How are buildings, installations and materials divided?
Provisions on the division of equipment and materials for engineering construction? [answer] the division of equipment and materials in engineering construction is directly related to the reasonable division of investment structure, budget preparation and calculation of construction output value. In order to reasonably determine the project cost, strengthen the investment in the process of construction and management, the equipment and materials in the engineering construction is unclear, especially the universal controversial common problems and put forward the principle of division of fifteen copies of "national unified installation project budget quota" of the equipment and materials are divided, the provinces, autonomous regions and municipalities directly under the central government and the relevant departments of the State Council, the Department should be combined with the local situation, formulate rules for its implementation, and report to the Ministry of construction for the record.

What are the principles, performances and uses of the commonly used construction machinery equipment?
2.: Principle: loader loader work, powered by a flywheel of the diesel engine to the hydraulic torque converter, the torque converter will drive to the gearbox, and before and after the output flange of the gearbox, the power output of the gearbox after the transmission shaft are respectively transmitted to the front and back drive axle to drive the wheels forward. Performance: 1) Central articulated frame, turning radius is small, flexible and convenient operation in narrow space; 2) using hydraulic mechanical transmission, according to the size of the external resistance and automatic stepless speed change, which can make full use of engine power, and improve the maneuverability, simplifies the loader operation. Is to protect the transmission parts and engine; 3) adopts full hydraulic steering, power shift transmission, hydraulic or flexible manipulation, portable and flexible machine; 4) stable and reliable operation; wide use of low-pressure off-road tires, rear axle swing, with good cross-country performance and through the performance by 5); gas cap oil disc brake system and brake foot up, emergency braking system, the braking performance is safe and reliable; 6) with advanced structure and bright cab. The air conditioning system operates more comfortably. Uses: loaders are mainly used for shovel, loading, unloading, transport of soil and stone a kind of bulk materials, rock and hard soil can also be slightly shovel operations.
