A battery-operated tool is disclosed for use in the rail industry. In some embodiments, the battery-operated tool may comprise a battery-operated spike driver configured to drive in spikes configured to hold rails for a railway onto a fixed point. The battery-operated tool may include or otherwise be connected to a battery management system. The battery management system may be configured to manage the power supplied to the battery-operated device via one or more batteries. In various embodiments, the one or more batteries may comprise a set of rechargeable batteries connected in series or in parallel. In some embodiments, the battery management system may be attached to or included within the battery-operated device. In other embodiments, the battery management system may be physically separate from the battery-operated device. For example, the battery management system may be included within a separate battery pack that includes the set of batteries.

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.

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.

A system and method for automating railroad maintenance for a tie gang using electronic tie marking (ETM) configured to optimize railroad asset maintenance. The system enables the automating of an adaptive maintenance process for the asset that is being maintainanced. The system can identify a railroad asset scheduled for maintenance using various forms of inspection including real-time kinematic (RTK)-corrected GPS data, radar signal processing data, and real-time imaging. The system also provides for the acquisition and upload of asset pictures for verification and analysis of a railroad asset. The system can identify a next location to perform maintenance and can calculate an optimum path based on sensor input incorporating machine-specific and environmental characteristics. The system further can provide a customizable user interface to identify, track, and process information related to maintenance of the railroad asset.
