What should pay attention to driving at night? In the darkness, the driving school learns to use light to drive at night. The headlights are an essential aid. In use, not only should not be allowed to open the fog lamp and headlights together (if you do not even clear the switch fog lights, then still look at the user manual it), but also understand how to use and change the light. During driving at night, if the speed of the vehicle is less than 30 km/h, a low beam light should be used. Under normal conditions, the light can be 30 meters away. When passing through the intersection, the speed should be decelerated at a distance of 50 to 100 meters from the intersection, and the high beam light should be turned into a low beam light. At the same time, the turn signal should be turned on to indicate the direction of travel. Do not walk black ash Some drivers often say that at night driving "go ash not go black", "go ash not go white, see black stop", simply put in the moonless night, the road is generally gray black, outside the road a Black; places where there is water will be reflective, and pits will be darker. In addition, the terrain can be judged based on the change of the front light pillar. For example, if the light beam shortens, it may be a corner or an uphill road. The light beam may become long or may be a downhill road. There may be pits in the light beam. Xu-Tong's trailer factory judges traffic conditions based on lighting. At night, it often encounters intersections. It can be used to predict the vehicle's driving status based on the illumination of side-by-side vehicle lights. If the intersection has scattered light from the front vehicle's high beam, it can be judged that the vehicle is still far away from the intersection. If the big light has a beam of light or there is bright light on the corners of the intersection, do a good job to prepare the line.
According to the light of the remote car lights can also help us determine the road ahead. In good weather conditions, if the other party is a high beam headlight, and the distance is far and clear, it can be determined that the road ahead is flat. If the high beam light line suddenly disappears, it can be judged that there is an intersection or a bend in front; The high-beam light line swings to the left and right, and it can be judged that there is a curving road in front; if the high-beam light goes down, it can be judged that the slope is ahead.
In short, it is important to drive at night. The first is to slow down. The second is to concentrate. Of course, you can't get up tonight or try not to catch the night. The low-profile flatbed semi-trailer is equipped with a wide range of non-front boards and is mainly used for medium and long-distance freight transportation. The frame of the semi-trailer is a beam-type structure, and the vertical beam is a straight gooseneck type. The web height is from 400mm to 550mm. The stringers are welded with automatic submerged arc welding. The frame is shot blasted, and the beam penetrates the stringers and welds the whole. The Xutong Trailer Factory consists of a tandem type dry plate spring and a suspension bearing. The structure is reasonable, and it has strong rigidity and strength. It is used to support load shocks. Low-profile semi-trailers are commonly used to transport heavy-duty vehicles (eg tractors, buses, special-purpose vehicles, etc.), rail vehicles, mining machinery, forestry machines, agricultural machines (eg excavators, bulldozers, loaders, pavers, cranes, etc.) As with other heavy cargoes, the lower the center of gravity, the better the stability and safety, and the greater the ability to transport ultra-high cargoes and obstacles through the head.
Reno Mattress Gabion Mesh
Gabion & Reno mattress is
a galvanized double twisted hexagonal woven mesh compartmented basket
with a rectangular mattress shape. The compartments or cells of the reno
mattress are of equal size and dimension and are formed by internal
diaphragms. Gabion & Reno mattress have been used for channel
linings, river training, soil retention, slope stabilization and other
applications successfully throughout the world for over 100 years.
Double twisted gabion & reno mattresses offer
many advantages, such as flexibility, durability, strength,
permeability, ecology, reliability, longevity, low cost and an aesthetic
appearance. The thickness of gabion mats is usually between 0.15-0.5m.
It is similar to gabion box which could be divided by several cells and
adopts thicker diameter wires to form mesh edge.
Features of Gabion & Reno mattress
Flexibility
One of the most important advantages of
gabion & Reno mattresses is their flexibility both for the
individual unit and the overall. The construction of the units permits
it to tolerate differential settlement without failure. This property is
especially important when a structure is on unstable soil conditions or
in areas where scour from wave action or currents can undermine the toe
of the structure and cause structural settlement.
Durability
Gabions & Reno mattresses built from
high strength double twisted hexagonal mesh filled with natural hard
durable stone and connected together to create a monolithic mass
structure capable of undergoing structural movement without any loss of
structural integrity creating a highly durable structure.
Strength
Gabions & Reno mattresses possess the
strength and flexibility to withstand forces generated by water and
earth masses. The most important and relevant strength characteristics
pertaining to gabion and reno mattress design standards are the mesh
punch strength, the mesh tensile strength, the pull apart resistance
strength of the mesh, and the corrosion resistance of the mesh. The
strength values of the double twisted mesh are located within the
individual product specifications for each product and are represented
in ASTM A975-97.
