VIBRO RIPPER
THE ULTIMATE IN PRODUCTIVITY
BULLSTERN RIPPER is normally applied in areas, where drilling and blasting with explosives is not permitted for safety and environmental reasons or simply more expensive. Also, suitable for demolition, mining, etc. It exceeds the hydraulic breaker production in 80% of job applications.
KEY BENEFITS
- 3 to 5 times higher productivity than hydraulic breakers
- Less disturbance of the surroundings (noise & dust)
- Bigger and heavier eccentric gears to maximize impact power
- Easy maintenance & better workability
KEY FEATURES
- Symmetrical arrangement of eccentric weights on both sides of gears vertically, two gears in serial with four eccentric weights in total
- Single link connection provides for easy maintenance access
- Dual air springs with stud bumps on housing results in greater shock reduction to hydraulic excavator
- Balanced sliding gear housing on guide rollers in the front and rear
- Vertical direction impact force concentrated and centralized into single point
- Optional compatible tool holder for both tooth and chisel
VIBRO RIPPER IN ACTION
BULLSTERN VIBRO RIPPER – One-Link Sliding Mechanism Technical Overview
1. Adaptive Load Distribution System
The one-link sliding mechanism allows the main link to shift along a controlled path during vibration. This movement disperses impact forces across multiple contact points instead of concentrating them in a single area, significantly reducing peak stress on the housing and eccentric module.
2. Effective Vibration Damping & Shock Absorption
As the link slides during each vibration cycle, micro-movements absorb a portion of the transmitted shock. This reduces secondary vibration transfer to the excavator boom, minimizes metal fatigue, and enhances the service life of structural welds and key components.
3. Reduced Wear on Pivoting Components
The sliding motion prevents repetitive loading on the same bearing or pin surfaces. By distributing friction over a wider area, the system reduces surface scoring, lowers heat generation, and extends lubrication intervals.
4. Enhanced Durability Under Hard Rock Conditions
Unlike fixed-link systems that suffer from direct impact loading, the one-link sliding design tolerates sudden load spikes caused by hard rock or uneven material. This allows the vibro ripper to maintain consistent performance even in highly variable geological conditions.
5. Stabilized Operating Rhythm at High RPM
The mechanism maintains a stable oscillation profile at high vibration frequencies. This stability improves penetration efficiency, reduces unnecessary machine resonance, and contributes to faster cycle times.
6. Engineered to Protect the Eccentric Assembly
By keeping peak loads away from the eccentric shaft and counterweights, the structure minimizes the risk of micro-cracks and bearing overload.
7. Proven & Patented Structural Concept
BULLSTERN’s one-link sliding mechanism is protected by patent, reflecting its distinct engineering approach to impact management, durability, and long-term reliability.
