NOTE\u2003The 6six-monthly thorough examination may can be supplemented by NDT examination at the discretion of the competent person.
D.1.1.1G.1.1.1 Confirm the identification number of the frame and all corresponding sections, to confirmverify that all parts are of the same frame.
D.1.1.2G.1.1.2 Carry out a visual check of the frame structure, checking for any damage to structural members or evidence of cracking in welds. Pay, paying particular attention to the suspension brackets and the jointing plates.
D.1.1.3G.1.1.3 Confirm the free movement of all guide rollers and check for damage.
D.1.1.4G.1.1.4 Check the rollers for undue wear and check that all keep plates are in place and secure.
D.1.1.5G.1.1.5 Check the hydraulic ram mounting brackets for security, and check the welds for signs of cracking.
D.1.1.6G.1.1.6 Check the lifting yoke at the base of the hydraulic ram for signs of wear and any cracking or deformity.
D.1.1.7G.1.1.7 Check the hydraulic ram joint pin for lift and that it is correctly locked in position.
D.1.1.8G.1.1.8 Check that the rollers are free to rotate, to allow horizontal motion of the ram, are free to rotate. <\/td>\n<\/tr>\n
203<\/td>\nD.1.1.9G.1.1.9 Carry out a visual inspection to check that the hydraulic system is free from leaks and has no damage to the pipework or the connections.
D.1.1.10G.1.1.10 Check the travelling platform and its support for damage to itself and its supports.
D.1.1.11G.1.1.11 Check the walkways for damage and security of fixing. Close off the walkways.
D.1.1.12G.1.1.12 Record the results of the examination on the appropriate form and retain on file.
D.1.2G.1.2 Procedure for 2two-yearly thorough examination
D.1.2.2G.1.2.2 Remove the reaction roller pins and measure them to assess wear. Subject the pins to NDT examination.
D.1.2.3G.1.2.3 Carry out the six-monthly thorough examination at this time.
D.1.3G.1.3 Procedure for 4four-yearly thorough examination
D.1.3.1G.1.3.1 Subject the hydraulic ram and relief valves to a pressure test in accordance with the manufacturer\u2019s recommendations for thatthe system.
D.1.3.2G.1.3.2 Remove the ram-jointing pin, measure it for any wear and subject it to NDT examination.
