Lifting Gear Hire (LGH) in the US has added overhaul balls to its inventory of lifting, rigging, pulling and jacking equipment.
These are heavy steel balls that are used to provide ballast on the hook end of a crane hoist rope. Overhaul balls, also called headache balls, supply the downhaul weight that’s needed to counter bearing friction and winch-to-boom line weight.
Spilt overhaul balls are made up of two cast iron halves, which clamp to the line with bolts.
Overhaul balls are available for rental from LGH’s warehouses and manufactured by Crosby in two diameters – 7.12 and 9.19 inches (180 and 230 mm) or in weights of 50 and 100 pounds (22.7 and 45.4 kg) respectively.
They’re also offered by Gunnebo Johnson and available in 9.5 and 11.25in (240 and 285 mm) or in weights of 89 and 154 lb (40 and 70 kg) respectively.
