| Machine screw and ball screw actuators can be used in a single arrangement or can be used in a multiple arrangement along with a complete line of accessories to provide for a mechanically interconnected and permanently synchronized system. With readily available accessories, connecting shafts can be coupled to the actuator, gear boxes can provide for the rotation and connection for a multiple actuator arrangement, and limit switches can be used to limit travel and provide for an up-stop and down-stop. Bellows boots to protect the actuator from dirt and other contaminants and allow for longer life are available in both upright and inverted screw styles. | |||||||||
8-Jacks System
JACTON
Product Description
Synchronisation of eight worm gear screw jacks is simple with the complete range of accessories. Universal joint shafts are used to connect several worm gear screw jacks together. The shafts attenuate noise, vibrations and impacts and compensate for axial, radial and angular errors. The spiral bevel gear boxes offer numerous advantages to the designer and have been specially selected to complement the worm gear screw jacks and accessories. Eight of the most popular system configurations are the "H" and "HH" configured lift systems. Screw jacks with safety devices for lifting platforms. Lift devices cover Lifting tables, Lift work platforms, Loading platforms, Car hoists, Stages and studios, Stage mechanics, safety equipment.
Main Features
* Simultaneously lifting, load-supporting from several kilograms to heavy duty several hundreds tons.
* 8-jacks system efficiency 80%. If add bevel gearbox for the jacking system, don't ignore bevel gearboxes efficiency 94%.
* Self-locking (hold the position), precision positioning, full synchronization, different multiple screw jacks systems arrangements, easy installation and operation, maintenance free.
* Lifting screw with non-standard lengths, maximum stroke 6000 mm in compression load or tension load.
* Translating Screw Jack System: The lead screw ends are to be attached to a common load. Clearance is required under the bottom mounting plane of the jack body to accommodate the translating screw cover.
* Rotating Screw Jack System: The lifting nuts translate. Clearance under the bottom mounting plane of the jack body is not required but allowance must be made in the lifting platen design to allow the platen to pass over or past the lifting sSelf-locking trapezoidal screw (the load does not lower in the event of a system failure)crew.
* Upright or Inverted mounting. Available in tension or compression loads.
* Standard with 1-start thread screw, custom 2-starts threads screw which offers increased travel speed and require a brake or external locking device to hold position.
* Can be operated by hand wheels, motor or both
* Simple and inexpensive solution in comparison with hydraulic and pneumatic systems.

Application Case
Synchronization Screw Jack Lifting Systems offer comprehensive lifting, lowering, pushing, pulling and position holding with precision for design solutions in a wide variety of industries. These jacking systems are found in markets including platform synchronous lifting systems such as lift tables and landing stage, material handling equipment, steel works equipment, food and beverage industry, water processing, pharmaceutical, medical and laboratory equipment, packaging equipment, nuclear and aerospace, paper and printing industry equipment, satellite earth station antenna system, heavy vehicle lifting, solar panel tracking systems, bending machine, conveyor equipment, theatre and stage construction and military among others.
The Main Advantages of a screw jack system over hydraulic, pneumatic or chain driven lift drive system are:
* Controlled Lift with mechanically linked Screw Jacks in each corner.
* Synchronized lift with No skewing or tilting of frame throughout the travel stroke.
* Compact Worm Gear Screw jack bodies.
* Self-locking trapezoidal screw (the load does not lower in the event of a system failure)
* Low input power, High lifting linear force, High repeat and Positional accuracy.
* Feature: Single, Clean, electric motor drive, easy to install.
* Just one motor is required with Brake, feedback options. No oil contamination issues.
* Variable Speed through inverter control.
* With Inverter driven motor, soft start and stop, current management, varying lift speeds are all available.
