Gamzen plast pvt ltd ensures varieties of construction and pilling machines. Well sinking grab is a part of those products. Well sinking grabs are widely used in the construction of foundations and trenches because of their undoubted strength, simplicity and low running cost, especially on hard ground. Unloading is done by taking advantage of the grab body`s weight, which when released by the rope, descends with considerable force, thus helps detaching material from the jaws.
