Project Description


NBB Radio retrofitting

Radio retrofitting

Thanks to the Radio retrofitting, lever-operated systems such as loading cranes can be retrofitted with a radio remote control. With this variant, up to 6 levers can be moved.

Alternatively, we also offer a retrofit system that can move up to 4 levers.

The integrated mechanical position control offers:

  • Suitable for high continuous loads at high working temperatures
  • High security standard
  • EMV safe due to missing electronic functions
  • Any installation positions

Possible variations

  • 4- or 6- functions
  • Connection to the existing hydraulic supply
  • Optional: Self-sufficient hydraulic supply by the electrical pump (12 V or 24 V)

Radio retrofitting for loading cranes with 4 or 6 functions

  • Radio remote control HyPro-6
  • Receiver Compact-V (antenna included)
  • 2 batteries 7.2 V 2.400 mAh
  • Charger with plug for cigarette lighter and car socket
  • Shoulder strap
  • Electro-hydraulic retrofitting module including fastening flags
  • Pressure reducing valve + filter for connecting the actuators to the crane’s oil circuit

The retrofitting kit consists of an add-on control module with 6/4 sections in order to serve the corresponding consumers.

This retrofit kit is designed to retrofit manual hydraulic systems with a low operating frequency with a radio remote control. It works proportionally and independently of the required actuation force. It is simply coupled with the existing manual operation of the machine.

With the servoblock retrofit system, NBB offers modern, safe, precise and completely safe use. To ensure your safety, Nbb expressly points out that the instructions in the manual must be understood before using the machine. Serious accidents can occur if the instructions are not followed. Radio controlled machines may only be operated by qualified and authorized persons. For safety reasons, the control should be kept in a closed cabin.

Invest in Radio retrofitting and benefit from the simple installation. Increase the ease of use and offer maximum safety for man and machine!


Teach-In function

The Teach-In adjustment feature allows for customized response for each joystick for optimum safety and performance. Several adjustments can be made to each individual motion such as min/max values and joystick deadband adjustment. [More Info]
