Abstract: A chain tensioner is provided with a take-up hook (21) connected to the junction area (30) between the shank (3) thereof and double hook end (4) by means of a chain (20). The take-up chain (20) has an end link (23) surrounding the shank material of the tensioner and which is bound by its form between the shank portion (23) on one side and material projections (22) on the flattened end portion (4). The link (23) surrounds the junction area (30) with clearance so that the link (23) can be swung relative to the direction of the shank (3). The link (23) connecting the take-up chain (20) to the tensioner is to advantage made in a C-shape so that the take-up chain (20) with hook (21) can be easily hooked-on to or hooked off the tensioner.

Abstract: A coupling device for container lashings comprises two tensioning members (1, 3; 11, 13) having coacting teeth (2, 12) and a clamping means (20) for keeping the members with the teeth (2, 12) in mesh. One flank of the teeth (2, 12) inclines at an angle (.alpha.) of between 95.degree. and 110.degree. to the tensional load direction (r) of the member. The other flank of the teeth inclines at an angle (.alpha.) of between 30.degree. and 50.degree. to the tensional load direction (r). The clamping means (20) is an eccentric clamping collar, surrounding the members (1, 11) in their toothed zone and in an open condition affording a clearance (s) between the top land planes of the elements (1, 11) in the same order of magnitude as the tooth depth (t) but in a closed condition the collar (20) maintains the teeth (2, 12) of the members in mesh. Each of the members have means (4, 14) against which a tensioning apparatus (30), e.g. a hydraulic tensioner can be applied.

Abstract: A lashing rod for lashing vertically stacked containers. The containers have hollow corner castings and the lashing rod has a head comprising a stud adapted for passage through a side access opening of the casting. The locking head is securable to the casting by rotating the head about a pivotal axis so that the stud engages an inner wall of the casting. A fitting, having a locking pin receiving bore, partially extends into a corner casting and is adapted for interconnecting two abutting stacked containers. The locking head has a locking pin adapted for insertion into the bore upon passage of the stud into the side access opening so that the locking head is rotatable for securing the locking head to the casting while the pin is inserted in the bore.
