Options

Stationary Transmitter
When the circumstances do not allow for the use of a portable transmitter, a stationary one can be implemented, e.g. if the operator can only operate from the control console in his crane or another vehicle, the stationary transmitter is of great use.

Data transmission from machine to machine or the interlocking system of a conveyor belt is another good example of further application areas.

Changing the RF-Channel
In order to ensure interference-free operation of a radio control system it may be necessary to change the RF-channel locally.

Changing the RF-channel can become necessary due to interference or the fact that a specific RF-channel is already in use. A change of channel can be performed either by reprogramming the TransKey or by reprogramming the transmitter. Reprogramming of the transmitter is performed using the transmitter keypad and requires no additional equipment.

Pitch and Catch
In the case of a pitch and catch operation, the crane can be controlled alternatively via two transmitters. One transmitter assumes responsibility for commands via an active request command. Only by an active release command is the crane given free and the other operator is able to have access to the crane again.

This option is the soloution when different operators at various locations in the area and have to transport loads across large distances.

Electronic Deadman Control
The electronic deadman control shall prevent an unintentional use of a joystick, which can cause unwanted movement of cranes or machines.

The operator has to release the joystick by putting it back to the neutral position before giving the ultimate command. Without this release the joystick will not react and no commands will be conveyed from transmitter to receiver.

After the release, the joystick remains active until it returns to the neutral position and remains there for set amount of time. The active/inactive status of the joystick is indicated by a LED on the transmitter.

This feature can be set for a drive, a joystick or even two joysticks.

Man-down Alert
As operation of a remote control always requires the operator to be in an upright position, the transmitter has a tilt sensor which monitors whether the transmitter and thus also the operator are in an upright position.

If the transmitter or the operator are no longer in an upright position, a warning signal will sound after a brief period; this warns that the transmitter is in a tilted position. Unless the transmitter is not returned to an upright position or a certain button is not pressed in order to extend the tilt period, the crane or machine is automatically brought to a standstill by a forced braking.

Infrared Start-up Feature
The infrared start-up feature for radio remote controls is a safety feature. The radio remote control can only be activated if the transmitter is within the vicinity and in view of the receiver. This ensures unintentional crane or machine activation.
