McKissick HF-1 Hay Fork Pulley Block - Manila Rope - 1-1/4 in - 1 Ton - 4-1/2 in

Product Description

The McKissick HF-1 Hay Fork Pulley Block is a single-sheave block designed specifically for hay fork and hay carrier applications using manila rope in agricultural barn and storage environments. Rated for a 1-ton working load limit, this block is built around a 4-1/2-inch outside diameter sheave supported by a roller bearing, providing smooth, low-friction rope travel during repeated lifting and trolley operations common in hay loft and barn rigging systems. The HF-1 series accommodates manila rope cable up to 1-1/4 inches in diameter.

The hay fork designation indicates this block is purpose-built for use in traditional hay handling systems, where it serves as a fixed or running block in a rope-and-pulley arrangement used to lift and transport hay bales, grapples, and fork loads along a barn track or carrier system. The roller bearing sheave delivers efficient rope travel with minimal friction, reducing operator effort and wear on the manila rope during high-cycle barn operations, and offers improved performance compared to bushing bearing configurations under repeated loading. The block's construction is suited to the demands of agricultural use, where reliable, repeatable performance across a full harvest season is essential.

The HF-1 is a well-established McKissick product in the agricultural and farm rigging market, trusted for its straightforward design and dependable operation in hay loft, barn, and storage facility applications. This roller bearing variant offers enhanced sheave efficiency compared to the bronze bushing version of the same series, making it a preferred choice where reduced rope wear and smoother operation during high-cycle hay handling are priorities.
