Application: Horizontal lifting of steel plate.

The high -quality  metal alloy steel precision forging ,plate chrome .

Loading range: 0 - 5ton.

One piece of clamp is used for the testing, and 2 pieces or4 pieces are recommended for lifting operation, balance beam is needed for horizontal  lifting.          

The loaded object shall not touch anything when operating. over loading is prohibited.                                           

Tested load is 2  times of working load.minimum breaking stength ≥5 times of  working  load .

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.
