What is the electric hoist limiter
Electric hoist rose to a certain degree, the outstanding blocks on the guide rope device will overwhelm a travel switch, stop rising, prevent hook shells hit the electric hoist wire rope, down to a certain degree after will also drive the trip switch, stop down, to prevent the broken wire rope, the stroke switch device is the electric hoist limiter
General stop referring to disconnect the secondary loop limiter, firearms refers to disconnect the fault in the main circuit of three-phase two-phase broken fire stop Electric hoist limiter and fire stop on the effect is the same,
It is a kind of protection device that when the electric gourd rises or falls to a certain level automatically disconnecting the power supply, the common have broken fire, heavy and so on
Electric hoist limit, it is through the gear speed reducer connected by up and down two CAM group, each group of CAM is composed of three different Angle each other of CAM, and two groups of CAM on the driven shaft are solid and even in the same root, corresponding to each CAM only placed one only for position switch, so that the utility model has simple structure, easy to use safety, good reliability, it can fault phase protection.
