OH-Type HYDRAULIC OVERHEAD BEAM CRANES: Nautical Structures manufactures overhead beam crane systems specific and unique to each tender-handling application. The OH-Type Overhead beam Crane is a full-beam-width crane system that utilizes the full beam-width of the vessel to stow and support the cantilevered moment-load of the cranes. The beam-sections are supported with a series of wheel-sets and are typically transported outboard with a tensioned chain-drive system, or with a specialized linear-winch drive system. A contained hydraulic linear winch is installed into each end of the crane beam, providing service to both sides of the vessel. The winches incorporate a self-stowage feature that conceals the hook and weight assembly when the crane is stowed.
