Tannins + Health = Good There is actually a study on the effects of wine and tea tannin and oxidation in the body. In the tests, wine tannin resists oxidation whereas tea tannin did not. In other words, it may be super good for you. You can read the synopsis here.
A jib crane is a type of crane where a horizontal member (jib or boom), supporting a moveable hoist, is fixed to a wall or to a floor-mounted pillar. Jib cranes are used in industrial premises and on military vehicles.ormally a crane with a hinged jib will tend to have its hook also move up and down as the jib moves (or luffs). A level luffing crane is a crane of this common design, but with an extra mechanism to keep the hook level when luffing.
To avoid this, the craneâs entire 55 m boom was raised to its highest angle, bringing the load closer to the crane and minimizing potential swing. The crane is also fitted with a 36 m luffing jib. The 31000âs VPC system minimizes the craneâs footprint and ground preparation by suspending the counterweight in mid-air, rather than using a wheeled counterweight trolley, found on other high-capacity crawler cranes.
