  • Patent number: 11981543
    Abstract: A spreader for lifting an intermodal transport container includes a main beam extending in a longitudinal direction, the main beam formed of a first, upper C-beam of a relatively thicker material thickness and a second, lower C-beam of a relatively thinner material thickness; and an indicator configured to provide an indication if a distance in a transversal direction between a pair of twist-locks is set in a wide-body position when lowered onto respective lifting castings provided with top openings separated by a transversal distance corresponding to a standard position.

  • Publication number: 20230373758
    Abstract: A spreader for lifting a transport container comprises a main frame (26) suspended in a main frame suspension arrangement (36) to enable translation along a longitudinal axis (L). The main frame (26) is vertically supported by the main frame suspension arrangement (36) along a support line extending between a first support end (68a) and a second support end (68b), and the main frame suspension arrangement (36) carries the weight of a suspension arrangement load comprising the main frame (26), container connector arrangements (28a, 28b), and any container(s) attached to the container connector arrangements (28a, 28b). A detector arrangement is configured to detect if a centre of mass of the suspension arrangement load is positioned at a longitudinal position along the support line which is beyond a limit position.

  • Patent number: 11208298
    Abstract: A side lift spreader main beam (22) comprises a vertical carrier plate (58) having a first vertical height (H1) and being made of steel plate having a first thickness (T1); a C-beam (60) comprising a first horizontal flange (64) and a second horizontal flange (66) interconnected by a vertical web portion (68), the C-beam (60) having a second vertical height (H2) lower than the first vertical height (H1) and being made of steel plate having a second thickness (T2) thinner than the first thickness (T1), wherein the C-beam (60) defines, together with the carrier plate (58), a closed channel beam with a first flange (74) of the carrier plate (58) extending vertically from the closed channel beam; and an inclined support plate (62) welded to the carrier plate, and to an outer face of the first flange (64) of the C-beam (60) at a distance from the carrier plate (58).
