About the Project:

The project involved retrofitting MHC Winch Drum by accessing constricted space around the holding area. The success depended on achieving timely results while maintaining structural integrity that met all standards of quality.

Project Challenges:

The following challenges demanded on-the-spot problem-solving and specialized tools and skills:
• The project required dismantling the closing gearbox and the drum’s outer bracket, both of which were tightly integrated with surrounding structures.

• The removal of the holding drum from a confined space with limited accessibility posed a significant complexity.

The solution:

• Detailed pre-planning discussions and brainstorming sessions were held to ensure a smooth execution strategy to be completed within stipulated time frame.

• Designated team carried out a thorough risk analysis for enhanced safety measures.

• A structured daily activity plan was developed and followed meticulously.

• The removal of the closing gearbox was achieved using a fabricated puller and hydraulic jack system, ensuring minimal stress on components.

• For the drum’s outer bracket, a combination of hydraulic jacks, lifting belts, and crane coordination was used.

• The holding drum was extracted using a custom stand with sliding beams and a clear pathway to avoid obstruction.

• Installation of the outer bracket was done using a specially designed puller system, ensuring perpendicular positioning to the shafts and accurate alignment with bearing covers.

The results achieved:

MHC Winch drum retrofit work is completed successfully within the stipulated time period.
