bauma 2025 is set to be the largest edition of the international show dedicated to the construction and mining industries. Over 3,500 exhibitors will be highlighting their latest technologies, services and machines over 614,000 sq. m of exhibition space — which includes both indoor and outdoor displays.
Two halls on the show grounds will be dedicated to hydraulics and related power transmission technologies; several hydraulics companies will be located in other parts of show as well.
Hydraulics remain an important component of construction and mining equipment. Major industry trends such as electrification, automation and digitalization are influencing new developments in hydraulics. Technological developments related to these trends and many others will be on display at bauma which takes place April 7-13 in Munich.
Following is a look at just a handful of the many hydraulic related technologies that will be on display during bauma 2025.
Bosch Rexroth Introducing Software and Hardware Solutions to Aid Efficiency, Automation and More
Bosch Rexroth plans to show new software and hardware solutions to aid with automation, electrification, connectivity and efficiency in construction and other mobile equipment. Among these will be new hydraulic technologies from the company as well as HydraForce which it acquired in 2023.
To help simplify engineering, the new BODAS Studio development tool will be introduced. Based on a standardized, open software architecture with a wide range of integration options such as MATLAB and Simulink from MathWorks, it is designed to save time when generating code. This can help engineers of all skill levels to develop systems faster.
The company will also introduce a new Collision Avoidance System (CAS) to ensure the safe operation of autonomous machines. It uses a combination of radar, ultrasound and smart cameras to detect objects and people; a warning signal is sent to machine operators if there is a chance of collision and if no action is taken by operators the system decelerates the vehicle and eventually employs emergency brakes which typically use hydraulics.
Hydraulics technology introductions will include the enhanced EMP motor-generator series and the new compact MPR Performance Radial piston motor for small machines as it is designed to save valuable installation space, weight and energy. Compared to the MCR3 from Bosch Rexroth, the new MPR motor design saves around 25% in components and up to 30% in length.
New Compact Hydraulics from HydraForce and Bosch Rexroth
The acquisition of HydraForce by Bosch Rexroth led to the creation of the Compact Hydraulics Business Unit which brings together both companies’ expertise in developing compact hydraulic components and systems.
At bauma, there will be live demonstrations of these various technologies. Newer hydraulic solutions from this segment of the business will be exhibited as well including:
- Load Holding Valves — compact, energy-efficient valves designed to optimize load management, reduce wear and enhance operational stability.
- H- and E-Valve ranges — for 3-50 ton excavators, the H-valve improves fuel efficiency by minimizing pressure drops while the E-valve range introduces electronic control for precise movements and reduced cycle times.
- EHBL Digital Boom Control Valve and HF-Impulse 2.0 — an electro-proportional relief solution that offers exceptional flow capacity (up to 454 lpm) and reduced energy consumption. It can be used with the HF-Impulse 2.0 software tool to ease programming of machine controllers.
- EDG-OBE Piloted Compact Directional Valves — features integrated electronics to provide high precision and reliability for applications like aerial platforms, forklifts and agricultural cranes which require a high level of safety and control.
- Oil Condition Sensor Developed with Tan Delta Systems — provides real-time monitoring of oil quality to aid proactive maintenance of hydraulic systems.
HAWE Adds More Safety to Hydraulic Technologies
At bauma 2025, HAWE Hydraulik will show several of its control, automation and electrification solutions. Among these will be a new pump controller for electrified drives and smart tools to enable the safe control of hydraulic valves.
Control blocks, under the theme ‘Customized compact controls’ will be a key focus of the company’s bauma exhibit. This will help the company highlight the different types of integrated control blocks it offers, many of which can be tailored to customers’ specific application needs.
Newer technologies on display will include the PSL-CAN EX directional spool valve with onboard electronics which is now approved for use in explosive environments. The valve’s actuating head has been redesigned to ensure compliance with regulations including ATEX, IECEx, MA and CCC.
