There is disclosed a machine for crimping a coupling onto the end of a hose over which the coupling is coaxially fitted. The hose and coupling are inserted through an annular crimping head and positioned on a coupling support. Two semicircular arrays of circumferentially spaced-apart crimping dies are respectively carried by two pivotally mounted part-cylindrical die-holding jaws which open to facilitate insertion of the hose and coupling and close to form a circular array of dies surrounding the coupling, each die being radially slidably movable with respect to the associated holding jaw. As a hydraulic drive cylinder draws the crimping head toward the dies, cam means close the die-holding jaws and the crimping head then moves into surrounding camming engagement with the dies for moving them radially inwardly into crimping engagement with the coupling. A safety valve limits the force applied to the crimping head until the die-holding jaws have closed.

Manually-operated field apparatus is disclosed for applying a pressed-on coupling to the end of a hose. A frame carries two threadedly-adjustable sets of interleaved clamping plates for clamping a hose end therebetween in a predetermined orientation. The frame defines a pair of tracks on opposite sides of the hose parallel thereto, on which are respectively slidably mounted two runners of a coupling carriage for supporting the coupling between the runners coaxially with the held hose end. A manually-operated ball-type screw and nut assembly mounted on the frame is engageable with the coupling carriage for moving it along the tracks toward the hose end for pressing the coupling onto the held hose end.
