Another at the end of the track (running limit position) to install a fixed limit position of the baffle. When the crane operation to the position, limit baffle will touch the limit switch, cut off the control of the power of walking, then crane can only traveling to the opposite direction when closing.

Nante suns limit switch is used to two speed, slowing down and stopping two-way limit.There are two type of the limit switch :180°200mm or 300mm and 360°200mm or 300mm.It has the following characteristics:

1. Limit the cart and the car walks, make big, the car near the rail end automatically slow down and stop.
2. Apply to some forbidden area need to crane on car steering.

4. High-quality drive and control technology.
5. Switchover (fast/slow) and limiting in both directions of travel.
6. The shell is made of aluminum alloy.
7. Have automatic reset function.
8. The all-round rubber seal provides optimum protection against dust and water, so that protection degree IP66 can be achieved without any problems.
