Case Study: Apply a new hoist control, safety controller and brake regulator to an existing hoist

Requirements: Design and supply an upgrade to the existing hoisting plant requiring new hoist control, electronic Lilly, brake regulator and new operator interface HMI. The hoist control needed to be integrated with an existing AC wound rotor control for service duty.

The hoist control panel, Safety Cube and brake regulator panels were integrated into one panel group to minimize on‐site wiring and to meet the limited space available.

The new console included two large touch‐screen monitors for increased functionality and ease of operation.

A maintenance computer was provided with long term data logging as well as diagnostic software with detailed troubleshooting capabilities.

Case Study: Incorporate an upgraded brake and hoist control into an existing hoist

Requirements: Design and supply an upgrade to the existing hoisting plant requiring new hoist control, electronic Lilly, brake control with new hydraulic supply and a new operator’s console. The hoist control needed to be integrated with an existing AC wound rotor control for automatic skipping.

The hoist control panel and the new Safety Cube panels were integrated into one panel group to minimize on-site wiring and to meet the limited space available.

The new hydraulic supply incorporated submersible pumps to satisfy a reduced footprint and also provided quieter operation – filtration, temperature control and system monitoring was improved.

The new console included two large touch-screen monitors for increased functionality and ease of operation.

Case Study: Replacement of MG Set with New Drive and Hoist Control

Requirements: Outdated technology replaced and upgraded to an existing hoist ‐ limited time for change over and limited space, motor needed to be sent out for refurbish during the shutdown.

A new digital drive was engineered and specified for the duty requirements. To satisfy the limited space and shutdown constraints, a mezzanine was constructed above the existing power and control cabinets and the new installation was completed and pre‐commissioned, ready for a quick switchover from old to new. Downtime for the change, including final commissioning was less than two weeks, during which the hoist motor was removed and sent out for refurbish (4 days).
