Pole: Usually refers to the new lighting device 15 meters above the steel cylindrical poles and power combined lighthouse constructed. It consists of the lamp, interior lighting electrical, rod and base portion. Head shape according to user requirements, ambient, lighting needs to be specific; internal lighting and more from the floodlights cast light composition, light source with NG400 HPS lighting radius of up to 60 meters. Rod is generally cylindrical structure alone, with steel rolling a height of 25-40 meters means new lighting device 25 meters steel cylindrical poles and power combined lighthouse constructed. It consists of the lamp, interior lighting electrical, rod and base portion. Head shape according to user requirements, ambient, lighting needs to be specific; internal lighting and more from the floodlights cast light composition, light generally use high-pressure sodium and metal halide. Lighting radius of up to 60 meters. Rod is generally cylindrical structure alone, with steel rolling a height of 15-40 meters. Pole of Use: City Square, railway stations, docks, garages, roads, stadiums, flyovers. Generally it is divided into lift and non-lift. Lift the main bar height is 18 meters or more generally, easy to operate electric lift, Medallions raised working position, automatically to disk automatically off, hanging ditch, wire rope and unloading. Lift pole set up both manual and electric lift control mode, so that you can safely and securely Medallions to 2.5 meters from the ground, to facilitate maintenance. Manual remote control unit lead wire length of 10 meters, the remote operator Medallions lift in 5 meters, which can ensure the safety of operating personnel. Lift pole is also equipped with some spare cable, when Medallions position to minimize the cable end into a socket in the electrical control system, and the other end into the junction box Medallions on, and so will be able to supply power directly to Medallions , repair lamps. All lift pole lamp sealing to IP65 international standards to prevent dust, rain ingress, ensure lamp life. Light material generally good corrosion-resistant aluminum alloy plate and stainless steel. Rectangular cavity in the bottom of the lift pole, in addition to installing electrical control system is also installed outside the lift system such as a motor. Electrical control system is installed inside the pole, to avoid harsh outdoor environments lead to failure of the lifting movement. Electrical control system is equipped with a variety of circuit overload protection devices. System conductor circuits widely used copper-silver-plated to ensure good contact with the electrical connection. Pole lift hoist system is through the motor, (electromagnetic brake type) worm reducer, safety couplings, the main wire rope, wire rope deputy, sub-rope and pulley sets and other components of the drive Medallions lift. Self-locking worm gear units of capacity, compact drive, transmission ratio is large, in order to reduce the worm, the worm gear ratio, reducing the rise in torque, particularly the addition of a set of movable pulleys, make Medallions lifting speed of less than 0.2 m / sec. . Main rope through the sub-rope and wire rope connected Medallions deputy can avoid stretching main caused deputy steel wire wound. Main and auxiliary wire rope are made of high strength corrosion resistant non-rotating type 6 * 19 galvanized steel wire rope. Lifting pulley block are used after the A3 hot galvanized steel frame, stainless steel shaft, copper pulley, ensure that under normal atmospheric conditions do not rust flexible operation. Fasteners gaskets, collars and other parts are also used hot galvanized or stainless steel. There are 6 set of guide pulleys and brakes on more than three Medallions, was 120 degree distribution of the guide wheels rolling along the pole surface to ensure no swing Medallions Medallions lifting or lowering process. Working part of the pole surface of the guide wheel contact surface Medallions rubber hot bonding process. In order to fully ensure Medallions to the limit position when the automatic parking, Medallions rise, fall sports are housed reliable limit switch, and has over-travel protection. Medallions lifting pole is by changing the direction of rotation of the motor to achieve. For security alarm, rectangular cavity with sealed doors fitted with special locks on the door seal.
