URB 2A2

Description

* The price without the cost of the chassis.
The drilling rig URB-2A2 is designed for drilling geophysical and structural exploration wells for oil and gas, exploration of solid minerals, building materials, and groundwater, engineering-geological surveys, drilling of water intake and blast wells. Drilling is performed by a rotational method with washing or purging of the well or augers. 
The unit is mounted on the chassis of the Amur-531300, Ural, KAMAZ, MTLB and is driven by the car engine. 
Moving along the mast rotator with hydraulic drive is used in drilling, augmentation of the drilling tool on the job and performs together with the hydraulic lift work on the descent (lifting) of the tool and its supply during drilling. The rotator is moved along the mast with the help of a hydraulic cylinder and a hoisting system. 
Management of drilling rig tool is hydroficated and fully concentrated on the driller's console. On the remote are the control devices and regulators efforts to slaughter, feed speed and lift, and the frequency of rotation of a spindle of the rotator.
