150M Depth Core Drilling Rig

Main Features: 1. Very powerful at soil, sand, hard rock, etc. land condition. 2. Three kinds drill bits (three-wing bit, alloy bit and diamond bit) available for your choice, which can drill both soft and hard ground, especially diamond drill bit effective in drilling hard rocks. 3. Hydraulic control system for greatly improving the working efficiency, saving labor force. 4. Mounted wheel or trailer, can be hauled easily by car or tractor, convenient to transport. 5. Power can be diesel engine or electric motor, as per your request. Advantages 1. This machine gained 3 national practical new-type patents invention. 2. To be equipped with hexagonal vertical shaft and hexagonal drive drilling rod, with strong rigidity and big transfer torque. 3. To be provided with cone plate friction clutch, being facile to operate, with big transfer torque. 4. To adopt rolling bearing type hoist, with wide brake band and big lifting capacity. 5. To be equipped with speed reducer and sludge pump, being integrated structure. 6. The entire machine is featured by strong adaptability, high motive power, low cost and broad compatibility. 7. To be provided with hydraulic control pressure feed mechanism for the purpose of improvement of construction efficiency. 8. To use hydraulic control well head displacement mechanism for enlargement of initial hole diameter.

Particularly recommended 1. 53*59 drilling rod adopted,high rigidity and strong delivery torque. 2. The machine is equipped with national patent technology: taper clutch,with characteristics of strong transmission torque,easy operation and free maintenance. 3. For the winch,we use large module planetary gear and add supporting frame,greatly increasing hoisting and braking ability of the winch. 4.Vertical spindle are fixed by four groups of bearings to ensure that the rotary machine is rigid enough for gravel layer and other complex geological conditions. 5. We are the first one to equip mud pump with the flow 160L/Min in china so that it will save cost and also make the machine compact,mobile and lightweight. The application of drilling rig machine: ST-100 drilling rig is mainly used for geological general investigation and exploration,road and tall buliding foundation exploration,kinds of hole in concrete structure,river levees,subgrade grouting hole drilling and direct grouting,civil wells and earth temperature central air-conditioner,etc.

ST-100 core drilling machine is a light type core drill rig at high speed with hydraulic feeding. 1.With hydraulic feeding device, elevated drilling efficiency, reduced labor strength. 2.The rig is equipped with an upper spherical jaw holding mechanism and hexagonal Kelly, which can be replaced without shutdown, high efficiency, safe and reliable. 3.A hole bottom pressure gauge is mounted indicating the pressure in order to control the status inside the hole. 4.Compact structure, small volume, lightweight, high detachability, easy transportation and suitable for the operations in plains or mountain areas.
