Case Study: Increase in Braking Capacity

Requirements: Our customer was facing increasing demands from their hoist which, in its existing configuration, the braking capacity was not going to be able to meet the demands.

The system in place included bulky brake weights and there was limited space available for any new equipment.

The solution included the design of new drum brake calipers, brake posts and tie rods. The brake weights were replaced with new spring packs with hydraulic release system with an increased braking capacity for the hoist.

The brake assembly was fully assembled to prove a test fit in the shop before being released to the customer.

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.
