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 has continued to improve upon its original design. Transi-Lifts® are now available in several models ranging from 350 US tons to 3000 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.
In addition to the Crawler Transporters and the Transi-Lift® Mobile Crane, Lampson International fields a fleet of 350 major pieces of equipment ranging from RT and AT hydraulic cranes, lattice boom truck cranes, conventional crawler cranes including Manitowoc 999, 2250 and 18000 models. These cranes are rented to the general construction industry both operated and maintained and under bare lease agreements.
