With larger developments in machinery design continuing to emerge, with the creation of components that are responsive to the demands of the construction industry.
Among the key goals for components, makers are hydraulic performance and developing electronic systems to improving machine precision and controllability and reduce fuel consumption. Translating this into a better-finished machine is often a combination of in-house design by the equipment manufacturer.
Hydraulic systems and components have evolved dramatically over the past several years. As engine ratings have dipped, hydraulic systems have become more “intelligent” with enhanced power and performance.
Due to regulation norms, many of today’s machinery are using less powerful engines than comparable of 10 years ago. For this generation of engines to maintain comparable performance specifications, the hydraulics systems have to be smarter and more efficient.
OEMs have emphasized designing equipment across global markets and product development is of core importance. Within its key areas of focus, yearly products are developing a response to the stringent emissions regulation that has seen engines developed to meet Stage V legislation.
For example, Hitachi has established a TRIAS hydraulics system, which three pumps and has been fitted to its series of excavators of between 20 and 35 tonnes.
This inclusion of the hydraulic hybrid system provides about 15% fuel savings in normal operating conditions, which can go up more if used in countries with higher fuel costs. It also helps reduce CO2 emissions by 12% because it is enabling more efficient fuel burn and the flow of oil in hydraulic circuits is more evenly, and therefore the machine is more responsive and precise and with power mode enabled for tougher jobs.
One of the major problems that manufacturers face is the contamination of hydraulic oils, which can cause a lot of other problems short of out-and-out equipment failure. It can cause equipment to be sluggish and inefficient, require more frequent maintenance, and ultimately have an impact on production that translates to the bottom line.
Particle contamination especially insidious is that the particles that pose the most risk are those that cannot be seen with the naked eye. In today’s precision equipment with extremely tight clearances, particles as small as one to 10 microns (millionths of a meter) can cause severe, performance-impairing damage.
Finding solutions to minimize the risk of damage by knowing and adhering to the equipment and component manufacturer’s specifications for oil cleanliness and using an oil certified to the ISO cleanliness code is highly recommended.
The global construction equipment hydraulic pump market is estimated at $XX Billion in 2022 and growing at XX% CAGR till 2030.
JCB Power Systems has developed a new range of EU Stage 5-compliant engines to power OEM equipment. The future of hydraulics is system integration and more efficient machine operation. Its new generation of servo-controlled hydrostatic pumps.
The H1 family of pumps brings intelligent incorporation of the propulsion drive into the machine management architecture and expands the functionality of the vehicle, across a wide range of potential application areas, including construction.
The new pumps feature common design technologies and assembly techniques. Overall, it has simpler, high-performance designs with fewer parts than previous hydrostatic products. Significant performance benefits include improved pump efficiency, which reduces unit power losses, and reduced noise levels.
Volvo-engineered Hydraulic Hybrid Assist System, a technology first introduced at bauma 2019, which uses a 100% boom Energy generated by the boom down motion is captured hydraulically and used to assist the boom up motion, where it needs most of the pressure and power.
