Trowels and Screeds

 

[1]Flip, switch, sensor shut-off

Walk-behind power trowels are basically simple machines consisting of a handle, engine, ring guard, gearbox and lower-blade unit. However, it’s important to never overlook proper operation of critical safety features, especially the emergency engine shut-off function. Most manufacturers use a centrifugal flip switch or hold-to-run switch to reduce uncontrolled trowel runaway and bring the machine to a stop. These switches can wear over time and require occasional maintenance. A gyroscopic sensor, like in Wacker Neuson’s 36- and 48-inch walk-behind trowels, senses when the operator releases the handle and shuts down the engine, which engages a brake mechanism internal to the gearbox. Whatever type safety system you use, make sure to test its function before operations.
