McKissick HF-4 Hay Fork Pulley Block - 1/2 in - 1 Ton - 4-1/2 in - Roller Bearing

Description du produit

The McKissick Series HF-4 Hay Fork Pulley Block is a single-sheave block purpose-built for hay fork and hay trolley rigging systems used in agricultural barn and loft applications. Rated to a 1-ton working load capacity and compatible with wire rope up to 1/2 inch in diameter, the HF-4 is designed for the repetitive lifting and load-transfer cycles typical of hay handling operations. The 4-1/2-inch sheave outside diameter is appropriately sized for the lighter wire rope diameters commonly used in smaller hay fork tackle systems, providing a suitable bend radius for reliable rope performance over extended use.

Equipped with a roller bearing assembly, the HF-4 reduces friction during operation, contributing to smoother rope travel and reduced wear on both the sheave and wire rope through repeated use cycles. The hay fork pulley block configuration is purpose-built for integration into traditional barn rigging setups, where the block redirects the wire rope lead from the hay fork carrier along the track and down to the pulling source, whether a tractor, vehicle, or stationary power unit.

McKissick has a long history of manufacturing blocks for both industrial and agricultural applications, and the HF-4 reflects that heritage with a straightforward, durable design suited to the demands of farm and barn environments. As with all rigging components, proper matching of rope diameter, hook or attachment hardware, and working load ratings across all elements of the tackle system is essential for safe and effective hay fork operation.
