A lift transfer machine is generally used to change the direction of item transportation, moving items from side aisles into or out of the main conveyor line. It features large load capacity, simple structure, and stability and reliability. In roller conveyors and chain conveyors, for items with a sorting speed of less than 30 pieces per minute but a weight of over 2000 kg per item, lift transfer machines are the preferred choice. Advantages of the lifting transfer machine: This device is controlled by a PLC programmable controller, which allows items to be easily transferred in and out of the main and auxiliary conveyor belts without any risk of collisions or compression. The lift transfer machine we have developed uses four-point balanced lifting; even if the items are not placed properly and stress is applied to the sides or corners of the device, it can still lift and lower smoothly, without any obstruction or jamming. The main advantage of the lift transfer machine is its ability to make right-angle turns: it can turn at right angles even in spaces with limited dimensions, which gives it an advantage in terms of space savings. The disadvantages are high costs and a slow conveying speed. Moreover, there are certain requirements regarding the height of the conveyor. After passing through the lifting transfer machine, the original direction of movement of the workpiece changed. Classification of lift transfer machines: Lift transfer machines can be classified based on the method of transfer into cam-driven lifts and cylinder-driven lifts. Based on the type of material being transported, they can be divided into belt-type transfer machines, synchronous belt-type transfer machines, chain-type transfer machines, V-belt-type transfer machines, roller-type transfer machines, etc. Belt-type and synchronous belt-type transfer machines are often used in conjunction with variable-speed chain conveyors, while chain-type transfer machines are typically used with roller conveyors.
