The Sangdo SD140 (often referred to as the SD140S in its silenced/box version) is a medium-range hydraulic breaker designed for mid-sized excavators.
It is well-regarded for its balance of impact power and durability in rock breaking, demolition, and trenching.
Below are the primary technical specifications for the unit:
