Introduction
The RSM-SLT(C) Small Load Static Tester is a next-generation intelligent testing device that integrates a lightweight high-pressure micro pump, wireless displacement sensors, and smart control modules. Supporting 0–500 kN tests, it delivers exceptional accuracy (control error ≤ 0.5 kN) for static load applications such as pile foundations, anchors, anchor bolts, and plate load tests. With features like automated loading/unloading, mobile app remote control, GPS positioning, and multi-sensor compatibility, it reduces on-site risks while ensuring reliable, efficient, and traceable data acquisition. The system complies with a wide range of international and domestic standards, and testing methods can be customized to specific regulatory requirements.
