The CoverMaster is a modular curtainsider sliding cover that combines efficiency, safety, and durability in one system. Mechanical coil spring systems and innovative folding elements enable easy, temperature-independent opening and closing with minimal effort, while corrosion-resistant surfaces and XL certification ensure lasting reliability.

In combination with the MultiMaster roof rails, CargoMaster load securing system, and aerodynamic FlowMaster end beam, your trailer becomes a perfectly coordinated overall system – from faster loading and unloading to greater safety and lower fuel consumption.

Our Folding Wire Joints elements impress with their exceptional durability and robustness. Should an element ever need to be replaced, it can be done in a matter of seconds.

The precisely calibrated springs perfectly balance the weight of the roof tarpaulin and ensure that opening and closing operations remain smooth and easy. Thanks to a range of different lengths, our systems can be individually adapted to your requirements and the desired roof length – for maximum flexibility in every application.

The Multimaster aluminum profiles are designed for lightweight construction and maximum functionality. In addition to the roof system, they enable plug-and-play installation of ERMAX® Eternal LED strips – for reliable and uniform interior lighting that improves visibility and safety in the cargo area.

The MultiMaster 162.5 mm impresses with its particularly low installation height and has been specially developed for form-fitting load securing. The MultiMaster 105 mm is considered a versatile all-rounder, optimally matched to our CARGOMASTER load securing system, enabling flexible lashing of the load – safely, easily, and quickly.

Our Rear Carriage redefines efficiency and reliability in sliding tarpaulin roofs by consistently avoiding components that are prone to failure. Instead of a classic steel cable, this system uses an innovative locking bolt that allows the roof to be unlocked by simply sliding it open, thus eliminating typical sources of wear. The entire mechanism is designed to remain unaffected by temperature, allowing users to benefit from absolutely consistent operating forces at all times.

The integrated spring system, which comprises three different tension springs, ensures customized handling. The tension springs can be individually combined to enable ideal operating comfort when folding the end beam for a wide range of dead weights. Thanks to this robust design, the end carriage is not only extremely durable, but also completely maintenance-free. HESTAL underlines this quality promise with a lifetime warranty that guarantees you maximum reliability throughout the entire service life of the vehicle.
