When Loads Move, Problems Follow

Shifted cargo costs more than damaged goods. It creates rejected shipments, compliance failures, safety incidents, and operational delays that compound through distribution networks. Transport managers know the frustration of loads arriving askew despite appearing secure when they left.

We’ve spent years at Ferrier Industrial working alongside freight operators who move everything from steel coils to mixed palletised goods across Australia and New Zealand. The pattern is consistent: effective load restraint equipment needs to match actual cargo characteristics, vehicle configurations, and the practical constraints of loading crews working under time pressure.

What looks adequate on paper doesn’t always perform on highways, rail lines, or ship decks. Cornering forces, hard braking, road shocks, and weather exposure test restraint systems in ways that specification sheets can’t fully predict. The difference between a stable load and a shifted one often comes down to material selection, friction management, and how well components integrate with existing equipment.

Our approach focuses on restraint solutions that operators can deploy consistently—hardware that’s durable enough for high-cycle use, intuitive enough for crews with varied experience, and backed by local stock when replacements are needed.

The Operational Case for Proper Securement

Cargo travels through multiple hands and transport modes before reaching its destination. A shipment might start in a distribution centre, transfer to an intermodal container, move by rail or sea, then finish on a final-mile truck. Each handover introduces variables that affect load stability.

Australian Load Restraint Guide requirements and carrier SOPs establish baseline standards, but meeting those standards in practice requires hardware suited to real cargo dimensions, vehicle lashing configurations, and labour realities. Compliance matters, but so does repeatability—systems that are technically adequate but awkward to install won’t be used correctly every time.

Effective securement combines multiple elements working together. Friction between cargo and deck reduces the forces that blocking and strapping must resist. Physical barriers prevent sideways and longitudinal movement. Tensioned strops apply downward pressure that amplifies friction effects. Void-filling materials stop loads from shifting into empty spaces.

Each element plays a role, and weakness in one area increases demands on others. A load sitting on bare steel requires more strapping tension than one resting on high-friction rubber matting. Gaps left unfilled allow movement that straps alone may not prevent. Understanding these interactions helps procurement teams specify restraint equipment that addresses their actual risks rather than just ticking compliance boxes.

The cost of getting this wrong extends beyond damaged goods. Safety incidents during transport or unloading create liability exposure. Rejected shipments disrupt customer relationships. Time spent re-securing shifted loads eats into delivery windows. Investing in appropriate restraint hardware pays back through avoided problems rather than just meeting minimum requirements.

Restraint Solutions Across Different Applications

At Ferrier Industrial, we supply cargo restraint equipment spanning several categories that address different aspects of load stability. Our portfolio covers general freight operations, heavy industry applications, and intermodal transport—each with distinct requirements.

Friction materials form the foundation of many restraint systems. Our load-restraint rubber mats create high-friction interfaces between cargo and deck surfaces, reducing reliance on strapping alone. These work under pallets, block-stacked goods, or any load where increased grip improves stability.

Tensioned strapping handles the active restraint component. We supply ratchet strops and cargo straps in polyester webbing with weather-resistant hardware rated for repeated outdoor use. Custom assemblies with specific end fittings match different vehicle lashing configurations.

Dunnage serves multiple purposes—creating stable bases, filling voids, and protecting cargo surfaces. Our LVL high-friction dunnage uses eucalyptus-sourced laminated veneer lumber with vulcanised rubber lining, offering dimensional stability that solid timber can’t match across temperature and humidity changes. Dunnage airbags fill gaps in partially loaded containers and trailers, preventing lateral and longitudinal shifting.

For steel and heavy industry, we’ve developed engineered systems through long-standing partnerships with major producers. Bore vertical and horizontal coil restraint corners secure cylindrical loads across varying diameters without custom cradles. Truck cradles with vulcanised rubber bonded to steel frames provide vibration damping and positional stability. Chain protectors prevent wear on lashing chains while protecting cargo surfaces from marking.

