The Kalimantan Dam Project is a key infrastructure development aimed at supporting regional water management and energy supply. The structure involves large-volume concrete casting, complex wall geometries, and high structural stability requirements, making it particularly demanding for formwork systems in terms of strength, adaptability, and durability.
To meet these challenges, the contractor selected Lianggong’s H20 Timber Beam Formwork System for the main wall and structural concrete works. The system demonstrated strong adaptability on site, especially in handling irregular and curved sections of the dam structure. Its flexible configuration allowed for efficient adjustments without complicated redesign, ensuring continuous workflow even under changing construction conditions.
Throughout the construction process, the timber beams and panels could be freely cut and reused, significantly improving material utilization. At the same time, the system maintained excellent load-bearing performance during large-scale concrete pouring, ensuring both safety and structural accuracy. The relatively lightweight components also made handling and installation more efficient, helping the project team accelerate the construction schedule.
In addition, the system delivered a high-quality concrete surface finish, reducing the need for extensive post-processing work. This not only improved overall construction efficiency but also contributed to better cost control across the project.
The successful application of the H20 Timber Beam Formwork System in the Kalimantan Dam Project highlights its reliability and versatility in large-scale infrastructure works, especially in projects requiring both structural strength and on-site flexibility.
The concrete pouring achieves not only qualified strength but also a smooth and level finish, eliminating the need for additional grinding work, which significantly improves overall construction efficiency.

Israel is characterized by sandy and loose soil in many areas. The Trench Box effectively mitigates the risk of trench collapse, while eliminating the need for extensive slope cutting in urban construction sites with limited space and dense underground utilities, thereby significantly reducing the volume of earth excavation
Ge adaptability:In certain areas of Israel , the soil is sandy and lacks self-standing capacity. Traditional open-cut with slope cutting is prone to collapse, making the trench box a highly efficient and safe solution.
Efficiency Advantages:Featuring a modular design, the trench box enables rapid assembly and lowering. Compared to steel sheet pile shoring, it offers faster construction speed and lower costs, along with zero vibration and low noise. It is ideally suited for urban construction environments.
Compliance Requirements:Israel’s construction safety codes mandate shoring support for deep trench operations. The trench box is a standard protective equipment that fully complies with local standards.

In a major healthcare infrastructure project in Trinidad and Tobago, LIANGGONG Hydraulic Auto-Climbing Formwork System (ACS) was successfully applied to the construction of the hospital’s reinforced concrete core structures and vertical shear walls. The project required high standards of safety, precision, and construction efficiency due to its complex structural design and tight schedule.
The hydraulic auto-climbing formwork system, powered by its integrated hydraulic lifting mechanism, enabled the entire formwork assembly to climb steadily without reliance on tower cranes or external lifting equipment. This significantly reduced crane usage on site while ensuring continuous and uninterrupted vertical construction. The system’s ability to allow synchronized or independent climbing of brackets and rails ensured smooth and stable operation throughout the project, even under challenging site conditions.
During construction, the system remained wall-attached and did not require dismantling or reinstallation at ground level, which optimized site space and minimized material damage. The integrated multi-level working platforms provided safe and efficient access for workers, eliminating the need for additional scaffolding and greatly improving overall site safety management.
The project team benefited from the high climbing efficiency of the ACS system, completing each structural level within a shortened cycle time and accelerating the overall construction schedule. At the same time, the system’s high construction accuracy allowed for easy alignment adjustment, ensuring that structural deviations were corrected floor by floor, meeting strict engineering tolerances required for hospital construction.
With its self-climbing capability, reduced labor intensity, and enhanced safety performance, the LIANGGONG Hydraulic Auto-Climbing Formwork System proved to be an ideal solution for this hospital project. The successful implementation not only ensured timely project delive
