The use of gas buses in China mainly focuses on the neighboring provinces and cities of the three major gas-producing regions in the central and western regions where gas resources were developed earlier and where reserves are abundant, as well as developed economic regions where gas transportation is well-developed.

As of the end of 2004, the country has identified 16 cities (regions) in Beijing, Shanghai, Chongqing, Tianjin, Sichuan, Hainan, Harbin, Changchun, Xi’an, Urumqi, Guangzhou, Yinchuan, Jinan, Qingdao, Langfang and Xiangyang as the focus of clean vehicles. The promotion of cities (regions) can be broadly divided into: Sichuan-Chongqing region, northeastern region, Yangtze River Delta region, Beijing-Tianjin region, Central Plains region, Guangzhou-Shenzhen region, and Hainan region.

As of the end of 2004, there were approximately 40,000 gas buses in China. The use of gas buses in 16 urban areas is described below.

Beijing: The alternative fuel buses for promotion and application mainly include: compressed natural gas (CNG) buses, liquefied petroleum gas buses (LPG), and liquefied natural gas buses (LNG). Among them, CNG passenger cars and LPG passenger cars have already begun to use and are in the stage of industrialization; LNG passenger cars are still in the demonstration operation stage.

By the end of 2004, Beijing had 2,089 CNG buses (mostly Cummins CNG engines, all produced by vehicle manufacturers, of which 800 diesel-fueled CNG vehicles), and 1712 LPG buses (including diesel LPG vehicles There are 69 LPG refueling stations, 27 CNG refueling stations and 1 LNG refueling station. Beijing has become the city with the largest number of CNG buses in the world. The buses used are mostly produced by Beijing Jinghua Bus Factory.

Beijing plans to use CNG and LPG fuels for 90% of buses operating in urban areas by 2008.

Heavy Duty Shelves

What is heavy-duty shelving ?

Heavy-duty shelves are the most commonly used shelves, each layer bearing more than 500kg, and the name is derived from this. It has good picking efficiency and can store heavier items, but the storage density is low. Heavy-duty racks are also called Pallet Racks. They have the characteristics of heavy bearing capacity, wide range of height adaptation, mechanical access, and high selection efficiency, but the space utilization rate is general. Widely used in manufacturing, third-party logistics and distribution centers and other fields, it is suitable for both multi-variety and small-batch items, as well as small-variety and large-volume items. Such shelves are most used in high-level warehouses and ultra-high-level warehouses (most of the shelves in automated three-dimensional warehouses use such shelves).Heavy-duty metal shelves

Why Heavy-duty shelves ?

1. Usually, the goods are stored on the shelves after being assembled by pallets, storage cages and other unit container equipment. The load of each unit is generally within 4000kg, and two units are usually placed on each floor.

2. It is one of the most common and widely used shelves, suitable for most warehouses or product goods.

3. It has 100% random selection of goods. Handling machinery such as forklifts can reach any cargo space for storage operations, and storage operations are convenient and fast!

4. Use mechanical handling equipment for storage operations.

5. The span of the unit shelf is generally within 4m, the depth is within 1.5m, the height of the low and high warehouse shelves is generally within 12m, and the height of the ultra-high warehouse shelf is generally within 30m (such warehouses are basically automated warehouses, and the total height of the shelves is determined by It is composed of upright columns within 12m of several sections).

6. The height of each layer can be adjusted freely by an integer multiple of 75mm.
