Whatever the next load brings. The value of a trailer is not only measured by what it carries today. It is also measured by what it enables you to carry tomorrow. Biostar moves flexibly between agricultural bulk products and a wide variety of other loads. Its extensive configuration possibilities allow it to support changing seasons, different customers and valuable return-load opportunities. That means greater freedom when planning transport and more possibilities to keep every journey productive.

Versatility starts beneath the load Every product behaves differently. Some flow easily. Others are abrasive, moist, heavy or sensitive. That is why the right moving floor is essential. Biostar can be equipped with different floor profiles, functional options and protection solutions to create the right balance between payload, durability and application range.

STAS Biostar | 7 Premium components only
Premium components only The complete trailer is only as reliable as the parts it is built with. That is why Biostar is developed with premium components and branded parts chosen for dependable performance and strong spare-parts availability. That choice supports easier maintenance, better serviceability and less unnecessary downtime over the lifetime of the trailer. Parts help get the trailer back into operation faster. That is how you protect uptime. Not only by building strong, but also by making sure the trailer stays practical throughout its working life.

Save your driver The safest solutions are often the ones that make the correct way of working feel natural. Anti-slip surfaces provide secure footing. Practical ladders and handholds support safe access. Centralised and remote controls help the driver operate essential functions from a suitable position. Stable handling inspires confidence on the road.
The safest catwalk in the world. Ecostar is equipped with a safe catwalk with anti-slip surface, practical trapdoors and a high guard rail. Standard fall protection adds another level of safety during work on top of the catwalk. The rear ladder is designed with anti-slip steps and an integrated grip in the door hinge area, helping the driver access the trailer with more confidence. These are details that matter in real life: better grip, better access and a safer working environment on and around the trailer.

Dawbarn hydraulic roof system. A reliable sheeting system is essential in daily bulk transport. Biostar features a Dawbarn sheeting system designed for practical, dependable use and easy repairs with good spare parts availability. Combined with the trailer’s strong body construction, it helps protect the load space and supports efficient operation in a wide range of transport conditions.

Strong lifetime value A trailer designed for different loads needs a foundation that can handle different forces. Biostar combines a fully welded, self-supporting aluminium body with a strong chassis and frame construction. Wide sidewall panels, high cross-members and a reinforced head section work together to distribute the forces created by loading, driving, turning and unloading. The result is strength you can experience on the road: stable handling, predictable behaviour and a construction developed for years of intensive work.
140 mm high frame crossmembers over the entire length The higher the traverses, the better the frame resists forces from the load as well as torsional forces during driving.
Reinforced kingpin crossmembers Crossmembers receiving the pulling force are reinforced to withstand torsion from the kingpin.
