PRRKING BARRIER
1) Arm length can be chosen from 3M,4.5M and 5.5M. Beam falling time is also arranged from 1sec,3sec and 6sec.
2) Machine core with compression spring, effectively avoids the accidents caused by spring breaking
3) Die-casting aluminum alloy motor, precision and good at thermal radiating
4) Motor cooling fan, solving the problem of heat-protection
5) Double safety limit switches (photoelectricity limit switch/motor memory sensor)
6) Reversing on obstacle
7) Support the external and internal VEHICLE LOOP DETECTOR (optional)
8) Traffic light interface
9) Wire control (switch signal)/ Remote control (418MHZ)
10) RS485 communication module (optional)
Technical Description
The combination of our proven and reliable
electric motor with a lever system represents
a simple and extremely reliable drive solution.
It permits short opening and closing
times without the barrier boom bouncing in
the end positions. The lever system locks the
barrier boom at both end positions. In the
event of a power failure, it can still be moved
easily by hand.
The complete drive system is attached to the
barrier housing as a single unit, and can easily
be removed from the housing by removing
the mounting screws.
A built in spring mechanism provides a precise
counterbalance for the barrier boom.
The springs are factory set to correspond
with the boom length prior to delivery. If
necessary, the springs can be easily reset in
situ during assembly, for example if the barrier
boom is shortened or if signs are attached
to the boom.
It is also a simple matter to change the handing
on-site from right-axial to left-axial.
