Thank you for viewing. This is a cart that is useful in narrow spaces or places that are difficult to maneuver into. It is very convenient for carrying long and heavy items. I think it will be useful for SD companies, glass companies, and the like. When transporting finished walls and floors during corrective work, it is very easy to transport them vertically. I have used it to transport items that are W2600 x H1500 and weigh 250kg. The main casters are urethane-wrapped, making it difficult for rubber marks to appear, and they have bearings, so they move smoothly. I use casters with a load capacity of 150kg on each side. To prevent it from tipping over, it is slightly tilted with a negative camber (like an eight). *Even with a length of 2600, it does not touch the floor. If you are worried, you can protect it during transport. Completely original production. Please feel free to comment if you have any questions.
