Hystat have successfully supplied hydraulic cylinders to an array of marine industries since 1976. Within this time Hystat have typically dealt with large bespoke cylinders for large projects.

3 Hystat have successfully supplied hydraulic cylinders to an array of marine industries since Within this time Hystat have typically dealt with large bespoke cylinders for large projects. Over this period we have attained an excellent reputation for product quality and reliability. Due to demand we have implemented a standard range of both marine and offshore grade cylinders. All designs conform to Lloyds Register, DNV and ABS rules. Our experienced team of design engineers have the skills and expertise to develop professional and cost effective solutions to meet your requirements. Using the latest in 3D CAD software and utilising Finite Element Analysis to check for any possible failure scenarios prior to manufacture. Our in house machining capability means that we can turn up to 1.2m diameter and up to 8m in length. Our state of the art three, four and five axis CNC machines are able to produce complex components, such as bespoke manifold blocks in high quantities using the most efficient method. The benefits of using Hystat standard cylinders for your marine projects are a reputable product which guarantees quality, reliability and cost effectiveness. Whilst also offering highly certified products in larger volumes at much shorter lead times than our competitors.

7 BUCKLIN DIARAM Depending upon the particular application it may be necessary to assess the resistance of a cylinder to buckling under the forces applied. The graphs shown are intended to be used as a guide for normal applications where good alignment can be achieved. Special consideration should be given to unusual applications, and applications where shock loading may take place. Particularly if the cylinder is to be mounted in a horizontal position. i. Determine the force applied to the cylinder and the H value required. ii. If the intersection point is below the line of the desired rod size then buckling should not be a concern. (In some cases a smaller rod size could be considered). iii. If the intersection point is above the line of the desired rod size then buckling may be an issue. (Refer to the rod size above). Please note that the graphs shown are to be used as a guide only, for accurate application specific rod sizes please contact Hystat Safety Factor: Euler formula 3:1 Rankine formula 4:1 Modules of: E = Mpa elasticity Yield: 520 N/mm 2 nominal Push Force (kn) 50 Lk = H (PINNED PINNED) Buckling length Lk (m) Lk = 0.7 X H (PINNED FIXED) Push Force (kn) Lk = 0.5 X H (FIXED FIXED) Buckling length Lk (m) 4

BESPOKE MARINE CYLINDERS When choosing a Hydraulic Cylinder to suit your application it may not be possible to choose a design from our standard range.

16 BESPOKE MARINE CYLINDERS When choosing a Hydraulic Cylinder to suit your application it may not be possible to choose a design from our standard range. To aid with the design and reduce the time taken during the design process the following step by step guide can be used to determine an approximate length, bearing size, rod end profiles required etc. i. Choose a suitable bore & rod size based on the Theoretical Load Ratings table on page 3. Typical working load to be % of theoretical load ii. Determine a realistic body length by using the graph overleaf. Remember to add the stroke length onto the body length. iii. If the cylinder features a spherical rod end choose a suitable bearing type & size by using the data sheets on pages iv. Use the data sheets on pages to determine a suitable eye profile. If the cylinder is in compression, only the load rating of the bearing needs to be considered. Standard bearing sizes are shown in eye profiles. Alternative bearing sizes may be chosen to fit in existing profiles however do not exceed the standard size so not to lower the load rating of the eye. v. Ensure that the extended length of the cylinder with the chosen rod size is not subject to buckling. Refer to page 4. vi. Determine a suitable rod material based on working conditions. Use table on page 18 for reference. Sales shall advise on quotation POSITION FEEDBACK If position feedback is required please use the data sheet on page 25 for reference as to what we can offer. 13

17 BESPOKE MARINE CYLINDERS Once a bore size has been chosen, an approximate body length can be determined (x-axis). 600 BORE TO "L" RATIO 500 CYLINDER BORE (mm) SHORT BODY LENTH (SHORTER STROKES) LON BODY LENTH (LONER STROKES) "L" CYLINDER BODY LENTH (mm) The ideal scenario is that the body length falls below the Nominal line. FOR EXAMPLE: (Ø300mm bore cylinder would have a body length of 525mm + stroke). If the body length falls onto the minimum line or above, it does not mean the design is unachievable however it leaves less space for internals such as seals and bearing length. For example pneumatic or low pressure cylinders would tend to fall in to this category. FOR EXAMPLE: (Ø300mm bore cylinder would have a body length of 510mm or less+ stroke). If the cylinder falls onto the ultimate line or below this would suggest that either stop tubes may be needed due to a long stroke or that the cylinder features additional items such as a transducer. FOR EXAMPLE: (Ø300mm bore cylinder would have a body length of 560mm or more+ stroke). NOTE: The above table is to be used as a guide only, sizes may be subject to change upon receipt of order. 14
