DYB Series By maximizing demolition power and durability, DONGYANG breakers will make your working efficiency higher at the construction field.

3 DYB Series By maximizing demolition power and durability, DONGYANG breakers will make your working efficiency higher at the construction field. Harmonized combination of hydraulic oil & N2 gas Minimized internal torque for long life expectancy Low-maintenance & fewer components Maximized operating efficiency Balanced power-to-weight ratio Environment-friendly system More impact power A better design that combining efficiency, reliability and serviceability. Unique nitrogen gas-powered pis maximizes haer efficiency Bottom tie rod nuts for easier serviceability Quick-change tool system with single round retainer pin, up to DYB-300 Variety of tool configurations available Replaceable cylinder bushings for easy, economical rebuild Tool bushings engineered for quick, easy replacement Simplified lubrication for greater reliability Greasing port is provided for automatic and/or manual greasing of the demolition tool. This prevents damage or premature wear caused by a lack of grease. Full serviceability of the industry's easiest, lowest cost, body-rebuild system Haers aren't meant to have an easy life. They occasionally need to be rebuilt. When the haer body is involved, DONGYANG's replaceable bushing design can reduce your costs by a factor of five to ten.
