In the mining and aggregate industry, a Pedestal Rockbreaker Boom System is not just an accessory; it is your primary insurance policy against downtime. However, selecting the wrong system can be a costly mistake. A boom that is too short leaves dangerous "blind spots" in the crusher box, while a system that is oversized wastes capital and energy.
Since 2002, Jinan YZH Machinery Equipment Co., Ltd. has engineered custom solutions for thousands of quarries and mines. We know that the "perfect fit" isn't a guess—it's a calculation.
Whether you are outfitting a new primary station or retrofitting an aging plant, this guide outlines the 7 critical engineering factors you must evaluate to choose the right Pedestal Rockbreaker Boom System.
How do I choose the right pedestal rock breaker?To select the correct system, you must match the boom's Working Envelope to your crusher's dimensions and the Hammer's Impact Energy to your rock hardness.
Crusher Type: Jaw (requires 4-8m reach) vs. Gyratory (requires 8-15m reach).
Rock Hardness: Soft limestone needs frequency; hard granite needs high Joules (3,000J+).
Reach: The boom must reach the "bridging point" deep in the throat, not just the feeder.
Duty Cycle: How often will it run? (Light <5/week vs. Heavy >20/week).
The design of your crusher dictates the kinematics of the boom.
Jaw Crushers: These typically require a boom with a shorter reach but high articulation to poke and rake material into the jaw. Our YZH-B Series (4m–8m) is engineered specifically for this, allowing the breaker to fold compactly when not in use.
Gyratory Crushers: These massive primary crushers require long-reach systems that can rotate 360 degrees to cover the entire bowl. The YZH-G Series (8m–15m) provides the necessary reach to clear bridges on the far side of the spider arm.
Grizzly Bars: For raking oversized material off a grizzly, a linear travel system (YZH-R Series) is often more effective than a rotating boom.
You are not just breaking rock; you are breaking specific rock.
The 95th Percentile Rule: Measure the size of the largest rocks that typically enter your crusher (the 95th percentile). The hydraulic hammer must be physically large enough to position these rocks.
Hardness (MPa): The compressive strength of your rock determines the hammer size.
Soft/Medium Rock: Requires a lighter hammer with a faster blow frequency.
Hard/Abrasive Rock: Requires a heavy-duty hammer with high impact energy to fracture the stone.
"Reach" is not just a straight line; it is a 3D volume.
When evaluating a Stationary Rock Breaker, you must calculate the vertical depth. Can the breaker tool reach the bottom of the crusher chamber where jams often occur?
Recommendation: YZH engineers use 3D simulation to plot the "Working Envelope." We ensure the tool point can reach the feeder, the crusher throat, and the maintenance area, without striking the crusher liners.
The boom moves the tool, but the hammer does the work.
Selecting the wrong hammer results in bouncing (too light) or damage to the boom (too heavy).
1,500 – 2,500 Joules: Ideal for smaller jaw crushers and softer aggregates.
3,000 – 6,000 Joules: Required for large gyratory crushers and hard rock mining (Granite, Basalt, Iron Ore).
Is your rock breaker an "Emergency Tool" or a "Production Tool"?
Light Duty (<5 uses/week): If you have consistent blasting and rare blockages, a standard pedestal system is cost-effective.
Heavy Duty (>20 uses/week): If your operation relies on the breaker to oversize material constantly, you need a "Production Class" system with reinforced pivot points, larger pins, and an auto-greasing system to withstand the constant stress.
Safety is the primary driver for installing a pedestal boom. How will your team operate it?
Radio Remote: Allows the operator to walk around the platform for a better view (Standard on most YZH Boom Systems).
Cab/Control Room: For high-dust environments, the system is integrated into the operator's cabin via joystick.
Smart Integration: We can integrate the boom into your plant's SCADA system, ensuring the crusher feeder stops automatically when the boom is active.
Don't guess. Let us calculate.
At YZH Machinery, we don't just sell part numbers. We follow a strict ISO 9001 engineering process to ensure your investment performs for decades:
Site Assessment: We analyze your crusher drawings and plant layout.
3D Simulation: We simulate the boom's movement in your specific crusher to guarantee zero blind spots.
Custom Design: From 4-meter compact units to 15-meter giants, we build the system that fits your mine.

Q1: How do I measure the required reach for my rock breaker boom?
A: Measure the horizontal distance from the proposed mounting point to the furthest corner of the crusher box, and the vertical distance to the bottom of the crushing chamber. YZH recommends adding a 10% buffer to this measurement.
Q2: Can YZH pedestal booms be installed on existing steelwork?
A: Yes, but the steelwork must be reinforced to handle the dynamic loads (vibration and torque) of the boom. YZH provides load data sheets to help your structural engineers verify the support.
Q3: What is the difference between the YZH-B and YZH-G series?
A: The YZH-B Series is optimized for Jaw Crushers with a focus on articulation and poking. The YZH-G Series is designed for Gyratory Crushers, featuring longer reach, heavier lifting capacity, and 360-degree rotation.
Q4: Does the system come with a hydraulic power pack?
A: Yes. All YZH systems are delivered as a complete package, including the boom arm, hydraulic hammer, electric-hydraulic power unit, control console, and piping.
