Actual output torque

The starting torque is taken to be approximately 85% of the first value for available pressure. For a precise calculation, consult your Poclain Hydraulics application engineer.

The service life of the components is influenced by the pressure.You must check that the combination of forces applied (Axial load / Radial load) is compatible with the permissible loads for the components, and that the resulting service lives of these components complies with the application's specifications. For an accurate calculation, consult your Poclain Hydraulics application engineer.

Hydraulic connections

Take care over the immediate environment of the connections.

For other chassis mounting possibilities, please consult your Poclain Hydraulics engineer.

To find the connections’ tightening torques, see the brochure “Installation guide” N° 801478197L.

You are strongly advised to use the fluids specified in brochure “Installation guide” N° 801478197L.

Do not put either a check valve or a poppet valve on the pilot line.

BRAKES DYNA+™ Brake

Brake operationThis mutli-disk brake operates in two distinct ways:• Either by an absence of pressure (static braking): The spring applies a force to the static piston that is transmitted to the dynamic piston,

which clamps the fixed and free disks, preventing the shaft from turning. Braking torque decreases linearly as a function of unlocking pressure.

• Or by braking pressure (dynamic braking). The braking command creates a pressure on the dynamic braking piston, which clamps the fixed and free disks, preventing the shaft from turning. Braking torque increases linearly as a function of the unlocking pressure.

Brake release pressure vented.

Do not use both dynamic and parking brake simultaneously.

The use of certain oils, can not offer the characteristics ones above. Consult your Poclain Hydraulics sales engineer.
