Lighting car (Light tower) is generally played in field operations at night and emergency rescue a significant role, for the case of sudden accident sometimes repair and exception handling and the like, the main role is to provide a field illumination light source in the case where there is no other mobile lighting . Lighting cars can be divided into two types of ball-type lighting cars and conventional cars, the more common brands are Beili and powerbaby.
The light source of the lighting vehicle is generally a metal halide lamp, and its advantage is that light is mainly emitted through the discharge of air in the light emitting tube, so there will be no broken wire, and the overall service life will be longer. And comparing this metal halide lamp with the same power iodine tungsten lamp will find that its brightness reaches six times that of iodine-tungsten lamp, and its service life is five times that of iodine-tungsten lamp. The overall power consumption is only iodine One-fifth of a tungsten lamp is enough to illustrate the benefits of using a metal halide lamp as a material.
The body assembly and body poles plus the lamps form a lighting car, which is generally equipped with two or four wheels and anti-roll brackets. The body pole mainly uses the winch and hydraulic device to raise or lower the overall height of the pole, and the pole is used to place the lamps so that each pole on the pole can freely rotate horizontally from What makes it possible to illuminate in every direction.
Most of the commonly used lighting vehicles on the market today are cast light fixtures, and such lighting is far away. Most of these lighting fixtures are in areas where ordinary roads, enclosed highways, and airport terminals need to be relatively closed but are in need of intense light and long-distance lighting.
The ball-type lighting vehicle adopts a lighting ball type lamp that adopts better light transmission and relatively high waterproof performance, and its material is selected from imported aerospace synthetic fiber materials. It is characterized by good anti-glare, both strong light and no shadow, but also a wide range of lighting in all directions. Therefore, this kind of lighting registration is very suitable for occasions where people, such as national highways and open highways, need to ensure safety.
Channel steel connectors are a commonly used connecting component used to connect channel steel and other components. Common classifications can be introduced from the aspects of material, use, and application.
1. Material classification:
-Steel connectors: Made of steel, with high strength and durability.-Stainless steel connectors: Made of stainless steel, with corrosion resistance and aesthetics.
-Aluminum alloy connectors: Made of aluminum alloy, they are lightweight, corrosion-resistant, and thermally conductive.
2. Usage classification:
-Bolted connections: By combining bolts and nuts, the channel steel and other components are connected together.-Welding connectors: Connect channel steel and other components together by welding.
-Bolted welded connectors: Combining the characteristics of bolted and welded connections, they have both the detachable nature of bolts and the firmness of welding.
3. Application classification:
-Structural connectors: used to connect channel steel and other components, and used in Structural engineering of buildings, bridges, machinery and other fields.-Support connector: used to connect channel steel and support components, to support the stability and safety of the structure.
-Fixed connectors: used to fix channel steel and other components, for fixing equipment, pipelines, etc.
Overall, the classification of channel steel connectors can be based on material, usage, and application. Different classifications have different characteristics and applicability, and suitable connectors can be selected according to specific needs.
