<p>This pendant responsive crane control system has a sensor pendulum (30) arranged above a hoist (50) for the crane (10) and a load sensor (35) for determining the load lifted by the hoist (50). The sensor pendulum (30) serves as a swinging link between the hoist (50) and a crane drive (45) for moving the hoist (50). Lateral movement sensors (32, 33) generate signals in response to lateral movement of the sensor pendulum. A crane control means (40) directs lateral movement of the crane drive (45) in response to the signals generated by these sensors (32, 33, 35). The load sensor (35) used is preferably a load cell or strain gauge incorporated into the sensor pendulum (30).</p> |
