A method for lifting a tank car is provided. The method can include positioning a lifting apparatus above a tank car, pulling at least one of the first arm and the second arm outward to place the lifting apparatus in an open configuration, lowering the lifting apparatus in the open configuration to surround a tank of the tank car, connecting the second end of the first arm to a first tank car support, connecting the second and of the second arm to a second tank car support, and raising the lifting apparatus to lift the tank car.

The present invention concerns a gripping device for gripping a packing section, having a support forming a chassis and retaining means connected to this support and distributed angularly so as to surround the packing section that is to be gripped, characterized in that at least one of the retaining means has movable shoes respectively intended to be in contact with a peripheral edge of the packing section and a plurality of platforms disposed in at least two stages, each platform bearing articulation means able to interact with a platform of a different stage or one of the movable shoes.

A gripping device for shells that includes a pair of jaws intended to clamp a shell, each jaw being able to pivot towards a closed position obtained by applying the top end of each jaw to the shell. A locking means links the top ends of the jaws and includes two connecting rods and a central segment linking these connecting rods. The connecting rods are articulated relative to the jaws by a first articulation and by a second articulation to the central segment. A spring links each first articulation to a central point of the segment. A movable stop situated above the locking means is capable of pushing the locking means downwards until it is below an unstable equilibrium position of the locking means.

A tong assembly for use with a work vehicle for grasping irregular shaped objects such as large rocks and smaller sized boulders. The tong assembly includes specially designed load engagement pads having a rectangular configuration of steel bars and attachable to the tong arms proximate their lower ends. A pair of the bars that extend parallel to one another, but normal to the tong arms have a serrated arcuate load engaging surface for enhancing the ability of the tong assembly to grasp and retain irregular shaped objects.

A lifting system for post frame construction comprises a winch system coupled to a frame, a first bracket configured to be secured to a portion of a roof framing system, and a pulley system comprising at least two pulley wheels mounted on a second bracket. The frame is configured to be secured to a lower portion of a column of a building structure and the second bracket is configured to be secured to a top of the column.

A gantry crane for a container includes a portal main frame, a traveling mechanism, a translation mechanism, a hoisting mechanism and a spreader assembly. The spreader assembly includes a spreader body, two telescopic girders and a drive assembly. The drive assembly includes a cam, a sliding way and two sliding blocks. Two arc-shaped first sliding grooves are circumferentially provided on the cam. A middle of the sliding way is rotatably connected with the cam. Two sides of connection of the sliding way and the cam on the sliding way are provided with a second sliding groove. Each sliding block matches with the first and second sliding grooves, and can slide back and forth along them. The telescopic beams are slidably connected to the spreader body, and are symmetrically provided and connected to the sliding blocks, respectively.

A load lifting device for lifting a load. The load lifting device includes a primary plate, a lifting attachment that receives a hook of an overhead suspender, and a clamping system that can clamp a load onto the lifting device between two jaws. The clamping system can have a coarse adjustment and a fine adjustment. The coarse adjustment selectively connects a jaw to the primary plate at a plurality of discrete connection points, and the fine adjustment mechanism selectively moves a contact point of the first jaw toward a first end portion of the load. A method for lifting a load includes positioning the load lifting device horizontally above a load, clamping the load with a clamping system, and imparting a vertical force on an end portion of the load lifting device to rotate it from horizontal to vertical.

Aspects herein are directed to a clamp having a linkage coupled to a first end of a first and second clamp member. Based on applying a first directional force to the linkage, the linkage generates a force that moves the second ends of the first and second clamp member towards one another, thereby biasing the clamp to the closed position. The clamp secures a strap when the clamp is in the closed position and releases the strap when the clamp is in an open position.

A system for pulling posts is disclosed. The system for pulling posts comprises a mast extending along a direction having a vertical component, an elongated arm rotatably and pivotably supported by the mast and extending at an angle relative to the mast, a pusher with first and second opposite ends, the first end of the pusher being configured to support the elongated arm at a first location of the elongated arm, and the second end of the pusher being configured to contact a ground surface, the pusher being configured to increase in length to drive the first location of the elongated arm away from a ground surface and thereby change the angle relative to the mast, and a pole attachment site at a second location of the elongated arm.
