Q:What are the world famous mechanical equipment exhibition?

1, the German BMW Exhibition (BAUMA) sponsored by: Messe M nchen GmbH, held every three years, has held 30 sessions, the thirty-first will be in April 2016 11-17 in the German city of Munich exhibition centre. The German international engineering machinery, building materials machinery, mining machinery, construction vehicles and Equipment Expo is the world's largest and most influential international engineering machinery, building materials machinery, mining machinery industry exhibition, every three years regularly held in Munich in germany. The fair combines science and technology, trade, information and technical cooperation

Q:What is a door rack for a construction site? How high is it generally?

Door scaffolding has not yet unified design and product standards, the products of different specifications, quality is inconsistent. Not only for construction units to use and management of great difficulties, is not conducive to the promotion of applications, but also to the construction safety risks. Therefore, it is necessary to organize and issue a unified standard for door scaffolding

Q: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.

Q:What measures can effectively reduce the construction accident rate?

Hefei construction workers training _ eliminate dangerous source: eliminate the risk source of the system can fundamentally prevent accidents. But an important point of system safety is that it is impossible to completely eliminate all sources of danger and that people can only selectively eliminate several specific sources of danger. Generally speaking, when the risk of a dangerous source is higher, we should first consider whether we can take measures to eliminate it. A dangerous source can be completely eliminated by selecting the proper production process, technology, equipment, reasonable design, structural form or suitable raw material. For example: instead of the power system with pneumatic or hydraulic system, to prevent the occurrence of electrical accidents; instead of compressed air system for hydraulic system, to avoid the pressure vessel, pipeline rupture caused by shock wave; with incombustible materials instead of combustible materials, to prevent the occurrence of fire. It should be noted that sometimes measures are taken to eliminate certain sources of danger, but new sources of danger may be brought about. For example, an electric pneumatic system instead of a power system can prevent electrical accidents, but a physical explosion accident may occur in the compressed air system.

Q:What type of industry does the machinery and building accessories processing belong to?

Every industry has average tax rate, the contribution of each this argument does not exist, the industrial enterprise is nade VAT. The more value-added products you pay more.

Q:Construction machinery production need to deal with what documents?

Two, enterprise legal person business license (copy), with enterprise legal person business license duplicate copy, search three, all levels of safety production responsibility system and safety production rules and regulations directory and documents, operation procedures directory

Q:What are the main functions of construction equipment monitoring system?

To date, the console has always been built into blocks, in terms of control functions and number of cameras. Can be assembled according to requirements. In addition, the character generator is also arranged in the total time and address on the console, the date and time, minutes and seconds are displayed by this device, and be put in place to monitor the address and name display. It can be recorded on the video recorder, so that it will be convenient for future reference.

Q:What are the safety protection equipment, machinery and equipment, construction machinery and accessories for construction enterprises?

As well as scaffolding, protective fence, all belong to the safety protection facilities, does not belong to the safety protection appliances. Safety protection tools are many, it is characteristic of the operator to carry, I will not list

Q:What are the mechanical drawing software?

The 3D map only contact with SolidWords and Pro/E, Pro/E is better than Solidwords in general, but Solidwords is very simple to use, see Help tutorials you can learn to draw a three-dimensional map is not particularly complex easily to estimate a few days is enough. But any one of the two kinds of software, want to do not understand the words, expert advice is not really easy. UG and MasterCAM haven't touched much, but I've heard that it's suitable for processing stereogram.
