Crane Hook and Sheave Storage Before Installation

A crane hook or sheave may spend weeks in transit or storage before installation. During that time, a damaged bore, corroded contact surface or missing identification record can delay assembly. A receiving and storage routine helps maintenance teams preserve the component and confirm that it matches the intended crane.

Check the Shipment Before Putting It Away

Compare the delivered item with the purchase order and approved drawing. Record the part number, drawing revision and identification markings where provided. Inspect the packaging for impact damage or moisture, then check accessible machined areas for dents, corrosion and damaged protective covers. Keep the inspection record with the component so it can be traced when installation begins.

Protect Sheave Grooves and Mounting Fits

A sheave should be supported securely so it cannot roll or strike another component. Keep its rope groove, bore and mounting faces away from direct contact with floors, chains and other metal parts. Retain the supplier's protective coating and covers unless the installation procedure calls for their removal. If the sheave arrives with bearings or seals fitted, follow the supplier's storage instructions for the complete assembly.

Store Hooks Without Damaging Critical Areas

Use stable supports suited to the hook's size and weight. Avoid resting the hook on its point, threads or other machined connection surfaces. Keep markings legible and protect exposed fits from dirt and moisture. Do not weld, grind or straighten a hook to correct damage found during receiving; set it aside for assessment under the manufacturer's instructions and the site's approved procedure.

Keep Separate Bearings Clean and Packaged

Where bearings are supplied separately, leave them in their original unopened packaging until they are needed for mounting. Store them in a clean, dry area protected from condensation and vibration. Avoid opening a package merely to check the bearing by hand; use its label and accompanying documentation for identification first.

Make a Final Check Before Installation

Before fitting the part, confirm that its identification still matches the approved drawing and that protective materials have kept contact surfaces clean. Recheck for handling damage, corrosion or missing components. If anything is uncertain, hold the part for qualified review rather than relying on its appearance alone. Final inspection and installation should follow the equipment manufacturer's requirements and the site's lifting procedures.
