Refere-se a uma estado (ou estágio) do sistema hidráulico (pelo que pude compreender). Segue fragmento:

Introduction of Hydraulic System:

Two sets of separate and closed type system ares used:

HPV55-02 series closed type variable displacement plunger pump and HMV75-02 variable displacement plunger hydraulic motor are used.

The system has good reliability, good resistance to big loads, good stability, good accuracy, good adaptability, lower shock, ***zero loss on nonloading***, lesss heating at working .The paver can stop and brake when the swashplate of the pump is at Neutral position so that the straight driving and speed differential steering can be realized quickly when the paver is at working state, also spot turn can be realized at operation stat.
