A technological innovation

During the descent the force of gravity is sufficient for bring down the
whole accessory equipment. The energy of this force can be stored for reuse it during the boom mounting afterward.

Eco-nergy fonctionnement

How it works

At the first use or when the accumulator is empty the hydraulic circuit works normally. The pump provides the power to the two cylinders. During the descent of the boom by his own weight, the oil is recovered from the piston side chamber of cylinder to charge the accumulator by the potential energy of descent.

Finally, while boom mounting, the accumulator reproduces the energy needed to resist the weight of the boom and of the accessory equipment, so the hydraulic pump is used only to lift the payload. The energy gain is important then and it allows the using of engine which is twice more powerful.

When the boom is lifting the system works. The pressure is always depending on the work, the working distance and the weight of the accessory equipment.
