Note:

This unit doesn` t require precise installment on the well head. It is equipped with high pressure hydraulic hoses, length 35 m, wrapped on three drums, for BOP equipment operation, enabling operations on pony substructure (with own hoist), as well as on higher substructure (with other hoist of higher capacity). BOP equipment and complete injector during operations can be hanged on tracelling block. In this manner drilling operations can be performed on the biggest rigs. This equipment was not design to work on extreme cold temperature.

  • Height: 4,15 m
  • Vehicle saddle height: 1,55 m
  • Weight: 52,60 t
  • Number of shafts: 6
  • Highest shaft pressure: 9,30 t
