Rising and falling aerial vehicles
Definition: The lifting mechanism of the aerial working platform is a crane type, and the operating mechanism is a high-altitude vehicle of a tire type vehicle.
Scope of application: Suitable for high-altitude operations of large-scale engineering projects.
Lifting arm aerial work vehicle operation rules
6. The choice of parking position should be a solid ground. The inclination of the vehicle should not exceed 3° and the warning flashing lights should be turned on.
7. Working height and wind power (Baufort);
Wind 6 or below suitable height 10 meters below the operation;
Wind power level 5 can work below 11~20 meters;
Wind 4 and below suitable height 21 to 30 meters below the operation.
8. Start the oil pump, step on the clutch of the car, pull on the handbrake, and the transmission is in neutral gear, and pull the hydraulic oil clutch clutch lever to make the hydraulic oil pump work.
9. After the hydraulic pump runs for 2 to 5 minutes, it can operate the handles of each movement.
10. The operation of aerial vehicles should be trained and hold personnel responsible for operational licenses.
11, the operator must concentrate on the prevention of misuse and strictly prohibit alcohol after the operation.
12, first put down the legs, if necessary, put the pad under the leg of the leg to ensure that the vehicle is in a horizontal state.
13. When operating the handle, it should be steady, and do not swift and swift in order to avoid the inertial swing of the working arm and the accident.
14. Operate strictly in accordance with the technical parameters and operating ranges specified by the equipment.
15. The staff on the operation bucket (platform) should wear a seat belt.
16. When raising and lowering the work bucket (platform), the upper and lower arms should be alternately operated to ensure that the bucket (platform) is in the best rising radius. It is forbidden to use the working arm for other purposes.
17. During operation, the operator should pay attention to the safety distance of the bucket (platform), arms and high and low voltage wires, telephone lines and buildings, big trees, billboards, lighting and other objects.
18. The on-duty driver is responsible for the ground and pay attention to the safety protection of the traffic.
19, the use of the operating height of 25 meters above the truck, in addition to setting up safety signs and guardrails, the ground guardian in addition to the driver, but also set up 1-2 people responsible for strengthening the guardianship.
20. During the operation process, if there is abnormal noise in the hydraulic system or sudden leakage of oil, the work should be stopped. Only after the inspection or repair can the work be continued.
21. When the hydraulic system fails and the working arm is unable to move, it should try to evacuate the work personnel on the work platform (platform) and notify the professional maintenance personnel to handle it.
22. After the operation is completed, the operation bucket (platform), the operation arm is reset, the support leg is retracted, and the hydraulic oil pump is disengaged, and the hand brake is released to start driving.
other
23, high-altitude operation bucket (platform), arm and leg should have reflective safety signs.
24. The aerial vehicles shall be equipped with two triangular (tire) skids and four outriggers. 25. The vehicle should be equipped with a horizontal sign.
25. The most common aerial platforms currently on the market include: Dongfeng Aerial Work Trucks, Liberation Aerial Work Vehicles, Ao Ling Aerial Work Vehicles, Qingling Aerial Work Trucks, Jiangling Aerial Work Trucks, and JAC Aerial Work Trucks.
The use of aerial vehicles:
Mainly used in electricity, communications, street lamps, traffic police, highways, cable television, ship repair, construction, gardens, advertising, photography, large enterprises and other industries

Closed Cooling Tower
Why say closed cooling tower is energy saving and environmental protection equipment, more and more users are using this kind of equipment to replace the original equipment (open tower), we can through data analysis and comparison, the two energy data accounting can be obvious. Energy consumption is basically two major aspects, one is water, the other is electricity. Both are energy costs that no cooling tower can escape, unless you leave the equipment on.
First of all, look at the consumption of water. Water is generally consumed in two aspects. One is the flying overflow after spraying, and the other is the evaporation consumption of water.
Let's look at the open cooling tower, the spray water of the tower is basically between two and three percent of the overflow rate, if we according to the daily operation of 10 hours, excluding holidays, 280 days of operation. According to the actual open cooling tower flow of 6000 cubic meters per hour to calculate. 6000*2%*10*280= 336,000 tons of water, and the same closed cooling tower, its spray flying overflow is very small, because after all, the spray work is carried out in the tower, almost can be controlled in a few thousandths, we calculate according to 5 thousandths, the same is 10 hours of work, 280 days a year operation, To achieve the same cooling amplitude is basically 4,500 tons per hour of closed cooling tower is enough, then the calculation results: 4,500 *0.5%*10*280= 63,000 tons, it is not difficult to see, because of the different design structure caused by the waste of spraying water resources, more than 200,000 tons of terror. The bigger the pool of the open tower, the more wasted water, because the evaporation area increases, and the closed cooling tower has no pool, so the consumption here is zero. Judging from the price of a ton of water, just such a equipment, a year to solve the capital of hundreds of thousands of enterprises.
Let's look at the comparison of electric energy, electric energy is not different, because they are all through the same power equipment to operate the equipment, the power of the two is similar, the running time is the same, basically the energy consumption is about the same.
To sum up, for the closed cooling tower energy saving accounting can be strong to open the tower out, and, today are advocating energy conservation and environmental protection, this is the general trend, so the closed cooling tower is more and more favored by the majority of users.
