We sent a CB Electric Excavator ( CBEE ) with hammer and two CB Electric Tracked Haulers (CBETH) to a project at a Gold’s Gym remodel where the general contractor was to excavate and install a swimming pool in the adjacent space in a strip mall outside DC .
The pool contractor started digging with a Bobcat skid steer and mini-excavator with exhaust scrubbers until the property owner was called and all excavation was stopped cold. The general contractor was about to be forced to do the digging by hand which they were not in a big hurry to do.
They called us to discuss our CBETHs for hauling out the hand excavated fill. The project manager was trying to retain a Brokk 180 for the digging and our CBETH for hauling out. We talked for a little while and I asked how they were going to load the haulers.
After he mentioned the 180 I told him about a 180 owner ,who in a caption for a Youtube video ,stated that the Brokk although it did not dig well , it beat a shovel . CLICK HERE TO SEE FOR YOURSELF. Press “more info” in the description area underneath the user name.
I told him about the CBEE and went over some of our web videos and he decided to go with our methods ,since our electric excavators solved all of his excavation problems at one time.
Let’s face it, environmental restrictions are only going to get more strict in 2010. An electric powered mini excavator may be a great alternative to costly manual labor on a fume restricted project. The following contractor thought so.
A plumbing contractor used our CBEE2 in a pharmaceutical plant to dig out an acid drain . The plumbing contractor had rented a CBEE for the project but after digging 5 feet for a pipe that the facilities people said would be found at 4 feet, they needed more dig depth.
Enter the CBEE2! A larger electric mini excavator with over 9 feet of dig depth. Needless to say, that phase of the project was taken care of easily . The CBEE2 availability for rentals is limited at this time so please ask early if you think that it is required for your fume sensitive project.
New addition to a line of electric excavators
We are proud to announce the release of the CBEE 2. It is our second electric excavator to officially allow us to say that CB Electric Excavators is the world’s first line of electric powered excavators! Be on the look out for photos and videos. A sneak peek below.
Happy New Year.
Welcome to the future! It has been in the works for awhile last year, but we have finally completed our second CB Electric Excavator. It is a step up in size and power. It is great where spaces are not so confined, has over a 9 foot dig depth and packs a powerful punch with its hammer. Now you meet the needs of your clients’ fume restrictions in food plants, hospitals, schools, labs etc, while still staying productive. Stay tuned for more information soon.
Do us a favor…share this with someone!
Check out this video. This video post was quite a surprise for us! We were not expecting this, however, we now know why the general contractor was not at first excited about seeing our equipment show up on his job site. But thankfully the mechanical contractor found us online and saw video of the CB Electric Excavator that more than justified his decision. As you will see here, the general is way more than happy! After the video read the rest of the story below. “Why the general contractor didn’t want to see us on his job site.”
The general thought that we were a “toy” replacing the other “toy” that had failed on his job site earlier. I would not be excited either, if I thought you were replacing one unproductive piece of equipment with another unproductive piece. That’s why we started recording live project video, so you can see there is a difference.
Ahh, must I remind you all. We are contractors, that developed this equipment for contractors. We use the CB Electric Excavator ourselves.
**If you haven’t seen the video on the right side of your screen yet, make sure you check it out.**
These questions have been answered within another post, but sometimes it gets overlooked. So it has been decided to give it a brief entry of its own.
1. “You put your Brokk 90 up for sale huh?”
1. Yes, we put our Brokk 90 up for sale.
2. We not only perform interior demolition, but we do a lot of interior excavation as well. As you can see from this video post, many Brokk users will admit that it is not the best machine for digging. But it does beat digging by hand when you can’t have fumes on your project. We also felt the same.
The Brokk was great for demolition, especially high reach demolition. However, we realized that most of our projects did not require remote control or high reach.
The Brokk has a longer learning curve involved than most equipment and staying on guys to do proper maintenance was costly.
This is what led to the development of the CB Electric Excavator. We decided to develop it so that it will run the same hammer as the Brokk 90 for demolition.
So if some of the above words relate to your situation, then give us a call. Because at 1/3 of the price it is a better option for many.
But if you do need remote control for safety and a 13 foot high reach, then we have no problem telling you to check out the Brokk 90.
“Brokk 180 with showel digging conrete slabs that have been hammered loose from the floor. If you look closely you will see the metal slabs that were to be removed later. This machine is not ideal for digging, but beats a hand showel 10-0 =D no exhaust and no sweat ;D”
Go to the youtube page for this video and look at the description area yourself if you need to http://www.youtube.com/watch?v=_tSfSA3tSpc.
This chart is a comparison of the some of most important features on these 3 electric powered machines. All data taken from manufacturers published materials where available.
