AS 4024 Roll Forming Machine Safety Upgrades
AS 4024 Roll Forming Machine Safety Upgrades
AS 4024–compliant safety upgrades for roll foaming machines, including risk assessments, emergency stops, interlocks and safety PLC retrofits.
AS 4024 Compliant Roll Forming Machine Safety Upgrades
In roll forming lines, safety weaknesses typically present as uncontrolled run-down, ambiguous stop states, or access during residual motion—rather than obvious faults during steady-state operation.
Roll forming machines operating in the Australian industrial environment are commonly retained as used machinery, supported through mechanical refurbishment, electrical upgrades, and incremental control changes rather than full replacement. Over time, changes to forming speed, servo control synchronisation, material profiles, and line configuration alter the original safety design assumptions. AS4024 compliance therefore depends on whether the current mechanical layout, electrical safety provisions, and control architecture continue to manage these changes in a predictable and verifiable manner.
AS4024-compliant roll forming machine safety upgrades focus on targeted retrofits to guarding, emergency stop circuits, safety relays, and safety-related control functions, allowing mechanically serviceable equipment to remain in operation while closing identified compliance gaps.
Common Safety Risks In Roll Forming Machines
Roll forming machines present well-defined potential hazards associated with driven roller banks, continuous nip points, material feed zones, trimming sections, and discharge conveyors. These risks are increased by high-inertia rotating components, synchronised control between multiple drives, and frequent manual intervention during setup or fault recovery.
Common risks identified during site assessments include:
- Inconsistent emergency stop coverage across infeed, forming, and discharge sections
- Exposed or partially protected roller nip points requiring frequent access
- Guards without monitored safety interlocks, permitting access while rollers remain energised
- Residual motion following stop commands due to drive inertia
- Control dependencies that result in unclear or delayed stop behaviour
These issues are frequently observed on forming lines that have been extended or modified without reassessment of safety functions.
Why Old Roll Forming Machines Often Fail AS 4024 Compliance
Many roll forming machines currently in service were designed to earlier safety expectations or supplied under frameworks that do not align with current interpretations of AS 4024 – Safety of Machinery.
Typical compliance shortfalls include:
- Emergency stop functions implemented through standard control logic rather than circuits supported by safety relays
- Guarding arrangements that do not meet current access prevention or monitoring requirements
- Undefined stopping performance for roller banks and servo-driven sections
- Electrical upgrades implemented without reassessment of electrical safety under fault conditions
- Incoming protection that does not adequately isolate faults upstream of the control system, including incorrectly specified Main Molded Case Circuit Breaker (MCCB) arrangements
As machines evolve operationally, these gaps often surface during audits, incidents, or investigations initiated from the maintenance workshop.
Typical Safety Upgrades For Roll Forming Machines
Safety upgrades for filling machines are generally structured to improve functional safety while preserving mechanically sound equipment. Retrofit strategies focus on updating Safety systems design without disrupting core Process Engineering or production throughput.
Ready To Review Your AS 4024 Safety Compliance?
Our Approach To Roll Forming Machine Safety Retrofits
Roll forming machine safety upgrades begin with a structured risk assessment aligned with AS 4024 – Safety of Machinery. The assessment considers current machine configuration, access requirements, stopping performance, and interaction between mechanical motion and control logic.
Retrofit solutions are developed to integrate with existing electrical and control architectures, minimise downtime, and align with established maintenance practices. Functional testing and verification are used to confirm that safety functions perform as intended prior to commissioning.
When To Upgrade Or Replace Roll Forming Machinery
Safety upgrades are generally appropriate where the mechanical condition of the filling machine remains sound and compliance gaps can be addressed through guarding and control changes. Replacement may be considered where:
- Required safety upgrades impose unacceptable constraints on production
- Mechanical wear compromises reliable stopping or guarding effectiveness
- Compliance gaps cannot be closed without fundamental redesign
In many Australian facilities, targeted filling machine safety upgrades extend equipment life while maintaining compliance with AS4024.
Related Safety Upgrade Solutions
Roll Forming machine safety upgrades are commonly delivered as part of broader compliance and maintenance programs, including:
