The CB-180 and CB-240 cantilever climbing formwork systems are primarily used for large-volume concrete structures including retaining walls, dams, anchors, piers, tunnels, and basements. Concrete lateral pressure is transferred through anchors and high-strength tie rods, eliminating requirement for additional formwork reinforcement. Key characteristics encompass simple operation, adjustable single-pour height capacity, superior concrete finish, cost efficiency, and structural durability.
The CB-240 cantilever formwork provides two lifting unit options: diagonal brace type and truss type. The truss type configuration demonstrates enhanced performance in high-load applications, increased vertical construction heights, and minimal inclination scenarios.
The principal distinction between CB-180 and CB-240 lies in the main brackets, with primary platform widths measuring 180 cm and 240 cm respectively.
ltem | Diagonal brace type | Truss type |
Max pouring height | 4.5m | 6m |
Load-bearing capacity | Moderate | Heavy |
Adjustability | Vertical+ Horizontal adjustment | Vertical+ Horizontal + Diagonal brace tilt adjustment |
Retractable stroke | 600mm | 600mm |
Accuracy requirement for anchor system installation | Allowable error of embedded position ≤ 3mm | Allowable error of embedded position ≤ 1mm with stricter accuracy requirements |
Application scope | More suitable for straight wall structures with conventional height and stable load | Suitable for high-altitude operations requiring higher pouring heights and high formwork adjustment accuracy, with stronger versatility |
Bracket, formwork and construction load are fully borne by embedded anchors and wall-through tie rods. No additional scaffolding is required, enabling safe high-altitude construction.
Maximum concreting height reaches 6 meters. The entire cantilever formwork can be retracted 600 mm horizontally.
The cantilever formwork unit adjusts vertically/laterally relative to supporting brackets. Diagonal brace type formwork additionally tilts forward/backward.
All connecting parts feature high standardization and versatility.
Cantilever formwork adjusts to tightly seal against concrete surfaces, preventing grout leakage and joint misalignment.
The cantilever climbing bracket system includes suspended platforms for anchoring parts removal and concrete surface treatment.
