A spike puller for pulling a railroad spike of a track includes a housing, a linear displacement unit mounted at the housing, and a claw unit for gripping the railroad spike. The claw unit is displaceable in a linear manner relative to the housing in a displacement direction by using the linear displacement unit. The linear displacement unit includes a hollow tube which is guided in the housing. A method for pulling a railroad spike of a track is also provided.

A nail-removing device operatively associable with a pneumatic nail driver, affording a method of improving the pneumatic nail driver. The nail-removing device has a shaft extending between a nail end and a driver end. The nail end provides an engagement portion for engaging the underside of a nail. The driver end provides a stabilizing interface configured to operatively associate with the pneumatic nail driver so as to prevent lateral movement of the pneumatic nail driver relative to the stabilizing interface. The engagement portion and the stabilizing interface may be spaced apart from the shaft in the same direction.

The present invention is directed to a handheld railway spike puller. The spike puller is adapted to operate for pulling of a railway spike from a sleeper and its associated sleeper plate. The spike puller is adapted for coupling with a rotational driver in the form of battery-powered impact wrench. The spike puller generally includes a housing assembly being generally elongate and at a proximal end adapted for detachable coupling with the impact wrench, a drive screw substantially housed within the housing assembly, and arranged for rotation via the impact wrench, a slide assembly including an internal thread configured to engage an external thread of the drive screw which on rotation in a forward direction and a reverse direction effects sliding movement of the slide assembly within the housing assembly between an extended position and a retracted position, respectively. The internal and external threads are designed on rotation of the drive screw in the forward direction to release from one another in the extended position of the slide assembly. Biasing means includes a spring operatively coupled to the drive screw. The biasing means is arranged on release of the internal and external threads to urge the slide assembly in the extended position axially toward the drive screw.

Embodiments of the present disclosure may include a nail removal system with a tube having an open end and a bore with an inner surface, a spring, and a gripping portion with a plurality of fingers. The tube may have a first position and second position. The gripping portion may have an opened position and closed position. The gripping portion may be in the opened position when the tube is in the first position. The plurality of fingers may be in the closed position when the tube is in the second position allowing the fingers to grip the head of a nail. The nail removal system may be operated manually, operated by a drill, or operated automatically using a robot. Advantageously, the nail removal system effectively removes a nail in a surface. A method of removing a nail from a surface using the nail removal system is also provided.

A staple removing device has a pair of levers pivotally coupled at one end on an axis such that their other ends are capable of movement toward one another. A bias spring acts on the pair of levers for biasing the pair of levers into an open position. A pair of extraction jaws on the other end of the pair of levers have engaging ends extending toward the other of the pair of levers for engaging the underside of a staple embedded in a material to lift the staple away from the material. A capture slot is formed one of the pair of levers that captures a staple when removed.
