake and overload clutch. An end cover of the hoist gear case is employed as a heat exchange member, and includes fins to further enhance cooling. Oil is conducted through the load brake and overload clutch by means of interconnecting bores formed in the countershaft supporting the clutch and brake and in the brake and clutch operating disks.
