Product description

Galbiati Group realizes large size components for Tunnel Boring Machines such as: Segment Erectors, planetary gearboxes and Cutterhead Supports.

ERECTOR FOR TBM
We have recently realized one 4.5 ton- segment erector for a TBM (Tunnel Boring Machine), rotating head, for an important excavation project of the Mumbai metro line 3, India.

The segment erector is made up of a fixed structure and a moving one, both made of electro-welded structural metalwork and machined on machine tools. The fixed part consists of two longitudinal beams on which the sliding guides of wear-resistant material are mounted. The moving part consists of the translating/rotating ring and the pick-up system.

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

Swinging = ± 5°
Pitch = ± 5°
Roll = ± 5°
Erector technical data:

Total beams length = 5,900 mm
Overall rotation = ± 220°
Translation movement speed = N/A
Rotational speed = max. 2 rpm
Maximum load = 4,500 Kg
Weight = 27,000 kg
Intrados diameter = 5,400 mm

CUTTERHEAD SUPPORTS

We have recently developed one Cutterhead Support for the cutter head of a TBM designed for an excavation project in Albania.
Some technical data of the Cutterhead support: a bearing support 4.2 metres wide with a roller bearing 3.2 metres in diameter, 10 planetary gears with a transmitted power of 210 kW each, and a lubrication system. Gross weight: 60 tons.

PLANETARY GEARBOXES

«TBM» (Tunnel boring machine) rotating head planetary drives for the construction of highways, railroads, subways, and hydro-electrics forced conduit tunnels.

They are sized for 100 kNm nominal torque, worthily designed and manufactured for heavy-duty applications, and equipped with water-oil cooling chamber. TBM head driving pinions, module 22 mm.
