Hydraulic Press Products — Rod Locking Device

The Hänchen Ratio-Clamp® keeps the position for you. This device is a positive rod clamping safety device. The Ratio-Clamp is unlocked by hydraulic pressure. In the event of an electrical/hydraulic power loss, the potential energy of the internal Bellville washers load a conical piston, driving it over the friction fingers resulting in securing the load. “A true self contained safety clamp.”

Wherever power failures or malfunctions pose a risk to the safety of people or machinery, the rod locking device is there to save the day. It is also useful to accurately hold the cylinder rod in an exact position without the need to keep hydraulic pressure on the cylinder, thereby saving energy while maintaining accuracy. It clamps down and fixes the piston rod right where it is with no additional power needed.

Guaranteed advantages of hydraulic rod locks

  • No axial rod movement during clamping and releasing
  • Protective clamping effect in case of a power failure
  • Load capacity that is independent of direction
  • Clamps completely surrounding rods
  • IoT 4.0 Compatible: Integrated sensors to know if the clamp is locked or unlocked

Boasting a retention force of up to 101,000 lbf., the clamp hydraulically holds the piston rod in whatever position it is in at that particular moment without having to generate extra power (no extra energy) for an unlimited period of time. The clamping device Ratio-Clamp is approved by the German Technical Inspection Agency (TÜV).

Special development of Custom solutions (larger rod diameters, intermediate size, greater clamping forces) pose no problem for the Hänchen specialists. Hänchen is particularly proud of its RC-H model. Following a request from the Health and Safety Centre of the Employers’ Liability Association (BGZ iron and metal section III, Düsseldorf), Hänchen developed the new safety clamping hydraulic Ratio-Clamp under extreme conditions for use with hydraulic presses and injection molding machines.

Ratio-Clamp Applications

  • Testing technology in aviation: The setups for aviation tests have been refined to the last detail. Cylinders are used in different fields of testing, simulating ambient conditions and loads during different flight phases. The Ratio-Clamp® is used to protect the intricately constructed and expensive systems.
  • Production in molding and injection presses: Clamping units ensure safety during the pressing process in molding and injection presses for the production of synthetic and rubber molder parts in accordance with EN 289.
  • Maintenance in railway technology: During maintenance, trains must be fixed in a raised state. The Ratio-Clamp® is ideally suited for this purpose, as it holds the train securely in position until the work had been completed.
  • Production in grinding machines: During the production process of ICE rail sleepers, extremely large and heavy concrete workpieces must be positioned for grinding safely and with an accuracy of 0.01 mm. Hänchen’s hydraulic cylinders and Ratio- Clamp® clamping units are designed exactly for these requirements.
  • Production in profilling machines: Hänchen clamping units ensure precise machining and consistent quality in the production of metal profiles. During the production process, they facilitate the machining of the profiles by locking the forming tools in place. Ecological and efficient, purely with spring power.

POWER UNIT PRODUCTS & VALVES — CHECK VALVES

Power Unit Products & Valves – Check Valves

Check valves block an oil flow in one direction and allow it in the other direction. They are a type of shutoff valve.  The check valve is inserted when an oil flow shall be allowed in one direction only. Meanwhile, the usage of check valves prevents backflow of the fluid.

Advantages at a Glance:

  • Patented Spherical Shell
  • Available as Screw-In or Caged Version
  • Nominal Size 1/16-1/8-1/4-3/8-1/2-3/4
  • Working Pressure 10,000 PSI
  • BSP or Metric Thread

The HYTORC-check valves are available with a screw-in or caged design. Even so, both designs can be obtained in two flow directions: with the screw-in direction closed or with free-flow. The spherical cap remains reliably tight in every position, in case of multiple switching cycles and under severe stress.

The HYTORC check valve easily screws into a regular hole (Dimensions screw-in drill). The screw-in check valves are sealed through an edge sealing which is turned to the cage. The edge sealing, together with the drill draft, forms a gap-free chamber for the O-Ring. The gap-free chamber and the O-Ring are repeatable sealing.

The valve is made of a high-strength hardened steel. Moreover, the ball seat is specially treated and the patented spherical shell is manufactured with a high tensile hardened and polished ball bearing ball. Thus, the design of the check valves is compact and economical which saves space and offers simple installation.

Power Unit Products & Valves – Rubber Compensators

The Hydrower rubber compensators are elastic pipe joint couplings with rotating SAE and DIN flanges. The compensators are designed to absorb vibrations (noise reduction) as well as axial and radial stress.

Design:
The surface of the rubber compensators is smooth on the in- and outside incorporating two-fold high strength plies of fabric. The outer rubber, made of Neoprene, is weather resistant and protects the inner pressure bearer from ageing, wear and corrosion. The inner rubber is made of nitrile rubber (Perbunan, a Buna variety). The compensators have rubber reinforcements vulcanised on both sides. These reinforcements have two lips and an inclined ridge for better sealing. Further sealings are not necessary.

POWER UNIT PRODUCTS & VALVES — SHUT OFF VALVES

Power Unit Products & Valves – Shut Off Valves

The Hytorc shut off valves are mainly conceived for installation into pump suction pipes. The basis line has a SAE-connection shape with connection dimensions according to SAE-standard J518 – 3000 psi. After loosening the pipeline or the elastic pipe connection the shut off valve remains fixed to the part to be closed by fixing screws in the SAE-connection shape.

The inner diameter of the shut off valve is enlarged by the plate and threshold level diameter so that the free cross section complies to the nominal width. The plate and the threshold are formed to avoid a spin of the oil stream. A bolt which automatically snaps in any switch position guarantees arrestoring in any switch position. The bolt snaps into the switch plate which is fixed in a way that it cannot be lost, so that the shut off valve is always arrestored even without shifter.

Various additional flanges and parts make direct boltening to the oil tank (T-flange) or the installation into a pipeline (tapped bushings) possible. Due to the lateral openings (Ø 0) it is possible to fix the shut off valve between flanges or heavy (long) suction pipes can be held by additional screws. The shut off valves can be equipped with a limit switch, which is operated through the unloosable switch plate which is fixed so that it cannot be lost. Explosion-proof limit switches are possible.

Hydraulic Accessory — Butterfly Valves

The Hytorc butterfly valve is a component designed to save time for the technician working on the hydraulic system by not having to drain the reservoir. The valve is designed for low pressure hydraulic lines up to 230 psi and can be installed into the pump suction line or mounted directly on to the hydraulic reservoir for example. The maximum pressure differential on either side of the valve should not exceed 58 psi when the valve is closed.

Furthermore, when equipped with a limit switch, the operator can remotely see the open or closed status of the valve. Also, the thin profile and SAE flange makes it easy to design into the hydraulic circuit. The valve can be actuated with or without the shift handle and locked in to place with the automatic locking bolt. Available options: Reservoir Flange, Limit Switch and Threaded Adapter Bushing Inserts.
