Dereli Transmission SWL Screw Jack Lifter螺旋式千斤顶

Spiral screw lift mechanismIt is composed of components such as worm gears, housing, bearings, and lead screws. The working principle is that the motor or manual drive rotates the worm, which in turn drives the worm gear to reduce speed and rotate. The internal cavity of the worm gear is machined into an internal thread, driving the lead screw to move up and down. Due to the presence of worm gears and the reduction effect of the lead screw, it achieves the function of amplifying thrust.
Spiral screw lifting jackBy driving the worm gear to rotate, the screw rod is made to move up and down, achieving the function of pushing, pulling, or lifting. Its functional characteristics are:
1. Standard self-locking performance electric push rods and screw jacks with normal thread leadscrews, due to low comprehensive transmission efficiency, most have dynamic self-locking functions, enhancing the safety of equipment operation; ball screw electric push rods and screw jacks do not self-lock.

Product Features:
Standardization, serialization.
2. The high-speed shaft can rotate in both clockwise and counterclockwise directions.
3. Suitable for low-speed, low-frequency applications; primarily composed of: precision trapezoidal screw and nut sets, and high-precision worm and worm gear sets.
4. Low speed, low frequency: Mainly used in high-load, low-speed environments where frequent operation is not required.
5. Maintain Load Capacity: The trapezoidal screw features an automatic locking function, which can maintain the load capacity even without a braking device.
Note: Under significant vibration or impact loads, the self-locking function may fail. Please add an external braking device at this time.
Technical Specifications:
Speed Enhancement: 150mm/min to 1800mm/min
2. Input Power: 0.55-17.5 kW
Pitch range: 6-25mm
4. Load Range: 2.5T-120T
5. Structural Forms: Direct-connected motor, single input shaft, dual input shaft.

Electric screw jackFeatures:
The worm gear screw jack allows the lifting height to increase accordingly as the pressure load decreases.
2. The worm gear screw jack allows different torques, power, and rotational speeds for lifting various loads, and the power varies with different work continuity rates.
3. Temperature Range for Worm Gear Screw Jack Operation: -20℃ to +80℃.
