Seamless crane conductor bus bar can be used for electric hoist, electric beam and electric single girder bridge crane; stacker, automatic detection line for electromechanical products, automated production line, mobile power tools and other mobile power receiving equipment, as well as factories, mines, workshops. At present, the H class safety bus bar is generally used, which has great improvement in protection level and insulation, and is safe and reliable.
Features
1. It is easy for installation and daily maintenance with combined design, especially suitable for working at heights.
2. It has long service life and unique conductor jacket design, which greatly extends the service life of the bus bar system.
3. It is safe and reliable, that is, there is no danger of electric shock when using finger contact, and it complies with IP23 standard.
Specification
1. Safety: the bus bar is made of engineering plastic with high insulation performance. The enclosure protection level can be IP13. IP55 is needed to protect against rain, snow, frost and freezing attacks as well as foreign objects. The bus bar is subject to a variety of environmental conditions.
2. Reliability: the bus bar has excellent electrical conductivity, fast heat dissipation, low impedance value and low line loss. The brush is made up of a metal copper or carbon alloy material having high electrical conductivity and high wear resistance. The conductive device has flexible movement and good directional performance, which effectively controls the contact arc and the arc phenomenon.
3. Economy: seamless crane conductor bus bar has simple structure, high allowable current density, low resistivity and low voltage loss, and can save about 10% of electricity. It realizes plastic-made steel to replace copper with plastic.

Sinoko’s seamless bus bar is a joint-free conductor rail system—except at the line feed point—that safely and reliably supplies electricity to moving machinery like electric hoists and bridge cranes. Its streamlined design reduces connection points and potential failure spots.
This system offers compact design, easy installation, strong insulation with PVC housing, long service life, and IP13 to IP55 protection levels. It's impact- and UV-resistant, making it ideal for curved rail hoists and low-frequency operation.
Equipped with high allowable current density, low resistivity, and efficient heat dissipation, Sinoko’s seamless bus bar reduces line losses and can save around 10% in electricity usage compared to traditional systems.
Yes—its engineering plastic construction offers excellent insulation, and it complies with IP23 (with some configurations supporting up to IP55), ensuring user safety even if someone touches it mistakenly.
It’s highly versatile—suitable for electric hoists, beams, single‑girder cranes, stackers, production lines, mobile power tools, workshops, factories, and mines. The durable PVC housing also makes it ideal for UV-exposed and impact-prone settings.
While designed for durability, the collector shoes may require periodic replacement due to wear. Additionally, this system is not suitable for explosion‑proof applications or mobile transfer carts and should be inspected regularly to ensure reliability.
