A prefabricated, modular bridge is provided that can be assembled to construct bridges of various lengths, widths and skew angles relative to the orientation of foundation elements. The modular bridge includes longitudinal frame members, and a roadway surface made of roadway deck panels and transverse hubs. The transverse hubs define transverse ledges to support ends of the roadway deck panels. The transverse hubs have attached hub attachment clamps that move transversely relative to the transverse hubs to selectively disengage or engage the top flanges of the longitudinal frame members. An assembly for splicing the longitudinal frame members is provided, including an anchor bolt extending between bearing support members attached to the longitudinal frame members. An external reinforcing assembly for the modular bridge is also provided. The external reinforcing assembly includes longitudinal tendons, anchor blocks, and spacers and hangers for deviating the tendons from the bottom flange of the frame members.

According to one aspect, a vessel ramp assembly system includes a ramp assembly configured to assist with ingress and egress of an individual with respect to the vessel, a deployment system configured to move the ramp assembly between a stowed position with respect to the vessel and a deployed position with respect to the vessel, and a positioning system configured to move the ramp assembly to move a first end of the ramp assembly with respect to a deck of the vessel and provide a second end of the ramp assembly at an appropriate position where the individual may use the ramp assembly for the ingress and egress with respect to the vessel.

A hybrid truss assembly with a truss bay centrally deployed, and with half-bays deployed on either side. The configuration provides four panels (such as solar panels), with two chords connected by four transverse members. The half-bays are locked in a rigid position using a barrel lock hinge assembly. The half-bays fold compactly beside the folded center bay assembly when retracted. The truss assembly may be pivotally mounted on a mobile cart, and may then be manually or automatically tilted or rotated to a desired angle.

A mount for receiving and retaining at least one ramp. The mount includes a first side and a second side. The first side includes a body portion, at least one engagement finger extending in a first direction and at least one engagement finger extending in a second direction. The second side includes a body portion, at least one engagement finger extending in the first direction and at least one engagement finger extending in a second direction. In example embodiments, at least one spacer member is coupled to the body portion of the first and second sides so as to provide at least some spacing between the first side and the second side. In example embodiments, the mount can be attached to a wheeled vehicle for removable attachment of one or more ramps thereto. In some example embodiments, the wheeled vehicle is a lawn mower.

A bridge span assembly can include multiple bridge spans, each of which can include a frame, a stabilizing member for engaging with construction equipment, and a coupling joint for attaching the frame to construction equipment with an elongate member. By attaching the bridge span assembly to construction equipment with the stabilizing member and coupling joint, an operator can place the bridge span assembly over an obstacle using only the construction equipment. The construction equipment or other equipment can then safely traverse the obstacle without causing damage to the obstacle or the construction equipment.
