Harrington Hoists Inc. introduces the HFPSL Four Point Sack Lifter Beam designed to lift bulk container sacks. The HFPSL is available in 1 and 2 metric ton capacities with outside spreads of 36 and 48 inches.
The HFPSL Four Point Sack Lifter Beam features an X-Style design that provides a natural fit over the top of the bulk container sack and allows for a straight-line connection to lifting slings. Additional features include: a standard Sling Keeper design to improve sling containment during the lift, a machined radius cut into the top inside edge of the bail to ensure a better connection between the saddle of the hook and the upper radius of the bail, smooth edge cross-beams to reduce wear on lifting straps, and can be ordered in stainless steel and low-headroom designs.
The HFPSL is engineered and manufactured to ASME B30.20 & BTH-1 Design Category B Service Class 2 and has a specified fatigue life of 100,001 to 500,000 load cycles. All HFPSL Four Point Sack Lifter Beams are Proof-Tested to 125 percent capacity.
