Servo Power Pack
Servo Power Pack with torque control for shorter cycle times and maximum efficiency. Thanks to the water-cooled servo solution, we precisely control torque and pressure based on the end product, resulting in faster response times and higher energy efficiency.

Servo Power Pack
In a production environment where short cycle times and consistent product quality are critical, a conventional hydraulic drive system no longer met the expectations. The customer was looking for a solution that could:
Switch and respond faster
Operate more energy-efficiently under variable load
Remain stable and repeatable during critical movements
Provide better control of torque and pressure, depending on the end product
AHP Hydraulics developed and integrated a Servo Power Pack with intelligent control, designed for optimal performance and lower operating costs.
Key features of the project:
Water-cooled servo motor & pump
Torque control adapted to the end product (torque regulation based on the process)
Optimized response and reaction times through smart system configuration
Full integration into machine control and automation (monitoring & tuning)
Thanks to the Servo Power Pack, the customer achieved measurable improvements:
✅ Shorter cycle times
✅ Higher power efficiency (energy efficiency)
✅ Improved process control through torque-based regulation
✅ More stable end-product quality and less variation in production
✅ More efficient hydraulic power usage — only when needed
Where is this applied?
This solution is ideal for machines and processes with variable load or high dynamics, such as:
Presses and forming applications
Test benches and force-controlled setups
Assembly and production lines
Cyclic movements requiring high repeatability
Motion control: 4 axis ball joint tester
SIDEM NV needed a more accurate and flexible ball joint endurance tester. AHP Hydraulics rebuilt the complete test bench and delivered a 4-axis servo-controlled system with real-time compensation for reliable asynchronous testing

Motion control: 4 axis ball joint tester
SIDEM NV needed a highly accurate and flexible endurance test bench for ball joints. AHP Hydraulics fully rebuilt the machine — hydraulics, electrical and software — to guarantee stable results even in complex multi-axis testing.
SIDEM required a tester that could:
✅ Maintain high accuracy in force and angular motion
✅ Run synchronous and asynchronous test cycles
✅ Stay stable under dynamic and long-term endurance loads
✅ Be user-friendly and deliver reliable test data output
A complete redevelopment of the existing tester:
Test bench rebuilt from mechanical base frame
New hydraulic, electrical and software architecture
Designed as a future-proof validation platform
Key performance specs
4-axis endurance testing (4 DOF):
Axial force + radial displacement
Independent control per axis:
Sinusoidal profiles (0–4 Hz) per axis
Supports synchronous & asynchronous operation
Test range:
Force amplitude: 0–6000 N
Angular rotation: ±30° (axis z) / ±45° (axis y) radial
Key technology features
Servo-hydraulic force control (±100 N accuracy)
Servo motor rotation control (±0.5° accuracy)
Real-time compensation software for asynchronous testing
Live HMI scope visualisation + automatic CSV export
Key takeaways / results:
✅ Accurate and repeatable test results — even in asynchronous setups
✅ Stable endurance testing across a wide operating range
✅ Faster setup thanks to easy centring for multiple workpiece types
✅ Full traceable test data for analysis and reporting
✅ A robust, modern test bench ready for long-term validation programs
Ideal for
Ball joint & suspension component testing
Durability / lifetime endurance validation
Multi-axis servo-hydraulic test benches

Retrofit baling press
"Retrofitting a baling press built in 1996 so that it meets the requirements to press efficiently high-quality material today". AHP received this assignment from an established player in the recycling industry. Mechanical construction, electrical wiring, electrical cabinets and automation were all carried out in-house.
The press was operated manually, with several unpleasant interventions by the operator, such as turning the carousel, unlocking and locking the chamber doors, opening/closing the carousel lock, etc. Also, the pressed bale had to be manually pushed out of the chamber at the end of the process. The combination of such manual actions created physical discomfort and potentially unsafe situations for the operator.
Today, through mechanical construction modifications, the addition of a lot of sensors and machine control, the baling cycle runs automatically and the operator's actions are reduced to strapping the bale and replacing the packaging material.
Moreover, it has also been ensured that the production process is controllable by parameters. By doing this, things like bale height, press pressure, number of fills, etc. can be modified.
In addition, the software also offers added value in terms of production monitoring. A register of the last 20 bale heights, a bale counter (day & total) and the production time of the last bale are visualised on the HMI (Human Machine Interface).

Retrofitting gantry crane
The gantry crane was operated manually by levers on the PVG (Proportional Valve Group) block in the wheelhouse. The wheelhouse of the gantry crane has only one small window.

Retrofitting gantry crane
The gantry crane was operated manually by levers on the PVG (Proportional Valve Group) block in the wheelhouse. The wheelhouse of the gantry crane has only one small window. As a result, the operator's view during operation is very limited, which not only caused discomfort in use but also affected overall safety. In order to eliminate the existing shortcomings, a remote control was integrated. This allows the gantry crane to be controlled wirelessly, which means that the operator no longer needs to operate it from the wheelhouse. Since the operator can now move around while operating the gantry crane, work can be done faster, more accurately and more safely. The adjustments provide increased user-friendliness and safety.
Furthermore, the existing controls of the gantry crane were very outdated. They were therefore replaced during this project. The electrical installation was completely renewed and a new PVG block was mounted, allowing manual operation to continue.
Levelling system for mobile hopper scale
The Robbe Bascules mobile hopper scale is a discontinuous totalising weighing installation. By making the installation mobile, the customer has the opportunity to easily move the hopper scale so that it can be positioned at the quay as well as in the warehouse.

Levelling system for mobile hopper scale
The Robbe Bascules mobile hopper scale is a discontinuous totalising weighing installation. By making the installation mobile, the customer has the opportunity to easily move the hopper scale so that it can be positioned at the quay as well as in the warehouse. In order to achieve an accurate and correct measurement, the implementation of a solid levelling system is essential.
On the frame of the weighing installation AHP Hydraulics placed a hydraulic group and PVG (proportional valve group) with electrification and software implementation. The hopper scale is levelled by means of 4 hydraulic cylinders. The cylinders lift the hopper scale and ensure that it is levelled. The cylinders are hydraulically controlled by a Danfoss PVG. The proportional valves of the PVG receive the electrical command (PWM) from a Danfoss PLUS+1 controller (MC050). In addition, each cylinder is equipped with 2 pressure sensors Danfoss MBS1250 (on the rod and piston side) so that the weight distribution can be monitored and controlled. Based on the measured value of an inclination sensor (Danfoss DST X730), a closed loop control was developed which proportionally adjusts the 4 cylinders.
