There are many types of sprinklers, which can be classified by type, purpose, capacity, discharge standard, and chassis. The two most common classification methods are classified according to chassis brand and tonnage level. From the functional differences, it can lead to a great difference in the actual utilization. The tonnage of the sprinkler is related to the actual use. Today Xiaobian will introduce how the sprinkler is classified according to the tonnage.
The tonnage of sprinklers is mainly distributed in the following five levels: 2-3 tons, 4-4.5 tons, 6-8 tons, 9-15 tons, and 18-20 tons.
First, 2-3 tons, 4-4.5 tons, 6-8 tons of these levels of sprinklers are mostly used in engineering maintenance and highway construction, according to the actual needs of the operation schedule, tonnage from small to large, more selective. One of the most representative is the 4-4.5 tons of sprinklers, including Dongfeng Ruiling Sprinkler, Dongfeng Little Dolika Sprinkler, and Futian Times Light Truck Sprinkler. The tonnage-class models are equipped with engines of 90 horsepower or more. The vehicle carries less but has high stability and is durable.
Secondly, the main Dongfeng Dolika greening sprayer in the 6-8 tons of sprinkler trucks is the mainstay. The Dongfeng Doolika sprinkler has done enough to enhance the humanized driving experience. For example, the direction of hydraulic pressure is added, and the new low wind resistance The streamlined flat cab and so on.
Three, 9-15 tons of sprinklers can be described as Dongfeng Pingtou series a dominant market position, at this level Dongfeng to the Dongfeng 145 green sprinkler and Dongfeng 153 sprinkler two classical chassis, configuration from the basic 145-level 9 Ton rear axle with 9.00 tires, to 153 level 10 ton rear axle with 10.00 large tires. The engine can choose Cummins or Yuchai, and the horsepower is above 140. There are many types of these two models, and the selectivity is relatively large. The Dongfeng 153 sprinkler is also known as the Dongfeng 13-ton sprinkler.
Four, 18-20 tons of sprinklers are mainly divided into economic and practical Dongfeng Shuangqiao sprinklers and luxury Dongfeng Tianlong sprinklers two, the price from 200,000 to 248,000, a larger span.
Editor's Note: The last Xiao Bian wants to add some issues that should be noticed during the use of the sprinkler: The sprinkler should be as close as possible to the operating point. After the water in the tank is spilled, the driver should promptly push the power take-off handle forward. That is to say, the pump will stop running.
Some of electric parts for Tower Crane:
1. Electric motor: Tower cranes use electric motors to power the lifting and rotation mechanisms. These motors convert electrical energy into mechanical energy to move the crane's various components.
2. Control system: Tower cranes require a sophisticated control system to manage the movement and operation of the crane. This includes controls for lifting, lowering, slewing, and trolleying.
3. Limit switches: Limit switches are used to set the maximum and minimum positions of the crane's various components. They help ensure safe and accurate operation by preventing the crane from exceeding its designated limits.
4. Power cables: Tower cranes require heavy-duty power cables to transmit electricity from the power source to the crane's electrical components. These cables need to be durable and capable of handling high voltage and current.
5. Circuit breakers: Circuit breakers are essential safety devices that protect the crane's electrical system from overloads and short circuits. They automatically interrupt the electrical current flow when a fault is detected, preventing damage to the crane and reducing the risk of electrical fires.
6. Transformers: Transformers are used to step up or step down the voltage of the electrical supply to match the requirements of the tower crane. They ensure that the crane receives the correct voltage for optimal performance and safety.
7. Sensors: Tower cranes often incorporate various sensors to monitor and control different aspects of their operation. These sensors can include load sensors, wind sensors, angle sensors, and anti-collision sensors. They provide crucial data to the control system, helping to ensure safe and efficient crane operation.
8. Emergency stop switches: Tower cranes are equipped with emergency stop switches that can quickly shut down the crane in case of an emergency or safety hazard. These switches are strategically located and easily accessible to crane operators.
