GROUND RELEASE SHACKLES

The MÜLLER SSZ Ground Release Shackle is a specialized lifting accessory designed to enable safe and efficient connection and release of sheet piles, tubular piles, and other foundation elements during lifting and positioning operations. Engineered for durability and ease of use, the SSZ shackle allows operators to remotely release the lifting connection once the pile has been positioned or installed, eliminating the need for personnel to access hazardous areas.

Manufactured with high-strength steel components and designed specifically for demanding foundation construction environments, the SSZ system provides reliable lifting performance while significantly improving jobsite safety and operational efficiency.

The shackle is particularly well suited for applications involving vibratory pile driving operations, where piles must be lifted, aligned, and released quickly without manual intervention near suspended loads.
