The main structure of the semi-trailer towing platform includes the tow bar, the tow ring, the safety hook, the tow frame, the tow base, the traveling mechanism, the electrical circuit system, the braking system, etc..
Semi-trailer is widely used as the main vehicle in road transportation system. When the semi-trailer's center of gravity is interfered by the crosswind, the large lateral windward area is prone to rollover, folding of the tractor and trailer, and driving out of the lane, which brings serious road safety problems.
The dump semi-trailer is suitable for the transportation of bulk goods such as coal, ore and construction materials. Dump semi trailers can be divided into two categories according to their purposes: one is heavy and super heavy dump trailers for off-road transportation, which mainly undertake transportation tasks such as large mines and projects, and are usually used together with excavators.
In order to save energy, protect the environment and reduce vehicle fuel consumption, European engineers also try their best. At the Hanover motor show, BPW showed an axle with an energy recovery system called Epower. The working principle of this system is very simple. The axle hub is equipped with a generator, which can realize braking and power generation when the vehicle goes downhill.
A semi-trailer is one in which the axle is placed at the center of gravity of the vehicle (when the vehicle is uniformly loaded) and equipped with a coupling device that can transfer horizontal or vertical force to the tractor. Common semi-trailer categories: dump semi-trailer, low flat semi-trailer, container semi-trailer, tank semi-trailer, van semi-trailer, etc.
The advantages of ordinary steel are strong plasticity and relatively cheap price. In recent years, with the increasing requirements of users for vehicle lightweight, the raw materials used by special vehicle enterprises are becoming more and more diversified, including not only common Q235 and Q345 steels, but also high-strength steels, aluminum alloy materials and composites.
When the special semi-trailer approaches the turning point, you need to send a left turn signal and reduce the speed within an appropriate distance in advance. Then you should shift into a low gear and drive close to the right side of the road, as well as turn on the left turn light at the same time. You should also observe the situation on the road. If the turning of the vehicles will not affect the vehicles on the road, you can quickly turn to the left and foot the steering wheel to make the vehicle slowly drive to the left of the road. When the front wheel approaches the roadside (about 1m away from the roadside), please quickly turn two to three directions to the right and stop.
As the blades become larger and longer, the transportation of wind turbine blades is a big problem and a technical problem that requires calculation and planning. What method is used to transport blades safely and economically?The longer the blade, the more difficult it is to transport and the highe
In the traditional concept, people are very familiar with the steel trailer. Through practical use and experience accumulation, they have a full understanding of the structure and bearing capacity (strength) of the steel trailer. But for the domestic new all aluminum alloy trailer, how about its bea
