Hydraulics

Applications of mobile hydraulic systems play an important role in truck transport, mainly in relation to loading and unloading goods - liquid, gas, loose unpacked and packed materials.

Hydraulika 1Hydraulic circuits task is to mediate transmission of pressure or torsional moment from source to appliance. The source is a hydrogenerator usually connected with gear box, engine or clutch of the vehicle. Then the appliance is usually a hydraulic piston or hydroengine. Hydroengines are driven by various types of aggregates. They can be pumps, compressors, blowers, vacuocompressors, reels.

The advantage of hydraulics is large flexibility allowing the transmission of torsional moment to places where it would be difficult or even unfeasible by any other mechanical way.

Basic overview of applications of common mobile hydraulic systems:

  • Tipping: one-, two- and three-sided tippers with different amount and placement of hydraulic cylinders
  • Hydraulic drives of pumping and compressor technology for filling and emptying truck tanks.
  • Hydraulic drives of special extensions - cranes, hydraulic arms, walking floors, loading machines of containers, autohoists etc.

Hydraulika 2The basis of a mobile hydraulic system is a tooth, lamellar or piston hydrogenerator. It is mostly driven from vehicle gearbox with the help of so called PTO (Power-Take-Off , in Czech pomocný nebo nezávislý pohon). PTO is an additional gearbox of various shapes and structures which is connected to the main box. It has an independent pneumatic, electropneumatic or electromagnetic control from the driver´s cab.

The basic PTO function is the drive of all mobile application by mechanical way (kardan shaft) or hydraulic way from the gearbox of the vehicle. ALFIMEX offers PTOs for all existing gearboxes of utility cars.

For the correct choice of PTO it is always necessary to specify:
- Type of application
- Type of vehicle
- Type of gearbox
- Required performance
- Required engine revolutions
- Type of output (kardan shaft carrier, pump attachment etc.)
- Placement (variations are possible with some gearboxes)


Hydraulika 3ALFIMEX will recommend and deliver the model which best meets your requirements. ALFIMEX is also a supplier of special gearboxes, so called dividing boxes. These special transmissions allow use of rear drive of the vehicle for drive of other extensional devices eg. electric current generator (mobile workshops, welding…), compressor (earthwork, pneuservice…), high-pressure pump (sewer system cleaning…), autohoists etc.

According to performance, effectiveness and time of load it is necessary to cool the circuits adequately and conduct the arising heat away. For this purpose modern coolers are used. Cooler in the most perfect version (Hydrapak - Hydromax) links effective cooling, filtration and protection against maximum excess pressure (safety valve, possibly thermostatic - or electric run-up - fan drive).

Company ALFIMEX, specialized supplier of mobile compressor and pumping technologies, also supplies high quality hydraulic components which will be appreciated by all extensioners who engage in this branch.

Hydraulika 4ALFIMEX solves the essential traders´ requirement - to allow goods transport from the seller to the buyer quickly, in a high quality, safely and comfortably - in a complex way by use of the most modern technologies. Company ALFIMEX s.r.o. is a distributor and service of this technology in the Czech Republic and Slovakia. In the next part of the catalogue you will find a brief cross-section of products and components which we offer to extension producers and to other distributors including spare parts.
