LOAD RESTRAINTS9 Why is load restraint important? Every year Australians are injured and killed in crashes caused by unrestrained loads. This occurs when: Heavy objects fall from vehicles on to other vehicles or pedestrians. Drivers swerve to avoid falling or fallen items from vehicles. Spillage on roads from lost loads causes vehicles to skid and lose control. Unrestrained loads crash into vehicle cabins during emergency braking. Vehicles overturn because of loads shifting while cornering.

LOAD RESTRAINTS12 Why loads fall from vehicles: Everyday driving manoeuvres can involve heavy braking or cornering forces. Without sufficient restraint to counteract these forces, loads can fall from vehicles or shift causing loss of steering control.
LOAD RESTRAINTS13 Load placement and restraint requirements? The National Road Transport Reform (Mass and Loading) Regulations 1995 require that: A load on a vehicle must not be placed in a way that makes the vehicle unstable or unsafe. A load on a vehicle must be secured so that it is unlikely to fall or be dislodged from the vehicle. An appropriate method must be used to restrain the load on a vehicle. Comparable requirements apply in all States and Territories and you are advised to check the relevant legislation.
LOAD RESTRAINTS15 Tie-down Method Tie-down restraint is the most common form of load restraint and involves the use of lashings. The load is prevented from moving by friction between the load and the vehicle. The friction force prevents the load moving forward, rearward and sideways. The lashings are tensioned to clamp the load to the vehicle and to prevent the load from moving upwards. The friction force comes from both the weight of the load and the clamping force of the lashings. When the surfaces are slippery, the friction forces can be very low. Lashings that clamp the load onto the vehicle are called ‘tie-down lashings’ Friction cannot be taken into account unless the tensioned lashings provide adequate clamping of the load on the deck. Unrestrained loads, even on high friction surfaces, can bounce when travelling over uneven road surfaces and then shift during changes in speed, direction or slope.
LOAD RESTRAINTS24 Side Curtains Side curtains on vehicles are generally used to protect the load from rain and dust and are usually quicker, easier and safer than a tarpaulin to put in place and secure. Tarpaulins The main function of a tarpaulin is for weather protection. Tie Rails Many tie rails are not strong enough for use with chain and webbing without bending. The forces obtained with this equipment can exceed the strength of the rails particularly when using direct restraint lashings. Lashings Synthetic ropes, webbing, and high-tensile steel chains are the most commonly used lashings. Steel strapping and wire rope have some limited applications. Ropes have low strength and cannot be tensioned sufficiently to restrain heavy loads. Ropes Rope designed for use in transport (Transport Fibre Rope) is made from synthetic fibre. Rope made from natural fibre has lower strength than synthetic rope. Ropes should only be used for restraining relatively lightweight loads. Webbing Webbing assemblies comprise webbing, end fittings and tensioners. Tensioners can be either attached to the vehicle (truck winch) or ‘in-line’ (hand ratchet). Chain Chains are usually fitted with hooks on each end and tensioned with ‘over-centre’ lever tensioners, commonly called ‘dogs and chains’. The chain commonly used is 8 mm high tensile ‘transport’ chain with a typical lashing capacity of 3800 to 4000 kg. Other sizes are 6, 7.3, 10, 13 and 16 mm. All transport chain is marked at least every 500 mm with its lashing capacity (LC). Strapping Strapping can be steel or plastic material and is used for unitising loads into packs or bundles. Strapping can be highly pre-tensioned using manual or powered tensioners, making it very suitable as a tie-down lashing for heavy objects especially on container flats and pallets. Stretch and Shrink Wrapping Stretch film wrapping and shrink wrapping can be used to unitise a load consisting of many small objects such as palletised loads. They are often not suitable for heavier loads or loads with sharp corners that can penetrate the wrapping. The use of handling equipment can damage the wrapping and reduce its effectiveness. Wire Rope Wire rope is used to tie down loads that are placed cross-wise on the deck. The rope is tensioned with a winch or turnbuckle. Elastic Straps Elastic straps (octopus straps) are low strength lashings fitted with end hooks, commonly used for restraining lightweight equipment.
LOAD RESTRAINTS30 This shows some aluminium ingot packs that have tipped forwards under heavy braking. Note that the webbing tie- down straps have stretched and allowed the load to tip over. The unbraced front load rack was too weak to support the front pack.

LOAD RESTRAINTS33 Bulk bags must be restrained. Tie- down is seldom effective because the contents can settle during a journey and allow the lashings to loosen. Containing the bags on the vehicle with properly designed sides or gates is a better option.

LOAD RESTRAINTS47 1 The red items are lugs and fittings for direct restraint. They are bolted or welded to the load and the carrying vehicle. Some are designed to weld on a flat surface and others on a 90 degree edge or corner. 2 The pink items are chain gauges. They are used to determine if a chain is stretched or worn. They measure the link length, diameter and internal width. They are normally brand specific. Check with the manufacturer of the chain you use. 3 The black items are rubber snubbing blocks. They act as shock absorbers for chains to stop them breaking under impact loads. They usually consist of a circle of six chain links set in rubber. Half a link protrudes from each end to connect the rest of the chain.
