Logistics Simplified: How the CMS-7 Super Sack Mixer Solves Your Hardest Job Site Challenges Featuring B50G Shotcrete Pump
In the construction and infrastructure industries, the most difficult jobs aren’t always the most technical, they are the ones with the worst logistics. When you are working in a remote area where a ready-mix truck cannot reach, you are often left with two bad options: expensive specialized delivery or the back-breaking labor of hand-busting bags.
The CMS-7 Super Sack Mixer was engineered to solve exactly that. It bridges the gap between manual labor and large-scale ready-mix, giving contractors the power to batch high-quality material anywhere they can take a skid steer.
Case Study: High-Volume Output with the B50G Pump
During our recent Demo Days, we put the CMS-7 to the test by pairing it with a B50G Shotcrete Pump. This was the perfect demonstration of the mixer’s ability to keep up with high-demand equipment.
- The Setup: We used a forklift to load a Spec Mix super sack into the hopper, which emptied in seconds.
- The Feed: Once the operator dialed in the water-to-concrete ratio (which literally took seconds), the CMS-7 provided a steady, continuous flow of material directly into the B50G.
- The Performance: Even with the B50G pumping at a high volume, the CMS-7 maintained the hopper level without breaking a sweat. It proved that you don’t need a massive crew or a fleet of trucks to maintain a professional, high-output application.
The Solution: Hydraulic Power and Portability
The CMS-7 is a universal tool designed to feed pumps, buckets, or forms in environments where traditional equipment fails. The keys to its success are:
- Hydraulic Versatility: It runs entirely off the auxiliary hydraulics of your existing equipment, like a skid steer or loader.
- One-Person Operation: A single operator can manage moving, loading, mixing, and product output, replacing a full “bag-busting” crew.
- Mobile Design: The unit features a compact footprint and a pin-and-sleeve leg system that allows for various heights and easy leveling on uneven terrain.
Built for Any Application
Because the CMS-7 offers a continuous flow of up to 7 cubic yards per hour, it is the logistical “missing link” for contractors working with everything from cellular concrete to specialized mortars and grouts.
