Hydraulic Cylinders — Rod-Locking Device

The Hänchen Ratio-Clamp® 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.” 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. The Hänchen Rod Clamping Device meets the OSHA CFR 1910.217(d)(9)(iv) and ANSI B11.1-2001 standards for preventing the movement of the dies when adjustments and repairs are preformed or when humans are under the dies. This is an excellent alternative to safety blocks as it allows the flexibility to hold the die anywhere in its stroke and also immediately stops and holds the dies for an emergency or power loss.

Hänchen is a supplier and hydraulic cylinder manufacturer for various applications including construction, mechanical, technological, and industrial.

Hydraulic Cylinders — Standard Cylinders

Everyone who has heard of Hänchen is aware that its worldwide reputation is based on hydraulic cylinder solutions that are anything but standardized. The standardization actually deals with nothing more than basic dimensions and connections, mounting, parts, etc. Indeed for the common solution, a standard cylinder will often do the job without any problems. In many demanding applications it is possible to use a standard Hänchen cylinder due to the high quality levels they attain. In principle, they make exclusive use of honed cylinder tubes for all their cylinders. Hänchen also guarantees that all the cylinders in its product range, as well as normalized cylinders, comply with the most exacting of geometrical accuracies. Hans Holland Hydraulik offers a standard range with particularly cost-effective solutions. Whether you require newly-manufactured components or the additional machining of existing items, you can be sure their production facilities will meet your individual needs. Hans Holland Hydraulik also offers you preservation and color treatments. Also short delivery times, even of large batches of items, are no problem. Their standard cylinders often require only simple modifications to fulfill a wide range of applications, without the greater expense of full customization.
