Patent number: 10844550Abstract: A workhead assembly for use in rail applications may comprise a frame and two pairs of workheads, wherein each pair of workheads is disposed on opposing sides of the frame and carries tamping tools. The workhead assembly may further include two vertically-oriented actuators being disposed on opposing sides of the frame. Two pairs of linkage arms are coupled between the vertically-oriented actuator and a pair of tamping arms. Each pair of linkage arms are disposed on opposing sides of the frame. Actuation of the linkage arms imparts movement to the tamping tools.Type: GrantFiled: September 12, 2018Date of Patent: November 24, 2020Assignee: HARSCO TECHNOLOGIES LLCInventors: Victor Vargas, Rob Alford, Reza Sami

Patent number: 10787771Abstract: The present disclosure relates to a rail vehicle having a track stabilization unit for use in stabilizing rails into ballast. The rail vehicle comprises a frame and a track stabilization unit coupled to the frame. The track stabilization unit includes a base and a plurality of wheels disposed about the base. The wheels are configured to bias against rails of a railroad track. At least one of the wheels is coupled to a motor through a drive shaft such that rotation of the drive shaft drives rotation of the wheel. Related methods are described.Type: GrantFiled: August 2, 2017Date of Patent: September 29, 2020Assignee: HARSCO TECHNOLOGIES LLCInventors: Victor Vargas, Syed Reza Sami, Eric Carter
