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.
Liebherr luffing jib cranes deliver high load capacities and outstanding hoist speeds. This enables them to contribute to rapid construction progress. On all HC-L cranes, the intelligent Litronic crane control system helps ensure that the crane is controlled efficiently and safely. The 710 HC-L crane out performs all others in its class. Introducing the latest innovation from Liebherr-Werk Biberach, the 710 HC-L luffing boom crane. Setting new performance standards among comparable luffers in its weight class. Designed on the new A-frame platform, lightning fast load cycles, with strength to match. 1  Up to 141,100 Ibs maximum load. 2  Achieve faster hoist speeds using two hoist drives simultaneously. 3  Redesigned tower measures at 7.9 ft external dimension. 4  All crane parts minimized to 22,000 lbs maximum for easier handling.
