Falling suspended load! If a load is transported by two cranes with a tandem control system, there is a risk that a breakdown of one crane will not be detected immediately. The diagonal pull could cause the load to fall, killing or injuring people. Only use lifting tackle or load lifting attachments where the load will not fall in the event of diagonal pull. |
In order to sling a joint load, switch tandem operation on first, then sling the joint load in individual operation (control one crane and block the other), then transport the load using both cranes in tandem operation.
Select lifting tackle or
load lifting attachments which will hold the load safely even in the event of
strong diagonal pull.
Activate tandem operation
at the transmitter.
See the radio remote control product manual.
Select one of the two
cranes for individual operation on the transmitter.
Move the load hook to the
required position in individual operation.
Attach the lifting tackle
or load lifting attachments safely to the load and hook.
Select the other crane for
individual operation on the transmitter.
Move the load hook to the
required position in individual operation.
Attach the lifting tackle
or load lifting attachments safely to the load and hook.
Select tandem operation
for both cranes on the transmitter and lift the load.
