As the need for cranes with larger capacities, higher hook heights and increased lift radii were required, Neil F. Lampson proposed the construction of a 1000 US ton lift crane that not only had the needed capacity, but retained all the functionality of a conventional mobile crane. In 1978, Neil F. Lampson, Inc. engineered, manufactured, assembled and tested the first Lampson Transi-Lift for use at a nuclear construction site in the United States. Using the already industry tested crawler transporter as a mobile foundation and equipped with multi-drum hoists, the Transi-Lift started work on a nuclear project and exceeded all expectations.
Since the introduction of the first Transi-Lift®, Lampson International, LLC. has continued to improve upon its original design. Transi-Lifts® are now available in several models ranging from 350 US tons to 2600 US tons. Innovations in design and materials have not only accommodated higher capacities, but have had the added benefit of reducing assembly times and transportation costs.
