摘要： The rescue spreading tool has a hydraulic cylinder (20) that produces a pushing and pulling action to pry open damaged vehicles at the scene of an accident. A stationary yoke (28) is attached to the cylinder and a pair of spreader arms (32) are also pivotally attached and are free to rotate in opposed directions. A pusher cam yoke (46) if formed integrally with the ram (22) within the cylinder and engages the arms pushing them apart when the ram is extended providing an initial cam action. A pair of toggle links (58) are attached on both the top and bottom of the arms and pusher cam yoke and continue to push the arms apart in an outward direction producing a secondary thrust after the initial cam action is completed spreading the arms to a maximum distance. When the ram is retracted the links close the arms through the secondary mode by reversing the procedure and continue to pull the arms together during the returning initial action, thereby completing the operational mode of the tool.

摘要： A hydraulic rescue tool (10) is comprised of a hydraulic thrust apparatus (20) consisting of a hydraulic cylinder body (24) having slots (28) within a hollow end and interlocking ears (36) protruding from the slots. A gland (38) is interfaced between the ears, with the gland and ears connected to the cylinder hollow end with threaded fasteners (98). A connecting link (50) is attached to each interlocking ear and a quick disconnect implement unit (22) is attached to each link and to a piston rod (30) within the cylinder body (24). Six dissimilar embodiments of implement units, each having quick disconnect capabilities and different vehicle structure separating utility are attached to the hydraulic thrust apparatus (20).

摘要： A hydraulic rescue tool (10) with a quick-change head (26) that incorporates a cylinder (20) having a piston rod (22) and a forward end structure (24). The forward end structure (24) has a separable head and a cylinder attaching bifurcated yoke (28). A pair of yoke quick release pins (48) jointly engage the head (26) and the bifurcated yoke (28) thus, creating an attachment therebetween. A pair of cutting blades (50) are connected to the head (26), and links (54) connect to the piston rod on a first end and to the cutting blades (50) on a second end, thereby forcing the cutting blades from an open position to a closed position by movement of the piston rod (22). A pair of link quick release pins (60) engage the links (54), creating an attachment therebetween, permitting the links to be released by manually disengaging the quick release pins, thereby allowing the head, including the cutting blades, to be rapidly removed or repaired.
