Hydrostatic steeringType LAG

Hydrostatic steering

Steering units

• The LAG steering unit for hydraulic steering is the main elementfor steering all types of machines. Due to the purely hydraulicforce transmission, it is possible to connect the steering unit tothe steering axial via hoses which, even with difficultinstallations, can easily be achieved.

• The steering unit works to the rotary spool principle• The LAG is a hydraulic force steering aid which also, if the

energy supply fails, makes the steering function possible with ahigher hand force (emergency operation).

• Areas of application:Tractors, self-propelled agricultural and forestry machines,municipal machines, rollers, wheel loaders, mobile excavators,cranes, graders, mining machines, ships and fork lifts

• Our programme also includes priority valves and steeringcolumns which are matched to the steering units.

Type LAG

Steering unit - LAG

Displacement volumes 50, 63, 80, 100, 125, 160, 200, 250, 320, 400, 500 and 630 cm3

Versions:

LAGC steering unit with integrated safety valvesDesigns: – ON-open-center-non-reaction

– OR-open-center-reaction– LS-load-sensing-non-reaction– LS-load-sensing-reactionThe LAGC steering unit contains all of the valves which are required toprovide safety functions for the steering unit and steering cylinder; thisalso eliminates any additional pipework.

LAGU steering unit with reduction ratio

Designs: – LS-load-sensing non-reaction– LS-load-sensing reactionThe steering unit with reduction ratio utilises a dosage pump. In emergencyoperation (when the energy supply fails) the displacement is reduced byswitching-off chambers. The remaining displacment volume makes it possiblewith the same hand force to achieve a higher pressure. It is, thereforepossible in many cases to eliminate the emergency steering pump.

The LAGU steering unit also contains all of the valves which are requiredto provide safety functions for the steering circuit.

Micro-controllers (MC) are the basic building block for flexiblesystem solutions. Standardised technology, unified plug connectorsand robust sealed housings make it possible to select the optimumhardware to suit the scope of the requirements.

Deciding features are:• Powerful, highly integrated microprocessors• Programme memory, flash EPROM and data memory EEPROM

for application specific modifications• Real time operating system for extensive programming• Safety functions, e.g. watch dog, redundancy and central

switching off of all of the outputs• Input and outputs with cable brake recognision and short circuit

monitoring• Proportional outputs, pulse width modulated and current

controlled• RS232 interface for parameterisation and diagnostics as well as

a CAN bus for net working more than one micro-controller

Software• Software packages for differing system applications are prepared

with an optimum programme structure and can, with very littleeffort, be matched to meet specific customer requirements.

• Universal software is used for standardised applications withouthaving to carry out any development work.

Gears for stationary applications

• REDULUS planetary gears assume a multitude of tasks inindustrial systems. Due to their compact design they help saveweight and space. High transmission torques, high transmissionratios, and, in spite of standardisation, a variety of mountingconfigurations for the input and output sides offer the rightsolution for a multitude of drive problems.

• Complete with a hydrualic motor, the HYDRODRIVE GMH shaft-mounted drives can be used in all applications, where lowspeeds are required with good true running characteristics.

Couplings for diesel motor drives

Highly flexible couplings dampen, e.g. in ship drive systems,uncontrolled rotary vibrations that can occur when passingthrough critical speeds. Their elastic elements prevent damagebeing caused to valuable drive systems. The same elements arefitted to highly flexible switching couplings, that additionally permitthe drive train to be switched on or off. These couplings are alsosuitable for use with PTO/PTI drives.
