Transporting heavy machinery, such as excavators or bulldozers, represents one of the most complex logistical challenges. Incorrect anchoring can lead to cargo shifting, with serious consequences for road safety.

In this article, we explore the fundamental principles and advanced techniques for properly securing this equipment.

Calculating Load Forces

The first, and most critical, step is calculating the forces acting on the cargo during transport. These include braking, acceleration, and turning forces. For a 20-ton machine, the restraining force required for securing can exceed 10 tons. High-strength polyester straps must be selected with a Load Capacity (LC) and a Minimum Breaking Load (MBL) that far exceed these values, applying a safety factor of at least 2:1.

The Anchoring Point System

It is not enough to tie the machine only to the corners of the platform. It is essential to create a securing network. This involves using a minimum of 4-6 straps, placed at opposing angles, forming an "X" pattern over the stable elements of the machine (frame, axles, dedicated points).

Primary straps: Secure the main mass of the machine.
Secondary (stability) straps: Prevent lateral sway and oscillations.
Motion limiters: Block the wheels or tracks.

The Importance of Surface Preparation and Uniform Tension

A common mistake is neglecting the contact between the strap and the machine. Sharp edges or rough surfaces can damage the webbing. Using corner protectors is mandatory. Also, all straps must be tensioned uniformly using the metal ratchet, to distribute the load equally. One strap that is too tight and one that is loose creates disproportionate stress points.

En-route Check:

The habit of stopping and checking strap tension after the first 20-30 km of travel is crucial. The initial settling of the cargo can cause a slight relaxation of the system.

Investing in quality straps and proper personnel training are not costs, but measures to protect assets and human life. Choosing a professional securing system, such as the one offered by TornadoStrap, ensures peace of mind throughout the transport.

In daily transport and logistics activities, the correct securing of cargo is paramount. We have gathered the most frequent questions received from our customers to provide you with clear and practical answers.

1. How do I choose the correct capacity (LC) of a strap?

The Lashing Capacity (LC) indicates the maximum force a strap can withstand under ideal conditions. To choose it correctly:

Calculate the total weight of the cargo that needs to be secured.
Apply a safety factor. It is recommended that the total LC of the straps used be at least 1.5 times the weight of the cargo.
Consider the lashing angle. If the straps are applied at an angle less than 90°, their effective capacity decreases.

For example, for a 10-ton load, you will need straps with a total LC of at least 15 tons.

2. What is the difference between polyester and nylon straps?

Both are popular, but have different characteristics:

Characteristic	Polyester (Our Product)	Nylon
Moisture resistance	Excellent – does not absorb water, maintains strength.	Low – absorbs moisture, which can reduce strength.
Elasticity	Minimal – provides rigid and stable securing.	High – stretches, which can loosen the securing.
UV and chemical resistance	Superior – ideal for long-distance outdoor transport.	Moderate.

For securing heavy loads and machinery, polyester straps are recommended due to their stability and durability.

3. How often should straps be inspected?

Regular inspection is essential for safety. We recommend:

Visual inspection before each use: Look for signs of wear, cuts, burns, undone stitches, or severe discoloration.
Detailed monthly inspection (or according to the company's schedule) for intensively used straps.
Immediate withdrawal from service of any strap showing defects. "Better safe than sorry" is the guiding principle.

4. Can damaged straps be repaired?

No, absolutely not. A lashing strap is a safety device. Any homemade or stitched repair cannot restore the initial structural strength and creates a critical point of weakness. A damaged strap must be replaced immediately with a new one, in accordance with standards.

5. How do I store straps correctly to extend their lifespan?

Correct storage prevents premature degradation:

Clean them of dust and dirt before storage.
Store them in a dry, cool, and well-ventilated place, away from direct sunlight.
Avoid direct contact with the ground, oils, acids, or aggressive solvents.
Do not throw straps or leave them tangled; coil or fold them neatly.
