The Federal Government's "Digitalpakt Schule" initiative grants financial assistance of EUR 5 billion to the federal states from a special “digital infrastructure” fund. This fund is designed to help the federal states and municipalities make nationally significant investments in local education infrastructure. The federal states contribute at least 10 percent to the investments financed with federal funds. Each federal state grants the applications of the school boards and monitors the implementation of the projects.

When the hydraulic trainers were designed, the noise level was a special consideration. The system comes with a frequency-controlled unit and has a sound pressure level of 46 to 50 dBA (1 meter distance). This means you can have a conversation without any problems if the trainer is switched on.

• The integrated power units of the hydraulic trainers are compatible with a normal socket (Schuko) (1x 230 V, 50 Hz). Therefore, no three-phase connection is required. Other versions and other voltages are available; please contact us for further information. You can find more information in our HHT2 hydraulic trainer product catalogue.
   
• On the other hand, the power unit for mobile training requires three phases (3x 400 V, 50 Hz), a CEE 400 V 16 A socket is required. See product catalogue: Load Sensing.

The hydraulic trainer’s power unit provides 3.7 l/min per workstation. The operating pressure for the exercises is 0 to 60 bar. The pressure level is limited to 70 bar. You can find more information in our HHT2 hydraulic trainer product catalogue.

The hydraulic trainer’s tank has a capacity of 20 litres. Clean oil ISO VG 32 (hydraulic oil according to DIN 51524 T1 + T2, viscosity range 32 mm²/s at 40°C oil temperature) is used to fill the tank. For more information and start-up instructions, please refer to hydraulic trainer operating instructions.

Specially designed brackets are used to attach components to the profile wall. The assembly and disassembly of the valves is carried out without tools. The components can be freely positioned on the profile wall using the fastening system.

The hydraulic trainer is movable. It is fitted with four polyamide swivel casters.

Yes. You can push the trainer through normal doors without any problems. See dimensions.

The hydraulic trainer has a weight of 465 kg.
Dimensions: 2090 mm x 780 mm x 1774 mm (L x W x H)

You do not have to acquire all the versions and components. There are different designs and configuration levels. The system is modular and can be upgraded and adjusted to meet your training needs. Contact us for further information.

A wide range of upgrade options are available. The components were divided into the following categories:

• Standard hydraulics with manual operation
• Electro-hydraulic valves
• Relay switch box
• Programmable logic controller
• Proportional technology
• Digital package 4.0
• Mobile control blocks (open/closed-centre)
• Load-sensing unit
• Various function modules

You can find more details in our product catalogue.

We recommend three people per workstation. Six people can be trained with our trainer which has two workstations.

Our trainers with two workstations permit different exercises and circuits at each workstation. Both sides function independently for the majority of the exercises. Each team can work at its own pace.

We developed a large number of training exercises for the hydraulic trainers. The tasks are grouped and available as a PDF file. There is a version for students and a version for teachers. The training exercises are exclusively available as a PDF when purchasing a hydraulic trainer!

Extract from the hydraulic trainer exercises:
 

• The terms pressure, area and force
• Transmission of force
• Flow rate as a hydraulic parameter
• Relationship between velocity, pressure and volume rate
• Hydraulic cylinder (master/slave cylinder, simultaneous motion, stop positions and "tracking")
• Velocity control with throttle valves or supply control
• Electrical piloting of valves
• Latching circuit for 4/3-directional valves
• Differences between monostable and bistable valves
• Working with time delays
• Realising cyclic processes
• Structure of PLC programs
• Use of SR elements in PLC programs
• Control of 4/2 and 4/3 directional valves
• Different control modes of mono/bistable valves
• Realising different speeds
• Sequential controls
• Integration of sensors (proximity switches / pressure switches)
• Use of timers

In addition to training tasks, we also supply reference books. You can of course also buy the textbooks from us without attending a seminar or purchasing the hydraulic trainer. You can find an extract on our website.

If you do not need the hydraulic trainer on a regular basis or perhaps only once, we can gladly provide you with a hydraulic trainer as a rental unit. The equipment delivered with the rental device is determined according to your requirements.

The hydraulic trainer comes in different versions. The standard hydraulics package features manual operation of the valves with a lever. The electrohydraulic package operates the valves with solenoids and an electric circuit. The student learns how to wire the valve and can use switches or a PLC to create the required movements.
