- Contains a built-in bronze muffler in the valve housing.
- Gears are designed to withstand continuous running at full load and are
permanently lubricated to provide long life and low maintenance.
- Disc type motor brake releases automatically in hoisting direction and sets as
soon as slight motor shaft rotation in the lowering direction. Also designed to eliminate
