Guide to Hydraulic Hammers and Their Different Parts

Time: 2025-07-25 13:13

Behind the power of a hydraulic breaker lies a series of highly specialized components working in sync. From the nitrogen-charged back head to the hardened chisel tip, each part of the hydraulic hammer is designed to maximize impact efficiency while minimizing vibration and wear.

At BEILITE, every hydraulic breaker for excavator or skid steer hammer is built with durability in mind. Our BLT and BLTB series are engineered for mining, demolition, tunneling, underwater, high-altitude, high temperature, extreme cold weather working site, ect. By understanding the role of each component, contractors can choose the right hydraulic hammer for excavator, troubleshoot faults faster, and extend the tool’s service life.

What Are the Main Parts of a Hydraulic Hammer?

Back Head (Nitrogen Chamber)

The back head stores compressed nitrogen gas. It acts as a cushion that returns the piston after each blow, storing recoil energy and stabilizing the impact cycle.

Function: Energy storage and recoil buffering.
Common issue: Low nitrogen pressure leads to reduced impact force, especially in large hydraulic hammers used for mining or heavy demolition.

Cylinder

The cylinder is the main housing that guides the piston and defines the alignment of all moving parts.

Material: Hardened steel with extreme wear resistance.
Issue sign: Scoring or pitting inside the cylinder results in poor piston movement and lower efficiency—commonly seen in under-lubricated or overused hydraulic hammer units.

Piston

The piston delivers the actual impact. It moves back and forth inside the cylinder, driven by hydraulic oil pressure and nitrogen rebound.

Position: Between the valve and working tool.
Performance note: A worn piston in your hydraulic hammer for mini excavator will cause weak strikes and inconsistent operation.

Valve System (Control Valve)

This is the heart of the hydraulic cycle. The valve channels oil to the piston chambers, ensuring correct stroke timing.

Types: Internal (used in BEILITE BLT series) vs. external.
BEILITE feature: Our patented internal valve system enhances stroke frequency and improves efficiency in both mini excavator breaker models and larger excavator hammers.

Working Tool (Chisel)

The working tool makes direct contact with the material. Common types include:

Moil point: Versatile for general rock breaker use, especially in breaking up large, hard rock formations.
Flat chisel: Used for cracking rock or concrete, ideal for demolition work where precise cuts or controlled fracturing are needed.
Blunt tool: Primarily used in compacting and with skid steer concrete breaker attachments. Its flat end is perfect for tamping soil or breaking up soft materials without causing a lot of fragmentation.
Asphalt cutter: Ideal for trenching with a hydraulic breaker for skid steer, creating clean, straight cuts in asphalt or other paved surfaces.
Wide chisel: Used for cutting and breaking up soft rock and concrete, its broad edge provides a wider impact area for efficient demolition.

Proper lubrication and wear checks are essential. Skipping this will damage both the tool and bushings in your mini excavator rock breaker, leading to costly repairs and downtime. Regular maintenance, including daily greasing and inspecting for cracks or excessive wear, significantly extends the life of your equipment and ensures safe operation.

Bushings (Upper and Lower Tool Guides)

Bushings hold the tool in place and prevent the piston from taking side-loading stress.

Wear symptom: Excessive tool play or wobble—especially in high-frequency units like a skid steer hammer.
BEILITE benefit: Our replaceable bushings are heat-treated to extend service intervals.

Accumulator (Optional on Some Models)

In high-capacity hammers, such as the BLTB-200, the accumulator stores hydraulic energy and smooths out pressure spikes.

Application: Necessary in large excavator rock breaker units used for continuous mining or tunneling.
Result: Greater impact consistency and longer component life.

Housing (Outer Frame)

The housing protects the inner parts from impact and contamination. It also helps reduce noise and vibration.

Material: High-grade steel with anti-vibration mounts.
Variants: Soundproofed models are available for urban demolition, especially when using a hydraulic breaker for mini excavator for sale in residential or city work.

How Hydraulic Hammer Parts Work Together

Here's a simplified breakdown of the operating cycle using a BLT-100 hydraulic hammer for excavator:

Hydraulic oil flows into the valve.

The piston retracts, compressing nitrogen in the back head.
The valve shifts, sending oil to push the piston forward.
The piston hits the tool (e.g., moil point).
Energy transfers through the chisel to the rock or concrete.
Nitrogen rebounds the piston; the cycle restarts.

This rapid-fire process happens up to 1000 times per minute in models like our hydraulic hammer for sale for contractors needing high productivity.

Common Breaker Problems and the Parts Behind Them

Low impact energy: Often traced to low nitrogen in the back head or a worn piston in your excavator hammer for sale.
Oil leaks: Usually from worn seals around the valve or cylinder.
Noise/vibration: Caused by worn bushings or wrong tools used in a skid steer hammer.
Blow frequency drop: Blocked filters or incorrect oil supply.

BEILITE’s Engineering Advantage

We manufacture each component of our hydraulic breaker for sale in-house for quality control. This includes:
