BLG 77

The BLG 77 barrier fence is a unique barrier design that effectively prevents both vehicles and pedestrians from
unauthorised access. The BLG 77 is typically used for medium to low traffic volume and single lane access point
management. It is most often used for asset protection in facilities that utilise full perimeter barrier protection. The BLG
77 is capable of using barrier arms up to 6.35m and can fully open in 7 to 10 seconds.

SAFETY DESCRIPTION

Completed Cycle Locking: barrier arm mechanically locked in 1. Cabinet housing made of a strong welded steel frame up to
the fully completed 90º vertical up position and in the completed 2mm
horizontal down position
2. Upper cover is 2mm thick, folded and welded sheets steel,
HD Clutch: Torque limiter (Heavy-duty), which protects the security locked
electro-mechanical drive system
3. Key-lock safety access doors
Emergency Crank with safety circuit 4. Rigid fence made of an aluminium welded frame and modular

Power Failure: system will shut off and the gate should stay in panels. The panels are made of aluminium frames that hold
its current position dependent on the adjustment of the clutch the aluminium chain link mesh
and the position of the gate at the time of power failure. It may 5. Barrier fence is attached to a rotating shaft mounted on twin
continue to move slowly for a few seconds ball bearings
6. Barrier arm balancing achieved by means of integrated
ANTI-CORROSION PROTECTION adjustable compression springs
AND PAINT WORK 7. Electro-mechanical unit includes:
773 phases instant-reversing 500W motor
INTERNAL MECHANICAL PARTS 77Speed reduction gearbox, with worm screw type

Protected by electro-plated zinc mechanism
77Crankshaft/rod device with steel abutments
CABINET HOUSING 77Analog sensor combined with speed controller allowing

Housing finish is made of two layers. First one is a coat of a a smooth movement of the barrier and progressive
rich zinc epoxy primer. The second one is a coat of polyester acceleration and deceleration
powder structured coat with orange RAL 2000 as the standard 77Safety torque limiter with adjustable friction disks
colour. This protection ensures resistance to the most severe 77Transmission between motor and gearbox, by V-belt and
environmental conditions pulleys
8. Integrated heater for low temperatures
9. Emergency crank with safety circuit breaker for manual
operation of the barrier in the event of a power failure
10. Tip support: Electro-magnetically locking tip support
11. AS1320 control board enabling various commands and/or
accessory options:
77Possibility of 2 built in vehicle detectors (single or double
allowing 4 detectors)
77Overload protection
77Terminal blocks for motor, detectors relays and options
77Output dry contact for information on the barrier or to
command other equipments
77Status of the barrier’s position (open or closed)
77Status of the presence detectors
77Command for master-slave barriers (movement of one barrier
controlled by the other barrier)
