General repair to 3-Stage compactor cylinder

Scope of work:

Cylinder tube for 3 stage compactor cylinder, inspected after strip down of the cylinder.

Rod stage 1 – Linished and ready for reassembly into cylinder tube.

Rod stage 2 & 3 – Linished and ready for reassembly into stage 1 rod assembly.

New piston manufactured for Stage 1 rod assembly.

New piston installed on Stage 1 rod assembly. Held in long 6-meter lathe for final inspection and dimensional checks.

Final Linish to remove any machining details.

Main trunnion mounted cylinder tube prepared ready for installation of Stage 1 rod assembly. All new seals and wear strips installed. Stage 1 rod also Stage 2 tube because of the telescopic design.

All new 12.9 High tensile socket head cap screw installed Insertion process of Stage 1 rod assembly into the main cylinder body.

Each Cap screw is cross torqued, and wax pen marked for QA inspection.

Final assembly – Stage 2 & Stage 3 rod assemblies installed awaiting QA checks. all fasteners torqued and wax marked.

All dimensional checks carried out to confirm closed specification.

Full extension – 17.5M during the function test and pressure testing at 2000 PSI The cylinder is supported by the gantry crane and scissor lift to prevent deflection to the rod assemblies during full extension.

Result:

Final testing and dispatched back to site for reinstallation and commissioning.
