URB 2A2

Description

* The price without the cost of the chassis.
The drilling rig URB-2A2 mini 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 carried out by rotational method with washing or blowing of the well or augers.
The rig is mounted on the chassis of the Amur-531300, Ural, KAMAZ, MTLB and is driven by the engine of the car. 
Moving along the mast, the hydraulic drive rotator is used for drilling, augmenting the drilling tool for work and performs, together with the hydraulic lift on the descent (lifting) of the tool and its supply during drilling. The rotator is moved along the mast with a hydraulic cylinder and lifting system. 
Management tool is hydroficated drilling rig and is fully focused 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. 
A distinctive feature of the installation in comparison with the standard URB 2A-2 is less weight and dimensions, which allows you to install it on the chassis with a lower load capacity.
