500KG CRANE PULLEY (VEH24997 )

This heavy-duty steel U-groove/track pulley is used in portable mini construction cranes and material-handling hoist systems.

Visual Identification & Breakdown

- Heavy-Duty Construction: Features a hardened bearing steel outer ring. This metal configuration prevents grooving or friction-shearing caused by constant contact with high-tension steel wire ropes.

- Integrated Dual-Sealed Bearings: The central hub houses an embedded deep-groove ball bearing protected by a rubber or metal shield. This internal configuration handles high radial loads and prevents dirt, concrete dust, and debris from seizing the internal rotation mechanics during field operation.

- U-Shaped Cable Guide Profile: The deep-set radius groove ensures standard 6mm to 8mm wire ropes seat centered without slipping off track or grinding against the side walls of the crane boom bracket.
