Dismountable Large Diameter Engineer Drilling Rig: The drilling rig Model INTGS-1A is a dismountable rig that can drill large diameter foundation pile holes in the Quaternary overlying stratum and common rocks. The rig is widely used in foundation construction of bridges, highways, multistory buildings. Equipped with mud pump, the rig can be used for positive circulating drilling. If equipped with pump station, drilling tools and equipment, the rig can also be used for negative circulating drilling with mud or drilling with air. The rig is structured in dismountable components, all the main components(electric motor, transmission box, main hoist, assistant hoist, rotating table and drill tower) can be installed onto the dismountable base plate. Transportation and handing is easy owing to its dismount ability. At the rig base there equipped an arc-shaped hanger for rolling or sliding mechanism. Together with proper rollers the rig can be moved inside the site with the aid of the assistant hoist. Our "Huanghe" drilling rig's base plate is installed in the rig and the main hoist is a planetary transmission mechanism with reasonable and reliable performance, safety and endurance. The rotating table, hoist transmission and motor starting cabinet for the rig can be ordered separately.Drilling depth 70m Diameter of holes 1500-2000mm Driving drill rod 108×108×5800mm Drill rod in the hole 89×5000mm Tension Force of Main Hoist 40kN Tension Force of Assistant Hoist 20kN Through hole diameter of rotary table 505mm Rotation speeds of rotary table Positive62,24rpmNegative 64,25rpm Power (electric motor ) ModelY225M-4 45kW Recommended Mud Pump 3PN Dimensions(Wording Conditions) 5870×2560×9620mm Weight of rig 6t
