发明名称 Safety system for lift trucks
摘要 In order to increase safety of lift trucks, a weight indication for the driver is provided so that the driver may know how heavy a load 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 monetary variations may result in faulty measurements preferably a mean value of current is taken for a certain time or the value of the measured current is added during a fixed time interval. Obtained values are then multiplied by a conversion factor so that the weight in, for instance, kilograms is obtained and delivered to a suitable display device. Obtained values also may be used to provide a warning by sound or light should the load exceed the maximum allowed.
