The Gray Manufacturing FLJ-400C is a new, manual-operation walking beam forklift jack rated at 4 tons (8,000 lbs / 3,630 kg) capacity, designed specifically for lifting forklifts by engaging the walking beam or fork carriage frame. The low-profile steel chassis slides under forklifts with limited ground clearance, while the hydraulic bottle jack cylinder with a chrome-plated ram provides the vertical lift force; the long-handled pump handle gives the operator the mechanical advantage needed to raise heavy forklifts without air or electric power. The two-position lift pad, clearly labeled on the unit, accommodates different lift points on the forklift undercarriage, and the wheeled rear axle allows repositioning after each pump stroke — the defining feature of the walking beam design. Made in the USA by Gray Manufacturing Company of St. Joseph, Missouri, the FLJ-400C ships complete with the owner's manual and is the industry-standard tool for forklift maintenance shops, fleet service operations, and dealers requiring safe, portable single-technician forklift raising.
