This single arm traffic control barrier is the answer to private and public traffic control, in airports, hospitals, etc.
The 1″ x 6″ (2.54cm x 15.24cm) barrier arm is made of light wood such as white pine, up to 12 feet (3.66m) in length and finished with an exterior drink paint. Lined on both sides with diagonal yellow stripes for better visibility. The arm is fitted with a quick-fixing flange that allows easy positioning in the event of breakage without having to dismantle the entire control system.
Doorlec’s TCBOS model features a double synchronized drive device. It is designed to withstand the severe regime of continuous operation.
Heating element of 500W controlled by thermostat ensuring a normal temperature in the control cabinet in the most extreme atmospheric conditions, preventing freezing of gear reducer oil and eliminating humidity on electrical components.
Accepts any optional equipment for full automation of operation. (See Catalog No. F113).
Control by three push-buttons:
Momentary push type to open, close and stop. The control can be stopped in any position and the barrier can be opened or closed from this position. On request, the close button can be wired to respond only to a continuous press. Control circuit: 24V AC for user safety.
Barrier cabinet:
Constructed of welded 10 gauge cold rolled steel; grind smooth welds. Two lockable access doors located on the opposite side of traffic for easy maintenance and service. The top cover is also removable for easy adjustment of limit switches and drive mechanism. Access doors are gasketed and designed to meet EEMAC Class 4 requirements. Totally waterproof assembly.
The gate cabinet is treated with a coat of rust inhibitive primer and finished with a spray coat of beige-gold enamel.
Changeover contact:
Heavy duty type.
Discount:
By means of V-belts and pulleys for the primary reduction and a worm gear reducer. 60:1 single stage ratio for secondary reduction to barrier drive shaft. Angular speed of the barrier: 32o/second. Opens or closes in less than 3 seconds.
Limit switches:
Rotary type with precision microswitches, to stop the barrier in the up or down position. Easily adjusts without tools.
Engine :
1/3 HP (249W), 120V or 240V single phase with manual overload and brownout protection.
The traffic control barrier is pre-wired, color coded and labeled at the factory.
Each order is delivered with its wiring plan and installation manual.
The control is tested at the factory before it is shipped.
Reduction:
TCBOS operator utilizes two 4L V-belts, one 1-1/2″ (3.75cm) type A double cast-iron pulley and two 8″ (20.32cm) die cast aluminium-alloy pulleys, balanced for smooth operation as primary reduction. Secondary reduction is achieved by a 60:1 ratio single-stage worm-gear reducer, running in an oil bath. Cast-iron alloy housing. Hardened and ground steel worm and alloy bronze worm-gear for greater wear life. High-speed taper-roller bearings, double-lip, spring-loaded seals to keep lubricant in and dirt out. One inch (2.54cm) diameter double-output shafts, hardened and ground for greater strength.
Double-Link Drive:
Connecting bars and crank-shaft are synchronized for smooth action. Rotating on self-lubricated “oilite” bushings and high-speed cast-iron flanged bearings. Connecting bars and drive-shaft are made of solid cold rolled steel and are finished in black oxide to prevent corrosion. Mechanical action is such that brake or mechanical stop are not required.
Cabinet:
Weatherproof seam-welded cabinet, constructed of 10 ga. C.R. steel with all seams ground smooth. Size: 14″ x 15″ x 46″ high (36cm x 38cm x 117cm). Two lockable access-doors are located on side opposite to traffic for easy maintenance and service. Top cover of housing is also removable to facilitate adjustment to limit-switches and drive mechanism. Access doors are gasketed and designed to meet EEMAC 4 classification. A totally weatherproof assembly. Two cylinder locks and four keys are provided. The cabinet is finished with two coats of red oxide primer and two coats of gold-tan scratch-retardant baked-enamel paint, to withstand environmental conditions.
Electrical Control Cabinet:
Factory pre-wired, made of 14 ga. C.R. steel. Pre-formed size: 8″ x 16″ (20.3cm x 40.6cm). Mounted on unit chassis with four zinc-plated steel-bolts. Can be removed easily when required.
Limit Switches:
Rotary-type cams, mounted on output drive shaft, on their preset travel, activate the micro switches to cut power of motor in both up or down directions. Operating force on limit-switches: 4oz. (113.4g) maximum. Contact separation: .020″ (.05cm). Terminations: 0.25″ (.625cm) quick connect.
Motor Control:
Heavy-duty reversing contactor, two sets of three-pole contactors on a common frame, mechanically interlocked to prevent simultaneous closure. Clapper-type armature with three-point suspension, auxiliary contacts SPDT or DPDT (as required) on each armature. Coils: 24V. A.C. Load contact amps: resistive: 15 amps @ 120V. A.C., 10 amps @ 240V. A.C., 5 amps @ 600V. A.C.; Inductive: 2 H.P. (1492W) max. Terminals: .25″ (.6cm) quick connect. Mechanical life: over 10 million cycles.
Transformer:
25VA step-down transformer is provided, 120V., 240V. A.C. primary to 24V. A.C. secondary, Class II. For control wiring distance over 50 ft., consult factory for proper VA of transformer or minimum control wire size.
Barrier Lifting Arm:
Made of clear wood such as white pine, 1″ x 6″ (2.54cm x 15.24cm) extending up to 12 ft. (3.66m) max. All wood portions of the arm are painted with two coats of exterior black paint. Diagonally-striped, black and yellow traffic warning tape is applied to both sides of the gate arm for better visibility. Arm has a quick-change clamp to facilitate replacement if broken, without having to dismantle the drive system.
Motor:
1/3 H.P. (249W) rated for continuous duty. Instant-reverse type capacitor starting 120V. or 240V. single-phase, 1725 RPM. Ball-bearings permanently lubricated. Frame : rigid type 56. Shaft: 5/8″ (1.56cm) diameter.
Traffic-control barrier is pre-wired, colour-coded and tagged.
Wiring diagrams, installation manual are enclosed with each unit.
