What is stage truck

The mobile stage car is a special type of car that is convenient for mobile performance and can be turned into a stage. The mobile stage truck is unfolded by mechanical device, built into a performance stage with a ceiling and a stage board, and equipped with special equipment such as stage lighting, sound, etc. Hanging lamps, sets, and structural devices that block wind and rain is used above the stage.  It is necessary to include two parts of the chassis part and the upper part, the top part is composed of the top plate side plate, and the side plate and the top plate are respectively controlled by four hydraulic cylinders to form the stage top of the stage, and the bottom plate is expanded into four hydraulic cylinders to be controlled into a stage. It saves time and labor. Also it is simple, safe and reliable with complete functions and beautiful appearance. Each stage truck must have 4 hydraulic legs. As one of mobile stage truck manufacturers in China, we have mobile stage truck for sale.

Stage trucks details

The whole vehicle is fully automatic operation, the operating platform is at the rear part of the car, it is concealed and locked when not in use. It is equipped with a full set of hydraulic operating system, which is quick and easy to operate. It is the most frequently used model for merchandising companies. Stage trucks can combined with a LED screen. LED mobile stage car, with the perfect combination of LED display technology, is divided into built-in LED display and external LED display, are the main scenes with LED display as the stage dynamic, enhance the performance lighting effect. There are 3 kinds of stage trucks. The single side of the carriage is fully automatic to form a stage countertop, the roof is half-turned, and an LED billboard can be installed. The other side of the compartment forms a stage backstage together with the carriage. The two sides of the truck expand together with the carriage to form the entire stage , and the roof rises. The three sides of the carriage expand together with the carriage to form the entire stage. Make full use of the side panels of the truck to expand the stage countertop.

he vulcanization reaction of RTV one  is initiated by moisture in the air. The commonly used cross-linking agent is methyl triacetoxysilane, whose Si-O-C bond is easily hydrolyzed. Acetoxy and hydrogen groups in water are combined to form acetic acid, and hydroxyl groups in water are moved to the original acetoxy position to become trihydroxymethyl silane. Ordinarily, organosilicon raw rubber containing terminal group of silanol, fillers, catalysts, cross-linking agents and other complexes are put into sealed hoses. When used, they are extruded from containers, vulcanized into elastomers using moisture in the air, and low molecular weight substances are released at the same time. When crosslinked with an alkoxy group, alcohols are released, which is called a dealcoholic RTV one. When crosslinked with the oxime group, oxime is formed, which is called dioxide room temperature vulcanized silicone rubber. Therefore, with the different cross-linking agents, RTV one can be used as deacidification, dioxide, dealcoholization, diamine, deamidation, and diketone, but deacidification is the most widely used one at present.

The curing time of RTV one depends on the curing system, temperature, humidity and the thickness of the silicone rubber layer. Increasing the temperature and humidity of the environment can accelerate the curing process. Under typical environmental conditions, the surface of silicone rubber can be non-sticky after 15-30 minutes, and the rubber layer with a thickness of 0.3 cm can be cured in one day. The curing depth and strength will gradually increase in about three weeks.

RTV one has excellent electrical properties and chemical inertia, as well as heat resistance, natural aging resistance, flame resistance, moisture resistance, air permeability, and other properties. They can keep elasticity for a long time in the range of - 60 - 200 C. It does not absorb heat and exothermic when curing and has small shrinkage rate after curing, and good adhesion to materials. Therefore, it is mainly used as adhesives and sealants. Other applications include in-situ forming gaskets, protective coatings, and seam materials.

The vulcanization reaction of RTV one proceeds from the surface to the depth gradually. The thicker the rubber layer, the slower the curing. When the deep part also needs to be cured rapidly, the gradual vulcanization method of layered irrigation can be adopted, and some rubber can be added at a time, etc. after vulcanization, the total vulcanization time can be reduced. Magnesium oxide can accelerate the vulcanization of a deep rubber.

1. Re-manufactured Sany 45 meters concrete pump, Isuzu chassis, 4RZ boom ground jack is leg lifting. First-level standard maintenance. High working stability.
2. 20 hours pressurized with water and debugging, exempted from inspection in perfect condition. New tires, new paint, overall maintenance for engine and hopper, just change nozzle, glasses plates, cutting ring, piston replacement. debugging and rectification to good condition.
3. Sany Quality+ Sin Hanyo Re- manufacture It's more reliable than buying a second line brand new Sany pump concrete.

The glass plate is an important part of the Sany pump truck. Although its volume is small, its technical content and processing cost are very high. At present, glass plate can serve for about 30,000 cubic meters of commercial concrete pumping. In order to improve the service efficiency of the arm gantry pump truck, it is very important to take corresponding measures to improve its service life.

Working characteristics of glasses plate

The eyeglass plate is a part of the S-shaped Sany truck mounted concrete pump distribution valve, connecting to the commodity concrete conveying cylinder. Driven by the swinging oil cylinder, the moving part S pipe swings from one commodity concrete cylinder to the other commodity concrete cylinder. The cutting ring vibrates with the S-tube attached to the eyeglass plate. The quick swing of the cutting ring causes intense wear between the eyeglass plate and the pre-mixed concrete. It also bears the impact of cutting off the stones. It can be seen that the eyeglass plate mainly works at room temperature and bears the impact force, shear force and very strong friction.

