Protected against twisting and lightweightSewage channel inspection
This TV inspection system is used for manhole inspections. A camera has to be able to be lowered into the manhole without any twisting or swinging. This is guaranteed by an e-chain® of the E4.21 series without pre-tension. It is wound from a drum and then back onto it again later. This weight-saving solution allowed the equipment to be designed.
