Order pickers are lift trucks that operate in a narrow 5′ aisle. They allow the forklift operator to go up in the carriage of the lift truck and pick orders from the rack. Order pickers have forks that hold a wood pallet. Order pickers operate in a narrow aisle and run on a wire guidance system embeded in the concrete floor. Operators of order pickers must always wear Osha approved safety harnesses and lanyards that are secured to the lift truck at all times.  Warehouse Rack & Shelf LLC offers a full line of material handling products.
