Engineering case study

Shaft signalling redesigned to restore compliant hoisting availability

Signalling failures on a hoisting installation were halting vertical transport. We rebuilt the signalling protocol and the compliance evidence behind it.

The challenge

Intermittent shaft signalling faults were causing unplanned hoisting stoppages, with no traceable inspection record to demonstrate statutory compliance.

Our approach

  1. 01

    Installation assessment

    Full winder and signalling installation inspection against statutory requirements.

  2. 02

    Protocol redesign

    Signalling protocol reworked with fail-safe logic and unambiguous shift-change handover.

  3. 03

    Modernisation

    Safety systems upgraded and commissioned under supervised execution.

  4. 04

    Evidence pack

    Compliance checklists and inspection registers issued for ongoing statutory reporting.

Outcomes

  • Hoisting availability restored to plan
  • Fully compliant signalling installation
  • Auditable inspection register handed to the operation

    A regulator flagged conveyor fire hazards across a coal handling plant. We built the risk matrix, the preventive regime and the standards uplift that closed it.
