1873-G3 Gripper Chain
1873-G3 carries a projecting, divided contact profile above the chain base. Its attachment geometry makes the product's shape and contact position central to the gripping arrangement.

Check Contact Depth Before Setting the Gap
The product should engage the intended part of the profile throughout its size range.
Contact Through a Divided Profile
The G3 attachment separates its contact into projecting features. The point at which a product enters that profile affects engagement depth and the space needed beside the chain.
A gripping arrangement should be checked with the actual product contour. A rounded container may engage the profile differently from a flat sidewall. The product's resistance to compression matters when setting opposed chains.

Review the Contact Profile and Return Space
Compare the profile with a product section at its smallest and largest sizes. Establish the contact gap, engagement height and release point.
Use the actual chain and support drawing to confirm the end turn and reverse bend. Projecting contact elements need clearance beyond the lower chain's envelope.
Gripping a Product Along Its Side
A G3 contact arrangement is relevant where a product needs side support during a handling transition. Its divided profile presents discrete contact features that must be positioned against the useful part of the product wall.
The approach guides should establish product position before full contact develops. At release, receiving support must be available as the projecting elements move away from the product.
