Self-propelled core drill UKB-5C intended for boring of vertical and inclined (up to 70 ) exploration holes for hard mineral wealth with the depth up to 800 meters using diamond and hard-alloy crown bits
Drilling rig UKB-5C applied at the open air, all-the-year-round in the areas with temperate climate with the atmospheric temperature from minus (-)40C up to plus (+)40C.
Drilling rig UKB-5C provides:
1. drilling of exploration holes by rotation drilling method, curf or continuous face, as well as holes drilling using rotative drill and down-the-hole drill;
2. bottomhole cleaning out of drilled rocks by drill fluid
3. cores sample withdrawal with the help of retrievable core receiver or by lifting up whole drilling assembly to the surface.
4. lifting (lowering-in) of boring frame, placing it to the required boring angle by hydraulics
5. mobile relocation of drilling rig from one place to the other.
Drilling rig UKB-5C is made with the high-flotation chassis KRAZ-255 with metal warmed cabin or on the base of other KRAZ-6322, KRAZ, 63221 models. Also the equipment can be installed to the base of MAZ-7310 with increasing of drilling depth up to 1200 meters.

Self-propelled core drill UKB-5C ( on the truck chassis) presents complex of drilling and power equipment, intended for boring of vertical and inclined exploration holes.
The main component parts of drilling rig UKB-5C are transport station (base), boring mast and body, which is designed for equipment storage and workers placement on bed weather. To increase working area of boy there are installed 2 retractable bins. The retraction of the bins is controlled by hydraulic system and retraction mechanisms.
Hydraulic system provides raising of mast and placing it to the required drilling angle, placing of the working ladder, as well as installation of machine from transit condition to operation position and backward.
In working position mast is fixed by wind safety braces.
The installation works for setting the machine from transit condition to the operation position can be done and controlled from the mounting pad. There is safety guard on the mounting pad and on the roof.
The power supply for drilling rig UKB-5C is made from the external power supply source with voltage 380 V. Required power - 60 Kwt.
