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. An electric drive unit electrically operates the linear displacement unit. A method for pulling a railroad spike of a track is also provided.

A threaded pin remover for a threaded pin in an interference fit in a structure is provided. The threaded pin remover includes a housing. A pin grasper is slidably mounted in the housing and includes: a first end configured to couple to a linear actuator for slidably moving the pin grasper between an extended position relative to the housing and a retracted position relative to the housing. A second end of the pin grasper includes a pin grasping collet configured to, in the retracted position relative the housing, engage with a portion of the housing to cause grasping of the exposed portion of the threaded pin by the pin grasping collet to release the threaded pin from the interference fit, allowing removing of the threaded pin from the structure.

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.

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.
