Reliable ROVs and crawlers for inspections and maintenance work

Indirect optical inspections allow careful visual checks in places that are difficult to walk on. Thanks to powerful cameras, the inside of shafts, pipes, tanks or structures can be precisely identified. Suitable means of transport are required so that your cameras can safely and reliably reach all the places you want to inspect. Modern magnetic crawlers or pipe crawlers allow you to mount swivelling and rotating cameras. The versatile transport units move safely in narrow pipelines or through difficult-to-access manhole systems. In this way, you can detect and document damage, construction faults, deposits or obstacles. 

Vacuum and magnetic crawlers for a wide range of applications

Trolleys are among the most frequently used transport devices for cameras. Depending on the model and design, they can be used not only for inspections and checks, but also for cleaning work or measuring tasks, for example. Remote-controlled models are suitable for use in hazardous or contaminated environments. Magnetic crawlers are designed for inspection travel on magnetic surfaces, for example in tanks, pipe systems or metallic pressure vessels. Smaller magnetic transport units are ideal for mobile use and can easily climb vertical walls. Larger units are suitable for harsh environments and heavy cameras or tools due to their robust construction. If no magnetic surfaces are available, trolleys with vacuum technology are a good choice. These heavy-duty vacuum trolleys can travel over almost any surface, including overhangs or vertical walls. If you equip them with suitable equipment, they take over control, measurement or maintenance tasks. 

Pipe crabber for indirect optical inspections

The mobile models of the VT CR series pipe crawlers are mainly used for inspections of pipe and manhole systems. To ensure that you have the right device for your inspection work, they are available in different versions. They are suitable for pipe diameters between 50 and 500 mm. Depending on the model, a cable length between 20 and 50 m is available. Thanks to modular designs and optional technical features, the pipe crawlers can be used flexibly. Depending on the application, you can choose waterproofing and different mounting systems for the cameras. All models have a durable housing made of anodised aluminium and spring-loaded legs that adapt to the environment while driving. 

Special equipment for special purposes

The inspection of nuclear applications requires special technical equipment. With inspection systems such as the VT Delfin, a precise visual inspection of reactor pressure vessels and their internals, reactor cooling lines or tanks is possible. The inspection submarine is watertight down to a depth of 50 m and can be manoeuvred in three directions. Powerful, integrated cameras transmit detailed images of their surroundings. With the help of the integrated laser, you can precisely measure cracks, damage or objects. In addition, the submarine is equipped with a gripper arm that can retrieve objects or foreign parts from the tank.
