The trolley body is made out of stainless steel and the wheels are made of polyoxymethylene (POM) for excellent stability and durability.

The sewer camera centering device is designed for guiding the inspection camera head during the inspection.  It can be used in air ducts, pipes, tubes or other circular channels.   The sewer camera accessory is specifically designed for horizontal inspections.   Every Wohler service camera inspection can be used with this accessory.  The stabilization sleeve and the supplementary light ring must me suitable for the camera head.  Please refer to the users manual for the proper supplemental light rings for your specific Wohler service camera.  Please note, if the camera head is not detachable on you Wohler service camera, the camera rod must be fixed to the holder directly behind the camera head. The locking buttons must be  securely fastened before entering the inspection camera system into the inspection area.  Please note that any permanent adhesives or glues should not be used when attaching this device to your service camera.

The height of the centering device can be fixed in 3 different positions depending on the inside diameter of the pipe that you are inspecting. With this feature is possible to set the ideal distance between the camera head and the interior wall of your inspection area. The wheels are designed so that they cannot be completely removed from the centering device.

Detachable camera heads may also be clamped into the camera head holder when the camera head holder has already been fixed to the centering device. Prior to introducing you inspection camera to the desired inspection area with the trolley the locking button must audibly engage at the final position. In the same way the camera head holder can be fixed under the trolley. This way the camera head can be pushed near the pipe wall.  When the camera head holder is centered under the trolley, the inspection camera head is best protected.  In this specific situation the inspection camera head may be behind wheels of the centering device. The inspection camera rod and the inspection camera head can always be rotated in the camera head holder, even if  accessories are affixed to the inspection camera. The design intent is that the push camera rod will not twist. The inspection camera head and the inspection camera rod can always be rotated in the centering device even with the inspection camera accessories attached.

Clean the inspection camera centering device with water and if necessary you can use compressed air to clear any derris that may be logged behind the wheels.
