3500kg Bevel Gear Machine Screw Jacks

3500kg Bevel Gear Machine Screw Jacks, model JTG40, Tr 63 x 10, 3:1 gear ratio, Translating screw, Keyed screw for non-rotating, and Rotating nut designsSelf-locking occurs when system efficiencies are low enough that the force on the lifting shaft cannot cause the drive system to reverse direction. All bevel gear screw jacks can back drive and require some means of holding the load, such as a brake on the motor. The product specification pages show holding torque values. Holding torque represents the amount of input torque required to restrain the load. In addition to back driving, system inertia usually results in some over travel when the motor is switched off. The inertia of the system should be considered when determining the brake size required to stop a dynamic load.

3500kg Bevel Gear Machine Screw Jacks Features:
* Static load capacity from 3500 kgf. Dynamic load capacity from 2600 kgf. 
* High efficiency, high lifting speed, high duty cycle, long lifespan
* Trapezoidal screw Tr 63 x 10.
* There are no "standard" travel lengths, we process the screw length following customers' need.
* Upright or Inverted mounting. Available in tension or compression loads.
* Translating, Keyed for non-rotating, and Rotating designs.
* Standard with 1-start trapezoidal screw, custom 2-starts trapezoidal screw which offers increased travel speed and require a brake or external locking device to hold position.
* Trapezoidal Screw Ends: top plate, clevis end, plain end, threaded end, fork end, rod end.
* Can be operated by manually operated or by electrical motor driven.
* Single unit use, or complete jacking system including gear motors, bevel gearboxes, connecting shafts and couplings for dual or multiple jack arrangements.
* Simple and effective solution in comparison with hydraulic and pneumatic systems.
