WEO Plug-In WEO Swivels WEO Cartridge

 

 


Just Plug It In! -The WEO Plug-In system

AS SIMPLE AS IT SOUNDS. The WEO fitting is a smart plug-in solution from CEJN offering extensive problem-solving features and cost savings. This self-aligning plug-in fitting enables quick and safe hydraulic hose kit assembly without any tools. For even better adaptation to customer applications, we offer the core of our design – the WEO cartridge, for a fully-integrated, compact design, and our reinforced two-in-one WEO plug-in swivel, for swivelling applications at full working pressure.

 

 

WEO PLUG-IN COUPLING

Stay flexible
If you are looking for a compact coupling solution but still want to keep your existing manifold design, you don’t have to worry. The WEO Plug-In coupling offers a multitude of thread or tube connections and, as no tools are needed for hose assembly, you can still focus on compact design.

 

WEO PLUG-IN CARTRIDGE

Integrate
At the core of our design you will find the WEO Cartridge, a refined component made for compact system integration. Its slim size opens up new design possibilities. As no adapter is needed, costs are reduced and at the same time one potential leakage point is eliminated. Reduce the footprint of your final design and enjoy extensive cost savings.

 

WEO PLUG-IN SWIVEL

Swivel under full pressure
The ideal solution for applications with pressurized moving and rotating hydraulic hoses is the WEO swivel. The WEO Plug-In swivel can rotate 360° while under full working pressure and includes a combined ball and slide bearing, accommodating both hydraulic and torsion forces, resulting in significantly increased service life for your products. WEO Swivel is both a swivel and a plug-in fitting and is as small and flexible as the basic version of WEO Plug-In, giving you a size and weight advantage over commonly-used swivel solutions.

 

 

WEO PLUG-IN NIPPLE

Quick connection
WEO is designed with an innovative push-to-connect feature that provides quick and quality-assured engagement of the product´s male and female halves. The only time you need a tool is to remove the assembly stop when disconnecting, and this can be done with a screwdriver or similar. Once the assembly stop is removed, you simply push the male nipple all the way in and pull it out from the female component.

 


Screw Fittings vs WEO Plug-In

 

Under or over torque
Torque values are based on calculations and comprehensive testing and getting these values right on the assembly line requires precision. Personnel need to be well trained, have calibrated tooling and be able to access the components to be assembled, which are often difficult to reach and tighten. All of this often leads to over or under torque during assembly. The result is leakage during final testing or later on when the product is delivered to a customer. This leads to costly re-working and claims. All these problems can be solved with WEO, as you just plug in.

Embedded tension from torque
When applying torque to screw fittings there is a big risk of embedded tension in the hoses. As strained hoses are subject to pressure impulses, hose movement and even rotation during operation, the lifetime of any such hose is dramatically reduced, resulting in premature failure and leakage. Premature hose failure frequently leads to warranty claims and can be very costly. With the self-aligning WEO Plug-In, such hose and leakage problems are solved, and with the WEO Swivel, extreme hose movement and full rotation under pressure are no problem at all.

WEO helps you avoid leakage from torque and hose failure due to embedded tension!

 


WEO Plug-In Coupling - For quick and safe assembly

WEO Plug-In Coupling

WITH THIS APPLICATION SAFETY IS THE MAJOR FOCUS. In the confined space between chassis and cabin, the operator has to carry out hose connection with a heavy cabin hovering over his head – a very exposed situation. Users of screw-connect fittings always have the challenge of achieving correct torque. Imagine performing this task with no room at all for tools. In many cases this results in leakage from couplings and embedded tension in hoses that subsequently leads to leakage. With WEO you can work quickly and avoid leakage problems, since all you have to do is plug in.

 

  • SAVE TIME
    The fact that all you have to do is plug in means a considerable reduction in assembly time.
  • HEALTH & SAFETY
    No torque processes in confined spaces that could cause personal injury. Exposure is minimised thanks to a quick assembly process. Good ergonomics – you just plug in and thus avoid awkward postures that can cause strain.
  • MINIMISE LEAKAGE
    With WEO, no torque process is required and leakage problems are avoided – just plug in.
  • EXTENDED HOSE LIFE
    With our self-aligning WEO, hoses last longer. No embedded tension to wear them out.

  2. The nipple is securely locked with the unique WEO locking hooks.
  3. Using a screwdriver, remove the assembly stop.
  4. Push the nipple all the way in and then pull it firmly out.

