Working with 700bar is not to be taken lightly. Therefore, always keep these ground rules in mind when working with high-pressure hydraulics:
Basic knowledge of Holmatro hydraulic tools;
Recommended total cylinder capacity
In connection with various uncertanties, we always recommend a system with sufficient extra capacity:
- The exact weight of the total load
- The spreading of the load among the cylinders
- Possible moving of the load in case of calamities
(F)orce of a cylinder = P X A
The force (capacity) generated by a cylinder is equal to the hydraulic pressure (P) multiplied by the effective pressure area (A) of the plunger.
Minimum effective tank volume of pump =
(oil volume of cylinder 1 + 2 + ....) x 1,2 (20%)
Required operating speed =
(oil volume of cylinders 1 + 2) ÷ pump output
DO YOU FEEL THE PRESSURE TO WORK SAFE? USE YOUR BRAIN!
Correct & periodic maintenance can prevent unnecessary damages, costs, and unsafe situations.
To make sure you are working safe with high-pressure hydraulics, have your tools regularly tested & serviced:
- At least once a year
- With use of dynamic testing
Holmatro’ s years of experience has learned there is only one correct way to determine if a hydraulic system is safe to use: dynamic testing. With dynamic testing, a max use situation of the cylinder is simulated in a controlled environment. By doing so, hidden defects will be identified sooner, ensuring the reliability, safety & lifespan of your tools.
- Specially for high pressure hydraulics > 500 bar
- 105% over pressure
Which items in your hydraulic system require periodic maintenance, in order to work safe?
Hydraulic pump-unit: the motor of your system; regulates the oil flow & working pressure in the system. To maintain safety in the hydraulic system, a pressure relief valve is indispensable.
- Hose: transport of oils from the hydraulic pump unit to the cylinder(s)
- Cylinder: your hydraulic tool to lift high tonnage, with a small surface
The whole hydraulic system functions under high pressure (> 500 bar). The system components may bare both visible and invisible malfunctions. Therefore, Holmatro believes in dynamic testing. Feel free to contact us for more info!
Want to learn more about working safely with hydraulics?
Unprofessional use of high-pressure hydraulic tools occurs on a regular basis. Our safety sheets list all the dos and don’ts for working with hydraulic lifting tools in a straightforward and conveniently organized manner. These are indispensable in every workplace where hydraulic tools are used.
Working with 720 bar (10.400 Psi) is not to be taken lightly. Aided by the Holmatro Test team risks of working with high-pressure hydraulics are demonstrated and explained in an easy, recognizable way.
A Toolbox Meeting is a periodic meeting intended to improve daily safety at work based on a specific topic. We offer various Toolbox Meetings for our lifting solutions, including the Holmatro high-pressure hydraulics. We help you understand the risks related to high-pressure hydraulics, with on- and offline tools. Not only to help keep your employees safe, but also meet your legal obligations.
