CCTV inspection crawler system for municipal sewer pipe network of big diameters

CCTV crawler Precautions during an inspection operation

The connecting cable only has the tensile strength that meets the operational requirements. When using, pay attention to avoid the crushing of the cable by heavy objects to avoid damage to the cable.

When placing the instrument into the well for inspection, pay attention to protecting the lens to avoid friction and collision between the lens and the manhole well wall or the bottom of the well.

When the crawler travels in the pipeline, do not rotate and move the lens. If you need to rotate or move the lens, you should stop the crawling motion first to observe.

When operating the crawler to move forward or backward normally, keep the lens facing directly ahead of the pipeline.

When the lens has been rotated to an angle (in the abnormal state), and the crawler needs to move forward or backward, pay attention to slow down the speed.

When the on-site failure of the crawler, camera lens, operation panel, cable car, dedicated touch terminal, operating handle, etc. is urgently needed to handle, it must be handled by the technical personnel with maintenance experience. Generally, when the instrument fails in the warranty period, it shall be handled by the professional maintenance personnel of the seller. Any personnel unrelated to the maintenance of the above instruments and devices are prohibited to disassemble and assembling without permission.

Do not operate the device with the disease, and when the device is operating with abnormal air pressure value, it must be recovered immediately to check the failure.

Rough work is strictly prohibited, and the device must be installed and operated in strict accordance with the operating specifications and correct procedures.

The crawler inspection is only applicable to the inspection of acceptance pipelines and operating pipelines with a water level lower than 10% of the pipe diameter, without siltation, and with a pipe diameter greater than DN250.

When moving forward in the pipeline, operate the device slowly, observe the road ahead carefully, and make sure that the device ahead can be passed before operating. The company will not be responsible for stuck and overturn due to operation problems.
