  • Grease Is Key To Maintaining You Hydraulic Rock Hammer

    When it comes to maintaining your hydraulic rockbreaker, absolutely the most important thing you can implement into your routine is lubricating the tool. This preventative maintenance routine can you save you time and money.
     
    Manual greasing of your hydraulic hammer is often a real pain. However proper lubrication is critical to extending its life. It’s a painstaking but straightforward task to be repeated every two hours of continuous use, or when the tool becomes dry and shiny. Failure to grease regularly will significantly increase wear rates and reduce the lifespan of your tool, bushings, and front head components.
     
    HOW TO GREASE YOUR HYDRAULIC ROCKBREAKER
     
    Greasing Hydraulic Breaker Hammer
    Firmly pressing the tool up inside the hydrualic rockbreaker prevents excessive grease from entering the impact chamber. Excessive grease in the impact chamber will cause a hydraulic lock, which depending on the amount, can cause a lack of power or immediate seal failure and ingression of grease into the hydraulic system when the rockbreaker is fired.
     
    The hydraulic hammer must be in a vertical position to grease, with enough down-pressure to push the tool up inside the housing.
    Grease until clean grease oozes out around the tool and retainer pins.
    Grease hydraulic hammer after every two hours of continuous use, or when the tool appears shiny where it rides inside the front head.
    Remember to use the manufacturer recommended grease. We recommend a the SLYM chisel paste or equivalent to lubricate all SLYM's hydraulic rock breakers.

  • How to select the appropriate steel chisel

    All of steel chisel are subjected to wear and tear, become dull, so that even dull hammer to reduce their service life. A dull steel chisel will greatly reduce productivity, you must re-processing(sharpen).
     
    The degree of wear and tear directly depends on the abrasion of the tool used inside of the minerals. Especially in the rock, quartz, or longevity stone calcium aluminum silicate content reaches 10% even under more circumstances it will cause a lot of wear and tear.
     
    If the rock does not contain these substances, then the result of wear and tear is likely to be part of the steel chisel and liner contact.

    镐钎_rod
     
    There are three special steel chisel designs.
     
    1. Cone steel chisel
     
    This steel chisel shapes like a pencil tip, and is often used to pierce and object and penetrate the tool. In other words, even very hard objects can also be seprated by splitting power of point cone. Including, such as no reinforced or slightly reinforced concrete, sedimentary rock, and high hardness, seamy rock and so on.
     
    Characteristics
     
    1)The energy provided will have a very marvelous penetration when through point.
     
    2)Split power being transmitted around.
     
    3)No reverse
     
    2. Flat Steel chisel 
     
    These tools like stone mason’s chisel and are most widely used in the hydraulic hammer. Flat chisel works like cone chisel. Under the same working conditions, flat hammer is more wear-resistant. Because their shapes are more suitable for handing the reinforced materials, and thus flat chisel can smash the reinforced concrete better. So they are also recommended to break the heavy reinforced concrete, in addition, also widely used in sedimentary rocks, and the rock cracks of high hardness rocks.
