We have recently realized one 4 ton- segment erector for a TBM (Tunnel Boring Machine) designed for an excavation project outside Mae Ngat, Thailandia.

The Tunnel Boring machine, for which the segment erector is intended, shall have a cutterhead of 4.9 m in diameter and will be used to excavate an hydraulic tunnel on site.

The erector comprises a rotating structure controlled by two planetary gears with sprocket drives and a crown wheel. The structure is supported by six rollers and moves on chromium-plated tubular guides.

The erector is equipped with a mechanical pick-up unit in order to grasp segments.(pick-up two pins). The mechanical pick-up unit grasps and retains segments for the entire duration of the positioning operations with three independent movements:

  • Swinging = 6°
  • Pitch = 6°
  • Roll = 6°

Erector technical data:

  • Longitudinal stroke= 1,800 mm
  • Overall rotation = ± 200°
  • Rotational speed = 2 rpm/minute
  • Maximum load  = 4 ton
  • Weight = 19,000 Kg
  • Intrados diameter  = 4,200 mm

Galbiati Group has recently realized one 3.5 ton- segment erector for a TBM (Tunnel Boring Machine) designed for an excavation project outside Shanxi, China.

The erector comprises a rotating structure controlled by two planetary gears with sprocket drives and a crown wheel. The structure is supported by six rollers and moves on chromium-plated tubular guides.

Below photo of the TBM segment erector set up entirely in the assembly area of Galbiati’s workshop.
