The system with two transmitter units.

REMdevice’s new remote control for safe and precise use on all makes of building cranes.

REMdevice radiocomandi radio remote control

With the option of operating the machine in use when the main transmitter unit is at a distance.

Allows normal operation of the machine if the main transmitter is out of order.

Reduces breakdown costs because professional on-site servicing is not necessary.

Avoids the installation of a cable command system.

The system with two transmitter units.

The TWIN SYSTEM includes two transmitter units (PAIL or BRICK models) and one receiver unit that is connected to the machine in use.

How the system works:
When the machine to be used is switched on, power is also supplied to the receiver connected to it and this is programmed to accept control from the first transmitter activated.

Once the receiver unit accepts control from one of the transmitter units, it then activates the machine in use to emit one of the following:

  • ONE acoustic signal if the principle transmitter is in control;
  • THREE acoustic signals if the auxiliary transmitter is in control.

From this moment until power to the receiver unit is cut off, the machine being used will be controlled exclusively by this transmitter. The other transmitter can NEVER take over control of the machine.

The TWIN SYSTEM complies with all relevant safety regulations currently in force;
the TWIN SYSTEM cannot be operated by two transmitters at the same time!

In order to transfer control of the machine from one transmitter to the other the machine in use must be turned off or the RELEASE command must be sent from the linked transmitter in use.
