Method, Apparatus and System for Lifting Railroad Structures
20210317615 · 2021-10-14 ·

A system and method for use in raising the height of railroad structures. Railroad structures are defined as the structures where two or mor railway tracks merge, cross, or divide. The method utilizes excavating an opening beneath a railway track at or adjacent to a railroad structure. A hydraulic jack is positioned within the opening. This is repeated until sufficient hydraulic jacks have been positioned around the structure. The hydraulic jacks are then actuated to raise the railroad structure to a desired height. Generally this height provides a slight crown to the structure. Ballast is then positioned beneath the raised railway. The hydraulic jacks can be disconnected from the hydraulic lines and left in position, or removed. Preferably the hydraulic jacks are positioned on hydraulic jack sleds for improved ease in transporting the hydraulic jacks and to provide a platform on which the hydraulic jack is slid into and out of the opening beneath the railway. An apparatus is provided for use in raising a railroad structure. The apparatus utilizes a hydraulic pump and motor positioned on a frame. Hydraulic fluid is selectively provided through a manifold to the hydraulic jacks, or to one or more remote manifold(s) either directly or through the manifold. Hydraulic jack sleds are provided that are preferably configured for storage and transport on the frame.

THERMAL LOCKOUT FOR A MOTOR OF A GATE CROSSING MECHANISM
20210262172 · 2021-08-26 ·

Examples described herein provide a computer-implemented method for thermal lockout for a motor of a gate crossing mechanism. The method includes monitoring a motor current across a sense resistor of the motor. The method further includes determining a present thermal capacity unit (TCU) at a time interval based on the motor current across the sense resistor. The method further includes determining whether the motor is at a thermal limit by comparing the present TCU to an expected TCU. The method further includes responsive to determining that the motor is at the thermal limit, causing initiating a hard fault.