Core categories in our restraint portfolio:

• High-friction rubber mats and LVL dunnage with vulcanised rubber lining for stable cargo bases and increased grip
• Ratchet strops and cargo straps in weather-resistant polyester with custom assembly options for different lashing configurations
• Dunnage airbags for void-filling in trucks, containers, and rail wagons
• Engineered coil and sheet restraint systems designed for steel industry transport requirements
• Chain protectors, truck cradles, and specialty blocking hardware for heavy loads

Friction, Blocking, and Tensioning Working Together

The Role of Friction in Load Stability

Friction is the first line of defence against cargo movement. When a truck brakes hard, inertia pushes the load forward. The friction between cargo base and deck surface resists this force. Higher friction means less reliance on straps and blocking to prevent shifting.

Bare steel decks offer limited natural friction, especially when wet or contaminated with dust. Rubber matting placed under loads increases the friction coefficient substantially, changing the equation for how much additional restraint is needed.

We supply rubber mats in standard footprints tested for friction performance suitable for palletised and block-stacked freight. For heavy loads, our LVL dunnage with seven-millimetre vulcanised rubber lining provides both a stable base and high-friction interface. The laminated veneer lumber maintains dimensional integrity under sustained load and repeated use, unlike solid timber that can compress or warp.

Material selection matters for different cargo types. Abrasive products may wear through softer compounds. Chemical exposure can degrade certain rubbers. Temperature extremes affect friction properties. Matching materials to operating conditions ensures friction performance holds up over time.

Blocking and Bracing Techniques

Blocking prevents movement by filling gaps and creating physical barriers. When cargo doesn’t span the full width or length of a trailer, empty space allows shifting under inertial forces. Rigid blocking or inflatable airbags wedged into voids eliminate this movement path.

Dunnage airbags suit many general freight applications. Inflated between cargo and walls, they apply outward pressure that holds loads in position. These work well for partial loads where cargo composition varies between shipments—no custom blocking required for each configuration.

Rigid blocking serves applications where airbag pressure isn’t appropriate or where loads require more precise positioning. Hardwood and LVL dunnage blocks fit against cargo edges to prevent sideways movement. For steel coils, engineered restraint corners provide blocking that accommodates different diameters within a universal system.

The blocking method needs to match cargo stability. Fragile goods may not tolerate point loads from rigid blocks. Heavy items may compress softer materials. Procurement teams should consider both the cargo being restrained and the forces involved when selecting blocking approaches.

Tensioned Strapping and Hardware

Straps apply downward force that increases friction between cargo and deck while also physically holding loads in position. Over-the-top strapping is standard for most freight, but effectiveness depends on anchor points, webbing strength, and tensioning hardware.

Ratchet mechanisms provide controlled tensioning that maintains consistent pressure. We supply strops with DOT-compliant hardware in various lengths, with custom assembly options for specific end fittings that match vehicle lashing rails.

Webbing material affects durability and handling. Polyester offers good strength-to-weight ratio and weather resistance. For applications involving abrasion or chemical exposure, appropriate grades prevent premature failure.

Strap placement matters as much as strap strength. Angles that are too steep reduce downward force effectiveness. Straps running over sharp cargo edges risk cutting. Adequate anchor points on the vehicle determine available lashing configurations. Understanding these factors helps specify transport restraint equipment that performs in practice.

Heavy Industry and Intermodal Considerations

Steel products and other heavy industrial loads create demands that general freight restraint can’t address. Multi-tonne coils generate substantial inertial forces during braking and cornering. Sheet packs with smooth surfaces offer minimal natural friction. Concentrated point loads stress deck surfaces and restraint hardware.

We’ve worked with steel producers for decades developing systems that handle these challenges. Our bore vertical coil restraint corners use cold-rolled steel plate with vulcanised rubber contact surfaces, engineered for the forces generated by heavy cylindrical loads. The design accommodates varying coil diameters, enabling mixed packing without specialised equipment for each size.

Truck cradles provide stable positioning for cylindrical loads during road transport. Vulcanised rubber bonded to steel frames creates vibration damping that protects both cargo and vehicle. Our cradles have demonstrated extended service life under demanding conditions, with minimal maintenance requirements.

Chain lashing remains common for heavy loads, but chains can damage both cargo surfaces and the chains themselves without proper protection. Our single-edge chain protectors use stainless steel pressing with vulcanised rubber to prevent wear and marking.

