ABSTRACT OF THE DISCLOSURE An actuatable member of a pintle assembly is slidably movable along an axis for movement relative to a reel-carrying cradle support member between reel engaging and disengaging positions. Compression springs are used to urge the actuatable members of the illustrated embodiments toward the reel-engaging positions. Locking devices, which can move between locking and releasing positions, are each arranged to directly cooperate and block the movement of an actuatable member to a disengaging position thereof in the locking position of the locking device. The locking devices may include blocking elements such as rigid displaceable balls or pins, or may include cam arrangements and the like. A fluid pressure system is provided to act at least on the locking devices and release the same when fluid pressure is applied. Advantageously. the fluid pressure system also acts on the actuatable member to move the same to the reel disengaging position upon release of the locking device. The described embodiments provide fail-safe operation during reel engagement independently of the fluid pressure provided by the fluid pressure system.
