The crawler drive is precisely synchronized by an AC frequency conversion servo motor;
The upper crawler uses a cylinder for flexible clamping, automatically adapting to changes in pipe specifications and maintaining good contact pressure with the pipe. The lower crawler is electrically adjusted to the required traction diameter position based on the pipe specifications;
High-friction rubber blocks directly connected to the chain are used;
There are multiple models of traction machines with two, three, four, six, eight, ten, twelve, and sixteen crawlers, suitable for pipe diameter ranges: Φ5-Φ2800mm.