The main failure modes of eyeglass plate are wear and fracture failure. The wear between the eyeglass plate and cutting ring is abrasive wear. First, the cutting ring and the hole Angle of the eyeglass plate are blunt, and a smaller circular surface wedge-shaped trace is formed. The wear gap increases with the increase of abrasive particle size. When the gap is large to a certain value, the construction will be affected by severe leakage of the slurry. With the increase of pump height, the impact shear of the eyeglass plate will increase, the wear will be more intense, and it is prone to fracture and collapse.

It can be concluded from the above analysis that the surface of the eyeglass plate should not only have high hardness and wear resistance but also have the certain toughness and high fracture resistance.

The key parts are the original components of international first-class brands, and the most rigorous and rigorous production process and testing process are adopted to ensure the high quality of each zoomlion concrete pump china.

Matters needing attention in the selection of concrete pump truck

The volume of the construction business

The quantity of used boom pumps can be calculated according to the quantity of commodity concrete pouring, the actual quantity of conveyance of the single machine and the time of construction. For those commercial concrete pumping construction projects with a large amount of one-time concrete, it is advisable to have a certain amount of reserve in addition to being determined according to the calculation. In addition, the commercial concrete business concrete station with the annual output of 10~ 150 thousand m3 shall be equipped with 2~3 commodity concrete gantry pump trucks.

Product configuration

In the selection of product performance of concrete arm used pump trucks, the high starting point should be adhered to. If high-value concrete upper arm pump truck is selected, the standard of its products must be improved. The quality of the main components of the product, both internal quality and external quality, should be adapted to the high value of the whole vehicle.

Power system

Concrete frame pump truck adopts the full hydraulic technology. So it is necessary to consider whether the hydraulic technology used is advanced or not, and how the quality of hydraulic components. Because its power comes from the engine, so besides engine performance and quality, the performance of automobile chassis, bearing capacity and quality should also be considered.

The operating system

The operation control system of commodity concrete arm pump is provided with manual, wired and wireless control modes. Wired control is convenient and flexible, wireless remote control can be operated remotely. Once the circuit fails, the manual operation mode can be adopted.

After-sales service

As a special vehicle, the concrete arm pump truck should be required for its safety, mechanical performance, after-sale service, and parts supply. Otherwise, once the accident occurs, it not only affects the construction schedule but also will produce the unimaginable consequence.

Safety Matters Needing Attention in Machine Automated Manufacturing Line

1. Pay attention to the clamping force not too large (avoid damage)

Automated manufacturing line for machine processing mostly adopts the automatic design. When using it, we should pay attention to choosing appropriate clamping force according to the different types of materials, and not set too much tightening force. This may damage some of the processing materials, especially the surface of the bar.

2. Pay attention to the opening and closing range not too small (make the work more convenient)

Generally, the opening and closing range of automatic manufacturing line are moderate, but if the space environment permits, the opening and closing range can be increased as far as possible. Especially when taking large volume materials, we can adjust the opening range in advance to make it more accurate.

3. Be careful not to move too fast (avoid vibration)

In the use of a machine-automated manufacturing line, its operation stability should be the basic premise. If the size of the object is large, or because of other factors such as too fast running speed, the overall stability of the equipment will be reduced, which may cause a vibration of the machine-processed automated manufacturing line arm and reduce its grasping accuracy.

4. Note that sliding does not conform to shutdown (avoid affecting operation)

Machining automated manufacturing line work environment is more complex, and some materials are small in size, easy to enter the equipment to affect the operation of the equipment. Therefore, if there is slippage or obvious abnormal noise in the automatic manufacturing line of the feeding and unloading machine, the machine should be stopped immediately to check and prevent further damage to it.

Microcrystalline wax is amorphous solid wax, also known as purified ground wax. It is prepared from vacuum residue by solvent deasphalting, solvent dewaxing, deoiling, refining, shaping, and packaging. Its chemical composition is less than normal alkanes. The main components are cyclic hydrocarbons with normal or isomeric alkyl side chains, especially naphthenic hydrocarbons. The larger the molecular weight, the higher the content of isomers and long chain alkanes. Microcrystalline wax has the characteristics of small hardness, good flexibility, and stress, and tends to plastic flow, high elongation, good flexibility, and strong gel strength. 。 With its unique properties, microcrystalline wax is widely used in emulsion explosives, rubber, hot melt adhesives, crayons for cultural and educational supplies, rubber mud, wax paper, ink, lubricant, paint, polishing, spinning wax, casting mold, electrical and electronic insulation, medicine, cosmetics, food, and food packaging, etc.

The appearance of microcrystalline wax is ruined or white. The basic chemical composition of microcrystalline wax is fewer n-alkanes. The main components are cyclic hydrocarbons with n-alkyl or Iso-alkyl side chains, especially naphthenes. The higher the molecular weight, the higher the content of isoalkanes and long side chain naphthenes. The number of carbon atoms is 21, the molecular weight is about 1, the melting point is 1, and the chemical properties are stable. Compared with paraffin wax, microcrystalline wax has a higher melting point and molecular weight, higher refractive index, relative density and viscosity after melting, and lower shrinkage and surface tension under the same hardness. Therefore, microcrystalline wax has the characteristics of low hardness, good flexibility, plastic flow under stress, large elongation and good flexibility. In addition, microcrystalline wax also has a strong gel strength for oil products.
