Abstract: There is disclosed a structure for fastening a shipboard-protecting fender comprising: a plurality of reinforcing rib layers securely provided on the inner and outer faces of a shipboard; a fixed base horizontally fastened on the reinforcing rib layers of the shipboard by means of a plurality of bolts, an accommodating space being formed at the outside of the fixed base; a core layer, one end of which is accommodated in the accommodating space of the fixed base; a bump-preventing layer covering the outer surface of the core layer and the fixed base; a pair of fixed plates supported at the outside of the two ends of the bump-preventing layer; and a plurality of bolts vertically passing through the fixed plates, the bump-preventing layer, the fixed base, and the core layer for fastening them, in which the bump-preventing layer is made from polyurethane (P. U.) material, while the core layer is made from the close cell of ethylene-vinylacetate copolymer (E. V.

Abstract: A clamping device for carrying barrels having end frame rims is supported on a housing adapted to be lifted by a fork lift truck. Upper and lower clamping heads carried by a parallelogram link mechanism pivotally supported on a bearing holder mounted at the upper end of the housing are normally urged upwardly to a released position by a counterweight carried by one of the links which comprise the link mechanism. When the lower clamping head is engaged with the rim of a barrel and the housing is elevated by a lift truck the parallelogram linkage moves the upper clamping head downwardly toward the lower clamping head against the action of the counterweight and into cooperating clamping relation to the lower clamping head to grip and hold an upper portion of the barrel.
