Study Notes

Types and Operation

Two barrier types are available: one without a hand generator (110V AC or 24V/110V DC), and one with a hand generator (24V/110V DC).
Operating sequence begins with opening detection contacts and unlocking the boom. Then, the boom moves, and finally, the boom locks in position and closes the detection contacts.
Open position: 85-90 degrees from horizontal.
Closed position: 0-2 degrees from horizontal.
Operation time is less than 12 seconds at rated voltage, but can be up to 20 seconds at 75% rated voltage.

Technical Specifications

Boom Construction

Boom is made of galvanized iron sheet in an octagonal shape.
Available in 4 sections, each 2.44 meters long, with total lengths of 4.88m, 7.32m, or 9.76m.
Sections are painted with alternating 300mm black and yellow bands.
A red disc (600mm diameter) with a STOP sign is featured.
Includes an LED boom light with a built-in fuse in the center.

Motor Specifications

Class B insulation.
Short-time 10-minute rating.
Rotation in both directions.
Overload protection using special MCBs.
Varying operating current based on type:
- AC (110V): 2.5A normal, 4A maximum
- DC (24V): 4A normal, 7A maximum
- DC (110V): 1A normal, 1.8A maximum

Safety Features

Fail-safe locking in both vertical and horizontal positions.
Fracture segment for protection against impacts.
Snubbing device for gradual boom movement.
Emergency operation capability.
Protection against unauthorized access.
