Powerplate concept
The Powerplate concept gives users the most straightforward access to automation.
Hydraulic actuators (from 1 to 7 pcs ) are built-in under a base plate, and the cylinder package can also be moved to various additional positions under the plate for optimal clamping. So,either a single workpiece can be clamped alone or up to 14 pcs simultaneously.
The Hydraulic actuator normally uses HA-VD1, creating a 29 kN clamping force with 350 bar maximum hydraulic pressure.
Fixtures can also be built on sub plates, which can be rapidly changed using a built-in Ball-Lock quick-change system.
Generic-purpose OK-VISE Fixturing Concept components like Multi-Rail RM units can be installed directly on the plate.
There are two sizes as standard : 240x400 mm and 400x700 mm
PP2VD5-2440A Powerplate unit
PP2VD5-2440A with RM option
Plate size 240 x 400 mm.
Hydraulic cylinder package ( 2 actuators ) can be installed in the middle or at the end of the plate.
Positioning holes for RM-400 Multi-Rail units are included.
Applications
POWERPLATE WITH SUB-PLATE
Hydraulic actuator sets HA-JB1, HA-JD1, HA-VB1 and HA-VD1
In addition to hydraulic actuators (= cylinders) these sets include all the adapter bolts and fittings required to automatize B- or D-series clamps.
Depending on the clamp size, a 8 mm or 12 mm bolt goes through the clamp and fixture plate to the cylinder ‘s piston. The base cylinder is bolted on to a fixture plate.
The cylinders in the sets are single-acting, enabling the simplest possible actuation of OK-VISE clamps

STEP (3D) | X |
The hydraulic actuator HA-1S1 is extremely small - only 50 mm in height. Still, using, for example, any of OK-VISE D-series clamps, it can create a 4.4 mm (2 x 2.2 mm) clamping stroke. Single acting hydraulic function ( with powerful return spring ) is simpliest to operate but the actuator can alsobe used in double acting mode. If so, the return spring can also be removed.
- Max pressure 350 bar, max force 1.7 metric tons
- Two G 1/4 ports for clamping and two for unclamping
- Metal plug to close extra ports
- Push spring (for single acting operation)
Another model is equipped with rotation stop pins so that the piston can not rotate. This requires some extra height so the total height is then 66 mm. This module HA-1SR1 is shown in the photo.
( The dotted line shows the standard model height 50 mm )
