Locking units are capable of retaining forces in both axial directions. They are used in a wide variety of machines. In most versions the clamping is spring actuated, and hydraulic or pneumatic pressure is required to release it. Shaft diameters range from 10 to 250 mm. The respective holding forces vary from 0.1 to 1000 kN, depending on style and customer requirements.
If the device is used as a restraint device and emergency brake in machine tools, a special version KFHW is available. For this reason, all the external parts and sealing surfaces are made of stainless steel.

At the very latest when, because of a power failure (intentional or not) or a malfunction something has to be done to safeguard man and machine, hydraulic clamp Ratio-Clamp® - the clamping device from Hänchen - is just what you need.
Boasting a retention force of up to 450 kN, the hydraulic clamp holds the piston rod in whatever position it is in at that particular moment. Without having to rustle up some extra power (no extra energy) and for an unlimited period of time. The clamping device Ratio-Clamp® is approved by the German Technical Inspection Agency (TÜV). Nor does the development of specific solutions (larger rod diameters, intermediate sizes, greater clamping forces…) pose a problem to the Hänchen specialists.
The possibilities for your application:
Rod-Ø from 10 - 140 mm,
clamping forces from
1 - 450 kN. Other
dimensions on request.

- Hydraulic cylinders
- Test cylinders
- Complete system solutions (Ratio-Drive®)

Safety Locks similar to Safety Catchers and Safety Brakes are used against failure of lifting members. But in contrast to those they are not suitable to decelerate masses or to dissipate kinetic energy. On the other hand, the rod displacement to build up the holding force is very small, so that this units can be used for a approximitive positioning tasks as well. Furthermore this design principle allows compact solutions even for small rod sizes (smaller than for Safety Catchers). In the field of pneumatic clamping devices the Safety Locks are providing the absolutely highest holding forces in relation to housing dimensions.

Active without pressure – incredible holding force
The pneumatic Clamping and Braking Element for piston rods RB.
The RB series is based on our proven wedge slide gear principle and is used for clamping and braking without pressure.
This element was developed for deployment on round-shaft guides or piston rods with a surface hardness of min. HCR 54.
The compact design is suitable for shaft diameters of Ø10 to Ø60 and allows holding forces of up to 60,000 N at a pneumatic opening pressure of just 4 bar.
As a specific feature no reset is needed for restarting.
The RB series stands out for its short reaction times. Even in vertical deployment, short braking distance are achieved in less than 30 ms

Low-profile clamps come in two basic models, one with a single-wedge and the other with a double-wedge construction. In addition, we offer a line of machinable jaw models for workpieces of irregular shape and a special model for casting and wire EDM applications
Standard models come with a hardness of 48-52 HRC and the jaws are serrated or smooth, depending on model. Both the wedge and the jaws are made of tool steel and are through hardened. Fastening operation involving one bolt (M5-16) ensures quick set up times.

The Alpha A-Pod was borne out of the Job Shop market where set ups were always changing and having a dedicated magnetic chuck on one machine was not practical. The A-Pods provided greater flexibility and quicker pay back. Due to the A-Pod's flexibility, customers began to discover other uses for the A-Pods.
The A-Pod is an ideal tool for the creative shop owner, so Tool and Die shops began using the magnets in place of hydraulic fixtures because magnets cost less, are more flexible and require virtually no maintenance. Unlike a chuck, the A-Pod is completely modular and has little impact to a machine's table weight capacity. A set of A-Pods can be shared between multiple machines.
Large plate manufacturer's discovered the benefits of the A-Pods over conventional magnetic chucks, because A-Pods provide sufficient clamping force and greater flexibility for less money and with significantly less weight.

Horizontal Zeropoint Quickclamping cylinder with piston-catching
Hydraulic release
Cover and piston hardened
Repeat accuracy < 0,005 mm
Size: K20, K40
Explanation:
With our new Zeropoint Quickclamping cylinder with piston-catching, we make the palletizing asier and quicker.
• No search of drilling
• No damage of zero point drilling and nipples
• No risk of injury
Releasing and taking out of the pallet, take place still faster and simpler, because of the linking with the crane which is not more necessary during the release phase
Thanks to the speed of pelletizing, you reduce considerably your pelletizing period and consequently your costs.
Advantages:
• With and without blow out
• Completely in stainless steel
• Applicable in all positions without fit-up aids
• When the mechanism is out of service, the piston-catching stay out, it can be locked, thus the discs spring are not forced.
