Title: LIFT TRUCK MAST HAVING TUBES AS STRUCTURAL AND/OR HYDRAULIC MEMBERS
Abstract:
Tubular elements (40, 40A, 45, 45A, 50, 50A, 55, 55A, 90, 95, 100, 105, 180, 185, 190, 195, 200, 205, 540, 545, 550, 555, 590, 595, 600, 605, 615, 620, 625, 630, 680, 685, 690, 695, 700, 705, 706) are used to construct the support structure for a mast (5, 505) for a lift truck (270). Hydraulic cylinders may be integrated within the tubular structure (40, 40A, 45, 45A, 50, 50A, 55, 55A, 90, 95, 100, 105, 180, 185, 190, 195, 200, 205, 540, 545, 550, 555, 590, 595, 600, 605, 615, 620, 625, 630, 680, 685, 690, 695, 700, 705, 706). Braces (35, 35A, 60, 65, 65A, 70, 70A, 85, 110, 135, 140, 147, 175, 210, 215, 220, 227, 232, 535, 560, 570, 585, 610, 635, 640, 675, 710, 720) may be included to alter one or more of stiffness, torsional resistance, and bending resistance for such a mast (5, 505).
