Usually a heavy box, container or pallet with a load attaching to a lifting mechanism using four ropes-slings; lumber, pipe of large diameter it is possible to raise two. If you overwhelm sling loop-the loop, the normal load will rise and it one. Well, if you want to move, say, heavy sheet metal?
On the Leningrad car-building factory of a name of I. E. Egorov, in this case, do just one sling. This became possible thanks to hung on it simple to capture, developed by factory innovators. It is a team of the bracket, in the “beak” which has a toothed eccentric. When the lower sheet through the clamp eccentric “recessed”, and the sheet is free to slip inside. But at the slightest attempt of a reverse movement he “sakasavesa” eccentric in its beak bracket and is held securely therein. Locking device prevent accidental opening of the grip and improves safety.
1 — eyelet for wire rope, 2 — body, 3 — a fixed jaw, 4 — leaf, 5 — eccentric clamp.
When your own size 60X120X320 mm gripper capable of holding a weight of up to 200 kg. Its use for easy transporting of sheet steel in industrial conditions and doubles productivity.
