What is the Railics MLD?
Railics is a Rated Capacity Limiting Control System developed by Nijhuis Engineering, backed by over 40 years of field-proven design. It is purpose-built for use on rail-mounted equipment and ensures maximum safety and compliance for operators working in rail and construction environments.
The Railics MLD system includes:
• Rated Capacity Indicator (RCI): Alerts the operator when the machine is approaching its lifting limit, calibrated at installation.
• Rated Capacity Limiter (RCL): Automatically stops lifting or movement when the machine reaches its safe limit, protecting both the operator and the machine.
• Movement Limiting Device (MLD): Limits height, slew (rotation), and boom reach to prevent machines from breaching job site safety zones.
• Virtual Wall Feature: Prevents encroachment into restricted green zones using pre-programmed area limits.
• Real-Time Load Display: Shows exact weight being lifted on a high-visibility touchscreen.
• Integrated Data Logger: Provides black-box-style tracking for safety audits and compliance reporting.
• Fast Setup and Calibration: Completed in just a few days with modular prefab connection kits.
• Touchscreen Interface: Enables on-site configuration and override via manager key.
• Universal Compatibility: Works on all brands and sizes of machines.
Equipment That is Compatible with the Railics MLD:
• Road Rail Vehicles (RRVs)
• Excavators of all sizes
• Mobile Elevated Work Platforms (MEWPs)
• Hi-rail trucks with hydraulic lifting systems
• Zoom booms and loaders
The system is engineered to work across a wide range of attachments and dynamic load scenarios, and supports up to seven tools integrated into the load and movement calculation at once.
Why Are Movement Limiting Devices (MLDs) Critical for Rail Equipment in Canada?
In Canadian rail work zones, safety and precision are non-negotiable. Equipment operating near active tracks, power lines, or protected green zones must meet strict operational limits. Regulatory bodies like Metrolinx are now requiring certified Movement Limiting Devices (MLDs) to mitigate risk, improve accountability, and ensure site-wide safety compliance (Source).
Movement Limiting Devices help rail operators:
• Prevent hydraulic booms from entering restricted zones
• Avoid machine tip-over from excessive lifting
• Monitor real-time lifting loads with calibrated accuracy
• Meet current and future regulatory safety mandates
• Improve operator awareness and reduce errors
The Railics system fulfills all these functions in one easy-to-use platform.
How Does the Railics MLD Ensure Compliance
The Railics MLD meets multiple international and domestic standards for rail operation safety, including:
• Metrolinx Technical Standard – Adjacent Track Open Standard (ATO) (Source)
• European Standard 15746-2:2020 (Source)
• UK Rail Industry Standard RIS-1530-PLT (Source)
Whether you’re working on Metrolinx infrastructure, a municipal transit line, or a national rail corridor, the Railics system is a top-tier solution to meet equipment safety requirements across Canada.
What Are the Railics MLD Specifications?
Built for durability, precision, and compliance, the Railics system offers a comprehensive suite of features designed specifically for rail and construction environments.
Railics MLD Specifications:
• 7-inch touchscreen display
• Stainless steel angle sensors (IP69 rated)
• Multi-bank hydraulic cut-out valve for excavators
• Standard height, slew, and area limiting functions
• Fast prefab connection modules for installation in days
• Compatibility with rail and tire-mounted machines
• Custom programming options for jibs, clamps, forks, and more
• Operator feedback on lifted loads and job site limits in real time
• Integrated datalogging and audit-ready records
All of these features make the Railics system the most advanced and comprehensive MLD platform available in the market today.
What is the Difference Between Railics and Arealics?
For customers who do not require full-rated capacity limiting or weight monitoring, Arealics is a simpler, cost-effective alternative that includes MLD area limiting features only. It limits height, slew, and reach but does not include full RCI/RCL integration or weighing capability.
Best of all, Arealics can be upgraded to Railics at any time, allowing businesses to scale their safety compliance as their equipment usage or project demands change.
What Applications Can the Railics MLD Be Used For?
This system is the ideal safety solution for:
Rail contractors working under Metrolinx requirements
Ensure your fleet meets the latest movement-limiting system standards.
Equipment rental companies
Offer added value and peace of mind with MLD-equipped excavators and hi-rail trucks.
Infrastructure companies and utilities
Operate safely around live rails, overhead lines, or high-risk zones with automatic motion limiting and load management.
Construction companies and municipalities
Protect operators and job sites while maintaining full compliance with evolving safety regulations.
