• In case of interruption of the pneumatic or hydraulic supply, the
inverter of the suction unit remains in the same position it was when the
failure occurred.
4.8
Pump mounting - drive connection
• For the machines of this series, the allowed power transmissions
are:
Direct transmission (e.g.: from agricultural cardan shaft)
Oil hydraulic transmission (HYD).
• Protect with a fixed or interlocked guard and signal with
pictograms the power transmission chosen and applied by the final
installer, if there is the possibility that the operator will come into
contact during handling.
A) Cardan shaft drive
• Use telescopic cardan shafts.
Pic. 4.4
• In order to achieve a uniform motion of the driven shaft, the
following requirements must be met (see Pic. 4.4):
Equal working angle α and α1 of both couplings;
The internal fork joints must be coplanar;
Both driven and driving shafts must be coplanar.
• It is also recommended working with limited articulated joint angles
(max 15°) and disengaging the transmission for those operations
requiring great angles (steering or lifting).
Follow the rotation direction as indicated on the
pump front conveyor protection. Follow the
instructions of the cardan shaft’s manufacture.
• Use the cardan guard supplied with the pump, by fixing it to the
pump itself.
Use the cardan guard supplied with the pump, by
fixing it to the pump itself. In any case, the
installation, by the final installer, must comply
with the current EC accident prevention
regulations and must be compatible with the
geometry of the protection cap supplied with the
machine.
• The protection must not be removed; in case of removal, it is the
responsibility of the final installer to provide for suitable guards
according to the assembly.
• It is the responsibility of the final installer to provide for suitable
guards, in presence of transmission shafts exposed during normal
operation.
B) Belt drive
Pic. 4.5
• Do not apply pulleys on the cylindrical shaft of the decompressor.
Use pulleys supplied by JUROP which are fitted directly on the conical
shaft of the rotor.
• Do not apply excessive belt tension: use pulleys with a primitive
diameter equal to or greater than that recommended. Do not exceed
the permitted belt tension.
• If a pulley diameter other than those available is required, contact
JUROP Customer Service.
• Provide belt guards in compliance with current accident prevention
regulations that do not prevent ventilation and cooling.
