MIB20 AUTOMATIC BARRIER GATE

MIB20 Automatic
Barrier Gate
Technical Aspect
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 arm bouncing in the end positions. The lever
system locks the barrier arm at both end positions. In the event of
a power failure, it can still be moved easily by hand.
The completely driven system is attached to the
barrier housing as a single unit, and can be easily removed from the
housing, removing the mounting screws.
It is also a simple matter to change the handing
on-site from right-axial to left-axial.
Drive Unit

The barrier is driven by a torque motor mounted on
a central cast aluminum support. This support also contains the
bearings for the drive shaft, the gear box and the mounting for the
counterbalance springs.
The torque motor is designed for alternating
current. It does not require limit switch or friction clutch, hence
it is maintenance-free and can be stored in any position without the
risk of damage. In the end positions, the motor remains under power
assisting the mechanical locking of the barrier arm via the lever
system. This reduces the power consumption to the minimum. This
power is dissipated in the form of heat, which prevents the
occurrence of condensation and corrosion. This guarantees reliable
and problem-free operation.
The built-in position sensor provides precise
barrier arm status information to the associated controller. The
self learning control unit guarantees optimum braking without the
barrier arm bouncing or swinging out of the end position. The
barrier is factory wired, tested, ready to connect and supplied with
all necessary mounting accessories.
Housing

The housing is manufactured from 2mm zinc plated
sheet steel onto a base frame of stainless steel, then phosphate and
powder coat finished for maximum protection against corrosion.
Control units are mounted onto a removable zinc
plated sheet steel panel. All of the components within the barrier
housing are readily accessible through the maintenance door and
removable top cover. The housing is supplied in an RAL 2000 orange
colour finish as standard.
Control Unit

The MLC controller was specially developed using
microprocessor technology to ensure a flexible, modern approach to
the control techniques. It possesses all appropriate expansion
options including an I/O box and serial communication interface. The
MLC and ancillary control units are fitted onto the fold-out
mounting plate.
Barrier Arm

The barrier arm is extruded from highly stable
aluminum alloy to produce an octagonal profile of 100mm X 55mm X
1.6mm and finished with RAL 9010 white powder coat, then applied
with bright red reflective tapes strips, hence, the barrier arm is
readily visible even at night.
