  Usually,we are easily to see that wheel [pulley] type of Hammer Grab is popular to use at the job site. And we've ever had some experience for facing with some problem of its repair and maintenance.

Why it causes such problem?

   The reason is that the wheel type of Hammer Grab is consisted of 6 wheels, surrounded by wire, to close & open the Bucket and is so complicated. When it impacts on the soil, Wire can be separate away from the wheel, both Wheel & Wire are wearable and consumable due to moving. What's more, wheel is often borken down and can be out of order as occurring the dirty substance.

Why We need it ?

   Our Hammer Grab doesn't use such Wire and the Wheel, and can reduce such a mechanical defalut, occurred by the wheel type.


HAMMER GRAB FEATURE

1. Easy to open and close the Bucket

   As drawing says, it is made of the Slide Box (3), STOPPER and CHAIN, in  the upper part. This slide box is specially designed in order to move up and down.
And also, it is very easy to open and close of bucket, because of connected X type of rod with arm type.

   2. Durability
 
      Compare to wheel type of hammer grab, it is designed and made strong  
    for impact. As the result, the minor breakdowns are rarely happened, 
    and also you don't have to spend your precious time & cost more for repairing
    & maintenance of it.

    3. Improved bucket capacity
 
       When free fall of hammer grab in casing, the opened bucket of wheel
     type hammer grab could be closed little bit due to mechanical default.
     However, our hammer grab doesn't cause such problem because square slide
     support the X type of rod as opened bucket.

   4. Saving cost

       Compare wheel type of hammer grab, you can save more cost with high 
     performance at the job site.Because the Rod type Hammer Grab is more
     powerful and improved bucket capacity. Compare wheel type hammer grab,
     internal structure of rod type hammer grab is organized simply without wire and
     wheel. As result, there is rarely occured minor breakdown. So you can save
     the cost of repairing and maintenance of it.
