It is mounted on a tracked track with a two-boom design. It is equipped with a hydraulic drilling system, is jam-proof, compact, maneuverable, and perfectly overcomes slopes. The diesel engine allows efficient use of fuel and reduces harmful emissions.
The installation is on a tracked track, electrohydraulic. It is used for drilling explosive holes, holes for anchoring in horizontal workings and inclined up to 10 degrees from the axis.
The size of the bores: diameter d = 38-52 mm, Cross–section - up to 20 m2, rock strength f = up to 16 on the Protodyakonov scale....
SBU-100-32 is used for drilling blast wells with a diameter of d = 110-130 mm. The maximum depth is 50 m. It is possible to change the drilling angle (0, 15, 30 degrees). These are mainly open-pit mining or construction sites (submersible pneumatic hammers are used).
Rock strength coefficients f=6....20 on the Protodyakonov scale....
URB-2A2 is one of the most versatile and unpretentious drilling rigs. It has a fairly simple design, high performance, and is capable of operating smoothly in any climate and in any weather. The temperature range is -40...+40 C.
The URB-2A2 is mounted on the ZIL-131 or URAL-4320 chassis, as they have improved cross-country performance. The work is carried out by the truck engine.

An installation with a hydraulic hammer has 1.5-2 times higher productivity compared to an installation with a pneumatic hammer. It is used in underground mines of ferrous and non-ferrous metallurgy.
The size of the bores: diameter d = 38-51 mm, depth h = up to 2.8 m. Cross-section 5-16 m2, rock strength f= 6-20....
It works well in areas with soft soil, as the structure exerts a low specific pressure on the soil.
Large digging depth, soil discharge and bucket casting distance. It is used for complex and extensive excavation work.
A dragline shovel can be forward or reverse. Each shovel has a different bucket volume from 20 to 168 m3.
