Excavators are very common construction machinery. As a machine capable of full-rotation operation, their electrical signals and power transmission during operation are supported by conductive slip rings. As an indispensable piece of equipment in infrastructure construction, their production and sales volume is a barometer of a country's infrastructure development. In March of this year, national excavator sales once again broke historical records, with a total of 49,408 excavators of various types sold nationwide. This also indicates that despite the global economic impact of the COVID-19 pandemic, the market remains optimistic about the development potential of China's infrastructure construction and is willing to bear certain investment risks.
As a leading enterprise in the field of construction machinery slip rings, JINPAT Electronics series of conductive slip rings developed for excavators has always been a flagship product. Many of JINPAT Electronics' excavator conductive slip rings utilize patented technologies independently developed by JINPAT Electronics, possessing advantages such as high stability and reliability. From an appearance standpoint, JINPAT Electronics excavator slip rings are divided into two types: one is the through-hole type, represented by LPTS120-0230-16S and LPT200-0430-0210-06S; the other is the non-through-hole type, represented by LPTS000-0602, LPTS000-0330-1105, and LPTS000-0350-1605.
These three models of excavator slip rings all belong to the custom-designed hollow shaft slip ring series with zero through-holes. They also differ slightly in appearance. For example, LPTS000-0602 has a standard cylindrical shape with wires exiting at both ends, while the latter two are semi-enclosed metal cylinders with their stator wire exits located in the middle of the cylinder, meaning the stator and rotor wires are at right angles.
Having discussed the external aspects, let's move on to the internals. JINPAT Electronics excavator series conductive slip rings utilize professional automotive wiring harnesses, integrating throttle signals, CAN signals, angle signals, encoder signals, and more. JINPAT excavator conductive slip rings also employ patented technology specifically developed for construction machinery slip rings. Their internal structure boasts superior vibration and impact resistance. Combined with high-quality materials, robust quality control, and a highly standardized manufacturing process, this series of conductive slip rings achieves exceptional reliability, ensuring a long-term excavator rotational accuracy of ±2°.
