The system of claim 1, wherein the magnet is a permanent magnet.ġ1. The system of claim 1, further comprising a vibratory device for vibrating the railroad track in the region of the fastener.ġ0. The system of claim 1, further comprising an arm moveable over the surface of the magnet to facilitate release of a fastener magnetically attached to the surface of the magnet.ĩ. The system of claim 1, further comprising a vertical positioner, the magnet coupled to the vertical positioner for raising and lowering the magnet relative to the tie plate.Ĩ. The system of claim 1, wherein the surface of the magnet is a rectangle having a length parallel to the rail of about 8 inches and a width perpendicular to the rail of about 3 inches.ħ. The system of claim 1, wherein the tie plate and rail are fastened to the cross-tie by two fasteners located on the same side of the rail, and the surface of the magnet extends above both fasteners.Ħ. The system of claim 1, wherein the fastener has a head that projects above the tie plate, and surface of the magnet is about 2 inches above the head of the fastener.ĥ. The system of claim 1, wherein the magnet has a pull force on the fastener in a range of about 50 lbs to about 200 lbs.Ĥ. The system of claim 1, wherein the magnet has a pull force on the fastener in a range of about 50 lbs to about 1000 lbs.ģ. A system for detecting a spike killed cross-tie in a railroad track having a tie plate and rail fastened to the cross-tie by a ferromagnetic fastener driven into the cross-tie through the tie plate, the system comprising:Ī magnet positioned above the fastener and having a surface for magnetically engaging the fastener, the magnet having a pull force on the fastener of at least about 50 lbs.Ģ. Imaging tomography apparatus with out-of-balance compensating weights in only two planes of a rotating deviceĪcoustic sensing device, system and method for monitoring emissions from machineryġ. SHOCK AND IMPACT TESTING DEVICE AND METHOD HYDROGEN CONCENTRATION SENSOR UTILIZING CELL VOLTAGE RESULTING FROM HYDROGEN PARTIAL PRESSURE DIFFERENCEĮxternal Sensing Device for Machine Fluid Status and Machine Operation Status It’s designed to run at both 5 GPM and 10 GPM to provide enhanced flexibility and control. Shop for other railroad tools and equipment today.PHYSICAL QUANTITY DETECTION DEVICE, PHYSICAL QUANTITY DETECTOR, ELECTRONIC APPARATUS, AND MANUFACTURING METHOD OF PHYSICAL QUANTITY DETECTION DEVICE Using an efficient design, operators can grab the spike from either side of the rail with no need to reposition – then automatically pull the spike and drop it at the top of the stroke using a single motion.Īll moving parts are fully enclosed for safety, and the jaws of the spike puller can be changed as needed in minutes at the worksite without special tools – making it an ideal tool for all field operations. The design also incorporates a safety trigger, which eliminates the risk of accidental activation. ![]() It uses a safe, two-speed design which grabs the spike at a slow speed, which helps to avoid the jerking motion common among other spike pullers in use for railroad operations. It’s built to generate 13,000 pounds of pulling force, ensuring that even the most stubborn spikes can be removed without trouble. It enables operators to remove spikes quickly, safely, and efficiently from railroad ties. This Hydraulic Spike Puller by Matweld is a powerful tool for routine maintenance-of-way operations.
