Description
The Crosby HR-1000 Heavy Lift Swivel Hoist Ring with UNC threads is a premium lifting point designed for high-capacity lifting operations across construction, manufacturing, engineering, and industrial environments. Built from high-strength forged alloy steel, the HR-1000 series delivers exceptional durability, reliability, and performance in demanding lifting conditions.
The hoist ring features a forged bail construction, providing enhanced strength and toughness compared with conventional lifting rings. This robust design improves resistance to wear and impact, making the HR-1000 suitable for harsh field conditions where lifting equipment may be exposed to heavy use.
A key advantage of the HR-1000 design is its larger bail opening, allowing for easier connection of hooks, shackles, and lifting slings. This improves flexibility when configuring lifting assemblies and helps reduce rigging complications in confined or complex lifting situations.
The ring provides 360� swivel rotation and 180� pivot action, allowing the lifting point to automatically align with the direction of the load. This alignment reduces the risk of side loading and helps maintain the integrity of the lifting system during operation.
Each hoist ring includes raised lettering displaying the Crosby name or �CG� and a Product Identification Code (PIC), ensuring full material traceability and quality assurance. The top washer is permanently stamped with the working load limit and recommended torque value, allowing installers to quickly verify the correct tightening specification during installation.
For quick identification, the washer is colour coded red to indicate UNC thread models, while metric versions of the HR-1000 series use a silver washer. Every unit is individually proof tested to 2.5 times the working load limit, ensuring consistent safety and performance across the entire product range.
The HR-1000 UNC hoist rings utilise alloy socket head cap screws manufactured to ASTM A574, ensuring high tensile strength and reliable fastening performance in demanding lifting applications.
The HR-1000 UNC series is available in a wide range of bolt sizes and configurations, with working load limits ranging from 0.36 tonnes up to 10.89 tonnes, allowing engineers and lifting professionals to select the correct lifting point for a wide variety of load requirements.
Designed for reliability, safety, and long service life, the Crosby HR-1000 UNC swivel hoist ring is a trusted lifting solution used across heavy industry worldwide.
Safety & User Instructions
