Refurbish In-Place Double Drum

Case Study: Refurbish Hoist Mechanicals In-Place

Requirements: The site required the complete refurbishment of an abandoned hoist in situ, underground.

Following the evaluation of the equipment, specifications for refurbish were developed to reflect the condition of each piece of mechanical and electrical equipment. The specifications reflected new regulations and industry practices for safety compliance.

Complete engineering for a new variable frequency drive, PLC control for the new digital drive with console.  Remote Access for troubleshooting was added. All refurbish work was completed with partial tear down and removal of the hoist.

Final duty for this hoist was for mine emergency escape.
