A further visibility aid in the lower mast heights lies in the use of a lift cylinder of shorter length than the primary lifting members, providing a completely open space between the top of the cylinder and the top cross member when the forks are in the lowered carrying position.
Yale's triplex mast construction also offers a higher f.reelif.t-24 inches. The new desiln is offered in standard overall heights of 59, 71, 83,90 and 96 inches which give maximum fork heights of 108, lM, 180, 19{3 and 210 inches, respectively. Three inch increments between these heights are optional. The lift cylinder is equipped with a return line directly back to the hydraulic tank preventing loss of any fluid which might seep past the cylin- der packing. Another feature is the placement of hoses within the upright struc,ture to allow conveision to attachment handling without rearrange- ment.
