Solution Summary: Ride-on Raking Machine
A ride-on raking machine is an engineering control that can reduce the risk of musculoskeletal disorders from forceful exertions and awkward postures from spreading with manual rakes. It is a drivable unit designed to spread concrete evenly while covering more area in a shorter amount of time. These vehicles are equipped with a seat and handles, or a joystick, for easy maneuvering.
Raking is a step in the process of installing concrete. After the concrete is poured, rakes are used to spread the concrete evenly to the desired site before screeding and other finishing processes can take place. Raking is typically done manually, but a ride-on raking machine automates the process.
The operator stands at the back of the PowerRake® and uses joystick controls to move the hydraulic powered rake. The PowerRake® easily spreads wet concrete as it is poured from the truck.

Stressful hand and wrist activity can cause musculoskeletal disorders (MSDs) such as muscle strains; tendonitis, which is inflammation of elbow and wrist tendons; or carpal tunnel syndrome, which is compression of a wrist nerve, resulting in finger numbness and loss of hand strength. The ride-on raking machine reduces stressful hand and wrist activity by minimizing the need for workers to complete raking tasks manually.
Stooped postures can cause low back disorders, such as muscle strain or a disc herniation (“slipped disc”), which is bulging of disc material possibly pressing on the spinal cord or nerves that go into the leg. The ride-on raking machine reduces stooped postures by minimizing the need for workers to complete raking tasks manually.
