POWER COLLECTION Sample Clauses
POWER COLLECTION. 2.1. Electrical power from overhead wires is leaded to trolleybus with power collectors. The power collector is comprised of a pole, a trolley electric current collector and a replaceable collector insertion. Power collectors are hinged to trolleybuses, and turning in horizontal and vertical directions.
2.2. Poles shall be made of insulated material or metal covered with insulating material resistant to mechanical shocks. Annex 7
2.3. Power collectors shall be designed to maintain adequate positive contact with the overhead trolley electric supply wires when the wires are located at 4 to 6 metres above the ground and trolleybus axis to axis deviation distance of at least
POWER COLLECTION. 2.1. Electrical power shall be obtained from the contact wires by means of one or more power collection devices, normally comprising two trolley booms. (A single trolley boom or a pantograph may be used in guided applications). A trolley boom shall consist of a roof mounting (trolley base), a pole, an electrical power collector (trolley head) and a replaceable contact surface insert. Trolley booms shall be mounted so that they can turn in both horizontal and vertical directions.
2.2. Poles shall be made of an insulated material or of metal covered with insulating material and shall be resistant to mechanical shocks.
2.3. Power collectors shall be designed to maintain adequate positive contact with the contact wires when the wires are located at between 4 and 6 metres above the ground and, in the case of trolley booms, to allow the longitudinal axis of the trolleybus to deviate at least 4.0 metres to either side of the mean axis of the contact wires.
2.4. If the power collector becomes accidentally detached from the contact wire (de- wired), the upper end of the power collector(s) shall not be raised higher than 7.2 metres above the road, or 1 metre maximum above the contact wires at the time of de-wiring, nor lower than 0.5 metres above the roof of the trolleybus.
2.5. Each trolley boom shall be equipped with a device which retracts the boom automatically if the pole unwires.
2.6. The trolley head, if dismounted from its normal position on the pole, shall be remain attached to the pole and must not fall down.
2.7. The insulation resistance between the electric power collector and the roof mounting/trolley base shall be at least 10 МΩ:
2.8. Power collectors may be equipped with remote control from the driver's compartment, at least for retraction.
2.9. Provision shall be made to enable the driver to replace, if necessary, contact surface inserts while the vehicle is in operation on the road.
