Overview of JW screw lift

A JWM worm screw elevator (trapezoidal screw type) is suitable for low-speed and low-frequency applications. Its main components are a precision trapezoidal screw pair and a main precision worm gear pair.  

Characteristics of JWM worm screw elevator:

Economy: Compact structure, easy operation, and convenient maintenance.  

2. Low speed and low frequency: mainly used in places with high loads, low speeds, and no need for frequent work.  

3. Maintain load: The trapezoidal screw has an automatic locking function, which can maintain load even without a braking device.  

*When JWM worm screw elevator is subjected to large vibrations and impact loads, the self-locking function may occasionally fail, and a braking device must be applied in this case.

The JWB type worm screw elevator (ordinary ball screw type) is suitable for high-speed, high-frequency, and high-performance devices. Its main components are precision ball screw pairs and high-precision worm gear pairs.  

Characteristics of JWB type worm screw elevator:

1. High efficiency: By using rolling friction, the overall efficiency of the machine is improved, and only a small driving source is needed to generate a large driving force.  

2. High speed: Compared with trapezoidal screws, the speed has been greatly improved, making it easy and high-speed to operate.  

3. Long service life: High quality ball screw is used to increase its working life by more than 3 times.

The nut rotates and the screw moves up and down, which is the assembly of a regular elevator

US: Attach DS: Lift down

*Please choose the appropriate elevator (up or down) based on the direction of the load and installation direction

*When the screw shaft is lifted or lowered, it will generate rotational force, so measures must be taken to prevent rotation.

Spin arrest structures (UM, DM)

UM: Attach DM: Hang down

Suitable for situations where there is no connection at the top and the rope cannot be prevented from rotating due to the pulley being pulled around

Please choose the appropriate elevator (UM or DM) based on the load direction and installation direction

Active Nut Construction (UR, DR)

In general, elevators must have the travel required by the lifting of the screw shaft and the space needed for the screw cover. If you want to increase the travel in limited space, using this movable nut structure is very suitable (the screw shaft rotates, the movable nut moves). The top of the screw shaft is cylindrical, so when traveling long distances, using a support method at the shaft end can achieve good results.

UR: Attach DR: Lift down

Please choose the appropriate elevator (up or down) based on the direction of the load and installation direction

Note: In the selection and model representation methods, the placement direction of the nut should also be indicated.
