Introduction to Crane Sliding Contact Line
The crane sliding contact line, also known as sliding contact line or safe sliding contact line, is used to supply power to moving equipment. It consists of two parts: the sliding line guide rail (fixed part, connected to the power source, usually made of single lengths of 4.5m/piece or 6m/piece connected together), and the current collector (sliding part, which can slide on or inside the sliding line track and contact the copper bar to collect electricity, used to connect with the moving motor).
Safe sliding contact lines (tubular, enclosed), busbar sliding contact lines, rigid sliding contact lines, and single-pole sliding contact lines are commonly used. They have significant improvements in protection level and insulation, making them safe and reliable.
Safe sliding contact line——Used in dusty, humid environments, can be equipped with dustproof sealing strips and hand protection (when the sliding contact line is very close to people, hand protection such as AKAPP should be provided). The current collector speed is less than 300 meters/minute.
QYG multi-pole sliding contact line——Easy installation, fast speed, simple and compact structure, safe and reliable, easy maintenance.
QYT rigid sliding contact line——Used for high-current equipment, with current up to several thousand amperes. Widely used in environments with high temperature, high humidity, high voltage, strong corrosion, and heavy dust.
QYH single-pole sliding contact line——Can be combined according to different numbers of poles, with current up to thousand amperes.
The quality of sliding contact lines 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. (Crane sliding contact line) Shell quality of sliding contact line--Applicable temperature, environment, etc.
3. Current collector performance--Mainly from the wheel service life, turning wheel design, and whether the current collector can meet various environmental conditions.
4. Expansion issue of sliding contact line--Expansion must be considered when the length exceeds 100 meters.
5. Voltage drop issue--The voltage drop varies according to the length of different copper bars.
