Our heavy duty commercial grade pallet forks are 5500lb rated American Made forks, with a heavy duty walk-through chassis. We build our carriage with  1 ¼”x3” slider bars; thinner bars bend and twist, and cause binding when trying to move the forks, not ours! The top screen is ¼” material for strength, and has a walk-through design to allow easy cab door entry and exit. Standard size is 4’ wide carriage with 48” forks, we also offer 5 and 6’ wide carriages as well as 5’ and 6’ long forks. The forks are mounted on upper and lower slider bars, and do not swing away like some, giving you the ability to put some downward force on the forks if you need to.
