Pile Dynamic Load Testing Equipment Deep Foundation Bearing Capacity Testing Pile Load Capacity Testing Instrument Load Testing Piles Driving Analyzer 
In the high strain method, a vertical transient impact load is applied to the pile top by the hammering system. The force acting on the pile top is close to the actual stress level of the pile, resulting in significant acceleration and inertia force. The strain of the pile body is equivalent to the strain level of the engineering pile. The impact force causes relative displacement between the pile and soil, so as to give full play to the pile side friction and stimulate the end resistance accordingly, Force and acceleration sensors are symmetrically installed on both sides of the pile at a certain distance from the pile top to measure the force and the response signal of the pile-soil system. The hammer response signal (pile strain stress curve and pile particle motion speed curve) is received through the foundation pile dynamic tester. Its dynamic response signal not only reflects the pile-soil characteristics, but also is closely related to the dynamic load intensity, spectrum composition and duration, Thus, the bearing capacity of single pile and the structural integrity of pile body are calculated and analyzed.
