Breaker Attachment for Excavator – YG Series Deployed in Peru

Project Overview: Breaker Attachment for Excavator Enters Peru Market

Peru is one of the world’s leading mining and construction markets, with extensive operations in the Andes Mountains. A Peruvian mining contractor operating a copper mine needed a reliable breaker attachment for an excavator to handle secondary rock breaking and oversize boulder reduction.

The contractor selected our YG series hydraulic hammer attachment – specifically the YG100 model – mounted on a 12-ton excavator. This machine arrived on-site in early 2026 and has been operating for over 5 months in high-altitude, hard rock conditions.

Site Conditions and Challenges for the Hydraulic Hammer Attachment

The Peruvian mine site presented several challenges for any breaker attachment for excavator:

• Hard andesite rock – compressive strength exceeding 150MPa
• High altitude – 3,800 meters above sea level, affecting cooling and power
• Oversize boulders – primary crusher feed required reduction below 600mm
• Limited working space – narrow benches in the open pit

Conventional blasting produced large boulders that jammed the crusher. The contractor needed a hydraulic hammer attachment that could break oversize efficiently without damaging the carrier.

Installation and Selection of the Breaker Attachment for Excavator

Our team helped the Peruvian contractor select the appropriate machine based on their 12-ton excavator and rock hardness. The YG100 machine was chosen for its optimal blow energy and frequency.

The machine installation included:

• Direct connection to excavator auxiliary hydraulics
• Pressure adjustment to 160 Kg/cm² for peak performance
• Flow setting at 95 L/min for 350-700 bpm

The attachment was tested on-site with a sample boulder, achieving full breakage within 30 seconds.

Operational Performance of the Hydraulic Hammer Attachment

Over 5 months of daily operation, the breaker attachment for excavator delivered consistent results. The attachment handled:

• Secondary rock breaking – reducing boulders from 1.2m to under 600mm
• Bench trimming – smoothing pit walls for safety
• Oversize removal – clearing crusher feed points

Performance data for the machine:

• Average daily breaking volume: 120-150 tons
• Blow frequency maintained at 400-500 bpm
• Fuel consumption: 8-10 L/hour on the excavator
• Downtime: zero unscheduled stops in 5 months

Why YG Hydraulic Hammer Attachment Suits Peruvian Mining?

The YG series machine offers distinct advantages for Peruvian conditions:

1. High impact energy – The attachment delivers powerful blows for hard andesite, matching the 150MPa rock strength.
2. Durable construction – Quality alloy steel and reliable seals ensure the breaker attachment for excavator resists wear in abrasive mining environments.
3. Wide model range – From YG350 for 0.5-ton mini excavators to YG2100 for 80-ton machines, this machine covers every carrier size.
4. Low maintenance – Modular design simplifies disassembly and parts replacement, reducing repair costs.
5. Multiple configurations – Available in silent, triangular, and right-angle types to suit different excavator arms and working positions.

Maintenance and Durability of the Breaker Attachment for Excavator

The hydraulic hammer attachment requires routine maintenance as per the manufacturer guidelines:

• Daily: Check chisel wear and hydraulic hose condition
• Weekly: Grease the tool shank and inspect accumulators
• Monthly: Check nitrogen pressure and bolt torque

The Peruvian contractor reports that the attachment consumes minimal wear parts – the chisel shows only 5mm reduction after 5 months of hard rock use. The machine benefits from robust sealing that prevents dust ingress even in dry, dusty mine conditions.
