The C.U.B.E. Passes Some Tough Testing!
Even though the components used in the new C.U.B.E. have been in rental duty for over 15-years, we wanted to put this equipment to some rigorous testing. There are units being field tested in California and Oregon. These won’t look as pretty as your C.U.B.E., but we told these users to work them hard and give us good feedback…Keep checking our website as we update the projects that use the C.U.B.E.
Field Test #1: Indoor Roping Arena Column Supports.
Total yards to be produced by the C.U.B.E. = 98 yards
The reason for the use of the C.U.B.E. was to reduce the cost of ready-mix at this remote site. The contractor did the excavating and forming with four men and intended on using all four for the concrete mixing and distribution portion of the project.
As it turned out, he only needed three men for the ready-mix work. He used two
skid steers and one backhoe for raw material feeding and concrete placement. This allowed him to keep a continual flow of duties going all day. On the first portion of the project, the crew mixed and placed 48-yards in a day and a half of work.
The contractor reports;
“The C.U.B.E. really surprised us on how it just
kept cranking out the material for us. We had tractors going every which way and the C.U.B.E. never slowed us down”.
Estimated Cost Savings: $4,100.
Field Test #2:
Total yards = 45 yards in 5-yard pours
The five-yard pours where required so that ranch equipment could be moved between sections and then moved onto the cured concrete. The Project spanned three weeks between other work projects.
“The C.U.B.E. worked great for my needs. I could only pour a few yards before moving equipment between the individual stalls. A transit-mix truck would have been tough to schedule and the C.U.B.E. let me mix when I needed it”.
The farm owner used a single loader to fill the drum and for concrete placement. His wife, son, and father worked as his mixing crew.
Estimated Cost Savings: $2,475.
Field Test #3:
Total Project = 98 yards
The Teck Cominco Mine in Northern Washington needed several concrete slabs poured approximately 7.5 miles underground. They tried a contractor mixer and 80# pre-mixed bags of concrete. But with about 100 yards to pour, it became apparent that they would never make their deadlines and would wear-out several employees. They contracted with a site-mix concrete company to solve the problem. And the solution was a combination of the C.U.B.E. and pre-mixed concrete in super sacks. Super sacks of the dry mix were delivered to the C.U.B.E. deep in the mine.
“It saved us a lot of hours over our previous mixing method… It saved us so many manpower hours!”
The C.U.B.E. conveyor was removed so that they could load super sacks and they ordered the optional diesel engine. The crew used a large Gradall to move the C.U.B.E. from the material loading area out over the forms to pour the 13-yards per slab. Using the super sacks allowed them to get the specification mix down to a yard every six minutes.
“By utilizing the C.U.B.E. the bid was completed successfully and the job completed quickly”.
The C.U.B.E. was moved down into the mine in the bed of a one-ton long-bed pick-up. Because the C.U.B.E. is only 4 feet wide it easily slips between the wheel wells of the truck. With the tailgate down and proper safety marking, the unit can be transported hundreds of miles this way. Unloading the truck was accomplished by forking or hoisting from the top rails or the lifting corners.
“ The C.U.B.E. worked just fine. It is a good size for working underground and we mixed 98 yards without any breakdowns!”
By comparison, it took 7 hours to pour 6 yards with the contractor mixer using 80# bags. Using a small contractor mixer left no time in the day to set forms and rebar for the next pour, wasting an extra day. Using the C.U.B.E. allowed for more than twice the volume of ready-mix to be poured in a shift with enough time left over to do the form sets and steel for the next slab!
Estimated Cost Savings: $11,600
Field Test #4: Resort Construction in the Bahamas
A contractor building a resort on a remote island had a problem producing concrete for footings and grouting block. No ready-mix availability meant using a 1/3 yard portable mixer and losing valuable time.
In addition, he could not get the consistency concrete strength that was demanded for the project. Using the C.U.B.E. he can produce over 15 yards a day and has completed cylinder tests to find a consistent 3800 PSI in 8-days.
“The only way we can get concrete on this small island is by mixing it by a smaller machine. I get 15 yards per day with the C.U.B.E…. I could never do that with a 1/3 yard Machine”.
His mix design includes 9 bags of Portland cement, two tractor buckets of gravel, three tractor buckets of sand and 35-40 gallons of water.
