What is the standard for a residential car?
The RV is what we usually call a RV. As its name implies, it is a car like a house. Its functional equipment is similar to that of a house. It is suitable for tourism or the car of people who need to work in the field. The equipment inside the car is basically the same as the house in the home, so it can be called an RV. The main devices in the car are sleeping tools, kitchen and bathroom facilities, lighting of tables and chairs, and necessary storage facilities. So what are the rigid standards that need to be strictly observed for such a car? First, quality requirements The styling design, production raw materials, etc. of a residential vehicle need to be designed, manufactured and selected according to the relevant regulations of the country. A well-built residential vehicle must undergo inspection and inspection by the inspection department before it can be put on the market for sale before it can be used by consumers. Second, the body device requirements Anti-corrosive materials must be added to the exterior of the car body to protect the car from damage in extreme conditions in the wild. In addition, if the RV is relatively high and the distance between the door and the ground is more than 40cm, a non-slip door ladder should also be provided to facilitate personnel to get on and off. There is also that the tires of residential vehicles should be stable and easy to dismantle and repair. Third, the internal device requirements The internal alarm system, fire-fighting system (fire extinguisher) and liquefied gas safety inspection system can not be less. The internal lighting can not affect the driver's sight and ensure safe operation. The appliances used in kitchen and bathroom facilities should comply with the relevant regulations. Fourth, the car device requirements The compartments should have good sealing and heat preservation, ensure smooth ventilation, drainage pipes are also essential, and the compartment structure must be solid and stable. Ensure traffic safety. The above are some of the specific standards for residential vehicles. I believe that everyone knows more about residential vehicles. They are suitable for travel and wilderness vehicles. Consumers can refer to these standards when purchasing and renting a residential vehicle in the future. I believe they will play a great role. effect.
The general name of Construction Machinery used in engineering construction. Widely used in construction, water conservancy, electricity, roads, mines, ports and national defense and other engineering fields.

Brief introduction
Construction machinery is an important part of equipment industry. In general, where the construction of earthwork engineering, road building and maintenance, flow up necessary for heavy loading and unloading operations and various construction projects required comprehensive mechanized construction engineering machinery and equipment, known as the mechanical engineering. It is mainly used for national defense construction projects, the construction of transportation, energy industry development and production, mining and other industrial raw materials of construction and production, agriculture, forestry and water conservancy construction, industrial and civil construction, urban construction, environmental protection and other fields.
In the world, to address the basic similarity, which the United States and the United Kingdom said for construction machinery and equipment, Germany for construction machinery and equipment, Russia called for building and road construction machinery, known in Japan as the construction machinery. In the Chinese part of the product is also known for construction machinery, and in mechanical systems based on the State Council set up the industry approval referred to as mechanical engineering, has continued to the present. Countries on the delineation of the industry product range roughly the same, China Construction machinery and other countries comparison also increased the railway engineering machinery, forklifts and industrial handling vehicles, decoration machinery, elevator, pneumatic tools, such as industry.
Brief history
Humans have a long history of using lifting tools instead of manual labor. The history about 1600 BC, Chinese used shaduf and windlass. The former is with heavy leverage, which is the prototype of hand winch. Ancient Egypt and Rome, lifting tool also has more applications. The development of modern engineering machinery, began after the invention of the steam engine, in the beginning of nineteenth Century, Europe appeared a steam engine driven excavator, road roller, crane, etc.. Since the invention of the internal combustion engine and the electric machine, the construction machinery has been developed rapidly. After the Second World War, the development of more rapid. Its variety, quantity and quality directly affect the development of a country's production and construction, so all countries pay great attention to it.And now, in a variety of engineering machinery can see the wireless control function.
General heavy industry construction machinery
1 mining machinery such as single bucket excavator (also can be divided into crawler excavator and wheel type excavator), multi bucket excavator (also for Bucket Wheel excavator and chain bucket excavator, bucket trenching machine (and bucket wheel trencher and chain separating bucket trencher), rolling mining and milling machine, cutting excavators, tunnel boring machine (including the shield machine) and so on.
II of earthmoving machines such as bulldozer (also can be divided into rubber tyred bulldozers and crawler bulldozer, scraper can be divided for crawler self-propelled scrapers, tire scraper and towed scraper), loader, can divide again for wheel type loader and crawler loaders, graders (can be divided into self-propelled grader and towed grader), transport vehicle (also can be divided for uniaxial transport vehicle and biaxial traction transport vehicle), flatbed truck and dump trucks.
The hoisting machinery such as tower crane, self-propelled crane, derrick crane, Grab crane etc..
The compaction machinery such as tire road roller, smooth wheel roller, single foot pressure roller, vibratory road roller, ramming machine, tamping machine.
The piling machinery such as drilling machine, diesel hammer, hammer vibrating machine, etc..
The reinforced concrete machinery such as concrete mixer, concrete mixing station, concrete mixing building, concrete conveying pump, concrete mixing and transporting car, jet concrete, concrete vibrator, steel processing machinery and so on.
The road machinery such as flat machine, ballast cleaning machine etc..
The rock drilling machinery such as drilling rig, pneumatic rock drill, electric drill, rock drill and DTH Drill etc..
To other engineering machinery such as erecting machine, pneumatic tools (pneumatic tools) etc..
Industry classification
A wide variety of mechanical equipment. Some parts of mechanical equipment can carry out different forms of mechanical movement when they are running. The mechanical device is composed of a driving device, a speed changing device, a transmission device, a working device, a braking device, a protection device, a lubricating system, a cooling system, and other parts.
