Abstract: Shock mounting arrangements for mounting one end of a rigid dredge ladder and for mounting the holding spud on a dredging barge or dredging platform. In the ladder mounting, pivot pins are connected to one end of the ladder for permitting pivotal movement of the ladder thereabout. The pivot pins are supported in rigid housing structures attached to the barge structure. These housing structures include a plurality of coil springs operatively engaging the pins and the rigid housing structure such that the pins are normally held in a fixed position but are permitted limited radial movement in response to dredging operation shock forces transmitted by way of the ladder to the pin means. Guide means can also be provided to limit the motion of the pin means along a single plane extending perpendicularly to the pivot axis of the ladder. Other shock absorbing means, such as hydraulic means or rubber means can be substituted for the spring means.

Abstract: Dredge ladder shock mounting arrangements for two or more part dredge ladders with a main dredge ladder part pivotally connected at a dredge platform and a secondary dredge ladder part adjustably connected to the main ladder part. The interconnecting systems for connecting the two ladder parts includes a pivot pin for accommodating changes in the angular inclination of the two ladder parts with respect to one another as well as locking members for pivotally locking the ladder parts in predetermined adjusting working positions. Shock mounting devices are interposed between the pivot pin and the two ladder parts so that relative movement of the ladder parts in a direction radially of the pivot pin axis against the shock absorbing forces is permitted.
