Collector by angle brackets to the electrical equipment, and through the power brushes trolley line to boot to the electrical equipment. Brush is a key component of the current collector, the company's patented alloy of copper graphite brushes formula, a special heat treatment process is made, wear resistance, service life is 4-5 times that of similar products. Special collector by ABS plastic and stainless steel components, which can horizontal and vertical two-way adjustable, so each swing of more than 90 degrees to achieve a three-dimensional movement, to ensure uninterrupted power supply. Collector rod using vulcanized treated alloy steel, enhances its anti-oxidation, corrosion resistance; high-quality stainless steel spring, improved carbon brush contact with the trolley line safety, to avoid electrical hazards.
