Abstract: A conversion apparatus (10) for converting a vehicle (V) for travel on a railway comprises first and second assemblies (20, 20') connected by an axle (23). Each assembly (20, 20') comprises a first support member (11) rigidly mounted to the vehicle frame and a second support member (13) pivotally mounted to the vehicle frame. The second support member is coupled to the first support member for limiting the pivotal movement of the second support member relative to the vehicle frame. A pair of railway wheel support arms (18, 18') are pivotally mounted to the second support member (13) for movement between raised and lowered positions and carry a railway wheel (21) rotatably mounted thereon. A hydraulic cylinder (22) moves the railway wheel support arms between the raised and lowered positions.

Abstract: A quick release winch tie down assembly is mounted in the tracks of a ramp of a car hauler vehicle and includes a crank shaft extending from one end through a segmented bearing sleeve, a release shaft connected to said crank shaft in nonrotatable telescopic arrangement, and a tie down sleeve extending about both the release shaft and crank shaft in a space between the bearing sleeve segments. A spring urges lock elements of the tie down sleeve and the release shaft in locking relationship. A tie down chain is connected at one end portion to the tie down sleeve, and a rachet and pawl means limits the rotation of crank shaft to one direction, so that when the crank shaft is rotated it also rotates the release shaft and tie down sleeve and winds the tie down chain about the tie down sleeve, and when the lock elements are disengaged, the tie down sleeve is free to rotate and unreel the tie down chain.

Abstract: A two-stage double acting telescopic hydraulic cylinder includes two fluid ports formed in the external cylinder, one port for receiving fluid to distend both cylinder stages and the other port for receiving fluid to retract both cylinder stages. The cylinders are used in combination with car carrying trailers.
