| Screw jacks lifting systems offer wide-ranging lifting and positioning solutions for diverse industries. Our robust jacks reliably move and accurately position loads up to 100-tons. We configures jacks with components such as motors, gear reducers, shafting, coupling, and motion control devices to create complete multiple jack systems. Mechanical screw jacks can be operated by manually or by electrical motor. More than one screw jacks can be connected together to move simultaneously. | |||||||||
4-Jacks System
JACTON
Product Description
A typical modular Synchronization Four Screw Jack Lifting Systems with trapezoidal (acme) lead screw may consist of a number of screw jacks connected to gearboxes and driveshafts to provide very accurate, reliable lifting/positioning solutions. Due to the system architecture screw jacks are inherently clean in their operation with no contaminants to be released to their environment. If multiple machine screw jacks are connected in a mechanically linked system then the complete system may be considered self-locking. Alternatively, to be sure, include a brake on the system either as a stand alone device or as a brake motor. Four of the most popular system configurations are the "U", "H", "HI", "UI", "T" and "TT" configured lift systems.
Main Features
* Simultaneously lifting, load-supporting from several kilograms to heavy duty several hundreds tons.
* 4-jacks system efficiency 85%. 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.
