Abstract: A dual-use, battery-operated rail lifting device for railway maintenance is disclosed. The device includes a two-piece housing assembly and an internal lift mechanism actuated by a battery-powered electric drive unit coupled to a screw threaded rod. A lifting L-shaped structure extends vertically from ground level to raise and stabilize a running rail segment without manual lifting or hydraulic systems. The rail lifting device may be ergonomically configured for waist-level operation, reducing torsional stress and back injury risk, while increasing stability, load capacity, and durability. The design may be adaptable to various rail sizes, lightweight, and operable with either an integrated motor or a detachable off-the-shelf impact drill, thereby simplifying field operation in remote railway environments.

Abstract: The present invention relates to a railroad spike stabilizer for railway and construction applications. The stabilizer comprises a hollow, square-based prism body with four outer walls defining an internal cavity conforming to a railroad spike's geometry. The cavity, open at the top, tapers inward with angled inner walls. Segmented, flexible legs extend from the bottom, compressing and expanding to engage the tie plate hole, with clips locking the stabilizer. Flexible ribs adapt to hole variations, and a visual alignment guide ensures orientation. A spike and plug stabilizer embodiment includes a ribbed or finned plug for pre-existing holes, enhancing spike stability and reducing fatigue compared to wood plugs or polyurethane foam. The stabilizer improves alignment, reduces spike fatigue, minimizes worker injuries, and enables single-worker operations.

Abstract: A dual-use battery-operated portable grinder is utilized for the railway industry, specifically for grinding the web of railroad rails post-welding. The battery-operated portable grinder can be employed in a hand-held configuration or seamlessly integrated with a quick-connect mechanism onto a specialized frame device, serving as both a support structure for the grinder and a means for reducing worker strain by eliminating the need for bending. The battery-operated portable grinder may include: battery-powered operation, a robust brushless motor, a built-in handle-incorporated base portion for safeguarding the motor from potential damage, a lightweight design, an anti-vibration handle to alleviate operator fatigue and ensure proper balance during usage, a reinforced shaft to enhance operational durability, improved grinding wheel stability to minimize vibration and wear during use, and its versatility in performing rail head and web grinding tasks.
