Cantilever Form Traveller-Single Box Double Cells

Form Traveller Introduction

Single Box Double Cells Cantilever Form Traveller is a high-performance modular equipment designed for cantilever casting construction of double cells box beams. It is suitable for single-box double-cells cross-section box beam structures and is suitable for high-precision segment construction of large-span continuous beam bridges, continuous rigid frame bridges and wide bridges.

• Customized services: support dual-chamber asymmetric load optimization, deep-sea environment anti-corrosion enhancement, and intelligent digital construction system integration.

Form Traveller Core Advantages

• Dual-cell chamber collaborative load-bearing, more uniform load distribution, safety factor ≥3.0.
• Modular double-cells truss design, turnover rate ≥88%, comprehensive construction cost reduced by 25%.
• Millimeter-level dual-cell synchronous control, dual-cell linear error ≤1.5mm, ensures the forming accuracy of wide box beams.
• Full-condition stability, hydraulic synchronous walking error ≤0.5%, adapt to strong winds, tides and complex environments in earthquake zones.

Form Traveller Applicable scenarios

• Bridge types: cross-sea bridges, wide continuous beam bridges, double-span cable-stayed bridges, urban three-dimensional transportation hubs.
• Typical projects: cross-strait super-large bridges, heavy-load railway bridges, multi-lane highway wide bridges.
• Environmental tolerance: adapt to coastal high salt fog, high cold (-30℃) and high humidity tropical environments.