Intermodal transport introduces additional variables. Containers transfer between trucks, rail, and ships, experiencing different motion profiles at each stage. Ship transport adds roll and pitch that land modes don’t face. Restraint systems need to account for combined forces across the full journey.

Container liners convert standard intermodal containers into bulk vessels for granular materials, with restraint requirements focused on containing product during discharge operations. For palletised container freight, friction mats under each pallet reduce strapping demands while maintaining stability through multiple transport modes.

What Evaluators Typically Consider

Procurement teams assessing freight restraint equipment balance several factors that affect total cost-in-use and operational performance. Initial price matters, but durability under high-cycle use, compatibility with existing vehicles, and supply continuity often prove more significant over time.

Key evaluation criteria include:

• Material durability under repeated use, weather exposure, and contact with abrasive or corrosive cargo
• Friction coefficients and load ratings verified against applicable standards and carrier requirements
• Compatibility with existing vehicle configurations including deck materials and lashing point positions
• Installation simplicity that minimises training requirements and setup time per load
• Serviceability and access to replacement parts from local stock without extended lead times
• Customisation potential for non-standard cargo or unusual vehicle configurations
• Supply assurance through JIT delivery or consignment stock arrangements

Our Approach to Restraint Solutions

At Ferrier Industrial, we recognise that cargo securing isn’t one-size-fits-all. What works for palletised consumer goods won’t suit steel coils. Container specifications differ from flatbed requirements. Operator workflows and site constraints vary across organisations.

We begin with discovery. Our team reviews cargo profiles, transport modes, handling equipment, and the practical realities of loading operations. We measure lashing points, deck surfaces, and load dimensions. We identify where current restraint methods fall short or create inefficiencies.

Design and prototyping follow. Standard applications might involve selecting from existing product lines and confirming fit through sample testing. Complex requirements lead to custom solutions—modified dunnage dimensions, specific rubber compounds, tailored strap assemblies, or engineered restraint frames.

Our facilities in East Tāmaki and Unanderra support distribution across Australia and New Zealand, with manufacturing partnerships that enable both local customisation and volume production. We maintain stock on common load restraint equipment specifications and establish consignment arrangements for high-volume users who need parts available without large inventory investments.

Spares and ongoing support remain priorities throughout the equipment lifecycle. We keep technical records for custom solutions, enabling rapid remanufacture when components need replacement. For high-volume users, we establish review cycles to assess wear patterns and optimise replacement schedules before failures occur.

Practical Steps for Specifying Restraint Hardware

Selecting appropriate securement systems starts with clear understanding of what you’re restraining and how. Structured evaluation helps match hardware capabilities to operational realities.

Steps for effective specification:

• Document cargo characteristics including dimensions, weight ranges, surface materials, and handling requirements
• Map transport modes and transfer points, noting motion profiles and standards applicable at each stage
• Identify vehicle configurations including deck materials, lashing positions, and structural limitations
• Review current methods and gather data on failures, installation time, and operator feedback
• Determine reusability expectations and lifecycle considerations for high-cycle operations
• Clarify customisation needs versus standard solutions based on cargo variety
• Establish supply continuity requirements including response times and spares availability

Moving Forward with Better Restraint

Loads that arrive stable preserve product integrity, avoid claims, and maintain customer relationships. Restraint systems that operators deploy consistently create reliability across shifts and reduce safety incidents.

We’ve built long-term relationships with transport operators and shippers who need load restraint equipment that performs—cycle after cycle, load after load. Our solutions come from understanding what happens on loading docks and highways when schedules are tight and margins matter.

Whether you’re moving mixed palletised freight that needs friction mats and strapping, heavy industrial loads requiring engineered blocking systems, or bulk materials suited to container solutions, we can discuss options matched to your cargo profiles and constraints.

At Ferrier Industrial, we’re happy to share technical specifications, arrange sample evaluation, or conduct a site review to understand current methods and where improvements might help. No pressure—just practical guidance from a team that’s supplied restraint solutions throughout Australia and New Zealand for years.
