Product features:
1.Save time.
2. Reduce labor intensity
3. Bearing strength larger (700KN)

1. This product for my company independent development of patent products, sizing size 186, can pass setting up. Applicable to bring pressure homework corollary equipment, its structure than the international similar product, in oil field can be at ease use.

Model qw50a air operated slips internal structure 2) using taper surface sliding cooperate, has self-tightening function. When carvalho tooth and tubing after contact, the tubing press, can drive carvalho body moves down, pressures more calories pre-tighten force is bigger also, hold the more tight, the largest bearing strength can reach 70t.

3. Shell, carvalho body materials were medium-carbon steel forgings, high mechanical strength, carrying capacity, carvalho tooth material is special material, tooth end hard, internal flexibility, suitable for card, hold string no damage.

4. Two carvalho action by linkage mechanism, the movement synchronization, linkage good rigidity.

5. Linkage mechanism, dynamic enough oil cylinder driving, action quick, overall opening-closing only 1 ~ 2 seconds. (if the user requirements, our company also can configure cylinder driving)

6. Greatly alleviated oilfield JingDui employees working strength, improve work efficiency, and ensure the safety operation.
