| 摘要 |
This pendant responsive crane control system has a sensor pendulum arranged above a hoist for the crane and a load sensor for determining the load lifted by the hoist. The sensor pendulum serves as a swinging link between the hoist and a crane drive for moving the hoist. Lateral movement sensors generate signals in response to lateral movement of the sensor pendulum. A crane control means directs lateral movement of the crane drive in response to the signals generated by these sensors. The load sensor used is preferably a load cell or strain gauge incorporated into the sensor pendulum.
