A tunnel relief device includes an arcuate frame member, at least two fire-extinguishing arms, and a transport assembly. The arcuate frame member traverses along a length of the tunnel via first guide rails positioned on an inner surface of the tunnel. The fire-extinguishing arms are positioned on an inner surface of the arcuate frame member and traverse along the inner surface of the arcuate frame member via second guide rails to extinguish fire induced in the tunnel. The transport assembly comprises extendable arms and housed in an upper region of the arcuate frame member. The extendable arms are movable in a horizontal or vertical direction. The transport assembly is rotatably engaged to the upper region of the arcuate frame member to transport the vehicles in the tunnel from a first position to a second position to ensure safe and unobstructed movement of the vehicles in the tunnel.

A lift bail assembly includes a lift bail frame, two distal lift clamps, two or more proximal lift clamps, and two stops. The lift bail frame includes an attachment cutout to attach the lift bail frame to a lifting device. The lift bail frame extends at least half of a body length of the unmanned underwater vehicle (UUV) where at least of a weight of the UUV is directly supported by the lift bail. The two distal lift clamps are positioned opposite each other at each end of the lift bail frame. The two or more proximal lift clamps are positioned anywhere on the lift bail frame between the two distal lift clamps. The two stops fit into two stop cutouts on the UUV and are centered on the lift bail frame. All lift clamps that encompass the UUV are rigidly fixed to the lift bail frame.

A drive unit for at least one traction means, especially in stage machinery, with a winding drum comprising at least one take-up region, on (each of) which a traction means is received which can be wound up or unwound, characterized in that axially adjacent to the take-up region there is a cylindrical drive region disposed on the winding drum, on which is received a belt-shaped drive means that can be wound up or unwound and which can be wound up onto a drivable drive drum, generating a drive torque acting on the winding drum, or can be unwound from the drive drum, releasing the winding drum.

The disclosures contained herein pertain to an improved recreational-cargo-securement strap that is especially adapted for use as a utility strap for the management of watercraft, such as a raft, and features three strategically disposed equipment-engagement loops.
