A genset chassis for mounting a genset including an engine and generator thereon, comprising: a pair of inner beams positioned parallel to each other and spaced apart by a distance (d), each inner beam including an outer sidewall distal from a longitudinal axis of the genset chassis ; and a plurality of outer beams , each outer beam coupled to a corresponding inner beam , wherein the inner beams are structured to mount a portion of the genset thereon such that a portion of the genset is lower than a portion of the plurality of outer beams , characterized in that : an inner sidewall of each outer beam abuts the outer sidewall of a corresponding inner beam so that an engine mounting surface of each inner beam is inset towards the longitudinal axis of the genset chassis relative to the corresponding outer beam; each of the plurality of outer beams is vertically offset from the corresponding inner beam such that each of the plurality of outer beams is higher than the corresponding inner beam, and the engine can be positioned on the pair of inner beams so that a part of the engine is lower than at least a portion of the plurality of outer beams ; and the outer beams are structured to be positioned on a plurality of mounting members positioned on a surface (G) so that a distance (H1) between a lower sidewall of the pair of inner beams and the surface (G) is less than a distance (H2) between a lower sidewall of each the plurality of outer beams and the surface (G). a pair of inner beams positioned parallel to each other and spaced apart by a distance (d), each inner beam including an outer sidewall distal from a longitudinal axis of the genset chassis ; and a plurality of outer beams , each outer beam coupled to a corresponding inner beam , wherein the inner beams are structured to mount a portion of the genset thereon such that a portion of the genset is lower than a portion of the plurality of outer beams , characterized in that : an inner sidewall of each outer beam abuts the outer sidewall of a corresponding inner beam so that an engine mounting surface of each inner beam is inset towards the longitudinal axis of the genset chassis relative to the corresponding outer beam; each of the plurality of outer beams is vertically offset from the corresponding inner beam such that each of the plurality of outer beams is higher than the corresponding inner beam, and the engine can be positioned on the pair of inner beams so that a part of the engine is lower than at least a portion of the plurality of outer beams ; and the outer beams are structured to be positioned on a plurality of mounting members positioned on a surface (G) so that a distance (H1) between a lower sidewall of the pair of inner beams and the surface (G) is less than a distance (H2) between a lower sidewall of each the plurality of outer beams and the surface (G). an inner sidewall of each outer beam abuts the outer sidewall of a corresponding inner beam so that an engine mounting surface of each inner beam is inset towards the longitudinal axis of the genset chassis relative to the corresponding outer beam; each of the plurality of outer beams is vertically offset from the corresponding inner beam such that each of the plurality of outer beams is higher than the corresponding inner beam, and the engine can be positioned on the pair of inner beams so that a part of the engine is lower than at least a portion of the plurality of outer beams ; and the outer beams are structured to be positioned on a plurality of mounting members positioned on a surface (G) so that a distance (H1) between a lower sidewall of the pair of inner beams and the surface (G) is less than a distance (H2) between a lower sidewall of each the plurality of outer beams and the surface (G). <EOS>
