Low Gas Type - Ramtec RD series is an excellent and stable hydraulic breakers. The product structure design has been tested by the market for a long time. After being carved by Ramtec technical team, the latest RD series has been developed, which has excellent high temperature resistance performance, fast frequency, strong impact force and excellent reaction force control. It has long been loved by the majority of construction machinery consumers. The parts are simple and easy to replace, and it is easier for the operator to maintain and replace the parts. The lightweight fuselage structure greatly reduces the load of the excavator, thereby increasing the service life of the hydraulic excavator and reducing the vibration and loss of the carrier. Due to its excellent resistance to high temperatures, it is a very suitable choice in areas with high construction temperatures.
