Controlling jaws clamping force in lifting truck involves controlling force according to matrix in memory giving force required for each load weight read from load codes before picking up load

摘要

The method involves associating a weight code with the loads (20) in manufacturing, reading the code before picking up the load, transferring the associated weight to a computer (31) with a memory unit (32) and controlling the clamping force according to a matrix in memory giving force required for each load weight. Independent claims are also included for the following: a device for controlling the jaws clamping force in a lifting truck.
