Abstract

977,626. Lifting platforms. I. TREPEL, and J. SHIRDAN, [trading as MASCHINENTREPEL KOMM. GES.]. Oct. 4, 1961 [April 22, 1961; July 26, 1961; Aug. 9, 1961], No. 35805/61. Heading B8H. [Also in Division G1] A load-elevating platform is guided by at least three pairs of scissor-links and is raised by hydraulic rams acting directly on the scissorlinks or on separate links pivoted to the base. As shown in Fig. 1, three pairs of links 3, 3a are pivoted at 4, 4a to the base frame 1 and platform 2 and are provided with rollers 5, 5a. Two hydraulic rams 7 are pivoted between the base frame and a bar 8 which rigidly connects the links 3, and a pressure gauge 14 is connected to the rams through an electromagnetic valve 13 which is opened on engagement of the platform with a contact 12 and is calibrated to show the weight of a load on the platform. Stops 9 are provided to prevent the operator's feet from being trapped when the platform is lowered. In the embodiment shown in Fig. 3, the platform is guided by four pairs of scissorlinks 15, 16 and is raised by hydraulic rams 20, 20a pivoted between the base frame and links 18, 18a which are pivoted between plates 17 on the base frame and are provided with interengaging toothed quadrants 21, 21a and which support the platform 2 on rollers 19, 19a. Towards the upper limit of travel of the platform, the rollers 19, 19a run on wedge surfaces 22, 22a.
