Abstract (en)
[origin: US7070061B1] The invention relates to a system for controlling movements of a load lifting device on a horizontal plane whereby the load lifting device ( 6 ) comprises a vertically oriented carrier element ( 14 ). The vertical orientation of said carrier element is at least due to gravity when the element is in a resting position. At least one motor device ( 23 a, 23 b, 23 c) is connected in order to execute said movements. Said movements can be controlled by a force impinging in a substantially horizontal direction relative to the carrier element ( 14 ), in particular a force which can be applied and which can be detected by a sensor device ( 25 ). In order to improve upon a control system in a simple to operate and low cost manner, in particular in such a way that load independent control is achieved with a high degree of positioning accuracy and rapid positioning speed, the sensor device ( 25 ), according to the invention, is embodied in such a manner and arranged in such a manner with respect to the carrier element ( 14 ) that the force is detected in a path-free manner. Path-free in this context is taken to mean that components of the sensor device ( 25 ) do not move through macroscopically registerable path with respect to each other.
