Safe Trolley Wire, also known as trolley wire, sliding wire, safe sliding wire, and can also be calledcrane trolley wire, crane trolley wire.Safe trolley wire is used to supply power to moving equipment. It consists of two parts: the sliding rail (fixed part, connected to the power source, usually made of single lengths of 4m/root or 6m/root connected together), and the current collector (sliding part, which can slide on or inside the rail and contact the copper strip to collect electricity, used to connect with the moving motor). Safe trolley wire is safe, insulated, fire-resistant, flame-retardant, temperature-resistant, anti-aging, dust-proof, corrosion-proof, and resistant to sun and rain. Safe trolley wire is used for mobile power supply in various industries such as bridge cranes, overhead cranes, and transport machinery.
Currently, safe trolley wire (tubular, enclosed), single-pole combined trolley wire, rigid trolley wire, multi-level tubular safe trolley wire, seamless safe trolley wire, cable safe trolley wire, and I-beam cable trolleys are commonly used. They have greatly improved in protection level and insulation, making them safe and reliable.
Safe trolley wire——used in dusty, humid environments, can be equipped with dust-proof sealing strips and hand protection (hand protection is needed when the trolley wire is very close to people). The current collector speed is less than 300 meters/minute.
Single-pole combined safe trolley wire——easy to install, fast speed, up to 500 meters/minute (imported trolley wire can achieve this).
Rigid safe trolley wire——used for high-current equipment, current can reach several thousand amperes.
Tubular trolley wire——can be combined according to different pole numbers, current can also reach thousands of amperes.
Safe trolley wirequality can be measured according to the following standards:
1. Carbon brush service life--it is a consumable item, and the travel distance affects the equipment maintenance cycle.
2. Trolley wireshell quality--applicable temperature, environment, etc.
3. Current collector performance--mainly from wheel service life, turning wheel design, and whether the current collector can be used in various environments.
4. Trolley wireexpansion issue--expansion must be considered when the length exceeds 100 meters.
5. Voltage drop issue--the voltage drop varies according to the length of various copper strips.
