Chile, a long, narrow country stretching along the west coast of South America, holds the world’s richest copper mineral resources. Its copper reserves account for nearly one-third of the global total, and it is also a major producer of lithium, molybdenum, gold, and other minerals. The Andes Mountains, dotted with mines and continuously expanding urban construction, keep Chile’s demand for construction machinery and attachments strong all year round.
On mine and construction sites, crushing work is often the key factor holding back construction progress. Insufficient impact force of equipment leads to low working efficiency; frequent breakdowns cause losses from work stoppages; mismatched models with excavators speed up damage to main machines. These problems are especially prominent in Chile’s harsh mining areas.
The side type hydraulic rock hammer launched by YG Machinery delivers a reliable solution for Chilean users, featuring a compact structure design, direct impact force transmission, and easy maintenance. From highland copper mines in Antofagasta to municipal demolition sites in Santiago, YG’s hydraulic rock breaker machine proves its value with real working performance.

Case 1: Application of Hydraulic Rock Hammer in Copper Mines of Northern Chile
Client Background
The client is a medium-sized copper mining enterprise located in the Antofagasta Region of northern Chile. The mine sits at an altitude of around 3,000 meters and mainly mines copper oxide ore. After daily blasting work, massive ore blocks over 800mm in diameter are produced, which must undergo secondary crushing before being sent to jaw crushers in mineral processing plants.
Client Requirements
The client needed a hydraulic excavator hammer that could run stably in high-altitude environments. It required strong continuous working capacity, low failure rates and simple maintenance, and had to match their three existing 20-ton excavators. The client also emphasized that crushed ore particle size must stay within 300mm; otherwise, the jaw crusher feed inlet would get blocked.
YG Solution
After analyzing the client’s working conditions, YG’s technical team recommended the YGB1600S side type hydraulic rock hammer. This model weighs 1600kg, fits 19–26 ton excavators, comes with a 135mm chisel, working pressure of 160–180 bar, flow rate of 120–160 L/min, and impact rate of 400–700 bpm. The 135mm chisel easily handles medium-hard rock in copper mines, while the 400–700 bpm impact rate ensures high crushing efficiency. The team also supplied reinforced chisels and high-temperature-resistant oil seals to cope with the mine’s huge temperature difference between day and night.
Project Process
The client learned about YG’s products through YG’s official website. After multiple rounds of email communication, YG’s sales team submitted detailed product technical documents and working condition matching reports. They gave precise model recommendations based on photos of rock samples and post-blasting ore size data provided by the client.
To ease the client’s worries about reduced impact force on plateaus, the YG team shared operation records of the same model working in mines at similar altitudes via remote video, along with complete equipment operation data. The client gained trust in YG’s professionalism. After around two weeks of business negotiations, they signed a purchase contract for two YGB1600S units.
Operation Results
Six months after putting the two YGB1600S units into service, feedback data from the client showed that each unit crushes roughly 120 tons of ore per day, about 25% higher than the previous brand’s equipment. The machines have run for a total of about 2,800 hours, with only one chisel replacement and two oil seal replacements. Downtime caused by malfunctions dropped by over 70%.
Case 2: Hydraulic Rock Hammer – A Transformative Choice for Santiago Municipal Demolition Company
Client Background
The client is a mid-sized municipal engineering firm based in Santiago, the capital of Chile. Its core businesses include old building demolition, urban road renovation, and pipeline trench excavation. The company previously relied on blasting to break concrete structures. However, blasting is strictly restricted in urban areas with long approval procedures. Besides, blasted concrete pieces have uneven sizes, bringing huge trouble for subsequent transportation and recycling. The company hoped to adopt a more flexible and controllable demolition method.
Client Requirements
The client needed a hydraulic rock breaker machine capable of efficiently breaking reinforced concrete. It needed to produce evenly sized concrete chunks for direct loading, transport, and later recycling. Moreover, job sites varied widely: building demolition in open spaces and road breaking in narrow alleys, so the equipment needed strong versatility and flexibility. The client planned to mount it on a 12-ton excavator.
YG Solution
YG recommended the YGB800S side type hydraulic rock hammer. This model weighs only 450kg with a total length of 1920mm, compatible with 7–14 ton excavators. It has an 85mm chisel, working pressure of 120–170 bar, flow rate of 60–100 L/min, and impact rate of 400–700 bpm. The 85mm chisel fully meets reinforced concrete crushing demands, and its lightweight 450kg design allows flexible operation even in narrow alleys.
To meet the client’s demand for uniform crushed material sizes, YG’s team recommended matching conical chisels. They effectively control crushing results to produce neat chunks for easy transport and recycling.
Project Process
After the client reached out to YG actively, the sales team held several in-depth talks via email and WhatsApp to fully understand the site environment and types of structures to be demolished. YG then delivered a complete equipment selection report, together with construction videos and crushing effect data of the same model on similar municipal demolition projects, helping the client see the real performance of YGB800S directly.
After comparing solutions from three different brands, the client found YG offered the best cost performance and fastest service response, and immediately placed an order for one YGB800S unit.
Operation Results
Four months after the equipment was put into use, the client reported: the YGB800S has run for about 1,200 hours fault-free, completing demolition of 3 old buildings and crushing work on around 2 kilometers of urban roads. Crushed concrete chunks are evenly sized, with over 95% smaller than 200mm. They can be directly loaded onto trucks and sent to recycling stations for reprocessing, removing the need for secondary crushing. Overall construction efficiency rose by roughly 40% compared with the old blasting method.
From highland copper mines in Antofagasta to urban demolition sites in Santiago, YG’s side type excavator breaker machine is serving more and more construction projects across Chile. Whether for mining work or municipal demolition, YG side type hydraulic breakers win recognition from Chilean users thanks to precise tonnage matching, stable impact performance, and user-friendly maintenance design.
