Radio Control System
3.2.2 Option "Pitch – Catch"
The "Pitch – Catch" operating mode
allows two or more crane operators
equipped with one transmitter each to
independently use the same crane
The crane is equipped with a radio
receiver that can receive and monitor
transmitter frequencies.
After activating the receiver all
transmitters have equal access to the
control system.
Releasing the crane ( "Pitch" )
To release the crane :
1. Enter the "pitch" command via the
rotary switch or pushbutton on
transmitter 1 or transmitter 2.
2. For safety reasons we recommend switching OFF transmitter 1 or transmitter 2. This
will avoid operator errors.
This cancels the access rights of transmitter 1 or transmitter 2 to the crane.
Taking over control of the crane ( "Catch" )
To take over the control of the crane, enter the "catch" command via the rotary switch or
pushbutton on transmitter 1 or transmitter 2.
The transmitter with control over the crane retains the access to the receiver
(transmitter 1 or transmitter 2) until the operator has issued the "Pitch" statement.
Operating Example :
Transmitter 2 has control over the crane control system. Transmitter 1 is to be given
control. The operators must continue as follows :
1. Enter the "pitch" command via the rotary switch or pushbutton on transmitter 2.
2. For safety reasons we recommend switching OFF transmitter 2, i.e. turn the key
switch to the "0 = OFF" position.
3. Activate transmitter 1, i.e. turn the key switch to the "1 = ON" position.
4. Enter the "catch" command via the rotary switch or pushbutton on transmitter 1.
Transmitter 1 now has sole access to all crane functions.
Notes :
– A power loss at the receiver-end activates a general reset of the crane system. All
transmitters have access to the crane radio controls. This implies that the pitch –
catch settings must be readjusted at the transmitter-end.
– Should an operator forget to issue the "pitch" statement and shuts down his
transmitter (transmitter shut down using the STOP pushbutton or technical failure)
the second transmitter has no access to the crane radio control system. In order to
give transmitter 2 access to the radio control system the receiver must be cut OFF
from the supply voltage (master switch) and the crane control system reactivated as
described above.
– The "pitch" and "catch" commands should therefore be laid on a rotary switch or a
pushbutton. In addition, a lamp that can be mounted on the crane will indicate when
the receiver is busy (busy display).
