This SR4 hydraulic pile driver is a compact and highly efficient equipment specially designed for small and medium-sized projects. Its core power comes from a powerful engine with a power of 39 kilowatts, combined with a hydraulic system pressure of 20 Mpa, ensuring excellent impact force and operational stability. In terms of construction capabilities, this equipment can reach a maximum drilling depth of 2000 millimeters and can flexibly handle drilling tasks with diameters ranging from 50 to 300 millimeters, widely applicable to guardrail construction, photovoltaic piling, foundation reinforcement and other various conditions. Despite its powerful performance, the overall weight of the SR4 is controlled at 2800 kilograms. This design not only ensures the stability of the machine during construction, but also takes into account the convenience of transportation and relocation, giving it significant advantages in narrow spaces or projects requiring frequent movement of operations.
