Billet tongs composition

Billet tongs mainly composed of seven parts of the lifting beam, connecting rod, opening and closing institutions, synchronizer clamp arm support plate and jaws.
1 lifting beam
The lifting beam days coupler connected components, rings unload button join, the sling join three structures and lifting lug type connection. Rings unload button connection the hanging axis, so that the force of the spreader improve, also avoid handling billet decoupling phenomenon, reducing the height of the fixture itself, and is conducive to low places. The sling type connection hanging axis, so that the force of the fixture, but the spreader own height large, need to use tall places need to use artificial auxiliary hook hanging hook. Lug type connection hanging shaft, by crane driver directly linked, but the need to make the spreader to lifting operations, and date decentralized hook up without force, so easily lead to the crane hook decoupling.

The connecting rod is the lifting beam and the clamp arm connections.
3. Opening and closing institutions
The manual lift rod in the opening and closing institutions (automatic) LASHING (automatic) single hook (automatic) turn-lock and other forms. The automatic hoist mechanism billet jig automatically for opening and closing mechanism. Its operation does not require any external power source, by fixture of its own gravity to achieve the automatic opening and closing of the clamp. Since the lubrication of the closing mechanism of: must be periodically (2 to 3 days) of lubricating oil (or oil), then several vertical movement, until lubricating completely. Non plus excess grease
