Engineering summary
A side-by-side look at QuakeLogic's large-scale shake tables, from a 500 kg compact platform to a 5 ton biaxial hydraulic system, with stroke, frequency and acceleration figures.
In short: QuakeLogic's shake table solutions span a 5 ton biaxial hydraulic table (2 m x 2 m, ±200 mm stroke, up to 50 Hz, ±1 g at full load), a 4.5 m x 1.5 m uniaxial servo-electric table (1,000 mm/s, 0.1 to 15 Hz), 1 to 3 ton servo-electromechanical tables, a 500 kg compact platform, and a 1.5 ton hydraulic table reaching 2.5 g, all with closed-loop PID control.
When you look at modern civil engineering, implementing reliable shake table solutions is absolutely non-negotiable. Replicating real-world earthquake motions requires precise, reliable, and high-performance testing platforms. Therefore, QuakeLogic stands at the forefront of this field by offering an advanced lineup of large-scale systems. These platforms are perfectly tailored to institutional research, public procurement, and advanced structural engineering. As a result, teams can easily execute complex dynamic testing in any environment.
Comprehensive Shake Table Solutions for Every Project
Different engineering projects naturally require diverse payload capacities. Because of this, QuakeLogic’s versatile portfolio guarantees a tailored structural testing platform for every single laboratory footprint.
High-Capacity Biaxial Shake Table Solutions
For large-scale structural models requiring multi-axis high-energy simulations, the QL – Biaxial Hydraulic Shake Table (5-Ton Capacity) offers an expansive 2 m × 2 m steel platform. This system delivers a ±200 mm stroke and operates at frequencies up to 50 Hz. Consequently, it achieves an impressive ±1 g acceleration even under a full 5-ton payload condition. Furthermore, it replicates severe earthquake ground motions with closed-loop PID precision. For more information on customization, check out the QuakeLogic Products.
Uniaxial Servo-Electric Shake Table Solutions
When long specimens require precise linear dynamic response analysis, the QL – Uniaxial Servo-Electric Shake Table provides an elongated 4.5 m x 1.5 m aluminum testing surface. By utilizing energy-efficient servo-electric drive technology, this system achieves peak velocities of 1,000 mm/s. Additionally, it operates over a 0.1–15 Hz frequency range with a ±200 mm stroke.
Sustainable and Maintenance-Free Testing Layouts
Many modern research facilities prefer avoiding the complexities of hydraulic fluids. For this reason, QuakeLogic offers robust servo-electro-mechanical shake table solutions that lower power consumption significantly:
- 3-Ton Systems: Features a 2 m x 2 m table size alongside an advanced IP-based control system for seamless remote operation.
- 2-Ton & 1-Ton Models: These turn-key platforms easily replay recorded earthquake data via intuitive PC software.
- 500 KG Platform: This compact 1500 mm x 1500 mm layout brings precise dynamic testing capabilities to limited laboratory spaces.
Meanwhile, if your project demands extreme acceleration profiles, the SHAKETABLE 1.5 TON HYDRAULIC delivers a massive 2.5 g acceleration. Thanks to its high-speed servo-hydraulic actuation reaching 1.2 m/s, it ensures unparalleled high-frequency replication accuracy. For global standards on earthquake testing methodologies, you can review the Earthquake Engineering Research Institute guidelines.
Turnkey Control and Data Integration
An advanced testing platform is only as good as its control system. Our shake table solutions feature closed-loop PID control architectures operable via advanced PC software. For instance, the systems natively support replaying historically recorded earthquake time-histories. Naturally, they also generate predefined waveforms like sine, triangle, and square shapes.
To ensure data-driven analysis, these testing systems integrate seamlessly with external data acquisition hardware. This setup includes the TESTBOX 2010 Digitizer, QL-VIBRA Accelerometers, and linear displacement transducers (LVDTs).

Frequently Asked Questions
A uniaxial shake table moves the specimen along one horizontal axis, which suits long specimens and linear dynamic response studies; QuakeLogic's servo-electric uniaxial table has a 4.5 m x 1.5 m surface for this purpose. A biaxial shake table drives two horizontal axes at once, reproducing the multi-directional ground motion of real earthquakes for large structural models, as the 5 ton 2 m x 2 m hydraulic system does.
Choose servo-electric or servo-electromechanical shake tables when the facility wants to avoid hydraulic fluid, pumps and the associated maintenance, and when lower power consumption matters. They cover payloads from 500 kg to 3 tons in QuakeLogic's range. Choose hydraulic tables when the test demands extreme acceleration, such as the 1.5 ton hydraulic table's 2.5 g at 1.2 m/s, or very high energy multi-axis motion.
Yes. QuakeLogic shake tables use closed-loop PID control and PC software that natively replays historically recorded earthquake time-histories, so a laboratory can subject a specimen to the same acceleration record measured during a real event. The same software also generates predefined sine, triangle and square waveforms for frequency sweeps and calibration runs.
The shake tables integrate with external data acquisition hardware, including the TESTBOX 2010 digitizer, QL-VIBRA accelerometers mounted on the specimen and table, and linear variable displacement transducers (LVDTs) for direct displacement measurement. This lets engineers compare commanded and achieved motion and capture the dynamic response of the test structure synchronously.
The 500 kg servo-electromechanical platform, with a 1,500 mm x 1,500 mm table, is QuakeLogic's compact option for limited laboratory floor space while still providing precise dynamic testing. The 1 ton and 2 ton turn-key models are the next step up, replaying recorded earthquake data through PC software without the infrastructure a hydraulic power unit requires.
