Electric Lifting Barriers
'Italic text'' are used to control the Traffic, across the Railway lines. Airport, Security. These gates are modern and easy to operate. It is consume very low power. A generator can produce the power required for both barriers by simply rotating a crank. It is electrically operated device for closing the level Crossing against Traffic and comprises of an, manually operated hand generator, electric motor, circuit controller ,operating mechanism and boom.

Includes
The system meets the RDSO specification No. RDSO SPEC.NO. RDSO/SPN/180/2005 WITH AMD. APPROVED BY RDSO, LUCKNOW. 1. Level Crossing: That section of a road where the railway track crosses it at the same level. 2. Hand Generator: The generator unit along with very low maintenance gear drive unit capable of delivering power to operate Electric Lifting Barrier 3. Operating Mechanism: Consisting of clutch, reduction gear, boom shaft and suitable locking device 4. Boom: That part of the lifting barrier which in horizontal position prevents passage of road vehicles across the level crossing. The total length of the boom shall in maximum 4 section (depending on total length) joined by nuts and bolts for easy replacement. The length of the boom of the lifting barrier shall be approx 16/24/32 fts as per the requirement. The boom is painted with luminous stripes (reflective tape) alternately with 300-mm bands of black and yellow colour. The Lifting barrier shall have two booms, one across the road on either side of the level crossing, operated by independent mechanism

5. Snubbing Device: A device employed, apart from the clutch, to minimize the physical shock due to stopping the mechanism at the end of its stroke.

6.Direct Crank Handle: An appliance by which electrically operated lifting barrier may be operated manually by hand at the mechanism

7. Control Panel: A selector toggle switch is on the panel to operate either in Auto mode or Manual mode. In Auto mode red push button used for closing the barriers & green for opening. In Manual mode both the barriers are closed/ opened by rotating the crank handle. 8. Gear Mechanism Case: A weather proof case is provided to protect the driving motor, Gear box and circuit controller from rain and sun. Whenever the barrier is required to open/close manually direct crank handle can be inserted into the gear box. The mechanism is such that during opening/closing even though the barrier stops in between it stops at the same position without slippage to prevent accidents. 9. Circuit Controller: A seven segment circuit controller is used for sequential control of road signal, hooter and the barrier motor. The rotating movement of this controller is linked with the barrier itself, so that at totally horizontal (close) position or at totally vertical (open) position the power to the motor, which operates the barrier, should be cutoff. 10. Solenoid Lock: During closing operation as soon as the boom reaches horizontal position the boom tip rests on this lock post and locks with the spring loaded taper lock knobs automatically, which are projected from the lock body. When the green open button is pressed on the control panel these knobs are released by the solenoid provided at the back side of the lock and allow the boom open.

OPERATION OF LIFTING BARRIER
The operation of the Lifting Barrier shall take place in the following sequence: •	Open the detection contacts and simultaneously unlock the boom. •	Move the boom •	Lock the boom in the full horizontal or vertical position and simultaneously close the detection contacts.

ADVANTAGES
•	Gear mechanism is totally oil selected for smooth operation and operates at high speed ratio to ensure smooth operation of barrier. •	The Gear mechanism is such that, the boom connected to the Gear mechanism won't slip during the operation to ensure the safety of the trespassers. •	A manual lock release knob is provided to release the lock during manual operation. •	Lock knobs are of brass to minimize were & tear and rusting. •	Boom is made with 3mm aluminum sheet and joined with 5 mm thick plates, to make it rigid, to with stand the road traffic.

TECHNICAL SPECIFICATIONS
•	The Barrier operates with 24 V DC, at 3 amp rated current. •	24 V DC Low maintenance PMDC motor has been used. •	16 amp MCB used for motor protection. •	Only 10 sec time needed to close or open the barrier •	2.5 sq.m. cables are been used for total wiring for minimum voltage drop. •	All the electrical components are as per RDDSO approved vendors list. Application examples and function of the barrier lifting system.The Patel Electrically Operated Lifting Barrier can be used individually, in order to achieve a sluice arrangement forming a vehicle check point.

Advantages of the ELECTRICALLY OPERATED LIFTING BARRIER
•	Short operating time. Protection starts immediately. •	Boom in warning colour. •	Variable blocking height maximal approximately 1000mm. •	Clear width: up to 9m •	Stable construction, all basic parts consist of steel with high tensile strength. •	Low maintenance costs •	Easy service due to the separate drive cabinet. •	Tri Protect Long-Term Corrosion Protection •	Installation in all climate zones possible •	Emergency function by a hand pump or an accumulator (option) The boom raises very quickly to the upper position and blocks the road with variable heights up to max. 1000mm (center boom)
