Incotandem

Synchronisation of two cranes working in tandem

For situations where the same load is handled using 2 cranes, and we want effective synchronisation of their movements.

GH SOLUTION: INTERCONNECTED + TANDEM = INCOTANDEM

Tandem mode: This allows control of the movements of 2 cranes from 1 radio control.
There are 2 radio transmitters. Each transmitter can control a crane individually. And when the tandem mode is activated, one of the transmitters is capable of controlling the movements of the 2 cranes (it acts as the master).
Each crane is equipped with 1 receiver with two functions: communication with the transmitter operated by the user and communication with the receiver installed on the other crane.
If any of the movements (lifting, trolley movement, bridge movement) changes between slow speed/fast speed/stop, a signal is sent to the other crane to carry out the same change.
The transmitters can be push-button type (standard) or console (optional).

Easy to switch between tandem mode and individual mode. In the transmitter that can function as the master, there is a selector to choose individual mode or tandem mode.
Suitable for cranes with 1 or 2 trolleys each. Also for cranes with 1 trolley with 2 lifting systems.
Occupies fewer radio frequencies (only 3 frequencies per pair of cranes).
The number of pieces of equipment to install is reduced. The system does not need an additional transmitter-receiver set (fixed/fixed system).
Reduction of components and wiring simplifies installation, commissioning and maintenance.

1_ Release the crane that will work as a slave from its transmitter.
2_ Activate tandem mode on the master transmitter.
3_ Communication will be established automatically between the master transmitter and each of the receivers installed in the cranes.
4_ Two-way communication between the crane receivers will be established automatically.
5_ If any of the movements (lifting, trolley movement, bridge movement) changes between slow speed/fast speed/stop in one crane, a signal is sent to the other crane to carry out the same change.
