Abstract

The present application relates to the technical field of lifting equipment, and provides a traction machine and a lifting equipment. The traction machine includes traction pulleys, traction ropes driven by the traction pulleys and fixed pulleys for changing directions of the traction ropes. The fixed pulley is provided with a sensor sensing member rotating with the fixed pulley, a traction machine sensor is arranged beside the fixed pulley; the traction machine sensor is configured to detect a rotation speed of the sensor sensing member, and send the rotation speed to a controller of the traction machine; the controller controls a rotation of the traction pulley according to detected data of the traction machine sensor. Since this kind of traction machine is provided with the sensor sensing member and the traction machine sensor, it is capable of detecting whether the traction machine has an abnormal operation, and stopping the traction machine immediately in an abnormal state.
