Campbell SAC Screw Adjusted Plate Clamp / #6421000

The Campbell SAC Screw Adjusted Plate Clamp (#6421000) is a manually adjustable plate lifting clamp that uses a screw mechanism to set the jaw opening to match the plate thickness. Unlike cam-actuated clamps, the SAC allows the operator to precisely pre-set the jaw width, providing a secure grip on plates of a specific thickness. Ideal for repetitive lifts of uniform plate stock.

Key Features

• Screw-adjusted jaw allows precise setting for specific plate thicknesses
• Secure mechanical clamping force independent of load weight
• Hardened steel jaw pads protect plate surfaces
• Working load limit and adjustment range clearly marked
• Ideal for repetitive lifts where plate thickness is consistent

Common Applications

• Repetitive lifting of uniform-thickness plate stock
• Production environments with standardized plate sizes
• Steel processing where precise jaw fit is preferred
• Applications where cam-style clamps may not suit the plate surface

Why Campbell?

When you need a tailored fit rather than automatic adjustment, the SAC gives operators full control over jaw width. Perfect for production runs where every plate is the same thickness and a consistent, repeatable grip is essential.

Governing Standards

• ASME B30.9 — slings (web, round, wire rope, chain) inspection and use
• ASME B30.26 — rigging hardware (shackles, eye bolts, links, turnbuckles)
• ASME B30.10 — hooks
• OSHA 1910.184 and 1926.251 — general industry and construction sling safety
• WSTDA WS-2 and RS-1 — web and round sling design

Inspection & Safety

Before every use: visual check for cracks, corrosion, distortion, wear, and illegible markings. Annually (minimum): documented periodic inspection by a trained inspector. Remove from service at first sign of damage. Never repair rigging hardware by welding, heating, or bending.

WARNING: Improper use of rigging can cause death or serious injury. Never exceed the rated Working Load Limit. Apply derating for side-loading, elevated temperature, or chemical exposure. Final application decisions must be made by a Qualified Person per OSHA 1926.32(m).
