Hall Ski lifts was founded by ski lift pioneer Victor Hall in Watertown NY.
In 1966 Hall entered into a marketing agreement with Pohlig-Heckel-Bleichert of 
Koln, Germany was a leader in European lift design. In the late 80's Hall was
purchased by Von Roll who continued to use many Hall designs in the US. Von Roll
was eventually purchased by Doppelmayr who merged with CTEC/Garaventa to form 
Doppelmayr/CTEC.  Halls are still considered very strong lifts and can be seen 
running throughout the country today.  They are one of the most desireable used
lifts.  Below is a 1966 PHB/Hall skycrusier gondola brochure.

The following is from a former Hall Employee:

There was never a merger of the two companies. However there was a marketing agreement, 
wherein Hall agreed to market PHB detachable and reveersible systems in North America and PHB 
agreed to attempt to market T-bars and chairlifts in Europe. I believe a few 'Hall' T-bars 
might have been built using the tubular sticks in Germany, butÊnot very many, if any. However 
Hall did sell several detachable systems in the U.S., starting with Loon Mountain's system in 1966 
(now at Lutsen, MN). Each successive system built in the U.S, used more and more U.S. components 
over time, with the last one jointly made (High Wallowas, Oregon) used only Grips and sheaves 
from PHB.

The last Gondola made by Hall was Sterling Vineyards in California, and used zero parts or 
engineeringÊfrom PHB, as the grips came from another manufacturer. They were the same principle 
and looked identical, but were not the same. 
Hall's arrangement with PHB came after PHB's arrangement with Constam endedÊupon Ernest Constam's 
death. PHB and Constam sold several systems in the U.S., including Squaw Valley and Sierra BlancaÊ
(now Ski Apache), Park City 1 and 2; and Sugarloaf 1 and 2 in Maine.
