What are the advantages of fine aggregate concrete pump?

Concrete pump is currently a lot of the construction side are commonly used as a mechanical device, it can greatly enhance the transport efficiency of concrete. The fine aggregate concrete pump as a special model, but also by the majority of the construction side. So Intel Wuhan fine concrete pumps have what advantage?
At present, many projects are often used to warm the fine aggregate concrete pump fine stone concrete or mortar filling layer filling layer large area, high efficiency of construction, and want to ensure the smooth progress of the project, the purchase of a high-quality fine aggregate concrete pumps can play a multiplier Effect. Specifically, we are now described below.

As a production and sales company specializing in the production of concrete pumps, fine concrete pumps currently has three characteristics: 1, fine aggregate concrete pump high power operation, small loss. 2, fine aggregate concrete pump flow components relatively long service life, saving production costs. 3, the entire mining system stable jobs, not because of pump operation doubt affect the operation of the entire mining system.

How scrap processing tower crane

Tower cranes, in the above construction machienry, crane plays a vital role. Since China Housing Industry rapid outbreak began, but also started a flourishing crane industry, as of 2007, half the world's total number of cranes are located in China, which also makes China become a country worthy of the crane. However, in the jungle so many crane operations, there are still a large number of crane belongs to the ultra-service phenomenon, which also brings great risks to construction safety.

    In fact, national and industry-related regulations have already pointed out many times, before and after installation and tower cranes in daily use should it be checked. Every weld metal structure can not be cracked, the metal structure can not be plastically deformed connecting bolt, pin quality to meet the requirements, the only retreat, locking measures, connecting bolt preload to regularly scheduled staff, wire rope lubrication and maintenance is good, broken wires may not be exceeded never allow off shares can not be plastically deformed joints Shengka standard, gearbox and fuel tanks must not leak, the hydraulic system pressure is normal, brake and limit the insurance sensitive and reliable transmission mechanism oiled, complete and reliable safety device, the electrical control circuit insulation is good. In particular, to supervise the tower crane drivers, maintenance electrician and mechanical maintenance man should always check inspection should focus on the vulnerability of the rope, hook, each transmission parts, limiting safety devices, found the problem dealt with immediately, so be people, fixed time, fixed measures to strictly prevent mechanical work sick.
    When crane time more than a decade, should inform the technical appraisal units identified by the use of units, if not to ensure the safety, then it should be done in scrap. In particular, some large crane, it is an order prohibiting the use of the State. There is a tower crane in the period of use, if the tower and front arm appear distorted. Living Steel closed and serious cases, should be scrapped ahead of schedule. Scrapped after dismantling the tower crane should as soon as possible to recover useful parts, made of metallic materials is an integral part of smashed recycled process, after some covet petty scrapped sent renovated tower crane rental market behavior, the same should be carefully investigation.

How to Calculate a Belt Conveyor

Conveyors can move a load both horizontally and vertically. To calculate the conveyor belt's power requirements, you have to consider both how far the load must move linearly and by how much a lifting motor will raise it. No universal formula links these variables to how much power the belt consumes. Manufacturers instead provide in the system documentation graphs or tables of data for you to consult for such calculations.

Instructions

1. Convert the horizontal transport distance to meters by multiplying it by 0.304. If, for instance, the belt must move material 260 feet horizontally: 260 x 0.304 = 79 meters.
2. Convert your hourly freight to metric tonnes by multiplying it by 0.907. If, for instance, the conveyor belt must move 330 tons each hour: 330 x 0.907 = 300 tonnes per hour.
3. Track the values from Steps 1 and 2 on the graph from the link in Resources. With this example, locate the 79 mark on the x-axis and note its intersection with the 300 tonnes per hour curve. The value on the y-axis, in this case 6, describes the horizontal conveyor motor's power requirements in kilowatts.
4. Convert the load's lifting height to meters by multiplying it by 0.304. If, for instance, the belt raises material by 40 feet: 40 x 0.304 = 12.16 meters.
5. Track the value from Step 4 on the second graph in the link in Resources. With this example, find 12 on the x-axis, and note its intersection with the 300 tonnes per hour curve. The y-axis value reveals an additional power requirement of 10 kilowatts.
6. Add together the power requirements from Steps 3 and 5: 6 + 10 = 16 kilowatts of total power.

Building Hoist construction

Building hoist is a work using a cage (cage) vertically along the guide rail rack (or inclination) used to transport personnel and materials movement machinery.

The structure is a building hoist cage carrying ladders and counterweight, wire rope hanging in the column at the top of the fixed pulley, columns and architectural structures rigidly connected. Ladder cages electrically driven gear, with a reaction force on the fixed rack uprights, ladder cage rails for vertical movement along the column. Its columns made into a standard section length of the upper and lower sections can be interchanged according to the required height to the construction site for assembly, generally erected up lOOm, for up to 200m at high-rise building construction. Elevator can be installed by means of its own electric boom assembly at the top of the construction site can also use the crane and other lifting equipment assembly. In addition, as the ladder cage and counterweight are arranged symmetrically, so overturning moment is very small, the column passed mural firmly connected with the building structure, so reasonable and reliable force.

Several important stage when used concrete mixer truck

Concrete mixer growth process

4 to 6 years of concrete mixer "Menopause"

Spend 4-6 years, concrete mixers, has gradually into the "menopause", as people enter the "Menopause" angry love, as in "Menopause," the concrete mixer, the point of the question is a common practice, as many parts of the car are start aging, often showing oil spills, leaks, small problems is endless. Savvy owners will take advantage of the beginning of the transfer period, the car of this period both to a better price, but also those of all the training and preparation of the problem is about showing others.

Concrete mixer 6 to 10 years of "old age period"

Concrete mixer at this stage, like six or seven year-old man, "three hundred sixty-nine illness, ailment every day", the car of this period, anything can be bad have been bad over the center. During this period, the owner is necessary to enhance the conservation of concrete mixer, regularly change wearing parts, the owner needs frequent repair station or conservation center to check the condition after the car out of the bus in front and take all necessary to do a routine inspection and maintenance work.

10 to 15 years concrete mixer "risk period"

Concrete during 10-15 years, will be in a "risk period" at any time "dying," the risk. Concrete mixer this period, it is best to stay in the garage owners convalescence, or sent directly to the waste station to sell scrap metal.
