The drilling rig URB 2A2 without chassis KamAZ, without pump, without compressor
One of the most vostrebuyemy installations of our production of LLC Burovoye mashinostroyeniye, is - the URB-2A-2 drilling rig on the Urals-4320 chassis. Onboard this installation there is all the most necessary for performance of the numerous tasks connected with drilling from 1 meter to 300 meters in depth assembly of the best quality, differs in high efficiency and ease in operation. It is one of types of popular installations in the market of boring production.
The mission of the URB-2A-2 Drilling rig is a drilling of geophysical and structural and search wells on oil and gas, investigations of fields of solid minerals, construction materials and underground waters, engineering-geological researches, drillings of water and explosive wells.
The URB 2A2 drilling rig is intended for drilling in the rotary way with washing or a purge of a well, or screws.
When drilling, and also when building the boring tool the mobile rotator with a hydraulic actuator which moves on a mast by means of a hydraulic cylinder and talevy system and performs along with a hydrojack work on descent or raising of the tool and its giving when drilling is used.
Installation of our installation is possible not only on the Urals-4320 chassis, but also on ZIL-131, GAS - 3308, KAMAZ-43114, and also MTLBU. The all-wheel drive chassis "Ural" is chosen most often because it is one of types of the chassis which possesses the best passability - the most important point during the work in the remote district.
We always offer various options of a complete set of the drilling rig and we try that the drilling rig which is most adapted under your tasks as a result turned out. The cost of installation will depend on the chosen complete set from the offered options.
Installation complete set:
- boring pumps: NB-50, NB4-160/63 (with a transmission or without it)
- compressor: 4VU1-5/9M32, KV-12/12, Airman 390S
- generators: BG-16 and BG-30, GD-4006
