Operator Safety Instructions
Ø
Before beginning crane operation, position yourself so that you have a clear and complete
overview of the working radius of the crane or machine.
Ø
Depending on your angle or position to the crane or machine, the transmitter control commands
“trolley left” and “trolley right” appear to interchange! It is essential that you take your
bearings to the crane or machine into due consideration before operating equipment.
Ø
In case of an emergency or any disturbances within the working range of the crane or machine,
switch the transmitter off immediately by actuating the STOP switch. Should the transmitter
show signs of technical failure or breakdown, disconnect the radio system immediately !
Ø
Always switch OFF the transmitter during breaks and after finishing work to avoid operating
errors or any accidental actuation of operator control elements.
–
These precautions are particularly important whenever changing your position or climbing
over an obstacle.
Ø
Never leave an activated transmitter unattended. The operator undertakes to follow and comply
with the authoritative regulations for worker safety and accident prevention (e. g. VBG 9).
Note :
In the event of an interruption of the radio link during a working cycle – what can occasionally
happen – both transmitter and receiver automatically shut down (so-called
"compulsory switch-
off"
).
To reactivate the system the you must release all operator controls, such as pushbuttons or momentary
contacts, and allow the control elements to return to their zero position. Reactivate the radio system by
pressing the "ON/OFF" toggle switch. The system must be reactivated before the crane or machine can
react to control commands ! This feature hinders any uncontrolled or unwanted crane or machine
movement, should the radio link be interrupted.
When operating a crane by means of a radio telecontrol system for the first time, you may miss
the physical contact to the crane that you were used to in the operating stand. As you are no
longer in the crane and can no longer sense the starting of the crane movements as distinctly,
crane reactions appear sluggish or dull.
