Abstract: A take-up assembly for storing and selectively feeding and taking up flexible line, usually hydraulic hoses, extending between the body or mast of a lift truck and the vertically-reciprocating load carriage of the truck. The take-up assembly includes disassembly features for facilitating servicing of the take-up assembly and flexible lines while mounted on the truck and further includes external seal features for protecting its internal fluid seal structure from contamination and thereby improving its durability without permitting such external seals to add substantial rotational drag to the take-up assembly.

Abstract: A fluid cylinder assembly comprising a cylindrical shell and movable plunger member having an annular retainer internally threaded into one end of the shell so as to limit the extensibility of the plunger from the shell, such annular retainer being specially designed so as to enable the outside diameter of the shell to be minimized without adversely affecting the performance of the cylinder assembly. The resilient fluid seal between the retainer and the shell, normally located at a position interior of the retainer threads, is instead located exterior of the threads at the end of the shell. The retainer includes a radially-projecting flange portion, exterior of the end of the shell, having a chamfered annular recess therein which encloses the end of the shell and resists any tendency of the end of the shell to expand radially when the force of the plunger is imposed upon the retainer by prestressing the flange against such expansion.
