The W240 worm wheel gearboxes are maintenance-free, compact drive units for ventilation and hoisting systems in greenhouses and livestock houses. W240 worm wheel gearboxes are mainly used in indirectly-driven systems, where several W240 worm wheel gearboxes are driven by one motor gearbox. A mobile drive can also be supplied. W240 worm wheel gearboxes feature a self-braking worm gear transmission (i=35). This low-noise transmission ensures that the output shaft is blocked when the drive unit is halted. W240 worm wheel gearboxes are available in a standard version and in a version with continuous worm shaft (W240D). W240 worm wheel gearboxes feature 16-tooth sprocket wheels (1⁄2"x5⁄16") on the input and output shafts and can be fitted on mounting plates on both sides of the worm wheel gearbox. W240 worm wheel gearboxes are finished in graphite-grey powder coating, and are supplied complete with fixing bolts and spring washers. W240 Worm wheel gearboxes: Drive torque up to 240 Nm; Suitable for intermittent operation, operating class s3-30%, duty cycle maximum 25 minutes; Other specifications and colours available on request.
