Principles and Advantages of Cable Reel-Powered Rail Transfer Cart
1. Core working principle
Power supply connection: directly connected to the 380V/220V industrial power grid through oil resistant and tensile resistant cables, without the need for battery energy storage;
Roll retraction: The roll automatically moves with the vehicle body - releasing the cable when moving forward and retracting the cable when moving backward to avoid cable dragging and entanglement;
Power transmission: The cable sends electrical energy to the motor reducer, driving the wheels to run along the track, with built-in protective devices to prevent power supply failures.
2, Core advantages
1. Long distance continuous operation without the need for intermediate charging
Directly taking power from the grid, eliminating battery life limitations, and supporting 24-hour uninterrupted operation (such as Molten Steel ladle transportation in steel plants and segmented transportation of ship hulls in shipyards).
Adapt to 100-1000 meter long tracks, solve the problems of "frequent stopping and charging of battery cars" and "long-distance voltage attenuation of low-voltage tracks", without affecting the production rhythm at all.
2. Simple structure and low maintenance cost
No vulnerable components such as battery packs, chargers, BMS management systems, etc., daily maintenance only requires "checking cable wear" and "adjusting drum tension" (1-2 times a month);
The maintenance cost is 30% -50% lower than battery powered models, and there is no need to regularly replace expensive batteries (a set of lithium batteries costs about 30000 to 100000 yuan), making long-term use more cost-effective.
3. Strong overload capability and high environmental adaptability
A single load can cover 5-500 tons, which can meet the "overload transportation needs" of heavy machinery plants and nuclear power equipment plants (such as transporting 200 ton large machine tool bed bodies);
The cable is made of oil resistant, flame-retardant, and cold resistant materials, and can work in environments ranging from -20 ℃ to 60 ℃. It is not afraid of workshop oil stains, dust, and high temperatures, and is suitable for harsh industrial scenarios.
4. Stable power supply and high safety
There is no voltage loss throughout the entire process (different from low-voltage rail power supply), and the motor always runs at full power to avoid "insufficient power under heavy load";
Comes with cable breakage protection: If the cable is accidentally pulled, the drum will immediately lock to prevent cable damage or electric shock risk.
">, explosion-proof environments, etc. The mechanism is relatively simple and the cost is low. It is a common transport vehicle for on-site crossing. Compared with the battery series transport vehicles, its use time is not limited on the track. Compared with power supply series transport vehicles, track laying requirements are not high. This series of vehicles is suitable for occasions with any loading capacity and high frequency of use. When the running distance exceeds 50 meters, a router is required to auxiliary winding, and the maximum running distance can reach 200-400 meters. This series of electric flat cars are suitable for lifting and metallurgical use in harsh industrial and mining environments. The flat cars have a simple and reliable structure, are economical in price, convenient for maintenance and convenient for track construction. They are an alternative to traditional electric flat cars and are suitable for large-tonnage spanning solutions.
