Transporting heavy machinery, such as excavators or bulldozers, represents one of the most complex logistical challenges. Faulty anchoring can lead not only to cargo damage but also to serious accidents on public roads.
In this article, we will analyze the essential techniques for securing high-tonnage loads, focusing on the correct selection and application of lashing straps.
1. Evaluating Anchor Points
The first, and most critical, step is identifying robust points on the machinery. These are specially designed for lashing (e.g., integrated eyes or hooks). Never use weak structural parts or decorative components.
2. Calculating Tension Force
Each strap has a Standard Tension Capacity (LC) and a Equipment Capacity (STF). For a 20-ton machine, it is necessary to calculate the force generated by acceleration, braking, and vibrations. A rule of thumb is to use at least 4 straps with an individual capacity exceeding the distributed weight by 50%.
3. Geometry and Lashing Angle
The angle between the strap and the platform is crucial. An angle that is too wide drastically reduces the effective holding capacity. Straps should be stretched as parallel as possible to the platform, and the locking systems (metal ratchet) must be visually checked for complete engagement.
Implementing these techniques, along with the use of high-strength polyester straps, ensures that the cargo remains stable for the entire duration of the journey, protecting both the investment and traffic participants.
