LBU-50-30

Drilling rigs of the LBU-50 family are intended for drilling of wells of different function when performing construction, technical, hydrogeological works and water supply wells, at engineering researches including CPT, SPT and geological surveying.

The LBU-50 drive is carried out from the transport base engine via the PTO. LBU-50 is mounted on the chassis of various trucks, including ZIL-131, URAL, KAMAZ. The rig can be mounted on the clients chassis with corresponding power intake value (kW), shaft rotation frequency (RPM), rotation direction.

Mobile rotator in combination with the powerful hydraulic feeder allows to create considerable axial load of the rock cutting tool from the first meters of drilling.

The LBU-50 rotator design provides possibility of its diversion from a well axis for performance of hoisting operations, installation of casing columns and realization of free-fall boring with use of the boring winch.

Drilling rigs of the LBU-50 family possess high rates of technical characteristics and modern constructive decisions:

- frequency rotation range of 14-220 rpm allows to use various boring tools, including hard-alloy crowns, bladed and core chisels
- carriage course of 3900 mm makes it possible to use elements of the bottom hole assembly and drill pipes with a standard length of 3200 mm - 3500 mm
- hydraulic mud pump or compressors allow to smoothly change their performance
