Among the numerous exhibits, the SR275E hybrid rotary drilling rig, with its leading technology of freely switching between three power modes: hybrid, plug-in, and pure battery, has become a highlight of the piling machinery section at this exhibition.

Based on the trust in equipment strength, Chongqing Zihang Construction Engineering Co., Ltd. ordered an SR275E hybrid rotary drilling rig at the exhibition site. This equipment is not only the first new energy pile driving machinery introduced by Chongqing Zihang, but also the first new generation SR275E electric rotary drilling rig to land in the southwest region.
