Performance
The energy stored by the lowering of the equipment in
the ERC System gives the machine additional perfor-
mance capacity. This is re leased again when the equip-
ment is raised, and is also reflected in more powerful
and more homogenous work sequences. The result is a
clear sav ing on fuel – and, at the same time, even greater
performance.
Economy
The ERC System supports the equipment when lifting.
This means that engine speeds can be lower, while at the
same time smaller lifting cylinders can be fitted. That in
turn substantially reduces the machine’s fuel consump-
tion, and leads to even greater economy.
As well as this, pollution and noise emission are percep-
tibly reduced. This helps safeguard the environment and
saves energy resources.
ERCSystem–Moreperformance,lessconsumption
The principle is simple: As the equipment fitting is lowered, this causes the gas present in the cylinder to be compressed. When the attach-
ment fitting is raised, the energy stored in the gas cylinder provides support for the two lifting cylinders, and less performance is required.
1. Attachment fitting raised /
Energy released
2. Lower attachment fitting / Store energy
4. Raise attachment fitting / Release energy 3. Attachment fitting lowered /
