Body heating system

Branch pipes and corrugated pipe of the body heating system are made of АISI 304 stainless steel. Increased high temperature and operating pressure range characteristic of АISI 304 steel ensures the maximum service life for these elements.

Hydraulic system

Hydraulic equipment reliable enough for operations under high loads is supplied directly from the leading European suppliers. High opening speed ensures fast unloading of the body.

Seamless bent side parts

The body sides are made as a seamless bent part. The total number of welds in the body – potential places of stress points and corrosion pits – is reduced. Strength and rigidity are improved for operations under high loads. The body weighs less than standard bodies with stiffening ribs.
