1.用途：適用于鋼板豎直吊裝。
2.采用合金鋼精密鍛造。
3.載荷范圍：0-8噸。
4.以單只試驗為額定載荷，吊裝作業(yè)時單只或兩只配套使用。
5.只能同時吊裝一塊鋼板，嚴禁層疊吊裝。起吊時必須將拉環(huán)手柄向上，以使彈簧拉緊，卸荷時拉環(huán)手柄向下，彈簧放松后鉗子和鋼板才能分離。
6.吊裝過程中不得碰撞被吊物，嚴禁超載使用。
7.試驗載荷=額定載荷×2，破斷載荷≥工作載荷×5。
8.帶彈簧鎖無作業(yè)狀態(tài)下，鎖具自然加緊，吊上物體夾力呈比例增加。
9.強韌耐久，易操 作。
1.Application：vertical lifting of steel plate.
2.The high-quality metal alloy steel precision forging.
3.Loading range：0-8ton.
4.One piece of clamps is used for the testing，and 1 pieces or 2 pieces are recommended for lifting operation.
5.Multi plates can not be lifted. Only lift one piece of clamp one piece of clamp one time. Up the lock lever to tighten lock spring when it under loading.Down the lock lever to loose lock spring，when you could unload.
6.Tested load is 2 times of working load. Minimum breaking strength ≥5 times of working load.
7.With lock spring during the clamp non-work condition，locking device going in nature step-up，put the object in the clamp，the strength becomes the proportion enhancement.
