These versions are worked out on the base of two-section track carrier DT-30P. Hydromanipulator, welding unit, extraction pump are installed on the first section; excavator equipment – on the second one.

They are intended for excavation, loading – unloading and construction work at the dispersed units on the difficult ground. DT-30KE excavator has 3 hydraulic operated outriggers. DT-30PKE1 has easy demountable and collapsible body sides of the second section (amphibian version).

Design of DT-30KE and DT-30PKE1 emergency repairing complexes is peculiar. These machines combine equipment for preventive and emergency work at the oil-and-gas extraction unit and high-speed passable two-section chassis. Besides that there is a covered sealed body with welding unit and extraction pump on the first section. Such emergency repairing complexes are more effective in areas difficult of access than existing in our days wheel and track vehicle, what is more, they replace several machines of different purposes.
