Apparatus for controlling load handling device
An apparatus for controlling a load handling device of an industrial vehicle includes a lifted height detector that detects a lifted height of the load handling device, a tilt angle detector that detects a tilt angle of the load handling device, a loading pump that pumps hydraulic oil from a hydraulic tank in the industrial vehicle and supplies the hydraulic oil to a lift cylinder and a tilt cylinder, a drive that drives the loading pump, and a controller that controls the flow rate of hydraulic oil supplied to the lift cylinder and the tilt cylinder. When the forward tilt angle of the load handling device is greater than a first regulation tilt angle and a lifted height of the load handling device is higher than a predetermined reference height, the controller regulates the flow rate of hydraulic oil supplied to the lift cylinder.
A LEVELLING GROUP FOR AERIAL WORK PLATFORMS
A levelling group of an aerial work platform includes: a support base for supporting a containing cage of an aerial work platform, a support frame hinged to the support base so as to be able to oscillate with respect to an oscillation axis, at least a pair of ground rest elements hinged independently to the support frame, with respect to respective articulation axes parallel to one another and substantially perpendicular to the oscillation axis, such as to be able to independently vary a height thereof with respect to the support base.
CRANE MECHANISM AND WORK PLATFORM WITH LOAD DETECTION MEANS AND INTEGRATED INCLINATION SENSOR
A crane mechanism and a work platform with a load detection apparatus and integrated inclination sensor includes a load cell. The crane mechanism for moving the work platform can be mounted on a base and includes a tiltable boom. The load cell is arranged between the tiltable boom and the work platform as only connection and includes a force sensor and an inclination sensor. The force sensor is configured to detect a force, a lateral or yaw or torsional moment between the crane mechanism and the work platform. The inclination sensor is configured to determine an inclination of the work platform. The force sensor and the inclination sensor have a common housing.
Hydraulic mass-determining unit and a method for determining the mass of a load using the same
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 pressure compensator and a detecting unit arranged for detecting whether the magnet and the pressure compensator are in an initial position, and for sending a signal to the pressure sensor to measure the pressure in the first pipe when the detecting unit detects that the pressure compensator is not in the initial position, and a processor for based on the measured pressure in the first pipe by the pressure sensor calculating a mass of the load.
Lifting vehicle with a transverse stability control system
A lifting vehicle comprising: a frame carrying a front axle and a rear axle; carrying a pair of front wheels and a pair of rear wheels, respectively; a lifting boom articulated in a rear section of the frame; and a stability control system configured to control the conditions of operational stability of the vehicle, wherein said stability control system comprises: a first and a second load sensor configured to provide information about the loads acting on the front right wheel and on the front left wheel and an electronic control unit programmed for: calculating a transverse dimension of the position of the center of gravity of the vehicle according to the values provided by said first load sensor and said second load sensor.
Freight removal regulation apparatus
A method and apparatus to regulate the use and removal of freight. The apparatus includes a sensing element, a stoppage element, and at least one actuator. The sensing element is operable to determine the presence of freight. Stoppage element can alternate between a first condition configured to impede freight removal and a second condition configured to permit freight removal. The presence of freight maintains stoppage element in the first condition absent engagement of the at least one actuator and engagement of the at least one actuator switches stoppage element to the second condition when freight is present.
Loading apparatus
A loading apparatus, in particular for conveying freight over a road surface and loading it into a transporting vehicle and unloading it therefrom, comprises a basic structure, a loading structure, with a freight holder, and a double-action lifting device between the basic structure and the loading structure. The loading structure here comprises a lifting frame, on which the lifting device acts, and a freight carrier, which is mounted on the lifting frame, via a pull-out guide with a pull-out direction oriented transversely to the lifting direction, and has the freight holder. An undercarriage serving for advancing the loading apparatus over the road surface is part of the freight carrier.
