Safety Guideline
1. The assembly instructions must be read and understood before set-up or
operation. The crane may only be assembled in accordance with the
manufacturer’s instruction manual. The manufacturer’s technical specifications
and limits must be adhered to all times and in no way exceeded.
2. The Traveler Crane may only be set-up or operated by trained and experienced
personnel. To avoid misuse by untrained personnel, the crane should be
dismantled when not in use or under supervision.
3. The crane may not be assembled or operated under influence of alcohol, drugs or
any other intoxicating substances.
4. The manufacturer accepts no liability for damages or injuries for incidents or
accidents occurring due to negligence by the crane operator, misuse of the crane
or disregarding the instruction manual.
5. The camera crane shall be used on the even terrain. If it is used on an uneven
terrain, it is not allowed to use the dolly, and the solution is to adjust the tripod to
maintain level.
6. After setup of the crane, the pan & tilt remote head shall be positioned under the
central pivot section when it is left unattended in assembled state, and if the pan &
tilt remote head is higher than the central pivot section, there should be someone
to look after the crane system.
7. Make sure that there is no wire with electric power which has higher voltage than
safety level within movement range of the whole crane system.
8. Be sure to avoid abruptly swiveling or stopping the crane, otherwise it may cause
falling of crane.
9. It is not allowed to use the crane under the environment with wind speed faster
than 5.5～7.9meter/per second.
10. When the camera crane is used in a rainy day, the pan & tilt remote head and
controlling bar shall be protected against rain.
11. Avoid anybody standing under the crane.
12. No loose objects may be stored or placed on the crane.
13. Before the counterweights are removed from counterweight rod, ensure the remote
head is resting on the ground or alternatively supported by an appropriate stable
underlay. Gradually remove the counterweights before the remote head, camera or
other parts are removed.
14. Make sure the location where the crane is installed can support the overall weight
of the crane (including the counterweight), and the special attention shall be given
when it is set up on roof and aerial construction.
15. When the control system is working, it is not allowed to turn the gear of the remote
head. If it needs to be adjusted, power supply should be switched off.
16. In the interest of safe crane operation, abrupt or sudden movement of the crane
should be avoided.
17. Only original accessories manufactured by Secced may be used with the crane.

Balance should be adjusted after the camera is installed. If camera uses battery to supply power,
the battery should be installed before adjusting balance. First of all, release the gear of tilt motor;
put the DV camera on the camera plate, use the screw to fix it. Then adjust the positions of the plate
backward or forward according to which way the camera turns, adjust balancing frame upward or
downward according to which way the camera turns, and repeatedly adjust the positions of plate
and balancing frame to ensure the camera doesn’t move anymore when turning to any position.
