The multi-use flat bar includes a generally L-shaped body, which has a long leg and a short leg. The body also has a pair of side edges that extend along a full length of the body including both the long leg and the short leg. The long leg of the body has a first surface that is provided with angle measuring indicia, which includes a plurality of lines that extend from one of the side edges and point towards an opposite side edge in the short leg of the body.

A spike puller apparatus comprises a subframe, a pair of opposed puller arms for engaging with spikes to be pulled via a replaceable puller tool mounted on the end of each puller arm, a pair of horizontal shafts and an actuator to selectively translate each puller arm with respect to one another, an actuator to articulate each respective puller arm for pulling spikes, an A-frame connected to the subframe to resist and/or apply pulling forces to a spike being pulled, and a vertical actuator connected to the A-frame to cause the vertical slide carrier to move up and down along the pair of vertical shafts to effect a spike pulling operation. The respective puller arms are independently controllable, and may be selectively staggered with respect to one another along a rail to allow selective independent and/or simultaneous pulling of rail spikes and/or anchor spikes on opposite sides of the rail.

A portable railroad spike remover comprises an extractor that is shaped to engage and secure a railroad spike previously installed into a rail tie. A drive shaft is connected to the extractor such that as the drive shaft is rotated, the extractor is vertically raised and lowered within a main column. The extractor may have an opening extending through at least one side to engage the railroad spike.

Method and systems of automated document processing described herein include activating in sequence a plurality of illumination modules of an illumination source to illuminate a document, where the plurality of illumination modules are located at different positions relative to the document. The document can be imaged each time the document is illuminated by an illumination module to provide a plurality of images. A shadow profile of the document can be obtained based on the plurality of images. One or more of a boundary of the document and presence of a fastener attached to the document can be identified using the shadow profile. Any fasteners present may be removed using a robot arm.

An apparatus is selectively controlled to insert a check pin into a fastener hole in a workpiece surface and remove the check pin from the fastener hole. The apparatus is a pneumatically actuated apparatus having a pair of press actuators that are selectively operated to press the check pin attached to a check pin holder of the apparatus into a fastener hole in a workpiece, and a pair of remove actuators that are selectively operated to push against the workpiece surface and move the apparatus away from the workpiece surface to remove the check pin attached to the check pin holder from the fastener hole in the workpiece.

A shaft, a wedge and a fulcrum plate connecting the shaft and wedge and having a transverse cross-section in one plane narrower than the shaft and a cross-section in an orthogonal plane wider than the transverse cross-section.

The broom head with nail puller attachment comprises a body, a plurality of bristles, a nail puller, and a plurality of magnets. The broom head with nail puller attachment may removably couple to a broom handle to form a broom. The broom may be operable to sweep a floor when placed into a sweeping orientation and pushed along the floor. The nail puller may be operable to remove nails from the floor when placed into a nail-pulling orientation and rotated using the broom handle to pry the nails. The plurality of magnets located within the body may be operable to collect and retain the nails or other metallic debris. In some embodiments, the body may comprise a magnet cover to protect the plurality of magnets from becoming contaminated by the metallic debris.
