Crane Fork Frame with Backstop and Brick Tines (set of 2) are spring loaded to keep forks level when empty and maintain payload center of gravity to keep load level. Spring helps to return trolley to empty position when load is released. Design features include king post adjusts for load heights from 48" to 68", 40" wide backstop helps stabilize load, and forks spread up to 40" (out to out). Built-in handles on vertical post provide convenient grip for guiding forks into load. All forks are forged and tapered. The brick tines are especially adapted for use with banded brick, but can be used with other materials. The 1.5" thick by 3" wide forks make it easy to get into the small openings in the brick package. The 39" length keeps the forks from extending beyond one standard 40" brick package. Specs: tines 1.5" x 3" x 39"; capacity 4,500 lbs.
