SPEAR
The SPEAR (Self Positioning Engage And Release) is a hands free auto locking hook. The SPEAR is attached to the crane hook and will automatically lock and lift a load connected to the Catcher. When landed, the SPEAR will disengage from the Catcher and release the load.
2Te SPEAR & Catcher
This short demo SPEAR was used with a catcher cast into a concrete block.
25Te SPEAR & Catcher
The 60Te precast block above is for a subsea application. Catchers are cast into the block at 4 corners, and the 4 matching SPEARs are attached to a lifting frame.
150Te SPEAR & Catcher
Our largest SPEAR and Catcher to date is a system that uses the SPEAR to locate a ‘sectored flange’ into the catcher, capable of lifting up to 150Te.
