Dynamic X Rock Plate
The new Dynamic X-Plate from Sandvik is specifically developed to offer cutting-edge ground support in seismic ground conditions, and to complement the MDX bolts.
The Sandvik X-Plate can absorb more energy thanks to its stronger plate and improved design, compared to current versions of the rock plates and combination plates, while at the same time being a thinner material. Test results, conducted in both static and dynamic test rigs, show that the X-Plate can absorb 22% more load than a standard product in static loading conditions, and 54% more energy in dynamic loading conditions.
- State-of-the art rock plate, designed to improve performance in seismic conditions
- Increased product strength during a seismic event providing more energy absorption
- A more sustainable solution. The X-Plate requires 14% less steel in manufacturing, which represents great CO2 savings in both manufacturing and shipping
- When tested in accordance with ASMT F432-19, the X-plate meets grade rating ‘4’.
Dynamic Test Rig
To enhance the testing of Sandvik Rock Tools ground support offering, a dynamic test rig has been designed and built at the Rock Tools site in Heatherbrae, Australia. It can test the load and displacement capabilities of several different products, such as rock plates, bolt components and soon also for full-scale bolts. A high-speed camera captures a video of the test up to 1800 images per second that allows for displacement extrapolation. Not only can the dynamic test rig be used to calculate displacement, a load cell also measures and records the load applied to the plate in 25 000 hz. All in all, the dynamic test rig provides outstanding evaluation possibilities and very precise data.