* Please note that the Brokk 90 is remote control and is designed for high reach. So if most of your work requires remote control and breaking over 8 feet high, then the Brokk is a good option for you.
**The previous statement was written to prevent the emails to us about an “unfair” comparison or our “lack of knowledge” about the Brokk. We know all about the Brokk. It’s a good machine. We owned and operated a Brokk 90.**
We just found that most of our indoor contracting jobs did require fume free, but didn’t require remote control or a vertical reach of 13 feet high. That’s what lead to the birth of the CB Electric Excavator. And for about 1/3 of the price of a Brokk 90, a lot of other contractors understand what we mean.

A couple of years ago a dentist called us to look at an interior sawing job to correct some ”oops’s” on an inaccessible basement wall that had recently been poured . We did not end up doing the job ,but we were told a disturbing story by the homeowner. It seems as though when the “oops” happened ,the concrete contractor , a normally reputable company decided to bring in a gas powered quick cut saw to make the needed cuts . The crew began their cutting and everything was going well until the kids upstairs started getting sleepy. The contractor for some reason did not warn the dentists wife and three small children upstairs, of the carbon monoxide risks associated with fossil fuel use indoors. The children as well as their mother had to be transported by ambulance to the hospital and placed in hyperbaric chambers overnight . That was a very expensive mental lapse for that contractor that could have yielded catastophic results.
August 8, 2001 25 people were rushed to local hospitals for treatment after being subjected to exhaust fumes from a concrete saw operated by a plumbing contractor at Kenwood Towne Center in Cincinnati , Ohio. Many of the affected shoppers had to spend the night in hyperbaric chambers to have their systems cleared out. Can you imagine the cost of that treatment and ambulance rides for 25 people ? Some had to be transported to Wright-Patterson Air Force Base 60 miles away for treatment. Can you imagine the legal liability ? Can you imagine what the outcome could have been ? Do you realize how easily this could have all been prevented ? Was this carelessness or was this negligence ?
We are using this as a lead in to a topic that I don’t hear discussed often enough… fumes generated during indoor sawing and excavating . For some reason sawing professionals will go in buildings and use gas, LPG or diesel powered saws , as if they don’t generate carbon monoxide and are perfectly safe, not true. When you use any equipment that burns fossil fuels of any type indoors you are putting your crews and everyone else in danger. Yeah I know a lot of what we do as contractors is fraught with risk, but some risks are just stupid. Contractors and facility managers that continue to allow this practice are being at best remiss in their duties and at worst bordering on negligence .
Just recently we were talking to a superintendent of a large hospital remodel ,about the use of our electric powered equipment on his project he at one point looked at me and said “scrubbers don’t work nobody likes them” (nobody- meaning hospital staff) Using scrubbers you are able to remove some of the noxious smells , but not all of them. Face it if they smell anything at all , somebody’s gonna call .Why take the chance? You’ll never hear any one say “take the diesel units inside , they’ll get used to the smell! Not now nor ever again.
Fume-free electric powered equipment is the way to go and we know that our current and future offerings will help you thrive in these trying times.
Catch the wave early and ride it for a long time. Call us now and let us show you how.
We received a call recently from a concrete cutter who was interested in our CB Electric Excavator as well as our CB Electric Tracked Haulers. As we were discussing different aspects of the business and his operation he mentioned that all of his saw rigs were equipped with 480 3 phase generators and water tanks. I asked him what size diesel or gas saws that he had in addition to his electric saws ? His response took me by surprise , yet did not really surprise me. What I mean by that is that the efficiency of electric motors is well documented, some of the most powerful machines on earth are electric powered, but somehow overlooked – guess they’re just not sexy enough . He said that all he sawed with were electric powered saws.He stated that he was not interested in gas or diesel powered saws period! I suppose that we in the construction industry have a lot of “Tim the Toolman” in us and we gotta have the smoke and noise of ponies at our disposal to feel like we’re “Gittin’ er done” .
This young man who shall remain nameless , pleasantly surprised me with his clarity of thought and common sense . He did a lot of indoor sawing where electric or hydraulic was required for air quality and safety reasons. He could saw inside as well as outside with electric saws , not so with diesel or gas or propane. Why spend the money on equipment that you can only utilize on some of your jobs ? Now, before you guys say “thats the case with a lot of equipment ” I want to point out that he being a two rig operator, this made a great deal of sense to me , and obviously to him. He or his driver could leave the shop in the a.m , and not have to waste time and money backtracking to get another saw. They could use the electric saws outdoors quite nicely. The time lost by using a lower horsepower electric saw would easily be offset by the savings realized by not having to purchase and maintain a gas or diesel saw.
Part 2 of this series coming soon.
