LOAD SENSING means extremely high efficiency and cost-effectiveness for PALFINGER cranes

For the consistent further development of its products, PALFINGER cooperates not only with numerous research establishments but also with supply and assembly companies in order to bring products to the market which meet the requirements of operating practice, make the work of users easier and increase the efficiency of operations.

Equipment of the control block with a load-sensing proportional valve
In combination with PALFINGER radio remote control the load-sensing proportional valve permits very sensitive control. The efficiency and cost-effectiveness of crane deployment depend not only on the crane itself but on the vehicle and the drive system. PALFINGER lays the foundation for the economic operation of the total system by providing the requisite equipment on its cranes: Through the equipment of the control block with a load-sensing proportional valve PALFINGER cranes are ready for cost-efficient variable displacement pump operation. Compared with a fixed displacement pump, which always supplies the crane with the same quantity of oil, the variable displacement or load-sensing pump delivers only the quantity that is actually needed for the particular crane function.

Owing to the variable displacement volume of the pump, it is possible to adjust the volume flow to the requirements of all connected consumers. In contrast to a fixed displacement pump, no surplus volume flow is produced which has to be drained off to the tank. Output is always adjusted to actual consumption and the energy consumption is therefore optimised.

With LOAD SENSING crane work will in future be 
- even more efficient and economical and have the 
- potential through variable displacement pump operation to reduce fuel consumption by up
to 20 %, while also offering 
- increased fine-controllability and a 
- longer service life for the loading crane.


The advantages are clear
Lower fuel consumption, better fine and multiple controllability and less load on the entire hydraulic system because the oil does not heat up as much!
Fuel savings of up to 20% and a very short payback time for the higher purchase costs reflect the cost-efficiency of variable displacement pump operation. And the reduced loading results in an increased service life for the crane. Thanks to the regulated oil supply, the crane can be more sensitively controlled and the load can be positioned more precisely. Without having to intervene in the system the operator can work much more precisely, quickly and therefore cost-efficiently – advantages which pay off in particular in assembly work.
