短鱼顶卡瓦打捞筒

Series 70 Short Catch Overshot

  普通卡瓦打捞筒要求一定的打捞范围和最小的引入长度，不满足规定要求则无法实现打捞。当鱼顶在接箍以上仅有很小一段长度，这类落物普通型打捞筒无能为力，短鱼顶打捞筒就能实现这一打捞条件。大大缩短了落鱼允许被打捞外径的长度。

The MZS Series 70 Short CatchOvershot is an external fishing tool designed to retrieve tubular fish when thetop of the fish is too short to be engaged with other overshot. The GrappleControl is positioned above the Basket Grapple rather than below it to allowthe Basket Grapple to occupy the lowest position in the Bowl. This enables theovershot to firmly engage and retrieve a very short fish.
