NM Electric Spiral Screw Lift Jack

Screw jack, also known as a spiral drive mechanism.It is primarily used to convert rotational motion into linear motion or vice versa. There are types that mainly transmit energy, such as spiral presses and jacks; others that primarily transmit motion, like the feed screws of machine tool tables; and still others that adjust the relative positions of parts, such as spiral drive mechanisms. Screw lifts are categorized into sliding friction mechanisms and rolling friction mechanisms.

NM Screw JackThis lifting mechanism is achieved through worm gear and screw drive for operations such as lifting, lowering, advancing, and flipping. It is a fundamental lifting component widely used in various industries including machinery, metallurgy, water conservancy, chemical, culture, and health. It boasts compact structure, small size, light weight, easy installation, flexible operation, high reliability, excellent stability, and long service life. It can be directly driven by an electric motor or other power sources, as well as manually. This series of worm screw lifting machines features self-locking capability and high load-bearing capacity.2.5t to 120t capacity, input speed 1500 rpm, hoisting speed 2.7m/min, various structural types and assembly methods available, working environment temperature from -20 to 100℃, hoisting height customizable to user requirements.

Features of Screw Jack:

1. Smooth transmission, noise-free.

2. Low impact and vibration.

3. Suitable for low-speed, high and low-frequency applications.

4. Primarily for medium to small loads.

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

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

The screw jack system components include: screw jacks, reducers, motors, reversing switches, drive shafts, couplings, brakes, clutches, etc. As long as the client provides specific technical requirements,Engineers will provide detailed calculation procedures, system component selections, and CAD assembly drawings. Our technical support will be professional, and mature, reliable technical solutions will ensure the safety of your equipment.

NM screw jack can be used as a single driving unit or in a multi-screw configuration for a single lift. Multi-screw units with mechanical synchronization are driven by a single motor, making them unsuitable for uneven load distribution and requiring high synchronization of lifting components. Multi-screw units with electrical synchronization have lower requirements for mechanical connection components but require more complex control elements and systems. The configuration of the driving motor, combined with a master-slave layout, can achieve the necessary synchronization of the drive system.

Once the layout is set to your specifications, it can be confirmed.: Worm gear reducer, gear reducer, couplings, connecting shafts, and dumbbell glaze. The installation of the bearing housing can be related to the length of the connecting shaft and its rotational speed.
