Availability around the clock: Encoders for positioning and speed measuring.

Whether for portal cranes, container loading bridges or stacker cranes, the requirements for automation and safety are ever-increasing. Kübler encoders measure the position at the cable hoisting gear, at the travel gear rail-bound or with rubber tires and at the spreader. The sturdy and safe measuring equipment makes an automatic container positioning possible in the first place. Our products have been reliably used in this field for years. The result is a high system availability. Kübler sensors have been providing top performance for decades in portal cranes in shipping ports and overhead cranes in production lines or steel plants. You can trust our encoders too.
