Limited Yard Space – RTG Height Increase Solution

To overcome container congestion issue in the yard, we can effectively increase the yard capacity from 17% to 20% by simply raising RTG lifting height.

The cost for height increase ranges between $100,000 to $125,000 depending on the quantity and location of RTGs.

Preparation for site work may take from 4 to 6 month. Estimated  site work duration is 3 to 4 weeks for one RTG.

Installation of RTG gantry equaliser bushings

  • No bush was used in as-built design of many RTGs. Due to long utilisation in operation, especially at uneven gantry lanes, wear and tear are observed on both pin hole and equaliser pin. It creates gantry alignment issues.
  • Repair process is tedious for such design. It usually requires new pin and boring works at pin holes.
  • For refurbishment work, bushes, as shown in photo, are proposed to use to minimise the repair work in future.
  • Selection of suitable type of bush and installation design is very critical.
  • Portek has successfully accomplished such refurbishment works on many RTGs.
