The guide rail elevator is a non-coupled hydraulic lifting equipment, suitable for material transfer between floors in two to three-story industrial factories, restaurants, and dining halls. It has a minimum height of 150-300mm, particularly suitable for work sites where excavation is not possible, and does not require upper suspension points. It comes in various configurations (single-column, double-column, four-column). The equipment operates smoothly, with the guide rail typically made of channel steel, H-beam, or square tube welding. It is easy to operate and reliable, offering an economical and convenient method for material transfer.
