Engineering drilling machine must use drill pipe, and joint pipe is indispensable within the engineering drilling machine, so construction personnel must give consideration to. For the whole process of the joint pipe in engineering drilling machine also needs to understand.Henan Daswell Machinery is a professional manufacturer of mining machine for almost 30 years in China. We are dedicated to supplying our customers with best service and products, our major products include:electric cement mixer for sale,planetary concrete mixer supplier,portable diesel concrete mixer,If you are interested in our products, please contact us freely: sales@daswell.com The joint pipe operating factors of engineering drilling machine: once the rotating mind of engineering drilling machine goes lower towards the cheapest point Diesel concrete mixer, promote the turret to allow the drill pipe’s wrench mouth of engineering drilling machine has the capacity to place the wrench, and shut the outcome device. Place the plug wrench towards the drill pipe wrench of engineering drilling machine and fall the turret, to be able to result in the fork’s finding surface over the centralizer pipe lining. Allow the turret rotate even though it is gradually lifting, before the engineering drilling machine’s joint and drill pipe release completely, and drill pipe dangles around the fork from the centralizer now. Lift the turret SICOMA Twin Shaft Concrete Mixer, before the drill pipe is fully suspended and outside change to make use of the wind to blow engineering drill pipe cleanly.
