Concrete Block plants typically rely on one or two highly sophisticated block making machines for their production. If one part of the machine fails, it results in extremely high downtime cost. Consequently, block plants require reliable parts and components in order to stay competitive in the industry. In the 1970’s, Force Control originally designed and manufactured the Posidyne oil shear clutch brakes for the largest block machine OEMs. These units have been running successfully on many machines for 50 years worldwide and Force Control will continue to service the industry with a full line of clutch brakes and motor brakes. You can rely on Force Control products to provide years of trouble free operation with no maintenance and reduced downtime.
How Concrete Block Machines Work
Concrete block plants depend on a few critical pieces of equipment. Skip Hoists carry and feed aggregate and bonding agents into the block machine. The block machine forms concrete blocks through vibration and conveyors move blocks through the plant for processing (e.g. Kiln/oven). Many systems include vibration motors to settle the aggregate mix evenly in molds. Every component has to work together precisely, and every movement needs control. A brake motor plays a central role here, stopping heavy equipment when necessary and preventing jams, misalignment, or product damage.
Why Brakes Matter
Block machines operate under heavy loads and constant stress. A sudden stop can damage equipment, but without quick braking, blocks can shift, conveyors can misfeed, and machines can wear faster. Electromagnetic brakes give you reliable stopping power. They respond immediately and handle repeated starts and stops without overheating. They also protect operators by keeping equipment under control, even in high-speed or high-load conditions. Whether it’s a block machine, a conveyor, or an elevator, the right brake keeps everything running safely and efficiently.
Force Control’s Solutions
Force Control Industries has been producing reliable clutch and brake units for decades. Our Posidyne® clutch brake units are engineered for the demands of concrete block production. Electric motor brakes integrate seamlessly into block machines and conveyors, providing smooth operation and quick stopping. Electromagnetic brakes respond instantly, ensuring heavy motors don’t overrun or damage conveyor and elevator equipment. Using the right brake motor helps maintain alignment and reduce wear, keeping your plant running longer without costly repairs.
Our units are used in mold vibration systems, loading and unloading conveyors, and block presses worldwide. They handle heavy cycles, resist wear, and deliver consistent performance. The combination of electric motor brakes and electromagnetic brakes ensures your machines stop precisely when needed, protecting both your products and your team.
Maintenance and Longevity
A well-maintained brake system keeps a plant running. Clean, dry air and correct alignment are simple steps that prevent premature wear. Using approved lubricants in units that require them helps extend service life. A brake motor that is properly installed and maintained can last for years, saving time and reducing replacement costs. Keeping brakes and motors in good condition prevents downtime and keeps your production line moving efficiently.
Support for OEMs and Manufacturers
Force Control works with machine manufacturers and plant engineers to match clutch and brake systems to their machinery. Whether you need a custom fit or a replacement for existing equipment, we provide the technical expertise to select the right electric motor brake or electromagnetic brake. Our goal is straightforward: reliable operation, reduced downtime, and longer equipment life.

Air Supply
Dry and clean air supply and properly set air pressures are the most critical factors for your Posidyne’s lifespan. We recommend using high quality regulators and gauges to extend the life of your Posidyne.
Posidyne models have top and bottom ports. We recommend using the bottom ports which adds an extra layer of defense against debris that could contaminate the unit.
Installation Tips
Proper installation requires the feet to be shimmed so that the housings are not twisted when the unit is bolted down.
Belt drives need to be properly aligned and tensioned. Routinely inspect sheaves and belts for wear as low or high belt tension could damage the Posiydne.
Lubrication
Force Control’s Posidynes use Mobil ATF Type F transmission fluid. We strongly recommend using this lubricant as it results in the longest service life compared to other fluids. If you cannot find Mobil ATF Type F, use one of the following approved fluids:
- Havoline ATF Type F
- Chevron ATF Type F
- Kendall ATF Type F
