Dongfeng truck crane we also call the truck crane truck, mainly used for a variety of loading and unloading, installation lifting operations, such as: field crane, rescue operations, we see more at the station, port, warehouse, Work on sites such as construction sites. The operation speed of such large cranes is relatively slow, because the requirements for accuracy are relatively high. Therefore, there are certain requirements for the operation of the truck cranes. Specifically, what are the operational requirements? Let's take a look with Xiaobian! According to different needs, different lifting operations require the use of different lengths, tonnages of cargo compartments or cranes to achieve rapid lifting, high efficiency, and energy conservation. If the lorry master is very knowledgeable about his vehicle, he must clearly know the function and limitations of the car, with its own special operating characteristics, in order to be able to operate the most accurately, of course, before lifting the manual. The relevant regulations must also be studied because high-altitude work on the site is a more dangerous job to avoid dangerous events. Driving crane trucks on professional technology needs to be able to calculate and determine the actual lifting capacity of the lorry crane truck, to be familiar with the lifting chart of the lorry crane truck, and to regularly inspect and maintain the lorry crane according to the requirements of the manufacturer. Transport carrying capacity. In the operation, it is necessary to make a detailed record of all the inspections, maintenance, and on-board crane transport and maintenance at any time during the detailed log operation of the truck-mounted crane transport. In the lifting operation of the truck, it is necessary to find the load in time and install the lock, and then find out where the load is placed. Although the operator is generally not responsible for determining the weight of the load, if the operator does not verify the weight with the supervisor, he will be responsible for all the consequences of the lifting process of the vehicle, so the operator needs to Be cautious and can timely consider all the factors that may affect the lifting of the vehicle and adjust the lifting weight in time. Through the above introduction I hope to help you, the operator in the driving process and the signal must always maintain good communication, so as to ensure safe and stable operation, more relevant issues you can give Xiaobian message.
Melt-blown fabrics have generally the same applications as other nonwoven products. The main uses of melt-blown nonwovens and other innovative approaches are as follows.

Dongfeng Truck Crane Operation Requirements
300mm Meltblown Spinneret for Meltblown Medical Mask Nonwoven Fabric Producing
Melt-blown spinning is to blow a molten polymer through a high-temperature high-speed gas to refine the polymer into a filament to form a nonwoven fabric.
1. Stainless steel wear resistant and corrosion resistant.
1) :Meltblown Die Head Can be Customized within 100-3200mm
Features
Optimized design, hole number encryption, high output, reduced production costs
The number of holes per spinneret is 13% less than jier. Less of holes, then less of yield.
L/D ratio (small hole length): Common 1:10, Our Company 1:15, our length is 50% longer than common spinneret, the top of the spinneret is strengthened, not easy to deform, ordinary hardness HRC (25-28° ),jier hardness HRC (34-38 °) has a longer service life.
Common spinneret use 'Electric spark punching and manual drilling'. Shortcoming: The hole is not straight, multi-slanted hole, hole wall is not smooth, the verticality and straightness are not good. Our company uses CNC high-speed machining center processing, the holes of our product without slanting holes, verticality and straightness is very good, There will be no serious phenomenon of "spot" floating wire caused by merged wire and broken wire.
Due to the structural factors of the conventional spinneret, there is often uneven discharge. Our company adds static mixing deflector to the melt chamber channel for the defects of the spinneret., so that the melt is evenly mixed in all parts of the chamber while the air duct structure data is improved. Make the quality of the products more perfect.
Product Advantages
Melt blown die head
1. Encrypted holes, more output
