This CE standard SWL screw jack is a high-performance industrial lifting equipment with optional ball screw and T type screw structures, realizing flexible switching between hand crank manual operation and electric lifting to meet diverse working condition demands. The equipment can be combined to build a small synchronous lifting platform, achieving stable multi-point synchronous lifting with strong load-bearing capacity, compact size and easy installation. It is widely applied to lifting adjustment, station positioning and mechanical matching in mechanical processing, automatic production lines, warehousing logistics and other industrial fields, with reliable performance and long service life.

Featuring a compact design and high-efficiency transmission, this lift utilizes a rolled screw for low rolling friction loss and high transmission efficiency. Its robust construction includes a cast iron housing, a wear-resistant 94-copper worm gear, a worm shaft, and a precision lead screw.(Lifter models, speed ratios, strokes,vary.Please contact our for details.)

SWL Worm Gear Screw Lifter

1.Profile

Worm wheel screw elevator is widely applied in industries such as machinery, metallurgy. construction, and hydraulic equipment,and has many functions such as lifting and pushing and turning with the help of accessories or adjusting height and position.This series worm screw elevator is one model of basic hoisting parts and has numerous features of compact structure, small volume,lightweight,widedrivesourses,lownoise,highreliability,and long lifespan.In addition,they are easy to be mounted,flesible in use and enjoy multiple functions. This series, driven by motor or other power or manually, can be used both single and combined with others to accurately control the height of lifting or pushing by certain programs.For there are many structures and mounting positions, the lifting height can be adjusted to the customers requirements.

(1)SWL/HKTrapezoid scew-LOW SPEED LOW FREQUENCY

SWL/HK Trapezoid scew is suitable for low speed and low frequency. Main components: Precision trapezoid screw pair and high precision worm-gears pair.

①: Economical: Compact design, easy operation, convenient maintenance.

②: Low speed, low frequency: Be suitable for heavy load, low speed, low sewice frequency.

③: Self-lock Trapezoid screw has self-lock function, it can hold up load without braking device when screw stops traveling.

Braking device equippet for self-lock will be of malfunction accidentally when large jolt & impact load occur.

(2)SWLG/HKG (General ball screw) is suitable for high speed, high frequency and excellent performance. Main components: Precision ball screw pair and high precision worm-gear pair.

①High efficiency: Rolling friction improve efficiency greatly, only a little drive power can generate great thrust force.

②High speed: Rolling friction speed up travel of screw easily.

③Lifetime longer: High precision ball screw can make SWLG lifetime longer by 3 times comparing with SWLG/HKG.

Braking devices or motor with braking devices are necessary when choosing SWLG/HKG.
