Hydraulic Breaker Main Body: Engineered for Reliability and
Performance
Product Introduction
The Main Body Assembly is a vital component of hydraulic hammers
for construction machinery, especially backhoe loaders. As the
central structure, it houses key elements including the piston,
cylinder, and chisel, ensuring optimal alignment and performance.
Designed for durability and reliability, the main body assembly
enables hydraulic hammers to deliver powerful and efficient
operation in tough applications such as rock breaking, concrete
demolition, and mining. Choosing a high-quality main body assembly
maximizes the lifespan and productivity of your hydraulic hammer,
making it an essential part for construction and mining equipment.
Key Features
Material:
The main body assembly is constructed from high-strength steel
alloys such as 42CrMn, ensuring exceptional durability, wear
resistance, and a long service life in demanding environments.
Advanced Design:
Engineered to withstand extreme impact forces, the main body
assembly offers superior structural integrity and reliable
performance, even under harsh operating conditions commonly found
in construction, demolition, and mining applications.
Wide Compatibility:
Available in a range of models—including HB10G, HB15G, HB20G,
HB30G, and HB40G—the main body assembly is designed to fit various
hydraulic hammer sizes, making it the ideal choice for different
types of construction and mining machinery.
