Characteristics of DW single hydraulic prop supply DW single hydraulic prop

Description :

　　Product characteristics of DW single hydraulic prop

　　1. The work schedule is large, especially suitable for working faces with large changes in underground roof height.

　　2. The pillar adopts inner hole sealing, which is resistant to bumps underground and has a wide range of applications

　　3. Never break. Friction welding is used, and the weld seam does not break.

　　4. The pillar adopts a new type of sealing device, which eliminates the leakage point between the DZ type pillar piston and the active pillar, ensuring safe and reliable use.

　　5. Can provide horizontal support.

　　6. High strength, without bending.

　　Introduction to DW Single Hydraulic Prop

　　DW single hydraulic prop is a constant resistance prop, which can be used in conjunction with various top beams or as the main prop. It can be used for general mechanized coal mining or blasting mining face support, as well as for comprehensive mechanized coal mining face end support or other temporary support.

　　DW single hydraulic support and metal hinged top beam are used in conjunction for the general mechanized blasting mining face and comprehensive mining face ends or temporary payment roof in coal mines. They are suitable for working faces with coal seam dip angles less than 25 °. When certain measures are taken, they can also be used for mining faces with dip angles of 25 ° -35 °. This series of single hydraulic supports has good stability and outstanding technical performance advantages. The single support height of high-end general mining faces in coal mines has been increased from 2.5 meters to 3.5 meters. Coal seams below 3.5 meters can achieve full height mining in one go, and can also provide end and advance support for working faces with coal seam thickness below 4.5 meters

　　The significance of DW single hydraulic prop model

　　For example, DW25-250/100:

　　D - represents a single hydraulic prop

　　W-represents external annotation

　　25- is the height of the pillar

　　250- rated working resistance of the pillar

　　100- Diameter of the oil cylinder for the pillar
