Abstract: A light weight chassis or skid for a turbine or engine-generator combination has a relatively narrow central beam section with laterally extending wing portions which are provided with mounting pads for the engine and the generator. The chassis is supported on a supporting surface by three resilient motor mounts, two of which are connected to wing portions and the third is positioned under the center line of the beam portion and under the engine. The three mounts enable securing the chassis to irregular surfaces without twisting the chassis and affecting alignment problems of the engine output shaft and the generator shaft, which misalignment can cause bearing wear and other maintenance problems.
