Multiple interconnected electric screw jack lifting machines

The worm screw lifting machine work platform consists of one or more lifting machines, powered by a motor (or handwheel) and coordinated with other components for synchronized and smooth lifting.

For screw jack work platforms, whether it's a two, three, or four-column drive, we recommend using a single motor to power them as much as possible. This is because each motor has a speed difference per minute, making it difficult to achieve synchronization and stability with multiple drives.

The common combination methods for screw jack platforms are two units, four units, eight units, etc. Two units are connected in tandem.I and T models are available. Compared to the T model where the driving source is in the middle, the elevator experiences more even force distribution, resulting in a more stable transmission effect. Four interconnected models are available: T, U, and H shapes. The H shape includes the development version and 2H shape for multiple combinations. Customers can choose according to their own installation space and other requirements. For more selection options, please consult our technical staff.

Composed of a worm gear reducer and a lifting screw, the reduction component utilizes worm gears. It reduces speed by the worm driving the worm gear. The worm gear center features an internal threaded structure, akin to the nut of the lifting screw, and is compatible with it.

The lifting speed of the reducer is equal to the input speed of the worm divided by the reduction ratio of the worm and worm gear, then multiplied by the pitch of the lifting screw. Due to its structure, it is generally lubricated with grease; some series use oil lubrication, which offers the advantages of longer lifespan and more stable operation compared to grease lubrication.

Features of Screw Jacks

Smooth transmission, noise-free.

2. Low impact vibration

3. Suitable for low speeds and both high and low frequency applications.

4. Primarily for medium to low loads.

5. Maintain Load Capacity: The trapezoidal screw features an automatic locking function, enabling load capacity to be maintained even without a braking device.

6. Safety Setting: To prevent overtravel and damage to the screw and nut, a travel switch is specifically configured.

Product Features:
Standardization and serialization
2. The high-speed shaft can rotate in both clockwise and counterclockwise directions.
3. Suitable for low-speed, low-frequency applications, the main components include: precision trapezoidal screw and high-precision worm gear sets.
4. Low speed, low frequency: Mainly used in high-load, low-speed operations and environments that do not require frequent use.
5. Maintain Load Capacity: The trapezoidal screw features an automatic locking function, allowing it to maintain load capacity even without a braking device.
Note: Under conditions of significant vibration or impact loads, the self-locking function may fail. Please add an external braking device in such cases.
