Low-loading trailers, 2-10 axles
ST SERIES – LOW-LOADING
CREATED FOR GREAT THINGS
The ST-series is the most popular series of DEMARKO semi-trailers with the most versatile profile. The multitude of modifications and accessories offered by ST-series semi-trailers ensure their multi-functionality and efficiency in oversize transport. The modular design enables multiple length and width extensions. When the semi-trailer is extended, its functionality is ensured by for example an intermediate table that, depending on the dimensions, may be equipped with stanchion sockets, telescopic width extensions and even cavities for the wheels of construction machines.
Various variants of axle assembly support a series of configurations, enabling even hydraulic-assisted turns controlled by a wireless remote. The maximum technical load reaches 16 tonnes and the deck in traffic position may optionally be at the height of 800 mm. The height of the load deck may be additionally adjusted using special cavities for the wheels or buckets of the transported machines. Those cavities may be also filled with other transported loads.
INFINITE POSSIBILITIES
With all the modifications available, ST-series semi-trailers may exceptionally fulfil certain functions of platform or low-deck semi-trailers. Those possibilities are provided by for example the installation of a load trestle, which aligns the level of the load deck with the balcony, thus enabling the transport of long loads, such as pipes.
On another hand, with cavities for wheels it is possible to lower slightly the maximum load height and transport higher machines under bridges or high-voltage overhead lines. For the transport of less extreme loads, this is the optimum solution. DEMARKO low-loading semi-trailers are not only the answer for the needs of transport companies in general, but also facilitate the work of drivers and logistics specialists so that the whole industry could use the amenities we offer.
The 3-axle light semi-trailer is an exceptional product in this series. Its basic feature is its low unloaded weight of approx. 7,950 kilograms, which contributes to for example reduced fuel consumption in relation to heavier trailers and increased capacity of up to 40 tonnes. It is also the only low-loading semi-trailer that features cavities for construction machines and a cavity for an excavator bucket already in the standard version.
