Abstract
1,029,850. Mobile luffing arm machines; vehicle load platforms. W. H. PAYNE. April 30, 1962 [Feb. 7, 1961], No. 27356/65. Divided out of 1,027,451. Headings B8E and B8H. [Also in Division E1] The load-handling apparatus of the boomtype truckloader described in the parent Specification is provided with a platform or load carrier having hydraulic levelling means such that movement of the members of the apparatus transmits fluid power to or for the operation and control of the actuating means of the levelling means, thus maintaining the platform or carrier level through the range of movements of the load-handling apparatus. A work platform 160 is adjustably mounted at 161 on a lever arm 158 pivoted at 159 to a main framework 157 pivoted at 156 to the jib 9 of the load handling apparatus. Levelling jacks 162, 165 can maintain the platform level in any position of the jibs 7, 9 as indicated. The operations of the levelling jacks 162, 165 may be effected by servo jacks 173, 174 or by a manually operated control valve or by a combination of these controls. In modifications shown, the platform 160 may be replaced by lifting forks or a carrier for cylindrical loads.
