Study Notes

Hydraulic breakers are powerful percussion hammers fitted to excavators for demolishing concrete structures or rocks.
Sany excavators are a brand of excavators, and hydraulic breakers can be attached to them to perform demolition or rock breaking tasks.
The sales features of hydraulic breakers suitable for Sany excavators are points that salespersons use to convince potential customers to purchase these hydraulic breakers for use with their Sany excavators.

Hydraulic Breaker Features: General

Impact energy determines the breaker's ability to fracture materials, measured in Joules (J).
Blow frequency affects the speed of demolition, measured in blows per minute (BPM).
Weight is a crucial factor for excavator compatibility and transportation.
Hydraulic flow rate compatibility with the Sany excavator's hydraulic system is essential.
Tool diameter influences the size and type of material that can be broken.
Noise level is an environmental consideration, with silenced breakers being preferred in urban areas.

High impact energy for efficient breaking of hard materials.
Optimized blow frequency for faster demolition rates.
Adjustable impact force and frequency to match the material being broken.
Anti-blank firing system prevents damage by stopping the breaker when it's not pressed against material.
Stroke Adjustment: Adjust the stroke to reach the material needing breaking
