1, Weak management influences the normal working;

In the construction process, projects often have a large coverage; mechanical equipment and personnel face frequent arrangement. Managers blindly reduce machinery equipment, management organization and management personnel, or merge its functions into other departments, resulting in the disconnection between management department and operation department therefore influencing the normal working. 

2, Poor implementation of machinery maintenance regime resulting in intact rate of equipment reducing; 

Construction enterprises often overuse and give insufficient maintenance to equipment so that problems cannot be handled timely; In addition, maintenance staff is not responsible to cope with the job resulting in continuous expansion of equipment failure, which not only affects the quality and progress of the construction, increase maintenance costs and operating costs, and reduce machinery service life and security. 

3, Non-standard using accelerates machinery and equipment wear and tear; 

As part of the operator are weak in construction technology and equipment knowledge, do not pay attention to the specific conditions of the construction and operating methods, and blindly accelerate construction, so that machinery and equipment has been in overload working, or even illegal operations, thus speeding up the machinery and equipment wear and tear. 

4, Ignore the machinery and equipment upgrading results in inefficient construction and declining competitiveness. 

At present, parts of the construction enterprises don’t pay enough attention on failures and aging phenomena, so the upgrading of machinery and equipment is slow. Part of the management staff focus only on short-term economic benefits without considering the overall performance of the machinery and equipment, and even violate the relevant provisions to continue to use old machinery and scrap machinery, which result in greatly increased mechanical failure rate. It not only make a security threat to construction workers, but also result in reducing the overall construction efficiency, increasing construction costs, reducing competitiveness, and ultimately affecting the development of the entire enterprise.
