Can one remote control drive more than one receiver?
Whether this is possible depends on the set's learning logic and is not stated in the product data; confirm with technical support before ordering. The alternative, directly applicable method is to share out the channels of a single receiver: on a 4-channel set CH1-CH2 drives the first mechanism and CH3-CH4 the second.
There are two solution paths.
1) Single receiver, channel sharing. If the mechanisms are close to each other this is the most robust method. On a 4-channel set two bidirectional motions, on a 6-channel set three bidirectional motions are managed independently. No extra pairing is needed, it works with a single supply and a single antenna.
2) Same remote control, more than one receiver. If the mechanisms are far apart, each gets its own receiver. In that case the same transmitter must be able to be paired to more than one receiver; whether this is supported is not stated in the product data, verify it from the user manual or technical support.
If this method is supported, there is a general behaviour to watch: every receiver whose identity has been paired can receive the same command while in range; that is, a CH1 command may pull in the same relay on more than one machine. Verify from technical support before purchase how this behaves on your set. If this is not wanted, the mechanisms must be spread across different channels or a separate remote control must be used per machine.
In both arrangements it is essential that the operator knows exactly which machine they are driving, that the channels are labelled on the machine, and that every machine has its own wired emergency stop circuit.
