Match the Hydraulic Breaker to Your Excavator Weight

The most important rule is to check your machine weight. A heavy attachment will make your mini excavator tip over. A light tool will not use the full power of your large excavator.

  • Mini Excavators (0.5 to 4.5 Tons): Models like YG350, YG400, YG450, and YG530 are perfect. They have a chisel diameter from 35mm to 53mm. They fit small garden works and pipe trenching.
  • Medium Excavators (6 to 15 Tons): Models like YG750, YG850, and YG100 offer great balance. They weigh between 210kg and 475kg. They are good for road repairs.
  • Large Excavators (18 to 80 Tons): Models like YG1400, YG1650, or the massive YG2100 are made for mining. They use high operating pressure to crush big rocks.

Check the Hydraulic Oil Flow and Operating Pressure

Every hydraulic rock breaker needs the correct oil flow and pressure from the carrier machine. If the oil flow is too high, the attachment will overheat and break. If the pressure is too low, the tool cannot strike hard enough.

  • Look at the hydraulic pump capacity: Check your excavator manual for the liters per minute (L/min). For example, our YG680 needs 40 to 70 L/min.
  • Check relief valve pressure: Your carrier pressure must match the tool pressure. YG models work from 90 Kg/cm² up to 240 Kg/cm².
  • Consider cooling systems: Continuous operation in hot weather requires a stable oil flow to prevent seal damage.

Choose the Right Chisel Design for Your Material

A professional rock breaker works best when you use the correct chisel type. Different jobs need different tips to transfer the striking energy into the ground.

  • Moil Point Chisel: This is a sharp point tip. It is best for soft rock, concrete floors, and general demolition jobs.
  • Chisel Point (Wedge): This looks like a flat screwdriver. It is excellent for trenching, cutting asphalt, and splitting layered rock.
  • Blunt Chisel: This is a flat, heavy end. It uses impact energy to crush big boulders in mining quarries.

Understand the Different Housing Types of Breakers

When you look for a breaker hammer for excavator machines, you will see three main housing styles. Each style has its own benefits for noise, budget, and protection.

  • Side Type Breakers: These have a short body design. They are very easy to maintain and great for close-up trench work.
  • Top Type Breakers: These provide a long straight line. They offer a long reach for high wall demolition and quarry crushing.
  • Box Type (Silenced) Breakers: These have a closed frame with sound isolation material. They create very low noise, which is mandatory for city construction.
