1950's



1953
Marshall Elevator began manufacturing elevators for tall transmission towers. Sold around the world, Marshall Tower Elevator systems were designed to travel as high as 2100 feet with loading capacities of 950lbs.  
 


1955
Rotary Lift merges with four companies to form Dover Elevator.  Marshall becomes the exclusive distributor of Dover Elevator products in Western Pennsylvania and Northern West Virginia.


1958 - 1961
Marshall Elevator and Rotary Lift Engineers designed a 2100 seat 118 foot x 64 foot 445,000 lbs. capacity seat lift for the Pittsburgh Civic Arena, better known today as the Mellon Arena. The mechanics of this massive seat lift included a 35 foot pit with 4 hydraulic plungers that were 42 feet long and 12 5/8" in diameter. There were a total of six cylinders, three on each side, with the two in the middle serving as locking posts when raised in it's full upright position.


1963 - 1965
Marshall Elevator engineered and manufactured a temporary elevator system designed to transport workmen up and down during the construction of the St. Louis Arch. This man-lift system, designed to ascend the periphery of the Arch, could be extended as construction of the Arch progressed. An interface-free radio control inside the car eliminated the need for collector rails or hanging cables. A specially designed tilt-sensing mechanism and a motor-operated leveling device kept the cab level at all times.
