11. Carry out spot checks of rail grinding on at least 5% to 10% of grinding locations as a follow up to the grinding operation . 12. Investigate variations to the designed contacts and report major anomalies to the Chief Engineer Track. For turnout grinding: 1. Visually assess rail condition before grinding .
5.1 The equipment must have sixteen stone grinding capability or greater. Production rail grinding services can be expected on the entire WMATA rail system to include revenue tracks, pocket tracks, interlocking, connector tracks, yard lead
30/10/2020· Rail grinding is one effective technique of railroad track repair and maintenance. By using rail grinders, rail defect material is removed and the rail profile is restored. Thus the service life of railroad track is extended. Rail defects. When talking about rail grinding, the rail defects are needed to be introduced first.
open rail grinding should be used for this special operation. 2.14 The machine shall also be capable of grinding, if required, only one of the rails of the track as in the case of curves. 2.15 The machine shall be capable of grinding profile of UIC 60 Kg rail section, 52 Kg and 90 R
applying grinding techniques to achieve rail profile and surface condition to meet requirements of rail industry standards and procedures; applying relevant safeworking system and workplace procedures; grinding welds and weld repairs using appropriate grinding wheel speed and rate of
04/01/2014· The rail grinding contractor must measure six points on each rail after grinding; only one may be outside the specified value of 10 microns. While the recording frequency is not specified, it is typically done once per grinding shift.
Identify rail grinding job requirements . 2.1 . New welds and weld repairs are located. 2.2 . Hazards are identified, risks are assessed and control measures are implemented. 2.3 . Appropriate grinding equipment is selected and checked for correct operations in accordance with workplace procedures. 2.4
RAIL GRINDING/MILLING SERVICE REQUIREMENTS 4.1. The Service shall be carried out continuously with Grinding/ Milling System on both rails simultaneously along the place where the service shall be performed. The Grinding/Milling shall be carried out, without adversely affecting the metallurgical
Each grinding operation has its unique requirements, and Harsco Rail focuses on developing a machine that will ensure a successful grinding operation in every application.
Profile Grinding Goals. Top of rail should never have a radius less than 8. Reduced running band can result in high stresses and rail surface fatigue Running band should be between 1 1/4 and 13/4 inch on all rails. Reduce plastic deformation and metal surface fatigue.
