National Development and Reform Commission: Coal Production and Transportation Needs Steady Progress

On December 15, the National Development and Reform Commission issued the “Notice on Accomplishing the Cohesion of Coal Production and Transportation in 2012”, requiring both parties of coal supply and demand to complete the signing of the contract within 15 days after the notification is issued. The notification also showed that in 2012, the coal transportation capacity of trans-provincial and regional railways was 834 million tons, which was 98 million tons less than that of coal across the province in 2011, a year-on-year decrease of 10.5%. The other notice clearly stated that support for coal mines and end-consumer companies signed contracts directly to reduce intermediate links.
Qiu Xizhe, a research fellow of China Investment Advisor Coal Industry Group, pointed out that this is the second time that the National Development and Reform Commission has shortened the time for coal bridging and negotiation. In 2009 and 2010, the National Development and Reform Commission left the negotiating parties no more than 30 days. Last year, the National Development and Reform Commission reduced it to 25 days for the first time, and this year it was shortened to 15 days again. The reason why the shortening of the coal coal ranks and the negotiation time is mainly because the coal companies are in a strong position in the negotiations and the power generation companies are struggling to cope. The time required for the signing of contracts is rigidly set to facilitate the early completion of contracted coal negotiations, which is more favorable for power generation companies.
In 2012, the coal transportation capacity allocation across provinces and regions was 98 million tons less than in 2011. This is another clear indication that the NDRC is gradually reducing the total amount of contract coal and expanding the market coal quantity, reflecting that the government will gradually relax The regulation and control of the coal market has promoted the marketization of coal trading. The shortcomings of contract coal are slowly emerging, and its compliance rate is gradually decreasing. Therefore, gradually reducing the proportion of contracted coal and promoting the marketization of coal trading are in line with the development trend of the industry.
Zhang Yanlin, research director of China Investment Consulting Co., Ltd., pointed out that supporting coal mines and end-consumer companies to directly sign contracts and reduce intermediate links is an initiative taken by the government to reduce the cost of coal purchased by thermal power companies. Judging from the actual situation, the existence of a large number of intermediate links is an important promoter of pushing coal prices upward. The direct signing of contracts between coal mines and enterprises will eliminate the costs of intermediate links and will reduce the production costs of thermal power companies.
The "2011-2015 China Coal Industry Investment Analysis and Prospect Forecast Report" published by the China Investment Advisor shows that in 2012, the supply and demand of coal will remain tight, and imbalances in electricity supply and demand will also occur in some areas and at certain times. In order to meet the demand for coal produced by electricity production and ensure the healthy development of the national economy, the government must take various measures to promote the progress of coal production, transportation and demand convergence.

Double Girder Overhead Crane is such that its bridge moves on elevated tracks, also called overhead traveling crane or  Bridge Crane . A bridge has its bridge longitudinally move along the elevated tracks laid at both sides and its carriage laterally move along the tracks laid on the bridge to make a rectangular working scope. In this way, the room below the bridge can be made fully use of while being free of hindrance of equipment on the ground.

It is used together with the Electric Winch . It is a Double Girder Bridge Crane, whose small car is moving on the railway of the main girder. 

Crane Girder:

The crane girder is of welded girder construction. This result in lower dead weight with a high degree of vertical and horizontal rigidity and small wheel loads being transmitted to the crane runway!

Lifting mechanism -- electric winch :

Electric winch is composed of reducer, brake, motors, drum and trolley frame , which can be mounted on bridge crane , Gantry Crane is to improve labor efficiency, improve working conditions for machinery .
