description The utility model discloses a multifunctional stroke limitator protecting device for a tower crane. The device comprises an input shaft (1), a reduction gear mechanism (2), an adjustable rote memory cam mechanism (3), a WK microswitch (4) and a sensor component (5), wherein the gear transmission mechanism drives the rote memory mechanism synchronous with an output shaft, and uses the microswitch to conduct instantaneous switch on four cams adjusted manually in sequence to realize stroke control and extremity spacing; the gear transmission mechanism drives a sensor synchronous with the output shaft, and outputs corresponding signals to a display instrument to realize instantaneous position display of the stroke. After adoption of the device, the condition that the operation of the tower crane is within the limit position is ensured; accidents are reduced greatly; safe and efficient operation of the tower crane is ensured; human wealth and life safety is ensured.
