Hall Ski-Lift Company was an American manufacturer that built and installed rope tows, t-bar and chair lifts for the ski and resort industry.

During World War II, he supervised the design and installation of many conveyor systems for manufacturing in upstate New York.

[1] Hall was working as a project manager at a large industrial equipment company in Syracuse, New York in 1945 when a friend asked him to help construct and install a rope tow at a nearby ski resort.

This led to the establishment of a side business, Hall Engineering, which constructed and installed rope tows across the northeastern United States.

He identified a good T-bar design developed by the Swiss engineer Ernst ("Ernest") Constam, who by then had relocated to Denver, Colorado.
