Worm gear machine screw jacks are the workhorses of the lifting industry, available in static capacities up to 250 tons.
Features: They are commonly used to lift, hold, and position loads.
Examples include: Platform lifts, Damper adjustments, Ergonomic lifts, Maintenance lifts, Roll adjustments, Earth Station Antennas, Drilling equipment, Solar Trackers, Conveyor adjustments, Packaging equipment, Gate adjustments, Dam adjustment, and Mine door openers.
An electric linear actuator is used primarily where an intermittent axial movement and positioning is needed. It is a good alternative to hydraulic and pneumatic cylinders due to the simple connection to electrical operational systems and the hygiene benefits.
Electric Linear actuators we offer is based on a worm gear drive. Such actuator is simple and of a sturdy construction. It is based on our worm gearboxes on which a set of cylindrical aluminum tubes and an inner threaded spindle are mounted.
Servo cylinder is the motor forward and reverse rotation motion through the lead screw and screw pair of mechanical motion into a reciprocating motion . The servo motor closed-loop control characteristics , can be very convenient to achieve the precise control of thrust and velocity and position ; the modern motion control technology , numerical control technology and bus technology(Network) , procedures , bus(Network) control . Due to the convenience of the control and the use , the precision motion control of the cylinder and the hydraulic cylinder drive can not be realized .
Trapezoidal Screw Jacks(also named acme screw jacks or self locking Screw Jacks) having high gear ratios and standard design are
generally self-locking and will hold loads without backdriving in the
absence of vibrations.
Ball screw jack is suitable for high speed, high frequency and excellent performance.Main components: Precision ball screw pair and high precision worm-gears pair.Our worm worm gear screw jacks lift and precisely position loads up to 490kN. Upright or inverted jacks operate at full capacity in tension or compression.
(1)Cubic housing jack has the small size, compact and robust structure and mounting versatility.
(2)Cubic screw jacks boast an extensive performance range capable of both compressive and tensile loads。
(3)with a cubic housing shape unite the idea of converting a rotary movement into an axial movement with the aesthetic exterior of the cubic housing to form a functional unit, through which the constructive basic idea of a simple and robust Screw jacks design was ideally realised.
(4)Advantages
Minimisation of the necessary components and maximisation of the effectiveness of these components
Relatively large lifting and moving forces can be realised in the smallest of spaces
The spindle is guided through the housing
The cubic housing shape makes attachment to existing construction elements simple
Manual screw jack (hand wheel screw jacks, hand crank screw jacks, hand operated screw jacks) is driven by a hand wheel or crank or handle. The best advantage is suitable for heavy load, low speed, low service frequency. Lude manual screw jacks have different configuration form and assembly type,and the lifting height can highly customized according to users’ demand, low cost and easy operation.
Electric Screw Jack can also be called motorized screw jack, it includes a worm gear screw jack and an electric motor.The screw jack can be self-locking acme screw jack or high precision ball screw jack.The motor can be high precision servo motor,stepper motor,helical gear motor, worm gear motor, 3-phase asynchronous motor and 12v,24v,48v do motor and dc gear motor etc.
The advantages of worm gear screw elevator linkage, the worm gear screw elevator platform (screw lifting platform) is a mechatronic motion execution unit that cleverly combines the motor, reducer, steering gear, worm gear and worm elevator through couplings, connecting rods, etc.
1.Compact structure.
2.Small size, light weight, wide power source.
3.No noise, easy installation, flexible use, and multiple functions.
4.There are many types of suits, high reliability and long service life.
5.Simple structure, easy processing, low cost, large transmission axial force, self-locking, high positioning.
Types of screw jacks Appliance
Screw jack is applied to all fields for lifting or pulling, such as Aircraft maintenance platform, Solar plate, machinery, metallurgy,
water conservancy, medical treatment, chemical industry, culture and hygienist etc.
Lude screw jacks, linear actuators and electric cylinders are routinely used to:
Maintain adjustment of large rolls in steel mill operations
Operate maintenance and material lifts for many industries
Adjust conveyor height in machinery
Move and support huge structural elements used in municipal projects
Stabilize and deploy equipment used in heavy mining and drilling operations
Operate gantry systems for dockside and other operations
