  • Barrel grasping device for automatically clamping onto the pole of a barrel trolley
    Patent number: 5405235
    Abstract: A barrel grasping device with upper and lower jaws pivoted to a double yoke surrounding the pole of a barrel trolley. An auxiliary yoke imprisoning a clamping plate is slidingly mounted on the pole above a double yoke and is connected to the latter by a compression spring. A connecting rod is pivoted at one end to the double yoke and at its intermediate portion to a lever having one extremity pivoted to the auxiliary yoke around an off-set axis and engaging a clamping plate. The weight of the barrel transmitted by the jaws to the double yoke automatically pulls the connecting rod, causing the lever to pivot and push the clamping plate against the pole, thus clamping the device along the pole of the barrel trolley.

  • Fork-lift truck with synchronized variable travelling and lifting surfaces
    Patent number: 4502568
    Abstract: The fork-lift truck comprises two elements independent of each other, each element comprising a vertical mast integral with a horizontal side frame provided with wheels and integral with two parallel cross pieces disposed at different heights, the parallel cross pieces of one element being designed to slide inside the corresponding cross pieces of the other element thus allowing the adaptation of the width of the truck to the load to be taken up. On the vertical mast of each element can slide a support for a lifting arm integral with cross pieces, the corresponding cross pieces of the supports of the two truck elements being also designed to slide the one into the other. At least one hydraulic jack controls the sliding of the lifting arms.
