Tunnel Waterproof Board Laying Formwork Gantry
Tunnel waterproof board laying formwork gantry
This dual-purpose gantry handles automatic laying of tunnel waterproof membrane and the tying of secondary-lining reinforcement on a single platform. It addresses the safety, productivity and at-height issues of conventional membrane and rebar work in highway and railway tunnels.
Features
Lightweight design reduces self-weight and travel resistance; the membrane feed system avoids manual handling and re-rolling.
Retractable working platform provides full-face coverage.
Independent longitudinal travel and transverse translation simplifies positioning, calibration and crossing widened tunnel sections.
Hydraulic system controls transverse translation, four outriggers and the membrane lifting arm.
Wireless remote control of membrane laying, reinforcement lifting and gantry travel.
Plateau variant rated for operation up to 4,500 m altitude and -25 °C to +50 °C ambient.
