FIELD: construction, methods or apparatus for placing sheet pile bulkheads, piles, mould-pipes, or other moulds by screwing down, namely for electric plant mounting.
SUBSTANCE: device comprises frame, guiding pipe with clamp, reduction gear with gear-wheels and bearings. Guiding pipe, driving gear-wheel and bearings are made as two sectional parts and provided with hinges from the first sides and with locks from the second sides thereof to join up all parts in single rigid structure. All hinges are coaxially arranged.
EFFECT: extended field of screw grounding electrode usage during grounding devices installation, increased structural simplicity, decreased weight and costs, increased reliability and operational safety, possibility of device usage in the case of power source absence or in territories unsuitable or unfavourable for another equipment usage.
