HS High Performance Screw Jack Gearbox

HS high-performance screw-jack gearboxes from ATLANTA make it possible to achieve high feed rates even with heavy loads. Combining power and speed they feature all the advantages of the flexible electro-mechanic drive technology, particularly the exact approach to different positions and an excellent repeatability precision.

The following are typical features of our HT high-performance screw-jack gearboxes:

4 sizes: HS10, HS25, HS50 and HS100
Load capacity: 5-100 kN
Design: rotating, non-rotating spindle, lifting cylinder,
ball screw spindle drive with increased load
Speed: up to 250mm/s
Duty cycle: up to 100%
Operating with 3 phase AC- and servo motor
No self-locking
Engine braking is required

The construction of the HS screw-jack gearboxes is based on the proved design of the ATLANTA servo worm-gear units. In combination with special ball-screw spindle drives with dynamic load capacities far above standard they enable the realization of low-clearance, dynamic, and long-living lifting drives. Due to their compactness the rotating spindle, non-rotating spindle or lifting cylinder designs can be easily
integrated in existing machine concepts.

Because of their precision and robustness the HS highperformance screw-jack gearboxes as linear drives are the ideal drive concept for all dynamic lifting, lowering, feeding, pressing, tilting, and swiveling motions as well as for similar moving processes and very precise positioning.

HS with rotating ball screw drive

Ball screw nut performs the lifting motions
Flange to either above or below
For large strokes it's possible to use a mating bearing flange

Wide range of accessories:

Safety grip nut with cut off (up to HS50 on request)
Bellows
Pivot block for gear unit
and much more

HS with non-rotating ball screw drive

Ball screw drive performs the lifting motions
The spindle moves through the gearbox

Wide range of accessories:

Fixing flange
Swivel head
Spherical plain bearing rod heaed
Protective tube
Twisting protection (as option)
Limit switch set mechanical and inductiv

HS with lifting cylinder

Ball-screw spindle with cylindrical nut in special design
Anti-rotating protection by long key
That's why the ball-screw nut pushs the piston tube outside

Wide range of accessories:

Front connection with articulated joint or with thread
Pivot block for gear unit
Design for outdoor use on request
