Vibrating ripper YG series

Overview
A vibrating ripper uses high-frequency vibration combined with ripping force to fracture weathered and jointed rock, increasing rock removal rates while reducing hydraulic oil temperature and boom shock compared with single-piston breakers.

Performance & Benefits

• Typical productivity improvements of 3–5× in fractured materials (field data for red sandstone, weathered rock and gypsum).
• Lower hydraulic oil temperatures and reduced boom stress when correctly matched to the carrier.
• Lower operational failure rates and easier tooth maintenance with boltable tooth caps.

Field Tips

• Set the tooth at a shallow angle and drag to let vibration propagate through seams rather than driving straight down.
• On jointed limestone, align the blade with natural faults to speed breakage.
• Check pin locks every 4 operating hours and grease the eccentric gear housing regularly.

How it Works
Hydraulic drive components produce high-frequency vibration while the ripper applies a pulling/ripping action. The vibration induces internal fractures and the ripping extracts broken rock, delivering faster advance in fractured or weathered strata than conventional breakers.

Typical Applications

• Open-pit quarries: efficient ripping of sandstone, shale and limestone without explosives.
• Underwater trenching: sealed housings operate against hydrostatic pressure.
• Frozen ground & gypsum mining: effective on permafrost and mineral beds.
• Site preparation & land clearing: combined use with stump shears or concrete pulverizers.

How to Match a Vibrating Ripper to Excavator Size
Selecting the correct carrier and hydraulic flow protects the pump and maximizes rock-breaking force. Typical model-match guidelines:

• Medium Excavators (20–29 Tons): YG-30, YG-40 — 120–170 L/min, ~3000–3300 kg.
• Heavy Excavators (30–46 Tons): YG-50, YG-60 — 175–250 L/min, ~4900–5200 kg.
• Severe Mining Excavators (46–90 Tons): YG-70, YG-80 — 280–450 L/min, ~6800–9600 kg.

Field Case Summary
In one quarry retrofit, replacing a standard hydraulic hammer with a YG-60 on a 36 t excavator increased daily output from ~300 t/day to >1000 t/day, reduced per-ton fuel consumption by ~20% and lowered maintenance costs by ~35% due to reduced boom stress and lower hydraulic temperatures.

YG-50 | 30–36 | 175–210 | 260–315 | 4900
YG-60 | 36–46 | 215–250 | 260–315 | 5200
YG-70 | 46–60 | 280–345 | 260–315 | 6800
YG-80 | 60–90 | 350–450 | 260–315 | 9600

FAQs

• How does a vibrating ripper differ from a hydraulic breaker? — A breaker uses piston impacts; the vibrating ripper uses high-frequency vibration plus ripping action to fracture and pull rock, outperforming breakers in fractured materials.
• Will vibration damage the excavator boom? — When the unit is correctly sized and installed, shock-absorption components limit transmitted recoil and protect the carrier.
• How are worn teeth maintained? — Tooth tips are cast from wear-resistant alloy; worn tips are welded or replaced via boltable caps on site.
