Manual Swing Handle Operator
Manual Wormgear Operators
The swing handle operator is designed with simplicity in mind that makes it reliable and easy to operate. The swing handle, aka the torsion bar, is made from the highest quality materials. The support plate and handle are made from galvanized steel and the pipe clamp is machined from billet 6061-T6 aluminum. The guiding axel is made of high strength bronze. Padlockable in the open and close position, the handle locks in the upward position. This avoids the handle being buried in the snow.
Available Gear Ratios: RV801 – 80:1, RV402 – 40:1, RV204 – 20:1.
- Simple
- Robust
