Smart Pull Conveyor Pull Wire Switch
Engineered as part of the Smart Series conveyor safety range, Smart Pull devices provide reliable, compliant, and highly durable pull wire emergency stop solutions for demanding industrial environments.
Developed from decades of hands-on experience in mining and materials handling, the Smart Pull range delivers precise tripping performance, intuitive installation, and long-term resilience in both atmospheric and marine conditions.
Whether used for balanced pull-and-slack systems or directional pull trip applications, Smart Pull ensures your conveyor shutdown system meets the strict requirements of AS/NZS 4024 while maintaining the rugged reliability expected in Australian industry.
Engineered for Reliable Safety
Conveyor safety systems must operate reliably under all conditions, including power loss, cable damage, and device failure.
Smart Series is designed around fail-safe principles to ensure that any detected fault, communication loss, or device activation triggers a safe and controlled response.
Key fail-safe features include:
-
Normally closed safety circuits for emergency stop devices
-
Continuous line monitoring to detect open circuits or cable faults
-
Positive shutdown confirmation
-
Clear diagnostic feedback to maintenance teams
When integrated into a correctly designed safety circuit, Smart Series helps reduce downtime and risk while supporting compliance with mining safety requirements.

Get In Touch Pull & Slack Trip Type
Balanced, spring-tensioned protection for up to 200 metres.
The Smart Pull Pull & Slack Trip series provides a fully balanced emergency stop system using single-trip shafts with tensioning springs on both ends of the wire rope. This ensures consistent, reliable tripping even in high-vibration or temperature-affected environments.
Available in marine-grade LM6 aluminium (BK400PS) or UV-resistant Glass Reinforced Nylon (BK500PS), both housings offer exceptional corrosion resistance for long-term operation in atmospheric or marine conditions.
Key Features
-
Temperature & vibration compensation for stable performance.
-
IP66/67 heavy-duty environmental protection.
-
SIL2 certified (IEC 61508)—suitable for safety-related applications.
-
Spacious internal compartment (225 × 170 × 50 mm) for simplified termination and optional electronics—no external junction box required.
-
Encapsulated IP67 switches to prevent dust, moisture and rust ingress.
-
Visual compliance indicator confirming correct tensioning to AS/NZS 4024.3610.
-
Balanced lens indicator for fast visual alignment checks.
Standards
-
Complies with AS/NZS 4024.3610:2015 & BS EN ISO 13850:2008
Pull Trip Type
Independent dual-shaft protection for conveyor shutdown on pull or break.
The Smart Pull Pull Trip series features dual, fully independent trip shafts designed to activate when the cable is pulled from either direction. Built for straightforward installation between pull keys, this system provides a robust, easy-maintained conveyor shutdown method.
As with the PS series, the BK400P (aluminium) and BK500P (nylon) offer long-lasting, corrosion-resistant construction tailored for heavy-duty, and mining environments.
Key Features

SIL2 vs SIL3 – What’s Required?
| SIL2 | SIL3 | |
| Risk Reduction
| 100–1,000 | 1,000–10,000 |
| Typical Use
| Conveyor emergency stops | High-hazard process shutdown systems |
| Complexity | Practical and efficient | High redundancy required |
For most conveyor systems, SIL2 provides the appropriate level of protection. SIL3 is generally reserved for higher-consequence process industries.
