Compose your configuration step by step.
Do you have an excavator, a tractor equipped with a crane or a forestry machine? Put together your Naarva assembly by choosing the mechanical and hydraulic connections adapted to your carrier and the desired equipment.
1. Start from your carrier machine
- On an excavator: the extension boom is mounted in place of the bucket; the Naarva equipment is then mounted as a pendulum.
- On a tractor or forestry machine with crane: pendulum mounting with rotator, 360º free rotation.
2. For excavator mounting: choose your extension boom and indicate your attachment type
- JPK23: 1,2 m extension reach, to assemble yourself, designed for our most compact and light models.
- New JP35 range: specially designed for the Naarva S35C.
- Basic model JP35, extension reach from 1,2 m to 1,6 m depending on the position of the attachment on the boom.
- Additional extensions as options:
- VP80: 80 cm fixed
- JPM35: 1,6 m manually adjustable
- JPH35: 1,6 m adjustable by hydraulic cylinder
- Fastener type available: S40, S45, S50 or S60, NTP10. Other fastener type on request.
- Shorter boom available on request.
3. Compose the mechanical connections
- Single brake swing damper: connect the boom to the rotator
- Rotator with shaft connection and a FR10 connection as standard. On request: other connection size and rotator with flange combined with Naarva quick couplers.
4. Adapt the hydraulic power supply
- The Naarva head: provide a power supply in accordance with the recommendations of the chosen model, 1/2″ hoses.
- The rotator: recommendation for the standard model: 20-30L/min, 210bar, 3/8″ hoses.
- JPH35 hydraulic boom: recommendation 50-70L/min, 210bar, 1/2″ hoses.
Are you lacking auxiliary circuits?
Electrically operated hydraulic selection is possible: depending on the configuration, a 6/2 selector switch allows a circuit to be shared between several functions. The 6/2 selector valve is available as standard on the JPH35 hydraulic boom. You can install the wiring between the valve and the driver’s cab yourself.
Prepare your assembly request.
To guide you to the right options, send your Naarva dealer:
- the model and size of your carrier machine, as well as the crane model if it has one. For excavators: type and dimensions of the carrier attachment.
- the desired Naarva machine and the work to be done.
- where applicable, the references and dimensions of the interfaces of the existing rotator.
- the number of auxiliary hydraulic circuits, their type of control, pressure, flow rate and hose diameter.
- the equipment you want to be able to switch between.
We will help you select the right mechanical and hydraulic connections.
The professional K32, E32 and EF28 models require a specific study: this guide is not applicable to them.
If your installation is not covered by an existing solution, an adaptation on request can be considered.
