Mack Manufacturing Self-Contained Orange Peel Grab

Mack Manufacturing developed the original five-tine orange peel grab to help scrap handlers and steel processors to hold and retain larger loads more efficiently. Specifically designed for electric overhead cranes moving scrap in steel mills, the OPSISCH-350-5 grapple is a completely self-contained electric drive unit, ready for operation with a large 3.5 yard capacity.

The grapple’s heat-treated alloy steel construction combines light weight for high efficiency and lift capacity with rugged strength, including heat-treated steel pins and shafts sized to ensure maximum service life. All Mack grapples and buckets are fabricated with T1 steel, a heat-treated alloy with twice the structural strength of standard mild steel and able to withstand three times as much pressure before bending. All service components feature recognized national brands, including Mack’s own heavy-duty hydraulic cylinders, custom engineered and manufactured in-house.

Mack recommends these grapples for use on all types of derricks and overhead cranes. These orange peel grabs are available with or without hydraulic rotation in sizes from 1.0 to 12 cubic yards.
