Hydraulic Cylinders

Custom cylinders are offered by both Hans Holland and Hänchen. The Hans Holland cylinder manufacturing company offers high quality hydraulic cylinder solutions for an economic price. The Company has been in business for over 65 years. Large bore cylinders can be designed, built and delivered in a timely manner. Modifications can be made to the standard series cylinders to satisfy a broader area of application without incurring high costs of custom manufacturing. Our engineers are available to help with your specialty cylinder application.

Specialty cylinders are offered by both Hans Holland and Hänchen. Hänchen has been renown for top quality hydraulic cylinders for many years. The company's strengths lie within it's superior engineering group that has been developing and producing innovative technical solutions for a wide variety of applications.

The product line consists of special cylinders for water hydraulics manufactured from stainless steel and non magnetic materials, high tech cushioning technology and low friction cylinders.

Hänchen offers compensating valves integrated in the piston, metering cylinders, three-position cylinders, rapid force/speed cylinders, high speed cylinders (up to 40 m/s), multi-position cylinders, plunger cylinders, control and servo-cylinders, synchronous cylinders, tandem cylinders, telescopic cylinders, cooling jacket cylinders, hollow piston cylinders, oscillation (fatigue rated) cylinders, locking and tensioning cylinders. Hänchen provides solutions for the most demanding application.

Hänchen Specialty 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. As far as Hänchen is concerned, there is no reason to look to another quality standard other than its own for its standard cylinders. In other words, they benefit from the company's quality aspirations. In principle, Hänchen makes exclusive use of honed cylinder tubes for all its 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.

Hänchen Standard Series Cylinders

The Hanchen 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 Hanchen specialists.

Hanchen 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 Hanchen 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.
