In tunnel construction—whether for highways, railways, hydropower stations or municipal projects—the secondary lining concrete pouring is a critical phase that demands precision, efficiency and reliability. Traditional lining methods often suffer from high labor costs, slow progress and inconsistent concrete quality. That’s where Lianggong’s Hydraulic Tunnel Lining Trolley comes in—an equipment designed to redefine tunnel lining operations with advanced hydraulic technology, robust structure and user-centric design.
Why Our Hydraulic Tunnel Lining Trolley Outperforms Traditional Methods?
● Hydraulic Transmission Advantage: Adopts hydraulic drive to simplify the frame structure and reduce weight by over 40% compared to mechanical trolleys. It enhances operational flexibility and diversity, with precise adjustments for lateral, horizontal and lifting movements to ensure formwork alignment.
● Cost-Effective & Efficient: Lowers production costs by over 25% while significantly reducing labor demand. Cooperating with auxiliary machinery, it boosts the mechanization rate of secondary lining construction, accelerating project progress substantially.
● Superior Structural Stability: Features a 9m four-door, 12m main portal structure (optimized through strength calculation and scheme comparison). Equipped with lateral hydraulic cylinders, lateral support jacks and portal-frame support jacks, it resists vertical/lateral pressure and buoyancy during concrete pouring, minimizing deformation under force.
● Precise & Smooth Forming: High-quality steel mold with strict processing and welding processes—using special assembled welding jigs to control dimensional accuracy and welding distortion. Interference-fit stabilizing pins fix adjacent template connecting plates, effectively preventing misalignment and ensuring a smooth, defect-free tunnel lining surface.
● Strong Reusability & Versatility: Available in multiple specifications (6m, 7.5m, 9m, 10.5m, 12m) to match tunnel lengths and construction schedules. Classified into side&roof arch type, fully round acerate-beam type, bottom platform needle-beam type and fully round through type, adapting to diverse tunnel structures.
● Spacious Operational Environment: Provides adequate space under the trolley, facilitating reinforcement binding and formwork construction operations—improving on-site work efficiency and safety.

What Is Working Principle of Hydraulic Tunnel Lining Trolley?
● The trolley’s total weight is transmitted through the steel mold to the support mechanism and then to the portal frame.
● During concrete pouring, the solid-liquid state concrete generates vertical/lateral pressure on the top and sides, along with buoyancy.
● Optimized support positions (lower longitudinal beams supported on the ground, horizontal supports between portal frame and side form longitudinal beams, straight supports at upper beams) counteract pressure and buoyancy.
● Hydraulic cylinders are locked by hydraulic locks and supporting screws provide mechanical fixation—preventing cylinder retraction and template deformation during lining construction.
