TK3A TK5A hollow guide rails represent upgraded model variants designed to deliver improved structural performance, dimensional stability, and installation efficiency in modern elevator systems. Compared with standard hollow guide rail models, the “A” series is engineered with optimized cross-sectional geometry and tighter manufacturing control to meet higher operational and project requirements.
The TK3A hollow guide rails are an enhanced version of the TK3 model, developed to provide improved guiding stability while maintaining the advantages of lightweight construction. Through refined cross-section design and improved straightness control, TK3A offers more consistent performance in standard passenger elevator installations.
The TK5A hollow guide rails are engineered for applications requiring higher load capacity, greater rigidity, and enhanced ride comfort. Featuring a reinforced hollow structure and increased cross-sectional strength, TK5A rails provide superior resistance to bending and long-term deformation under continuous dynamic operation.
TK3A TK5A hollow guide rails are designed for applications that require a balanced combination of high load capacity, structural stiffness, and reduced system weight. Their reinforced hollow structure makes them particularly suitable for vertical and long-stroke guiding systems where both strength and dimensional stability are critical. One of the primary application fields is elevator systems, where TK3A TK5A guide rails are used to guide car frames and counterweights, ensuring smooth, stable, and safe vertical movement under continuous dynamic loads.
In industrial environments, TK3A TK5A hollow guide rails are widely applied in lifting equipment, automated material handling systems, and heavy-duty linear guiding mechanisms. Their enhanced rigidity supports accurate guidance in systems exposed to vibration, frequent start-stop cycles, or high operational loads. Additionally, these guide rails are well-suited for logistics equipment, industrial hoists, and customized automation solutions where reduced structural mass contributes to improved energy efficiency and easier installation. Across these industry scenarios, TK3A and TK5A hollow guide rails provide reliable guiding performance, long service life, and consistent accuracy in demanding operating conditions.
According to international standards: ISO7465:2007; ISO630: 2021. According to international standards, conduct comprehensive testing of raw materials based on the material certification provided by suppliers to ensure that the quality of each batch of raw materials meets the requirements.
Configure two automated guide rail production lines. The equipment must ensure that the produced items comply with or exceed customer requirements while maintaining the stability of straightness, distortion, and surface roughness
Given the stringent requirements for straightness and twist in BE grade guideways, specialized automatic straightening and twist correction equipment, along with advanced detection systems, have been implemented. The straightness is maintained within 0.5 mm, while the twist is controlled to within 30' per meter
The service concept of "customer first" asserts that, regardless of where our services are delivered—be it within the company, at the client's workplace, on the construction site, or during transportation—our primary objective remains to satisfy the client
