As you probably are aware, a hydraulic\u00a0ram\u00a0is\u00a0used\u00a0to\u00a0convert\u00a0oil\u00a0flow\u00a0into\u00a0powered\u00a0linear movement, in either one direction (single-acting ram), or two directions (double-acting ram).<\/p>\n
A double-acting ram provides powered linear movement in two opposing directions, like the ram on a shear grab for example, which uses hydraulic power to both open and close the grab.<\/p>\n
A double acting hydraulic ram has two internal rooms, one for providing power in each direction. There are some internal seals which prevent the oil from passing from one room to the other. When these seals fail, the oil moves between the rooms, causing unwanted linear movement in the ram. This can often be seen on an attachment like a front end loader.<\/p>\n
If you leave the loader in a raised position for a period of time, it will slowly start to slide down. This\u00a0is\u00a0generally\u00a0caused\u00a0by\u00a0oil escaping from one internal room to the other due to worn or damaged internal seals.<\/p>\n
Changing the seals isn\u2019t a difficult job once you understand a bit about the internal works of the cylinder.<\/p>\n
You will need to fully remove the ram from its working position to take it apart, so make sure of the ram is not supporting any weight or load that will suddenly move\/change as you remove the connecting pins.<\/p>\n
Health and Safety<\/strong>: Remember to never work under an unsupported load or object and keep safety in mind at all times and have someone working with you and conduct a quick risk assessment before you begin. Make sure you have all the right tools that you will need for the job as well to avoid accidents to yourself and to prevent damaging the cylinder.<\/p>\n It is also a good idea to place each component on a soft clean surface whilst removing and inspecting. This is so that you can avoid damage from surrounding debris and dirt, because although the parts can withstand high pressure, they are also easily damaged. In addition, you may wish to create a diagram of the parts so that it is easy to reassemble afterwards.<\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n Important: Even the smallest imperfection of the seals can cause the hydraulic ram to leak oil. So be absolutely certain that there is no damage to them before reseating them. If in doubt it is always best to replace.<\/p>\n <\/p>\n To reassemble the ram, simply reverse the steps. If parts need replacing, please contact us as we can supply the highest quality seals for your machinery.<\/p>\n <\/p>\n After reassembling the ram, return it into its working position, connect the hydraulic hoses and you’re back in action.<\/p>\n <\/p>\n If you discover that your hydraulic ram has damage to any of the components, please give us a call, as we can repair even the most badly damaged hydraulic cylinders.<\/p>\n","protected":false},"excerpt":{"rendered":" Hydraulic Ram Repairs Self Inspection Guide This article is aimed at the agricultural industry as a self help guide to farmers on inspecting their hydraulic rams to see if seals need replacing or whether the cylinder needs repairing.
