Crab Robot Camera for Vertical Pipe Inspections
The CRAB-ROBOT is modularly designed and can be retrofitted quickly and without any special tools for the specified tests and inspections. This new system embodies and reflects 30 years of practical experience in the fields of designing, developing and manufacturing video-endoscopic systems and testing them in close cooperation with our customers.
The CRAB-ROBOT is suitable for pipelines with diameters ranging from about 50 mm to 1000 mm and a length of up to approx.200 m. The length of the cables depends on the diameter or the size of the robot, on the internal surfaces of the pipelines and on the number of pipe bends to be passed. Pipe bends of 1,5 x D, changes in the pipe’s cross-section, slight deformations or sagging weld seams will be negotiated without any problems. Even pipelines branching off on the sides can be passed safely, without the spring-loaded drive arms getting off course or blocked
Features & Benefits
- Multi-functional use and easy handling,
- Modularly designed controls,
- Due to the modular design, customized and user-specific modifications can be carried out quickly and in a cost-effective way,
- Light-intensive illumination system with powerful white-light LEDs (8000 K colour temperature),
- Pan/Tilt camera-modules
- Exchangeable camera heads with integrated lighting rings,
- Manual or remotely-controlled focusing,
- Negotiation of the smallest pipe bends of 1xd by the system without any problems,
- Minor obstacles, uneven surfaces and changes in the cross-section will be automatically adjusted.
Control unit: A new compact and portable control-panel and a small cable reel with gold plated slip-rings guarantees a trouble-free signal assignment to the rear connection box. The new control panel has a built-in control-unit and comes as a standard with installed 10 “LCD monitor and optional digital DVR with for the video recording.
Drive unit: The CRAB-ROBOT consists largely of a drive unit and different video heads, the latter being either permanently fixed in the drive module or easily exchangeable by a plug-in coupling system. Each module is equipped with 6 spring-loaded drive units. Powerful miniature motors with combined planetary transmissions, 32 radial ball bearings and 12 wheels with a specific rubber coating will ensure maximum traction and thus the safe passage inside the pipelines, even if they have rough or smooth surfaces. The six drive arms which are individually spring-loaded will ensure that the device is precisely located in the centre of the pipe and that uneven surfaces, as well as minor changes in the cross-section, can be automatically negotiated. Depending on the actual application, the CRAB-ROBOT can also be equipped with different video heads for direct viewing or with Pan&Tilt camera modules. A high-resolution 1/3″ CCD miniature colour sensor (optionally with fixed or remote focus) will ensure the transmission of sharp video images in superior colour fidelity. Despite its small size, the CRAB-ROBOT is of a robust design and does not require any maintenance or operational skills. Variants and customized modifications can be implemented speedily and supplied at favourable prices on request.
