Alatas Middle East was called by Alatas UK to conduct a Liebherr MTC crane inspection and troubleshooting of jerky slew performance on a MTC 2600-100 installed on a jack-up ship in Great Yarmouth. The bad performance was due to a big radius.
Job Scope Liebherr MTC Crane Inspection
- Mobilisation from Vienna to Great Yarmouth Port
- Discussed with the persons in charge of the safe procedure for inspection
- Carried out slew function test
- During this test lot of clearance in the slew gear carrier appeared
- For further investigation, upper bearing slides and the setting of the slew gear carrier had to be checked
- To receive proper measurements slew gearbox carriers had to be taken off
- Measured main pins and borings on all three carriers to inspect if clearances are still kept or if excessive wear caused the problem
- An excessive axial clearance on the guide rollers was found to cause the problem as spacer shims were missing completely
- Reinstalled shims and slew gear carriers
- Carried out settings as per manufactures procedure
- Carried out slew test with three different operators as the problem just came up intermittent
- Operators were satisfied with the performance of the slew and gearbox carriers remained steady during operation
