The strongest cable drive units on the market!
The NC-650 model is the unit of choice for the world’s largest barns. Able to handle up to 650’ (198 m) of 9/16” (14 mm) cable, one unit can clean two alleys up to 2,550’ (777 m) long.
Maximum flexibility
The Nova-Cable drive unit adapts to all barn configurations. Corner wheels can be positioned as close to the transmission as desired. With the optional riser wheel kit, the drive unit can be mounted anywhere you wish, giving you complete control of layouts. Save space at the end of the barn, requires 2’ (60 cm) less barn length than conventional drive units.
Scraper blades & corner wheels
Valmetal offers a wide choice of blades and accessories for every condition. Blade edges are available in steel, urethane or our new abrasion-resistant rubber. Whether you choose straight (rollback) or V-blades, all wear parts are easy and economical to replace.
Automation
The Scraper-Boss PRO control provides the best animal protection in the business. This user-friendly control is packed with features, able to control other parts of your manure system, and may be operated by phone or tablet using the Valmetal app.
Features
Encoder wheel
Sensors count the revolutions of the gearbox to track the positions of the scraper blades. Setting the start & stop positions needs only a touch on the control, and is accurate to a fraction of an inch.
One moving part
The cable drum is threaded, so as it turns on the 5” (13 cm) diameter threads on the stationary shaft, it automatically aligns itself to keep the cable spooling cleanly in place, while eliminating the need for cable guide shafts and drives.
Low maintenance
The drum hub & shaft are encased in a grease chamber to keep all components clean and lubricated. The Nova-Cable drive has very few moving parts, making maintenance easy.
Cables
Nova-Cable works with all types of cable from 3/8” (10 mm) to 9/16” (14 mm) diameter. Choose steel cables (galvanized or stainless), or braided plastic cables (Dura-Cable or Dyneema), or the heavy-duty stainless & polyester hybrid cable (9/16” (14 mm) only).
Two-stage drive
The two-stage drive protects the gearbox bearings from heavy loads, giving Nova-Cable unmatched pulling power and trouble-free gearbox life. The drive sprocket is positioned to the side of the drum, keeping it far from any manure exposure.
XL gearbox
Many alley scrapers run around the clock, so all models of Nova-Cable drive units are equipped with the proven XL gearbox. This helicoid gearbox operates at 95% efficiency, saving power and delivering long life.
