Flat Hooks, metal | 3,000 to 16,000 lb

The below capacity ranges indicate the working (dynamic) load that each caster will support. A safety factor should be included in your formula to determine your required load rating per caster.

W/(C-1)=R W is total weight needed to move. C is total number of casters required. R is ideal load rating, with safety factor built in. Divide the total load weight by one less caster than you will use to safely determine load rating.

Steel Chain Hooks · Flat Hook · 3,000-16,000 lb

This collection holds Flat Hooks casters with metal wheels, built for heavy equipment, dies, molds, and plant carts that move very heavy loads. Casters in this collection range from 3,000 to 16,000 lb per caster. Metal wheels roll with low effort and handle debris and heat. They are loud and can mark finished floors. Match plate size, bolt pattern, and overall height before you order. Read the listing for the exact wheel size, overall height, and mount shown. Confirm the load rating printed on the title before you order. Measure the old wheel or caster before you buy. Check the floor type and the heaviest load the cart will carry before you choose. Call or email CasterHQ with the part number from the old unit if you need help matching it. Brakes help on ramps. Check the floor first. Many carts run two swivel and two rigid casters for easy steering. Forged steel aisle: forged steel casters. Wheel hub: replacement wheels.
