What Is a Coil Grab and How Does It Work

A coil grab is a mechanical crane attachment that lifts steel, aluminum, or wire coils by clamping onto the outer or inner diameter, using purely mechanical action with no external power source required.

How a coil grab works

A coil grab hangs from a crane hook and closes around a coil's outer diameter (or, in some designs, its inner diameter) through mechanical linkage — the weight of the coil itself, or a mechanical actuation mechanism, drives the gripping arms into secure contact. Because the mechanism is mechanical rather than powered, there's no hydraulic or electrical system to maintain on the grab itself, which is one of the reasons it's a common choice across steel mills, service centres, and general fabrication shops.

Product variants

Pragya manufactures coil grabs in three configurations: the standard coil grab, which grips the outer diameter; the solid bar grab, built with enhanced grip specifically for solid bar coils; and a motorized coil grab variant that adds electric rotation for positioning the coil after it's been lifted. The choice between these depends on the exact material being handled and whether the operation needs to reorient the coil mid-lift.

Capacity and coil size range

Pragya's coil grabs are rated up to 45 ton and accommodate coil diameters from 1067–1880 mm (42"–74"). They're built in wear-resistant steel construction and proof tested with certification before use, meeting ASME B30.20, the standard for below-the-hook lifting devices. As with any crane attachment, the capacity should be selected for the heaviest coil the operation will ever lift, not an average across the coil mix.

Where coil grabs are used

Coil grabs see use across steel mills and fabrication plants, coil storage and retrieval operations, transport vehicle loading, and service centre operations — essentially anywhere a coil needs to move by crane without floor-level rigging. They're commonly compared against C hooks and coil tongs, which lift coils by different mechanisms: a C hook engages the coil's inner bore, while a coil tong grips the outer diameter using tong-style jaws rather than a grab's clamping mechanism. Our coil grab vs C hook comparison and coil tong selection guide go into each in detail. The right choice among the three generally depends on coil ID/OD range, whether the grip needs external power, and the specific handling environment.

What to check before buying

Beyond capacity and coil diameter range, a coil grab buyer should confirm the grab's construction material and wear resistance (since the gripping surfaces see repeated contact with the coil), whether proof load testing and certification are included, and whether the standard, solid bar, or motorized variant fits the specific coils being handled. A grab sized correctly for tonnage but mismatched to the coil's actual diameter range won't grip securely regardless of its rated capacity. Bring your coil dimensions to our engineering team rather than sizing on tonnage alone.
