  • Patent number: 11237037
    Abstract: A hydraulic mass-determining unit arranged for determining the mass of a load held by a hydraulic fluid system, the mass-determining unit is adapted to be connected to a hydraulic pump at a first fluid connection and a hydraulic actuator of a lifting device at a second fluid connection, the mass-determining unit comprises a first pipe arranged for connecting the first fluid connection and the second fluid connection, and at least one pressure sensor arranged to measure the pressure in the first pipe, wherein the mass-determining unit further comprises a flow regulator with a pressure compensator, where the flow regulator is serially connected to the first pipe to regulate the flow in the first pipe, and one of a pressure switch arranged for measuring the pressure difference over the flow regulator, and for sending a signal to the pressure sensor to measure the pressure in the first pipe when the pressure difference is above a preset value, or a magnetic field switch that comprises a magnet attached to the pre

  • Publication number: 20130177374
    Abstract: The invention relates to a load-handling apparatus (1) adapted to be mounted on an elevatable lift carriage of a lift truck, wherein the load-handling apparatus comprises a frame having at least four parallel guides (5, 7, 9, 11) making up a first pair of parallel abutting guides (13) and a second pair of parallel abutting guides (15), at least two oppositely directed and hydraulic actuated piston cylinders, wherein at least two outer load-handling arms are connectable to said hydraulic actuated piston cylinders (25, 27) for moving said outer load-handling arms (3) with regard to said guides to and from each other for engaging a load and at least two inner load-handling arms (4) of which each is connected to at least one spring (101, 103) for keeping a fixed position of said inner load-handling arms to the frame during movement of the outer load-handling arms over a predetermined distance.
