Product Profile of Main Beam Tunnel Boring Machine

Industrial Main Tunnel Boring Beam Machine is a complex design that comes with a cutter head with disc cutters ranging from 11inches to 20inches in diameter which are positioned for optimal boring of the given rock type. The Tunnel Boring Machine has the cutter heads which match with different geologic conditions to ensure smooth and efficient boring. The Tunnel Boring Machine comes with a hydraulically actuated side and roof support that stabilizes the cutter head by minimizing cutter wear. Main Beam Tunnel Boring Machine has large-diameter high-load capacity disc cutters to penetrate the rock efficiently.

Key Features of Main Beam Tunnel Boring Machine

• A custom-designed rotating cutter head matched to the geologic conditions to ensure smooth, efficient boring
• Large-diameter high-load capacity disc cutters to penetrate the rock efficiently
• A large-diameter main bearing and bull gear assembly specially designed for high-thrust applications in underground conditions
• Robbins’ unique floating gripper system for continuous steering capability
• Hydraulically actuated side and roof supports to stabilize the cutter head by minimizing cutter wear
• Laser target steering for tunnel accuracy
• Steel dust shield to maintain a seal between the tunnel and the cutter head, trapping dust in the cutter head for removal by scrubber through the main beam
• Efficient belt conveyor inside the main beam transfers muck from the cutter head to the rear
• Equipped with automated precision guidance system and close circuit television facility
• Variable cutter speed with data acquisition system
• Designed with automatic fire suppression system and closed loop cooling system for conservation of water
