When the position sensor 26 does not work due to external factors, the travel switch 28 can be triggered to enable the controller to control the active motor 9 to stop.
[0026] In order to better maintain the overall balance of the utility model during hoisting, the length of the main body 15 is further less than twice the distance between the first support 3 and the second support 4.
[0027] Two wire fixing rings are provided on the left end surface of the main body 15 , which can limit the wires at the ends of the main body 15 so that the wires will not deviate too far from the main body 15 .
