The production goal for the contractor was to lay five 20 ft length sections of pipe per five-day work week.
The site required a trench to be dug through very dense limestone rated between 16,000 and 22,000psi. The contractor tried many other conventional trenching methods, but none of them were able to keep up with production goals and keep project costs in line with the budget. For example, while using a hydraulic breaker, they struggled to lay one 20 ft length of 36 in diameter pipe in a week, far short of the five sections goal required.

In the heart of one of the world’s largest cities you can feel and hear the energy on the busy streets, when suddenly between the traffic jam of vehicles and the masses of people on the sidewalk, there is a Hitachi Tata 700 excavator. On the end of this massive 70 metric ton machine is an AQ-5 Antraquip rock grinder which is one of world’s most powerful drum cutters on the market (Antraquip’s 2nd largest model).
The challenge for this project was the excavation of dozens of narrow shafts that are spaced every couple of hundred meters, allowing the mini… Read More
At the end of December 2017, Antraquip delivered three (3) of their powerful AQ-5 drum cutters to one of their most longstanding customers in New England with plenty of experience utilizing Antraquip attachments for a variety of projects over the years.
For this job however, the contractor was on a particularly tight timeline to complete the controlled concrete demolition of wall within a lock which would need to reopen by Spring to allow large ships to pass through the vital waterway to access the major cities in the northeastern part of the US and Canada. The customer mounted the AQ-5s on… Read More
An Antraquip AQ-6 was put into operation by a major Canadian contractor in February of 2017 to excavate a shaft and drive a ventilation tunnel in downtown Montreal.The rock hardness on this project was above and beyond what is traditionally considered as suitable for mechanized excavation (ie. roadheader, drumcutter etc.). After careful collaboration between Antraquip and the contractor the AQ-6 was boom mounted on a CAT365 excavator, driven via hydraulic power unit, and put to work under the busy streets of Montreal.
The ~8 metric ton cutter, capable of delivering 400kW output power did not disappoint as the shaft and… Read More

A happy project manager on the line speaks about our smallest transverse model designed to operate on mini-excavators and other compact hydraulic carriers.
The company says the Antraquip range of attachments—US-built to work harder and last longer—can provide customer engineered solutions for any rock or concrete cutting project. They can also deliver viable economic and environmental alternatives to blasting or hammering. Read More
Starting in June, Antraquip supplied an AQ-5 cutter mounted on a CAT349, an AQC180 carbide saw (rockwheel) for a CAT336 and shortly thereafter sent in another AQ-4 cutter for a CAT330 onto the campus of the prestigious Yale University. These attachments are being used to excavate more than 100,000 cubic meters of rock that consists of limestone, sandstone and shale with UCS of ranging from 6,000 to 12,000psi (40-85MPa).
The project started out with another head to head comparison of the Antraquip AQ-5 compared to competitor model mounted on the same CAT349 excavator and as has been showcased before… Read More
Successful Land Development Project in Western PennsylvaniaRecently, a well known contractor in western Pennsylvania was needing an efficient rock excavation method for a land development project on the back portion of his property. Drilling and blasting was not allowed given the close proximity to neighborhoods and hydraulic breakers were also very loud and not productive enough to complete the project on schedule. The client was familiar with hydraulic cutters having successfully used them on various trenching projects but wanted a comparison of production rates of the Antraquip AQ-5 and a regional competitor importing a similar machine from overseas. He diligently… Read More

Here's How this local excavating contractor turned what appeared to be a "Money losing, equipment breaking project"... Into a profit producing win/win project for his company and client.
The project called for the bidding of 4 large concrete bridge abutments. In the past the contractor would simply bid estimating a 3 weeks lead time per one side (8 sides total)
"We've been running a CAT 325 excavators with hydraulic breakers on the end"...
"However on this project we felt there has to be a faster more cost effective way to preform the demolition/removal of these 4 concrete bridge abutments."
I asked...How would… Read More

Hydraulic cutter vs Hammer:Differences and ComparisonContractors/mining engineers have discovered how to increase production and safety.
How does a hydraulic cutterhead compare to hydraulic hammer?
Contractors and Engineers often ask how does a hydraulic cutterhead attachment performs in comparison to a hydraulic hammer?The hydraulic cutterhead attachments are ideally suited for precision application where over breaking, removal of hard material, sound sensitive projects or helping producing reusable material for back-fill on site are common obstacles.
PRECISION CONTROL (IMPROVES PRODUCTION AND SAFETY)With technology evolved from the mining industry, Antraquip’s hydraulic rock and concrete cutting attachments (Cutterheads) are a versatile tool with many uses… Read More
WHAT TYPE OF PRODUCTION CAN I EXPECT FROM A ROCK?CONCRETE GRINDER?Production rates can vary considerably depending on the size and power of the Grinder that is being employed and the strength of the rock/material that is being cut. For instance the variability of production rates depending on rock type/hardness as well as cutter/grinder model can range from 1cu. yd/hr – 200 cu. yds/hr. This illustrates the importance of understanding the main factors that will determine actual production rates.As a general guideline, the largest Grinder can offer over 60cy/ hr. in productions based in a mid-soft rock application.Rock strengths can vary… Read More
