Abstract
A compact, self-contained device for use in safely lowering filled beer kegs from the bed of a delivery truck to the ground. The device includes a hollow drum rotatably carried within a sealed housing which can be removably interconnected to a rigid support in the load bay of the truck. A length of cable is wound about the drum and the free end thereof is connected to the keg chimes by means of a unique harness assembly. When the keg is pushed from the truck the cable is uniformly paid out from the drum against the urging of a rewind spring. The rate of descent of the keg to the ground is precisely controlled through a speed increaser housed within the drum which drives a novel centrifugal brake at high speeds producing a predetermined amount of drag on the drum. Upon disconnecting the harness assembly the cable is automatically rewound on the drum by the rewind spring.
