How many straps are needed on a semi-trailer to secure the load properly? This is a key question for safe transport that every professional driver needs to know. The right number and method of securing straps guarantees the protection of transported goods and minimises the risk of road accidents, in accordance with applicable regulations. Proper load securing is the foundation of professional transport.

Securing loads for road transport – basic principles
Securing loads in road transport requires not only the right equipment, but also technical knowledge. Transporting goods without proper securing can lead to serious consequences – from damage to the goods being transported, through to damage to the vehicle, and even causing an accident. Before you start securing the load, remember to:
- check the technical condition of the straps (no abrasions, cuts, functioning tensioning mechanisms),
- select the appropriate straps for the type and weight of the load,
- plan the distribution of the load on the trailer, taking into account the weight distribution.
It is important to know how to secure the load, because proper securing of goods is not only a matter of safety, but also a legal requirement, and failure to comply can result in heavy penalties.
How many straps should be used on a semi-trailer?
Drivers often ask how many lashing straps should be used on a trailer. There is no single, universal answer – the number of lanes depends on several factors, including:
- the type and weight of the load,
- the dimensions of the items being transported,
- the specific characteristics of the vehicle,
- the distance and transport conditions.
According to EN 12195-1, each transport strap has a specific lashing capacity (LC – Lashing Capacity). For a standard 50 mm wide strap, it is approximately 2500 daN (2.5 tonnes). To correctly determine how many straps you need on a semi-trailer, you need to calculate the forces acting on the load during transport . For example, for a load weighing 1000 kg, with a friction coefficient of μ=0.3 (wooden pallet on a wooden floor), you need a minimum of 2 straps to secure the load against forward movement (when braking) and one strap each for sideways and rearward movement.
Securing goods – techniques for correct strap tensioning
Effective securing of loads in road transport requires knowledge of the appropriate fastening techniques. The most popular methods are:
- diagonal fastening – the straps are fitted diagonally across the load, preventing movement in all directions;
- top-down lashing (from top to bottom) – the strap passes over the top of the load and presses it down onto the ground;
- loop lashing – the strap wraps around the load, forming a closed loop;
- spring lashing – used for flexible loads.
Remember to tension the straps evenly and check their tension regularly during transport, especially after the first few kilometres of driving, when the load may settle slightly.
How to secure a load – legal requirements and maintenance of lashing straps
How to secure a load with straps in accordance with the law? The European Union applies the EN 12195 standard, which sets out methods for calculating fastening forces and requirements for fasteners. Directive 2014/47/EU requires load securing to be checked during roadside technical inspections. In Poland, these issues are regulated by the Road Traffic Act and the Regulation of the Minister of Infrastructure on the technical conditions of vehicles. Incorrect securing of goods is punishable by fines ranging from PLN 200 to as much as PLN 2,000. Proper securing of goods also depends on the technical condition of the straps used. . To extend their service life:
- store the straps in a dry place, away from direct sunlight;
- clean them regularly with mild detergents;
- check them for mechanical damage before each use;
- replace straps that show any signs of wear and tear.
Knowing how to secure cargo with straps is essential for every professional driver. Securing cargo in road transport is a key competence for safety, protection of transported goods and avoidance of penalties. Remember that the right number of straps on the trailer and their correct use can save lives and property on the road . Regularly update your knowledge of securing methods and comply with applicable regulations.
