Embodiment Construction

[0088] figure 1 An example of the hooklift 100 assembled on a truck 200 is shown. The hookhook 100 comprises a tipping frame 101 connected to a subframe 103 of the hookhook 100 via a tipping joint 102 . The tipping frame 101 is arranged to move relative to the subframe 103 by means of two parallel master cylinders 104 controlled by a hydraulic system 105 . The bottom side 106 of the master cylinder 104 is attached to the subframe 103 and the piston rod 107 of the master cylinder 104 is attached to the tipping frame 101 . The subframe 103 is attached to the chassis 201 of the truck 200 .

[0089] The tipping frame 101 includes a sliding frame 108 , a middle frame 109 and a rear frame 110 . The sliding frame 108 includes a hook 111 by which the lift arm hook 100 is releasably attached to the drop-down platform 300 . The slide frame 108 is connected to the intermediate frame 109 such that a part of the slide frame 108 is disposed inside the intermediate frame 109 and such tha...

Abstract

The present invention relates to a method for determining the mass and the mass center of a demountable platform (300). According to the method, a lift hook is used to lift the demountable platform toa vehicle from the ground; during the lifting process, the physical quantities, which change due to the movement of the lift hook, are measured; on the predetermined values of the physical quantities, the value of the load on the main cylinder of the lift hook can be determined; a mathematical model of the load on the main cylinder taken as the function of the physical quantities is provided; themathematical model is used to determine the mass and mass center of the demountable platform, and the parameters are estimated by iteration program.

Description

technical field [0001] The invention relates to a method for determining the mass and the center of mass of a detachable platform according to the preambles of the appended independent claims. Background technique [0002] A hooklift is widely used in vehicles such as trucks to quickly and easily maneuver a drop-off platform. The hooklift can perform a variety of work tasks such as loading, unloading, tipping and lowering of removable platforms. [0003] Known hooklifts can determine the mass of the drop-down platform. An example of such a hook hook includes a movable weight sensor. Using the hook, the detachable platform is weighed by lifting the detachable platform from the chassis of the vehicle, moving the movable weight sensor under the detachable platform, and then lowering the detachable platform The unloading platform rests on a movable weight sensor for weighing. [0004] A problem associated with the above and other known hooklifts provided with a weighing syst...
