Changyun Technology has obtained ISO 9001, ISO 14001, ISO 45001, and ISO 50001 integrated management system certifications. Our products have also passed CE and EAC certifications. We operate our own sheet metal processing, assembly, and maintenance workshops, with production processes including laser cutting, robotic welding, and automatic bending completed in-house. Before delivery, every machine undergoes strict testing, including pulling force testing, speed testing, and continuous operation

Our key technologies include: Constant-speed cruise control: Maintains stable speed even under load fluctuations. Remote intelligent control: Enables start/stop, speed adjustment, and direction switching from a distance. Multi-machine synchronized control: Allows multiple machines to operate together with synchronized start and stop. 4-speed mechanical gearbox + stepless fine adjustment: Provides flexibility for both slow cable threading and fast cable pulling operations.

Please provide the following project information: Cable outer diameter, Cable weight per meter, Voltage level, Installation length, Number of bends, Required pulling force, Installation method (duct, tray, underground, etc.). Our engineers will recommend the most suitable model and configuration according to your working conditions, helping you avoid unnecessary costs from oversized equipment or insufficient pulling capacity.

We provide a standard warranty period of 12 months commencing from the date of delivery. The warranty covers all manufacturing defects and malfunctions under normal operating conditions. During the warranty period, any product-related issues will be evaluated on a case-by-case basis, and necessary support and services will be provided.
