LBT frequency search

When switching on or switching to another frequency, the system checks whether the frequency channel used is occupied by other transmitters. If this is the case, the next frequency channel is checked until it is ensured that the transmitter can operate without interference. LBT is the abbreviation for ‘Listen before Talk’.

The smallest model in the new PocketEvo® range has 6 buttons, which can have 1, 2 or 3 levels as well as stepless, depending on customer requirements. In addition, the integration of various additional operating elements such as rotary switches and side buttons is possible without any problems. This makes the PocketEvo® minor suitable for more complex applications in addition to crane control.

Thanks to the patented SMP technology, all installed keys can be easily replaced by operators themselves. Without special tools, each button can be unscrewed individually and a new one inserted. However, the robust special housing remains closed at all times, so that no protective measures against soiling have to be taken. This means that the system is fully operational again in just a few minutes and downtimes are reduced to a minimum!

We have developed our own special housing for optimum protection against dirt and impact. The integrated, all-round protective rubber coating in combination with the glass fibre reinforced plastic core ensures that all electronic components can withstand extreme external mechanical influences. This means that the PocketEvo® can be used in particularly harsh environments without any problems.

Should a transmitter become damaged, you can connect the new device to the receiver and put it into operation in just a few minutes thanks to the integrated Radiokey. The key is removed from the device with the help of a screwdriver and inserted into the new one – your system is ready for operation again and expensive downtimes are avoided.

The jury of the Industry Prize was also convinced by the radio remote control, so that they awarded the PocketEvo® the “Industry Prize 2017”. The prize is awarded to particularly progressive industrial products that have a high economic, technological and ecological benefit. The PocketEvo® was awarded the “BEST OF” rating.

Compact, handy and easy to use, the PocketEvo® button transmitter allows you to work in complete safety conditions without reducing the effectiveness of machine operation.

The Surface Mounted Push-Buttons (SMP) are form-fit integrated into the PocketEvo® series housings. In the event of service, the operator can easily replace a broken button himself on site. The housing does not have to be opened for this purpose, so no protective measures against soiling need to be taken. [More info]

Multi-user system

The multi-user system enables radio communication between several transmitters and several receivers. Each transmitter can be optionally operated with several receivers at a workplace and / or vice versa. Provided that this connection is not otherwise used at this moment.

NBB battery system

Nickel metal hydride batteries (NiMH) have a high energy density. The contacts have a self-cleaning design. The NBB battery pack is charged with a high charge current with a NBB charger. This quick charge is thermally controlled to optimize recharging and prevent overcharging.


The safety risk is significantly reduced using the RADIOKEY. Here a defined range is available for the crane or machine operator in which the remote control system can be activated. As a result, unwitting or inadvertent activation of the transmitter is excluded and the receiver is not sent any control information.

LBT frequency search

When switching on or when switching the frequency, a check is carried out to determine whether the used frequency channel is reserved by another transmitter. If this is the case, the next frequency channel is checked until it is ensured that the transmitter can operate without disturbance. LBT is shortcut for Listen before Talk.
