★ COMPANY INTRODUCTION 

GRANDPLAN drilling is engaged in designing and manufacturing of various DTH drills, the main categories include down-the-hole drill like GP590, GP580, GP358H(D), CL351, CM458(D) etc; As well as impact type well drill like GP200, GP300, GP400, GP500, GP600, GPS800, GPS1200 truck-mounted well drill and other impact type drill etc. GRANDPLAN down-the-hole drill is applied to earth-rock blasting engineering in large and medium-size mine, national defence engineering, as well as underwater rock drill blasting work of harbour channel etc. GRANDPLAN well drill is applied to large diameter and deep hole work in drilling wells, geothermal air conditioning drilling etc...
We have mature after-sale service department, and can provide powerful support and any other after-sale service to our users during operation. Our products are widely used all around the world with very great name.

★ GP800 multi-functional crawler well drill brief introduction 

GP800 multi-functional crawler well drill is new type, efficient, multi-function hydraulic water well drilling. Mainly used for drilling water well, 
monitoring well, dewatering well, relief well, the gas layer mining and other probe holes project. 

In stone drilling, DTH hammer is applied in the operation, slag is discharged by air pressure and the feeding efficiency is ten times higher than traditional rotary drilling rig.

Cutting drilling or cone drilling can be used in the unconsolidated layer, and the slag can be discharged by the form of mud, can also use the impact follow-pipe 
drilling method, the slag will be discharged by the air pressure, this model is suitable for drilling in complicated geological conditions. 

The maximum drilling depth is 800m, the drilling diameter is Φ140mm-450mm.
