AS 4024 Palletiser Safety Upgrades
AS 4024 Palletiser Safety Upgrades
AS 4024–compliant safety upgrades for palletisers, including risk assessments, emergency stops, interlocks and safety PLC retrofits.
AS 4024 Compliant Palletiser Safety Upgrades
Palletisers often evolve faster than their original safety design—line speeds increase, robotic pick-and-place is added, control logic is modified, and guarding is adjusted to keep production moving. Over time, these changes shift the risk profile beyond what the original machine safety assumptions allowed.
AS/NZS 4024:2019 (AS 4024) compliant palletiser safety upgrades focus on realigning the machine’s current mechanical motion, control system behaviour, and access requirements with applicable Australian standards—without forcing full system replacement.
Common Safety Risks In Palletisers
Palletisers combine large moving masses, vertical motion, and automated material handling, often within shared production areas. Risk increases where palletisers interface with conveyors, stretch wrappers, or robotic cells.
Common risks identified during machine safety risk assessments include:
- Inadequate guarding around pallet build zones, sweep areas, and discharge points
- Emergency stop functions that do not reliably stop all hazardous motion across the cell
- Insufficient safety distances where operators access pallets or clear faults
- Manual intervention inside guarded areas during production or fault recovery
- Control system dependencies that delay stopping behaviour across integrated equipment
- Inconsistent safety requirements and stop behaviour across conveyors, palletisers, and adjacent plant
These issues are common in palletisers that have been extended, relocated, or upgraded without structured reassessment.
Why Old Palletisers Often Fail AS 4024 Compliance
Many palletisers in Australian plants were installed under earlier machinery safety expectations or imported without full alignment to local requirements. Subsequent upgrades often focus on throughput and line integration rather than safety function design.
Typical compliance gaps include:
- Guarding layouts that no longer meet current safety distance requirements
- Emergency stop circuits limited to individual zones rather than coordinated cell-wide safety functions
- Safety functions implemented within standard PLC logic rather than a safety-rated architecture
- Electrical modifications not reviewed against applicable electrical safety requirements (e.g. AS/NZS 3000 and IEC 60204-1)
- Lack of documented risk reduction, verification, and validation following automation changes
As palletisers become part of larger automated systems, these shortcomings become more visible during audits, incidents, or commissioning reviews.
Typical Safety Upgrades For Palletisers
Palletiser safety upgrades are typically retrofit-based, preserving mechanical frames and material handling hardware while upgrading guarding and safety-related control architecture.

Our Approach To Palletiser Safety Retrofits
Palletiser safety retrofits are developed following structured machine safety risk assessments aligned with AS 4024 requirements. Assessments consider pallet flow, operator access, fault recovery, and interaction with upstream and downstream equipment.
Retrofit designs are developed using existing engineering drawings where available and updated to reflect the as-installed condition and revised safety architecture. Installation is typically staged to maintain production continuity, with functional testing and validation performed prior to commissioning.
When To Upgrade Or Replace Palletisers
Safety upgrades are generally appropriate where the conveyor structure, drives, and mechanical components remain serviceable and compliance gaps can be addressed through guarding and control system improvements.
Replacement may be justified where:
- Mechanical wear prevents reliable stopping or guarding effectiveness
- Conveyor geometry cannot be modified to meet safety distance requirements
- Control system limitations prevent implementation of required safety functions
In many cases, targeted upgrades allow conveyors to remain production-ready while achieving compliance with current safety requirements.
