Helical Gear ElevatorEquipped with multiple functions such as lifting, advancing, descending, and flipping, it can accurately control the length of lifting or advancing according to a certain program. In the case of multiple units联动, it can bypass the bevel gear shift mechanism and directly connect. It can be powered by an electric motor or other sources, and can also be operated manually. The input speed is 500 rpm, with a lifting speed of 2.7 m/min. It offers various structural designs, with lifting heights customizable to customer requirements. The device typically features an automatic locking function.
