Lifting & handling tool

Rocksteady heavy lift tool

The Rocksteady® lift tool is a quick connector for heavy offshore lifting operations

A fail-safe and visually verifiable lock guarantees safe lifting while saving hours of sling handling.

The Rocksteady lift tool represents a step change in lifting operation speed: disconnect and reconnect from payloads in seconds saving hours of rigging up/down for heavy lifts. Rocksteady is optimised for crane hook motion, with wide funnels and generous capture angles, we have proven in testing over 15° installation angles and land at up to 3 metres / second.

Cost-efficient receptacles can be pre-installed to any equipment to be lifted, including hammers, vibro-hammers, transition piece lifting tools, pile lifting tools, containers and baskets.

Rocksteady heavy lift tool uses standard lifting interfaces (shackles, slings), to enable rapid change-over and prevent downtime if your lifting schedule changes. Receptacles can also be integrated in the lifted equipment, to save additional sling lengths and minimising hook height.

The Rocksteady lift tool uses the same battle-tested connection mechanism of all our Rocksteady product lines. The connecting mechanism is inspired by wellhead collet connectors, the load is transferred through machined forged load shoulders produced to the highest offshore quality.

We have engineered the locking mechanism to prevent disconnection while loaded, even with a complete loss of hydraulic or onboard power. Manual override permits easy disconnection even in the event of loss of hydraulic supply. Clear visual indication of lock/unlock status provides a quick reference to all personnel that a lift is safe to proceed.

Rocksteady advantages

  • Cost efficient design with low part count for easy offshore maintenance
  • Low cost “pancake” style receptacle can be easily integrated or machined into lifted equipment
