Tightly structured, easy to operate, and convenient to maintain.

2. Low speed, low frequency: The trapezoidal screw jack is primarily used in applications with heavy loads, low speeds, and infrequent operation.

3. Maintain Load Capacity: The trapezoidal screw lifting machine features an automatic locking function, allowing it to hold the load even without a braking mechanism.

4. The trapezoidal screw lift mechanism has a transmission efficiency of around 20%.
