where can i take used wooden pallets for cash?
Picture the two 'tines' of the fork. Each one has a roller, placed about 3/4 down the length, and another one at the base (where the 'tines' converge). When activated, the hydraulics push a rod connected to the roller's axle. When the operator 'jacks' the handle, the 'forks' are pushed upwards, and the roller stays on the ground.
