LT-C0660 Flexural Frame, Four-Column Type | 600 kN
600 kN Flexural Testing Frame is designed for flexural and related mechanical testing of large and heavy concrete specimens. The LT-C0660 features a rigid four-column high-stability loading frame with a maximum capacity of 600 kN. Its double-acting ram provides a maximum stroke of 420 mm, while the robust frame construction helps maintain stability under high loads. A load cell measures the applied force accurately during testing. Special specimen loading equipment, a 1.5-ton scissor jack, and a roller-based flexural test assembly support the handling and testing of heavy specimens.

600 kN Flexural Frame for Controlled Concrete Testing
The 600 kN Flexural Frame provides a stable loading platform for testing large and heavy concrete specimens. The LT-C0660 uses a rigid four-column structure to maintain mechanical stability during demanding test applications. This design helps reduce unwanted movement while the system applies load to the specimen.
The frame is particularly suitable for flexural strength testing. EN 12390-5 describes the determination of flexural strength for hardened concrete specimens. In addition, ASTM C78/C78M covers flexural testing of concrete beams using third-point loading.
Rigid Four-Column Frame Design
The four-column structure transfers the applied load through a strong and stable frame. The ram system mounted on the upper section applies force to the specimen in a controlled manner. In addition, the rigid construction supports stable operation at high load levels.
The LT-C0660 offers a maximum capacity of 600 kN. It also provides Class 1 accuracy from 2% of full capacity. A load cell measures the applied force during each test and supports reliable data acquisition.
Double-Acting Ram and Safety System
The machine uses a double-acting ram with a maximum stroke of 420 mm. This wide travel range provides additional adjustment flexibility for different specimen geometries.
A safety limit switch also controls the ram at its maximum stroke position. When the ram reaches the defined travel limit, the system helps protect the equipment from excessive movement.
Special Equipment for Heavy Specimens
Handling large concrete specimens requires a controlled loading process. Therefore, the system includes special equipment for positioning heavy test pieces within the frame.
A 1.5-ton scissor jack supports specimen positioning and adjustment. This equipment helps the operator move heavy specimens into the correct testing position more efficiently.
Flexural Testing Assembly
The machine includes a flexural test assembly with 2 upper and 2 lower rollers. Each roller measures Ø40 × 420 mm. The wide adjustment range between the rollers supports testing of concrete elements with different dimensions.
ASTM C293/C293M describes flexural strength testing of concrete specimens using center-point loading. In contrast, ASTM C78/C78M uses third-point loading. Therefore, laboratories should configure the test arrangement according to the required standard and specimen type.
High-Stability Laboratory Testing
The system combines high load capacity with generous testing clearances. The maximum horizontal clearance between the columns reaches 1640 mm in the special specimen loading direction. In the other direction, the available clearance is 1500 mm. The lower roller spacing can reach up to 2360 mm.
These dimensions provide laboratories with flexibility when working with large concrete elements. In addition, the special loading equipment helps simplify specimen handling.
As a result, the 600 kN Flexural Frame combines high mechanical stability, accurate load measurement and heavy-specimen handling equipment in a single testing system. The LT-C0660 provides a comprehensive solution for laboratories that perform controlled and repeatable flexural testing on large concrete specimens.
