The Maximum Stroke of Screw Jack

Sometimes customers ask"What is the maximum stroke of the screw jack?" Today let's learn something about the long travel of the screw jack.


Usually the maximum travel of a single worm screw jack lift is 3-4M. If this length is exceeded, the screw rod is easily to get deformed and bent during use, especially when the jack is used to raise the object.


Larger Screw Jacks have their maximum raise / stroke available limited only by the available length of bar stock from suppliers (note - special steel production runs can be organised for special applications) and the practical ability to handle, machine and transport the lead screw and the complete screw jack. Practical lengths will also be affected by whether the screw is to be subjected to compression or tension loads. Depending on diameter the length can be limited due to deformation of material in the machining process or column strength of the screw when subjected to compression loads.

Screw Jack Screw Top End Type & Function

图片
Our commonly used worm gear screw lifts have a total of four screw top end types: plain end, top plate, threaded, and clevis end. These four functions are different, and customers can choose different end types according to their actual use. Worm gear screw lifts are divided into two types according to the structural form. Type I namely translating type, above four end types are available, Type II,namely rotating type, only plain end and threaded end are available . The reason why the type II has no top plate type and clevis end type is because for the type II copper nut must be installed. After installation, the flange or clevis end can no longer be installed. Now let’s see the functions of the four types of screw top end: Plain end type, can be installed on the fixed bearing; top plate type, can directly lift the object , but the flange also can be connected with other equipment; Threaded end type, can be connected with other equipment through the thread, us

Electric Linear Actuator for Sluice Gate

图片
The electric linear actuator is a device that converts the rotational motion of an electric motor into linear motion (push or pull movement) and it can be used anywhere a machine pushes or pulls a load, raises or lowers a load, roughly positions a load, or rotates a load. It is has similar function as worm gear screw jack. As we have mentioned in early articles , t he trapezoidal worm gear screw jack can be used for sluice gate. In fact, electric linear actuator can also be used for sluice gate, usually it is light duty gate. The following picture shows l ighter duty Stainless Steel or Aluminum frames and blades using a compact controller system and Linear Actuators . Designed especially for On-Farm canal  and irrigation control, Check and Delivery gates, where the heaviest duty frame and actuator system is not required.