MICK, the directional valve bank, is another new addition to HAWE’s portfolio that will be on display at bauma which uses the load-sensing principle of the company’s PSL spool valves. Per HAWE, the directional spool valve controls the volume flow steplessly and independently of the load. The integrated hydraulic safety circuit ensures that the three cylinder groups are separated from each other and prevents individual mast and support functions from being accidentally actuated at the same time helping to meet modern safety requirements in mobile machinery. It is particularly suited for use with boom and outrigger control in concrete pumps and spider platforms.

- Mobile Electrification — Electro-hydraulic pumps and electric motors are among the technologies Parker is developing to aid the electrification of mobile machinery and which will be on display at bauma.
The company’s booth will also include a presentation zone where it will offer product demonstrations, expert talks, and in-depth discussions with Parker engineers throughout the show.
Liebherr Exhibiting Next-Generation Hydraulic Cylinders
Liebherr-Components, the component division of Liebherr Group, is exhibiting the next generation of its hydraulic cylinders which the company said are designed to help meet increasing demand for sustainable, smart, high-performance machinery.
Sensors are integrated into the cylinders to provide real-time performance monitoring. This enables early detection of wear which could lead to eventual failures and thus unplanned downtime. Instead, machine operators can be more proactive about addressing issues that arise before they occur.
Use of carbon fiber reinforced plastic provides a lightweight design for the hydraulic cylinders. This can help reduce overall machine weight, leading to reduced emissions output as less energy is required to operate the equipment. It also allows for longer booms and more agile machine movements noted Liebherr.
Danfoss to Show Technologies Which Meet Sustainability and Other Industry Trends
At its bauma exhibit, Danfoss Power Solutions intends to show its range of products that can help create a more sustainable construction equipment industry. These will include highlighting the company’s capabilities in hydraulics, eHydraulics, electrification, digitalization, autonomy, and software — all of which can help to create more productive and efficient, and thus more sustainable, machines.
The company said its booth will feature over 60 products organized by the subsystems in which they are commonly used on heavy machinery: propel, steering, work function, and controls. Electrification and eHydraulics technologies will be exhibited as well, helping to demonstrate the range of solutions Danfoss offers and the continued integration of electric and hydraulic systems.
New products it will launch at the show include the X1P family of open-circuit piston pumps built, additions to the Thorx line of cam lobe motors, and a thermoplastic hose for material handling applications.
Poclain Unveiling New Generation of Hydraulic Motors
Poclain Hydraulics stated in its pre-bauma press release that the event will mark the introduction of a new wave of technologies from the company, including a new generation of hydraulic motors.
The new HEVO suite of hydraulic motors are designed to meet the needs of hydrostatic transmissions which the company said are still preferred in many market applications. HEVO is comprised of three core technologies: HEVO Booster, a local pressure amplifier; HEVO Dual Feed, a new oil distribution strategy; and HEVO Edge a new generation of hydraulic and mechanical sensors.
The first HEVO motors to be released to the market will be the HEVO Booster in the 20,000 and 6,000 Nm ranges, and the HEVO Dual in the 5,000-10,000 Nm segment. HEVO Booster is engineered for wheel-based applications facing high torque peaks and requiring controlled speeds; it provides up to 800 bar to improve efficiency.
Poclain explained that the motor operates on a small nominal displacement sufficient for more than 90% of its usage time. When torque peaks occur, an internal pressure booster activates, potentially doubling the pressure inside the main cylinder block up to 800 bar for a short duration. The company said HEVO Booster allows a machine, such as a compactor to use two 1.4 L displacement motors instead of the 2.8 L options available today while maintaining full functionality. This allows a reduction in hydraulic flow requirements and simplifies machine architecture, all of which can lead to 22% lower fuel consumption.
HEVO Dual is a two-displacement motor designed to run most of the time in its smaller displacement to maximize energy efficiency through high pressure and low flow conditions. It utilizes a new oil distribution strategy to handle high speed and high power for an extended period of time without overheating.
HEVO Edge is a smart sensor with local edge intelligence which integrated into the company’s new generation of hydraulic motors. Edge devices like this allow data processing to occur on or near a component, speeding up the time it takes to do so. And integrating the sensor in the motor ensures it is protected.
