High Mast Light  Instructions for Use

In the rectangular inner cavity at the bottom of the lift-type high pole lamp, in addition to the electrical control system, a motor and other lifting systems are also installed. The electrical control system is installed inside the light pole to avoid failures in the lifting movement caused by harsh outdoor environments. Various circuit overload protection devices are installed in the electrical control system.

The conductors of the circuits in the system are widely plated with copper-based silver to ensure good electrical connections. The lifting system of the lifting high pole lamp drives the lifting and lowering of the lamp panel through components such as a motor, (electromagnetic braking) worm gear reducer, safety coupling, main wire rope, auxiliary wire rope, rope divider and movable pulley group. The worm gear reducer has strong self-locking ability, compact transmission, and large transmission ratio. In order to reduce the worm gear and worm gear ratio and reduce the rising torque, a set of moving pulleys are specially added to make the lifting speed of the lamp panel less than 0.2 meters/second. .

The main steel wire rope is connected to the auxiliary steel wire rope of the lamp panel through a rope splitter, which can avoid the entanglement of the auxiliary steel wire due to the stretching of the main steel wire. The main and auxiliary steel wire ropes are made of high-strength, corrosion-resistant 6*19 type non-rotating galvanized steel wire ropes. The lifting pulleys all use hot-dip galvanized A3 steel brackets, stainless steel shafts, and copper pulleys to ensure that they will not rust under normal atmospheric conditions and operate flexibly.

Various fastener washers, clamp rings and other parts are also made of hot-dip galvanized parts or stainless steel. The lamp panel is equipped with 6 sets of guide pulleys and more than three sets of braking devices. When the lamp panel is raised or lowered, the guide wheels distributed at 120 degrees roll along the surface of the lamp pole to ensure that the lamp panel does not swing. The surface of the working part where the guide wheel of the lamp panel is in contact with the surface of the lamp pole adopts rubber hot pressing process. In order to fully ensure that the lamp panel automatically stops when it reaches the extreme position, the lamp panel is equipped with reliable limit switches for its rising and falling movements, and is equipped with over-travel protection.

The lifting and lowering of the high pole lamp panel is achieved by changing the rotation direction of the motor. For security and anti-theft purposes, the rectangular cavity is equipped with a sealed door, and a special door lock is installed on the sealed door.
