In modern construction, critical infrastructure projects such as airports, railroads, subways, wharves, and high-rise buildings demand precise and reliable foundation testing. Any compromise in pile foundation quality can lead to safety risks, costly delays, and structural failures. KEDA, a leading manufacturer specializing in intelligent load box solutions, provides pipe pile load boxes and reverse cycle load boxes that deliver high-precision, stable, and actionable data for foundation pile testing.

With decades of experience in the industry, KEDA has earned international recognition for its advanced manufacturing processes, accurate testing data, and reliable product performance. The company’s load boxes are widely used in projects where foundation integrity is paramount, helping engineers and project managers make informed decisions for safety and efficiency.

What Are Pipe and Reverse Cycle Load Boxes?

Pipe Pile Load Boxes

Pipe pile load boxes are designed to measure axial and lateral forces on foundation piles with exceptional precision. They are particularly suitable for:

Subway and metro construction, where urban soil conditions require accurate load data.
Airports and railroad projects, which must handle heavy dynamic loads.
High-rise buildings and commercial real estate, where foundation accuracy ensures structural stability.

Key Features of Pipe Pile Load Boxes:

High measurement accuracy for both static and dynamic loads
Durable construction for long-term field deployment
Adaptability to various pile types, including rotary, helical, and pipe piles
Integration with intelligent data acquisition systems for real-time monitoring

Reverse Cycle Load Boxes

Reverse cycle load boxes provide bi-directional load testing, simulating real-world stresses by applying controlled upward and downward cycles. This type of load box is essential for projects where dynamic load response must be evaluated.

Applications of Reverse Cycle Load Boxes:

Critical transportation hubs like airports and railway stations
Ports and wharves, which face variable lateral and axial loads
Industrial and high-rise foundations requiring detailed soil-pile interaction data

Advantages:

Bi-directional load testing reveals pile behavior under realistic conditions
Enhanced accuracy for dynamic load analysis
Reliable under repeated testing cycles, ensuring long-term data integrity
