ACE 25/35 cwt, power winch, Type GPGS with Lister gasoline engine, Type G2

1. The ACE Power Winch is designed for general purpose haulage and hoisting; it is a self-contained and portable unit, and is powered by a 10/12 hp Lister 2-cylinder gasoline engine which is mounted, with the winch, on a channel frame.

2. Power is transmitted to the winch through a chain-driven countershaft and cork-processed friction drive pinions; the countershaft provides two ratios through which, at the governed engine peed the load within the capacity of the winch or the speed of hauling or hoisting, can be varied, the higher ratio limiting the load but increasing the speed at which work can be done.
