Ufist – ROV Lifting and Handling System

Home / U-System Products & Rental Equipment / Ufist – ROV Lifting and Handling System

The Ufist Lifting and Handling System includes various types of low cost ROV fist, handles, bridles and related attachment accessories. This product range was developed in order to suit various operations and applications, and to include features that permit easy, fast and simple attachment to and / or release from subsea equipment. They also permit several items to be attached to fists at the same time, and thereby allowing them to be used as ‘dual action’ fists. The system includes:

  • Large and small ball fists, and ring fist.
  • Various types of attachment straps for fists.
  • Two parted lifting bridles.
  • Three/four parted lifting bridles.
  • Several types of ROV handles including one that is certified for lifting.
  • Various types of extra / optional parts for fist, handles and bridles.
  • Attachment accessories for fist, handles and bridles.

The Ufist products are available for purchase. The Udeco rental equipment includes Ufist products as applicable.

Pictorial procedures illustrating the use and attachment of Ufist products are available in case of purchase.
