Internal width and center of gravity
Among the current offers on the market, the Gr.S22-SB-SS superstructure showcases the largest internal body width equal to 2,450 mm and the lowest-set center of gravity. Hardox450 steel body
This is a wear-resistant and shockproof steel capable of increasing the body service life and preventing premature wear caused by abrasive materials. The steel is supplied directly from Sweden. Origin of the material is confirmed by the “Hardox In My Body” certificate Increased strength
The body sides are made as seamless bent parts. This way, the number of welds in the body – potential places of stress points and corrosion pits – is reduced and the structure rigidity is improved for operations under high loads Extended capabilities
For the base of 1,990 + 2,960 + 1,450 mm, the internal dimensions of the Gr.S22-SB-SS superstructure allow transportation of concrete road slabs up to 6 m in length -
Automatic locking mechanism of the rear side
Ensures maximum unloading precision. The rear side is opened even at two degrees of body tipping. Internal width and low-set center of gravity
The Box-type superstructure design created by Grunwald engineers has an advantage over our competitors, as our design boasts the largest internal body width of 2450 mm and a lower centre of gravity. Hardox450 steel body
This is a wear-resistant and shockproof steel capable of increasing the body service life and maintaining marketable appearance over a long period. -
Half-pipe body
Semi-circular body structure helps to accelerate bulk cargo unloading. This type of a tipper body offers greater resistance to bents and deformations. Non-box bodybuilding is considered to be a prospective development of construction transportation. Variability depending on tasks
The design of the tipper superstructure was thought out to allow for production of bodies that combine various high-tensile and wear-resistant steels depending on appropriate transport task. The thickness is determined by a specific material and may vary from 5 to 6 mm in wall sides, and from 6 to 8 mm in the base of the body. Efficient unloading
Automatic tailgate locking mechanism ensures maximum unloading precision. The rear wall opens at two degrees of body lift. -
