Mobile Tunnel Gantry Work Platform

Custom Elevated Access for Tunnel Work

The SafeSmart Mobile Tunnel Gantry Work Platform is a custom access system for tunnel finishing, overhead service installation, inspection, and maintenance work. It creates an elevated work area where crews need practical access to the tunnel crown, walls, utilities, and installed infrastructure.

Each gantry is designed around the tunnel profile, available clearance, work activity, and site movement requirements. A wheeled base supports relocation along the tunnel, while adjustable stabilizing jacks can be specified to establish a stable working position once the platform is in place.

Unlike a temporary arrangement assembled around each work zone, a purpose-built mobile gantry can be configured as a repeatable access solution for progressing tunnel work. SafeSmart’s in-house team can develop the platform layout and access arrangement around the specific tunnel environment.

Key Features

• Custom-designed for tunnel finishing and overhead service work
• Elevated work platform configured around the tunnel profile
• Wheeled base for movement between tunnel work areas
• Adjustable stabilizing jacks for the working position
• Aluminum construction for a lighter alternative to conventional steel access structures
• Configurable access ladder and gated-entry arrangements
• Optional removable platform sections for site-specific access requirements
• CAD-based design development and fit review for the intended tunnel environment

Typical Applications

• Tunnel electrical, communications, and utility installation
• Overhead tunnel service work
• Road tunnel fit-out and finishing operations
• Rail tunnel construction and maintenance access
• Inspection of tunnel linings and installed infrastructure
• Repeatable access along progressing tunnel work zones

Specifications

• Product Type: Custom mobile tunnel gantry work platform
• Construction: Aluminum platform system
• Mobility: Wheeled configuration for movement along the tunnel
• Stabilization: Adjustable jacks, specified to suit the configuration
• Access: Ladder and entry arrangement configured for the project
• Design: Custom-engineered around tunnel geometry, clearances, and work requirements

Final platform geometry, access arrangement, mobility method, loading, and support requirements should be reviewed against the tunnel conditions and intended work activity before manufacture.