 


WEO Plug-In Cartridge - For integrated and compact design

WEO-Application-Cartridge-CEJN

WE ARE ALWAYS ON THE LOOK-OUT FOR SMARTER SOLUTIONS. With its minimal space requirements, the WEO cartridge allows designers to design new compact hydraulic systems. When incorporating this compact cartridge into your design, you can minimize the footprint of the final design by reducing the space between the ports. This means less material required and reduced costs.  Again, since our fittings simply plug in, you don’t have to worry about hand-tool clearance, unlike traditional screw fittings where extra clearance for tools is required when tightening.

 

MINIMISE LEAKAGE
No torque, no leakage – just plug in.

SUPER COMPACT
By integrating the WEO cartridge into your design, you can minimize the footprint thanks to its compact size. In addition, no tools are needed during hose assembly.

SAVE TIME
The fact that all you have to do is plug in means a considerable reduction in assembly time.

EXTENDED HOSE LIFE
With our self-aligning WEO, hoses last longer. No embedded tension to wear them out.

HEALTH & SAFETY
No torque processes in confined spaces that could cause personal injury. Good ergonomics – you just plug in and thus avoid awkward postures that can cause strain.

WEO Plug-In Swivel – For extreme swivelling applications

CEJN WEO Plug-In Swivel

EXTENDED HOSE LIFE
With our self-aligning WEO, hoses last longer. No embedded tension to wear them out.

SAVE TIME
The fact that all you have to do is plug in means a considerable reduction in assembly time.

HEALTH & SAFETY
No torque processes in confined spaces that could cause personal injury. Exposure is minimised thanks to a quick assembly process. Good ergonomics – you just plug in and thus avoid awkward postures that can cause strain.

MINIMISE LEAKAGE
WEO Plug-In Swivel eliminates problems with unscrewing and embedded tension in hoses and can handle extreme hose movement and rotation.

WHEN IT COMES TO APPLICATIONS WITH EXTREME HOSE MOVEMENT, the obvious solution is the WEO Swivel.  A truck-mounted crane causes the hoses on the valve blocks to twist and rotate in a way that causes them to wear out. When using the WEO swivel, the hoses can move freely and self-align, with 360-degree rotation under full working pressure. The result is longer hose service life and fewer claims.

FASSI: ”Our vision is to have the WEO Plug-In on all our machines”

Crane manufacturer FASSI choose WEO Swivel


When CEJN came into contact with FASSI, they were suffering leakage, quality and dimension problems with their current connections on hydraulic control valves. There were also delivery problems with the connections, causing frustration. In applications like this, when hoses are constantly being twisted, a good swivel function is a must to enable long hose life.  With the WEO swivel, FASSI immediately saw these benefits together with the advantage of fewer components, meaning a reduced number of leakage points. Leakage was often due to difficulty in assembling the different parts in narrow spaces. Another appealing feature was the plug-in system, which would cut the assembly time considerably.

 

FASSI has now been using the WEO swivel for over two years and they are very satisfied, especially with the reduced number of components, meaning fewer connection points to cause problems and leaks. The time savings are very important as well: “With WEO we can connect without the need for tools and it is extremely quick. When assembling, we save at least ten minutes on every crane,” states Roberto.

WEO is currently being used on the distributor bank of small and medium-sized cranes and when we ask Roberto about the future for WEO, he feels that the next step is to implement the WEO plug-in on the large models too: “For me, the fast assembly time is the most important aspect. My vision is to have the WEO plug-in on all our machines. Always WEO”, explains Roberto.

Reduce overall costs with WEO

On the drawing board
The designer has scope to create more compact and smarter designs with our small and flexible WEO solutions. Designs that will reduce both size and costs.

On the assembly line
If you are working on improving the efficiency of your assembly line, you will first become aware of the time you save. Plus the possibility of making mistakes is eliminated. With a simple plug-in, the connection is achieved without any complicated torque calculations. You often also need to fit a torque wrench into narrow spaces where application of torque is impossible. With WEO, the job is done in no time. It can reduce the time for final testing, as WEO is a Poka-yoke solution.

The machine owner
As an owner of a WEO-equipped machine, you will save both time and money. Instances of twisted hoses that burst due to rotation will be minimised and countless hours will be saved thanks to simplified disassembly.
