    AI Overview
    Main Beam - Robbins
    Open-type gripper TBMs (main beam TBMs) are designed for fast, efficient excavation in stable hard rock, utilizing lateral gripper shoes to anchor against tunnel walls while pushing the cutter head forward. Leading manufacturers include Herrenknecht, Robbins, Terratec, CRCHI, and NHI. 
    Key Manufacturers and Features 
    • Herrenknecht AG: Provides highly customizable gripper TBMs (2 to >12m diameters) for hard rock, featuring water jets for dust suppression, roof drills, and high-speed boring capabilities.
    • The Robbins Company: A major manufacturer specializing in hard rock main beam TBMs, offering machines with advanced probe drills and back-loading cutters.
    • CRCHI (China Railway Construction Heavy Industry): Produces open-type gripper TBMs for hard rock projects like, water conservancy, and rail tunnels, focusing on high wear resistance.
    • TERRATEC: Provides hard rock TBMs designed for diverse, abrasive geological conditions.
    • NHI (Northern Heavy Industries): Produces Open-Type Gripper TBMs designed for Class II to V hard rock with high thrust capabilities.
    • Kawasaki Heavy Industries: Produces TBMs with a simple, robust design (cutter head, beam, gripper) suitable for efficient hard rock tunneling. 
    Key Characteristics of Open-Type Gripper TBMs 
    • Ground Suitability: Ideal for stable to highly fractured hard rock; not for soft ground.
    • Advance Rate: Capable of exceeding 1,000 meters per month in ideal conditions.
    • Method: Uses hydraulic gripper shoes to lock into the tunnel walls, allowing the cutterhead to push forward without a shield.
    • Support System: Typically installs roof bolts, steel ribs, or shotcrete directly behind the cutterhead for immediate ground support. 
    Main Beam TBMs are often chosen for long, hard rock tunnels to minimize costs and maximize speed.
