BALL OVHL SWVL TOP 7TON SWVL ALY STL

Product Description

The McKissick UB-500E is a heavy-duty top swivel overhaul ball designed for utility crane and hoisting applications where a reliable, free-swiveling connection between the load block and hook is required. Constructed with a steel alloy body and swivel attachment, the UB-500E is built to withstand the demanding conditions of industrial lifting, oilfield, construction, and utility operations. The swivel design allows the load to rotate freely without twisting the hoist line, reducing rope torque and extending wire rope service life.

The UB-500E features a top swivel attachment that connects directly to the crane hook or block, providing a secure and articulating connection point rated for 7 Ton working load. The steel alloy construction delivers high strength-to-weight performance while maintaining durability in field conditions. The overhaul ball provides the necessary weight to return the hoist line and block to the lower position under gravity after the load is released, a critical function in single-line and utility crane configurations.

McKissick's UB-500E series is engineered for compatibility with standard utility crane rigging configurations and is suitable for use in construction, utility line work, oilfield service, and general industrial hoisting. The swivel attachment minimizes line twist accumulation during repeated lifts, making it well suited for high-cycle operations where rope management and equipment longevity are priorities.
