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.
As one of the more helpful forklift extensions available today, the forklift jib typically comes in either a telescoping or a pivoting design. With both types, the body of the jib fits neatly over and around the two forks or blades of the lift. The telescoping jib makes it possible to leverage the weight of the lift with the heaviness of the object that needs to be transported, as well as making it easier to keep the object a safe distance from the lift itself.
