Crane Control System-Cross Limited Switch for Hoists

Product Description

General description:

The crane limit switch is a safety device which including traveling limit switch and load limit switch. Traveling limit switch used both on crane and hoist or trolley. Load limit switch used on hoist and trolley.Traveling limit switch control the travel of the working machine, while the limit switch control the position of the working machine, and often the terminal position or limit position.

Cross limit switch can stop the crane when driving to the extreme position or near the limit position in order to avoid collision damage to the crane or other equipment.It is usually installed on the inside of the active platform, mainly to install a stroke switch that can be pushed. 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.
3. Slow increase brake life and safety operation.
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.
