The JWM worm gear screw jack is a fundamental lifting component, known for its compact structure, small size, light weight, wide range of power sources, noiseless operation, easy installation, flexible use, multifunctionality, various matching forms, high reliability, and long service life. It is widely used in industries such as machinery, metallurgy, construction, and hydraulic equipment, offering functions such as lifting, lowering, and—with auxiliary accessories—pushing, flipping, and various height adjustments. It can be used individually or in combination, allowing precise control over lifting or pushing heights according to specific programs, and can be powered by electric motors or other power sources. It comes in different structural and assembly forms, with lifting heights customizable to user requirements.

The JWM type (trapezoidal screw type) is suitable for low-speed, low-frequency applications. Its main components include a precision trapezoidal screw pair and a high-precision worm gear pair. Economical: compact structure, simple operation, easy maintenance. Low speed, low frequency: mainly used for heavy loads, low speeds, and applications not requiring frequent operation. Load holding: the trapezoidal screw has an automatic locking function, enabling it to hold loads even without a braking device. Note: under strong vibration or impact loads, the self-locking function may fail; in such cases, an external braking device should be used.

Features of the JWM screw jack:

◆ Innovative modular design;

◆ Bionic appearance structural design with independent intellectual property rights;

◆ Worm wheels processed using imported German worm hobs;

◆ Thread surface hardened to a surface hardness of 500–550 HV;

◆ Low friction, long service life, high efficiency;

◆ Wide range of power sources, can be directly driven by motors or other power sources, or operated manually;

◆ Diverse output types;
