Abstract: A pry bar sliding fulcrum assembly having a fulcrum and a saddle which slidably mate with a conventional pry bar and which provide a greater force onto a work material than the conventional pry bar alone. The pry bar sliding fulcrum assembly easily and quickly slides away from the work material when a conventional pry bar function is desired and slides toward the work material when an enhanced application force or greater pry bar end displacement is required. The assembly uniquely mates with or is held with the pry bar end whereby the assembly retains a static position relative to the pry bar during use.

Abstract: A rodding assembly containing a body, a first wing projecting outward from a first side surface of the body and extending at least partially along the length of the body, a second wing projecting outward from the second side surface of the body and extending at least partially along the length of the body, at least one spring loaded mechanism attached to an upper surface of the body, and a rod assembly attached to a rear surface of the body.

Abstract: A hybrid wedge jack/scissor lift device for lifting heavy loads is provided, the device having a horizontally-oriented actuator coupled to a wedge that acts on lower and upper rollers coupled to a scissor lift. In operation, the actuator can drive the wedge in between the rollers, spreading them apart to raise the scissor lift. When the actuator retracts, the wedge is removed and the scissor lift collapses under the weight of the load. The wedge can be shaped in such a way that the lift has one or more intrinsically safe positions in which the rollers on the scissor lift fit into seats on the wedge, preventing the scissor lift from collapsing in the event of an actuator failure. An optional restraint bar safety mechanism is also provided.
