Product Description
Crosby IPU10 & IPU10J Vertical Plate Lifting Clamps
The Crosby IPU10 and IPU10J vertical lifting clamps are designed for the safe lifting, turning, and vertical transfer of steel plate, sheet, and fabricated materials. These heavy-duty plate clamps feature a universal articulating hoisting eye that allows the clamp to align properly under load and accommodate lifting from multiple directions.
Unlike the fixed-eye Crosby IP10 series, the IPU10 uses a hinged lifting shackle that helps reduce side loading during lifting operations. This makes the IPU10 series especially popular for use with multi-leg chain slings, bridles, and applications where lifting angles may vary. The universal lifting eye allows the clamp to rotate and align naturally during lifting and turning operations.
Available in capacities from 0.5 ton through 30 ton, Crosby IPU10 clamps provide full 180-degree turning capability and are individually proof tested to 2 times Working Load Limit with serialized traceability and certification documentation included.

Frequently Asked Questions
What is the difference between the Crosby IPU10 and IP10 lifting clamps?
The Crosby IPU10 features a universal articulating hoisting eye that allows the clamp to align under load and accommodate angled lifting configurations. The Crosby IP10 uses a fixed lifting eye intended primarily for straight vertical lifting applications.
Why would I choose an IPU10 instead of an IP10?
The IPU10 is often preferred when using multi-leg slings, bridles, or lifting setups where the sling angle may vary during lifting. The hinged hoisting eye helps reduce side loading on the clamp and allows greater lifting flexibility.
Can Crosby IPU10 clamps be used with chain sling bridles?
Yes. The articulating hoisting eye makes the IPU10 series ideal for use with chain sling bridles and multi-leg lifting assemblies where the connection angle may not remain perfectly vertical during lifting.
What material hardness can Crosby IPU10 clamps handle?
Standard Crosby IPU10 and IPU10J clamps are rated for materials up to 363 HV10 (approximately 345 HB). For harder materials up to 472 HV10 (450 HB), Crosby offers the IPU10H series designed specifically for higher hardness applications.
What is the Rockwell hardness equivalent for Crosby IPU10 clamps?
The standard IPU10 hardness limit of 363 HV10 is approximately equivalent to 36-37 HRC, while the IPU10H series rating of 472 HV10 is approximately equivalent to 45 HRC. Always verify actual material hardness before lifting.
What is the minimum weight an IPU10 clamp can safely lift?
Most Crosby IPU10 and IPU10J clamps require a minimum load equal to 10% of the clamp's rated Working Load Limit (WLL). The 0.5 ton model may be used down to 5% of rated capacity. Softer materials up to 279 HV10 may also allow 5% minimum loading depending on the model.
Can Crosby IPU10 clamps rotate or turn plate?
Yes. Crosby IPU10 clamps provide full 180-degree turning capability, allowing materials to be lifted from horizontal to vertical and back down as needed during fabrication and material handling operations.
Can IPU10 clamps be used in pairs?
Yes. IPU10 clamps are commonly used in pairs with spreader beams or multi-leg sling assemblies for lifting longer plates and fabricated structures. Ensure each clamp shares the load equally and follows Crosby lifting recommendations.
Are Crosby IPU10 clamps proof tested?
Yes. Every Crosby IPU10 and IPU10J clamp is individually proof tested to 2 times the Working Load Limit and includes certification documentation and serialized traceability.
Can these clamps lift stainless steel?
For stainless steel applications, Crosby recommends the IPU10S series. Stainless-specific clamps help reduce the risk of surface contamination and contact corrosion.
Do Crosby IPU10 clamps require maintenance?
Yes. The gripping teeth, pivot points, springs, lifting eye, and moving components should be inspected regularly for wear and proper function. Crosby maintenance and repair kits are available to help extend clamp service life.
