DW(06-20)-300/100(D)

The standout feature of this new type single hydrauic prop is that, compared to conventional single hydrauic props of the same model,itis stroke iincreased by over 70mm.In addition to the extended strokeit also boasts the following chara

1.nternal Cvinder Seal Desion: This innovative single hvdrauic prop adopts an cvlinder inner bore sealna mechanism. completely eliminaina the shor.comings of suspended props that use a sliding cylinder seal, such as shorter lifespan and dificult maintenance

2 Outer-Wrapped Base: The base features an outeer-wrapped design, which not only increases the stroke but also expands the load-bearing area of thebase, effectively protectina the bottom of the oil cvlinder and enhancing its rigidity

3.ntearated rod and Piston: The rod and piston are desioned as a single unit,remoyina potentialleakage poinis between them and ansuing more reliabiloperation.

4.20% Higher Support Strength: Our single hydraulic props provide a 20% increase in support strength compared to conventional models

新型大行程单体液压支柱的性能特点

This pillar is a new product developed by our company. lt has the advantages of thesame stroke, large bearing capacity and wide range of application, as well as the followingcharacteristics:

1. The Piston Seal of the inner hole of the oil cylinder is adopted to make up for thedisadvantages of high maintenance cost and short service life.

2. The valve body is located in the fixed position of the oil cylinder. The three-purpoeValve does not rise with the increase of the valve column.

3. The base adopts the outsourcing type, which increases the bearing area of thebase and effectively protects the bottom of the oil cylinder from deformation.

4. The double cvlinder structure is adopted at the bottom of the prop, which enhances
the force strenath of the cvlinder and improves the stability of the prop.

5. This type of prop has the same big stroke as the suspension type prop, because thesuspension type prop is the hand handle body and the live pllar seal, when the prop strokeis big, the hand handle body is easy to leak the liquid, but this type prop uses the oil cylin-der piston seal, when the prop is used with large stroke, the stability is better, the anti- bias load capacity is stronger, and the security is higher.

6. The utility model can repair and replace the base simply by disassembling the baseand the Piston seals are convenient and auick in maintenance, and the maintenance costis low.
