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. Also provided are several features for facilitating the compatible mountability of the take-up assembly with respect to the lift truck, including a built-in pressure-relief system for protecting the fluid lines and load-handling attachment served by the fluid lines from any excessive pressures which might otherwise result from the design or operation of the lift truck\s hydraulic system, an improved line-coupling device for attaching the forward ends of the fluid lines to the lift truck carriage with less likelihood of leakage or interference with mast structure, and a reversible retracting spring.

In a take-up assembly for a flexible fluid line comprising a journal member having a first fluid passage therein, a line connector mounted on said journal member for rotation about an axis of rotation and having a second fluid passage therein communicating with said first fluid passage so as to form a rotary fluid coupling, said line connector having line attachment means for detachably connecting said fluid line to said line connector, and a reel mounted on said journal member for rotation about said axis of rotation, said reel including respective first and second line-enclosing flanges disposed opposite to and axially spaced from each other and a line-storing hub extending axially between said flanges about which said fluid line is collected in windings, the improvement which comprises respective first and second line-supporting surface means on said hub having axially-extending widths traversing substantially the entire distance between said flanges for supporting said windings of said fluid line, and means detachably connecting said first flange to said line-storing hub for permitting removal of said first flange therefrom while permitting the retention of substantially the entire width of said first line-supporting surface means on said hub, said second line-supporting surface means being located adjacent said line attachment means and being axially removable from said hub and from said first line-supporting surface means upon detachment of said first flange from said hub for facilitating access to said line attachment means. In a take-up assembly for flexible line comprising a journal member, a line connector mounted on said journal member for rotation about an axis of rotation, a reel mounted on said journal member for rotation about said axis of rotation, said reel including respective first and second line-enclosing flanges disposed opposite to and axially-spaced from each other and a line-storing hub extending axially between said flanges about which said line is collected in windings, and a helical spring assembly mounted against one of said flanges for urging rotation of said line-storing hub, the improvement which comprises a plurality of elongate connectors, each extending through both of said flanges and said line-storing hub and being connected to said helical spring assembly, and each detachably interconnecting each of said flanges, said hub and said helical spring assembly with respect to one another.
