Abstract

In order to increase security at lifting work with in particular high lifting trucks the inventions suggest the use of a weight indication for the driver so that he know how heavy loads he is handling. This weight indication is obtained by measuring the current to the motor of the hydraulic pump. In order to eliminate the risk that momentary variations result in a faulty measurement preferably a mean value of the current is taken for a certain time or this is added during a fixed time interval. Obtained values are them multiplied with a conversion factor so that the weight in for instance kilograms is obtained and delivered to a suitable presentation device. Obtained values may also be used for alarm with suitable sound or light signals if the load should exceed the maximum allowed values.
