Lifting machinery industry in 2015 is expected to pick up a full recovery
Lifting machinery industry in China has experienced nearly a decade "blowout" type of development, the whole industry has entered a production contract, revenue fell cycles. China
bridge gantry crane CEO, industry analyst Yangshu Yan said: "In fact, starting in 2010, the industry has begun crane shot down, and gradually into a low-profit era, to the winter of 2012, the industry has come."
2013 lifting machinery industry growth slowed further, many crane companies in the homogenization of serious competitive environment difficult. Lifting industry in China has a "barometer" of the Chinese crane hometown in Henan Province Changyuan, past busy, machines roaring situation no longer exists, lack of factory orders, production team layoffs have become a common phenomenon industry . Funding strand breaks is very difficult for many companies in the brink of life and death. 2013 a quarter of the entire industry output profits fell nearly 60%.
Yang Shuyan analysis that led to the first quarter of 2013, corporate sales and revenue both fell mainly due to weak industry demand, but in the back of weak demand, not just domestic fixed asset investment growth and a decline in the real estate market five new national policy impact, but also the entire country in 2012 a continuation of the equipment manufacturing industry downturn.
hoist gantry crane industry over the last golden years, gave birth to the rise of a number of leading enterprises, but the excessive pursuit of speed and scale also resulted in overcapacity, irrational structure, product homogeneity, etc. invisible injury, this situation is growing stagnant 2012 annual performance is very obvious to the industry caused a lot of pressure. Enter 2013 in the enterprise revenue decline, the market demand slowdown Yan Chun situation, Changyuan also from the government level, the use of the visible hand pushing business strategic restructuring, guide enterprises to adjust product structure, promote the healthy development of the whole industry a reasonable .
In fact, some industry experts are not optimistic about the crane industry placanticline internal reorganization, because different companies kneaded together, sheer scale merger may not be able to achieve optimal results. Large enterprises and groups requires companies endogenous development and growth, rather than a simple merger and reorganization. For the entire industry, lifting, walking industrial upgrading, product upgrading, technological innovation, marketing model innovation is stronger placanticline crane industry and the country's key.
In the context of global economic restructuring, lifting machinery industry development trend of slowdown is inevitable. China's manufacturing purchasing managers index (PMI) 2013 year April index was 50.6, down 0.30%, which we analysts believe the industry is still in the stage of stabilization row irresolute. At what time it comes to bridge crane can really pick up when Yangshu Yan analysis, the future lies in integration and opportunities for more innovative marketing model. At present, the Chinese crane industry is still relatively extensive mode of development, technological innovation capability is weak, low value-added products, the overall big but not strong, the real recovery in the industry should be in the end of 2015.
How quickly achieve industrial transformation and upgrading, smoothly through the downturn adjustment period? How in the future market competition in the next round to seize the high ground, the entire hoist crane in the future development process need to solve the primary problem. "

Therefore, it is necessary in order to reflect properly installed crane overall eligibility to test the integrity of the whole crane and integrity.
(2) cranes are in use venues or buildings orbit. Therefore, its orbit or install base, and the crane itself, is able to complement each other well, and the ability to run whether they can adapt to meet strict requirements, must go through the proper installation and post-installation commissioning and testing concluded .
(3) Cranes high security requirements, safety devices must be complete and properly installed, in order to achieve a reliable, flexible, and accurate technical requirements.
(4) based on the importance of safe working bridge gantry crane the crane was put into use in order to meet the operational requirements of various loads, it must be conducted according to the provisions of the crane load, full load, overload static and dynamic load tests. These tests must be the operating state of the crane mechanism or specific for a stationary state. This requires the crane load test after installation only after the transfer of use.
(5) the crane wire rope and other flexible member, and many other parts will occur in some of the initial elongation under load, deformation, loosening. It also requires the crane crane installation, commissioning loaded after correction for repair, adjustment, handling and fastening. Therefore, we must do a good job crane installation, commissioning, speed and a series of work in order to ensure the future safety of the hoist gantry crane normally used.

Crane rental market in the future how to develop
Chinese province due to many, the rental market is uneven regional development, how to achieve healthy and sustainable development of the rental market, in addition to relying on market forces to adjust, but I think the parties should be explored in the following aspects:
First, the overhead gantry crane manufacturer to abandon the current sales model of vicious competition in the industry, under the guidance of orderly competition, manufacturers have this problem may have more feelings. Crane manufacturer recommends gradually focus from manufacturing into remanufacturing up, take a resource-saving road.
Second, the state sector response crane life to develop industry standards, the establishment of the crane exclusion criteria. And eliminated based on the annual number to each manufacturer to provide production basis.
Third, the national administrations of the annual certification of the crane in the national uniform standards for leasing companies in asset size, management and implementation of enterprise qualification management service capabilities, such as large and small Steel crane rental companies graded qualification management, crane certification the annual qualification linked with the enterprise, and promote leasing enterprise resource integration.
Fourth, leasing companies focus on intensive management of the road to go through the integration of assets, both to achieve professional management, will also make regional resource management, cost saving by taking the road to improve investment efficiency.
Five is the strength of the leasing companies established regional professional crane rental center, professional management of common hoist gantry crane equipment, such as counterweight, boom, hook first class, create a resource platform to share resources, reduce operating costs, and strive to achieve social maximized.

Tan Chinese crane rental market situation
Domestic crane rental business after several years of rapid development of the national economy, state-owned subsidiaries from five years ago, a crane rental company dominate the world, the evolution of what is now private and state-owned rival, mainly due to the more open
overhead bridge crane sales up to solve the private financing difficulties, coupled with private enterprises in the decision-making speed and operational flexibility, making the emergence of private enterprises in the crane industry, the Great Leap Forward-style growth. In this context, the domestic crane manufacturing enterprise scale, due to follow the market, there have been extraordinary development.
Beginning last year, but with the domestic economic growth rate to stabilize or even decline, finally appeared crane rental market oversupply, rental prices began to decline, and their utilization rate also decreased rapidly, coupled with the rising cost of the domestic variety, especially labor costs rise, the market has a large amount of small hoist crane , ROI began to rapidly decrease, some operators have begun to appear bad loss, making the driving force behind the development of leasing companies have lost the source, but also to continue the rapid development of manufacturing enterprises no basis, manufacturing companies also benefit from the development to the pursuit of scale to quality development.
Crane is a universal lifting machinery, due to structural wear low, state-owned enterprises will generally be set at a large crane depreciation 14 years, the other for 10 years. However, the current lease with the actual conditions of use, the general life of 20-30 years, this feature makes the crane rental market for more than after a substantial decline in return on assets leasing companies, manufacturers sales may decline substantially, the entire industry will present vicious competition. At present, the domestic leasing market is in this situation.
As previously described one conclusion: China's crane rental market since last year has ended a period of rapid growth, and leasing companies have entered into a vicious competition period, just over two years, the overall decline in rental prices 30-50 %, cranes payback period from 4-6 years, dropped to 6-10 years. Manufacturing companies also quickly dropped from the peak of development, although some factory sales value of these two years is relatively stable, but the gross margin decline. Part of the manufacturer's sales began to fall sharply. If allowed this trend continues,jib crane China crane rental market woeful.
