ST 260 Borehole Drilling Machine Features
1, It is a high efficiency and multi-functional down the hole water well drilling equipment, It can be used to drill water well, agrecultural irrigation well, geothermal well and other type well holes. It is sepcial suitable for mountain area and rock stratum water sourcing project.
2, This machine can drill in different stratum, The maximum bore diameter can be 450mm.
3, This machine adopts big torque hydraulic motor for power head and brand diesel, big diameter hydraulic cylinders for the hydraulic control system. The brand diesel is protected by 2 levels air filtration systems and also can directly use the clean air from the air compressor.
4,Unique bump set design and centralize controlled operation system is easy to maintain and convenient for machine operation.
5,This machine adopts excavator crawler chassis and make the machine a high off-road performance, It also can be mounted on a truck to make it more maneuverability.
How to install the oil cylinder of the drill tower?
1. When the connecting pin can not be pulled out when the rotary locking connecting rod is removed, jog repeatedly to rotate left and right. 2. Expand the track to fully expand the track width. 3. Connect the upper mast and the middle mast. Loosen the fixing pin between the upper mast and the middle mast (the folded upper mast and the middle mast must be fixed together with this pin during transportation), extend the upper mast and pulley frame to the same straight line position with the middle mast, and use bolts to reliably connect the upper mast and the middle mast. 4. Connect the lifting anchor frame to the transverse fixed beam of the pulley frame with the piston rod of the pressurizing oil cylinder with a sleeve lock rope. Operate the handle (see the operating function of the handle). Extend the piston rod of the pressurizing oil cylinder to pull up the pulley frame, so that the pulley frame support is close to the upper end face of the upper mast, and reliably connected with bolts; 5. Connect the middle mast and the lower mast, pull out the main winch wire rope to the length that is enough to lift the drill pipe, start the machine operating handle (see the handle operation function), and slowly erect the mast to the vertical state. When the lower end face of the middle mast and the upper end face of the lower mast just lean together, stop operating the mast control rod immediately, otherwise the machine parts will be damaged, and then use bolts to reliably connect the two masts. 6. Take down the lower mast support rod 7, connect the pressurizing oil cylinder and the power head, adjust the mast to the vertical, extend the pressurizing oil cylinder to the vicinity of the power head, repeatedly expand and adjust the position, and finally install the pin connecting the power head and the oil cylinder, and tighten the baffle bolt beside the pin.
