摘要： Embodiments of the invention provide a ram assembly for a hydraulic tool. The ram assembly includes a ram piston having a ram cavity. The ram piston receives a hydraulic pressure reaction force. The ram assembly further includes an overload assembly disposed in the ram cavity or in a cavity defined by a manifold. The overload assembly includes a burst disc positioned at a first end of the ram cavity or manifold, a lock nut positioned at a second end of the ram cavity or manifold, and a spacer positioned between the burst disc and the lock nut. The spacer transfers a supporting force applied to the lock nut to the burst disc. The hydraulic pressure reaction force and the supporting force both act in the same direction, and thus, are additive forces acting on the burst disk.

摘要： When a male member is inserted into a female member to connect a first joint portion of a hydraulic joint structure and a second joint portion thereof, a first open end portion of a first oil passage of the male member and a first open end portion of a first oil passage of the female member are connected at a first axial position, and a second open end portion of a second oil passage of the male member and a second open end portion of a second oil passage of the female member are connected at a second axial position. Thus, two hydraulic oil lines can be easily connected at the same time.

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.

摘要： A multiple tool attachment system is adapted to be attached to demolition equipment. The system includes a universal body attached to the demolition equipment. A series of tools is independently attachable to the universal body. The universal body includes a guide slot extending longitudinally along the universal body. Each tool generally includes a pair of pivotable jaws adapted to be pivotably attached to the universal body with at least one linkage extending from the universal body and attachable to each jaw of the tool. A slide member is received within the guide slot, with each linkage attached to the slide member, and a piston cylinder arrangement is attached to the universal body and coupled to the slide member for moving the slide member and the jaws. The multiple tool attachment system is provided with quick change features and is designed to optimize the cutting characteristics throughout the movement cycle.

摘要： Article breaking apparatus for mounting on an arm of a suitable vehicle, the apparatus having a pair of hydraulically operated jaws (12, 24), the first jaw (12) of the pair having first and second mutually perpendicular article supporting surfaces (14, 16) and the second jaw having an article engaging surface (26). The jaws (12, 14) are movable about a first pivot axis (22) between an article receiving position in which the first article supporting surface (14) and the article engaging surface (26) diverge away from the first pivot axis (22) and an article breaking position in which said surfaces (14, 26) diverge towards the first pivot axis (22). When an article (82) is located between the jaws (12, 24) and the jaws (12, 24) move from the receiving to the breaking position, the article (82) will be urged towards the second article supporting surface (16) and held there against until broken by the relative movement of the said surfaces (14, 26).

摘要： An article breaking apparatus for being mounted on an arm of a vehicle, and including a first member having a first jaw on a first end thereof and a mounting attachment on a second end remote from the first jaw for permitting the apparatus to be mounted onto the vehicle arm. The first jaw includes an article-supporting surface. A second member is pivotally mounted for movement about a first pivot axis, the second member including a second jaw having an article-engaging surface cooperable with the article-supporting surface of the first jaw and defining an article receiving opening therebetween. The second jaw is movable about the first pivot axis relative to the first jaw between an article receiving position in which the article-supporting surface of the first jaw and the article-engaging surface of the second jaw diverge away from the first pivot axis and an article breaking position in which the article-supporting and article-engaging surfaces diverge toward the first pivot axis. The article-supporting surface of the first jaw is inclined relative to the first pivot axis, whereby, as the first and second jaws move from the article receiving position to the article breaking position, an article located between the first and second jaws will move along the article-supporting surface of the first jaw towards the first pivot axis by the movement of the second jaw against the article relative to the first jaw. The jaws are moved by a hydraulic piston and cylinder assembly. The apparatus is particularly useful for breaking railway rails.
