*It has variable diameter and variable distance blade, which make it convey the materials smoothly. It also has very low power consumption. The hoist is made of stainless steel , so it is safe and sanitarian. It is very convenient to install and operate it. Range of use: Screw hoist is widely used for lifting and conveying powder, granular, small block materials. *The hoist, which includes mechanical use for lifting and lowering, moving horizontally, or securing a load in position, all with the use of flexible tension members including (according to the appropriate embodiment) chains, wire ropes or straps to apply force and tension. These are activated by a load nut with a threaded connection to a load screw that is provided with rotational drive input. Suitable guides form channel-like spaces alongside the tension members inside the hoist structure through which the flexible tension members travel. These guides maintain the tension members in position even when the tension members are slack, or being fed out of the housing without tension. In most forms of the invention, the guides pass through the load nut. The screw gear applies a positive hold of the applied tension when the screw gear is not being driven, thus holding the load in position.
