McKissick UB-500S Overhaul Ball - Top Swivel - 10 Ton - Alloy Steel

Product Description

The McKissick UB-500S is a 10 Ton capacity utility overhaul ball constructed from steel alloy, designed for crane and rigging applications where a top swivel attachment is required at mid-to-high capacity ratings. Overhaul balls provide the essential dead weight needed below a crane hook block to ensure the block travels downward reliably under its own weight when the load line is slackened. The swivel attachment on the UB-500S allows free rotation of the load line connection, reducing line twist and improving operational efficiency during repeated lifting cycles.

The UB-500S utility series is built for demanding crane service across construction, industrial, and oilfield environments. The steel alloy construction provides the strength and durability necessary to withstand the stresses of repeated heavy-duty lifting cycles at this capacity level. The swivel top attachment provides a secure and rotating connection point to the crane hook or block, while the ball body supplies the necessary dead weight to overhaul the block, making this configuration well suited to operations where both capacity and line twist management are priorities.

McKissick is a well-established manufacturer of crane and rigging hardware with a long history of field-proven performance in heavy industry. The UB-500S series spans multiple capacity ratings, with this 10 Ton model occupying a mid-to-upper range position within the lineup while maintaining the same reliable steel alloy construction standards as the broader UB-500S series. Always confirm that the overhaul ball's rated capacity is appropriate for the crane and rigging configuration in use, and inspect the swivel and all attachment hardware for wear, deformation, or damage prior to each lift.
