Here is some information on using dual hydraulic side links and some other good question.
Frequently Asked Questions
1. What is a double-piloted check valve? A double-piloted check valve locks a cylinder in place and prevents any movement due to by-pass (up too 600 PSI) from the valve and will also give you a level of safety if a hose was to fail.
2. Why does CCM sell hydraulic toplinks with check valves? Safety first is the main reason. OSHA and the EU require piloted check valves as a safety on agricultural and industrial equipment when an object is lifted with a hydraulic cylinder and has no mechanical safety catch.
3. What size cylinder bore do I need on a hydraulic toplink? The working hydraulic press of most CAT 1 tractors ranges between 2200 3000 PSI. If you have a 2 hydraulic cylinder you will have the direct straight force of 5000-7000 LBS. If you use larger hydraulic cylinders then you risk exerting forces beyond the normal designed capacity of the tractor. CAT 1 tractors usually are not designed to lift more than 3000 Lbs with their 3-point lift. We do have larger hydraulic cylinders for CAT 2 applications.
4. I do not see a cylinder with the exact same stroke as my OEM toplink. You need to get a cylinder that will match the range of motion you normally use. If your OEM toplink is 18-32 likely an 18-26.5 hydraulic toplink will cover most of your applications. Most operations require use only of the first 60% of the OEM toplink.
5. Do I need both a hydraulic toplink & hydraulic sidelink? NO Customers with both a hydraulic toplink and a hydraulic sidelink adjust only the toplink 80% of the time and if they adjust the side link do so only once. The sidelink is beneficial to commercial landscapers that use a sidelink to adjust a boxblade for the desired contour.
6.
Can I use 2 hydraulic sidelinks? We do not recommend use of 2 hydraulic sidelinks. If you are doing this so you can exert down pressure it is not a good idea to do this. Most 3-point systems are not designed for the added down pressure force and will prematurely fail and cause unsafe situations with the added down force.
7. Where can I find other operators using hydraulic toplinks and Top and Tilt systems?
