Expert assessment:
Excavation (drilling) function: different specifications of buckets can be selected, which can be broken tightly on the hard road, and the digging depth is not less than 3000mm; Optional drill pipe with a drilling diameter of 450mm and a maximum drilling depth of 3m can be installed to achieve drilling function; Lifting function: can lift not less than 1.2t prefabricated foundation. It can be used for lifting operations with matching tools. Can be selected according to the construction technology; Grab rod function: It can meet the grab and transfer function of 15m and below pole. Vertical pole function: large lifting height, to meet the needs of 15m and below pole; Backfill function: the mining arm has a two-stage rotation function, which can flexibly adjust the position for backfill; Tamping function: the digging arm has the function of quick head replacement, replacing the tamping hammer head for the pole backfill and tamping; L-wheel integrated function: with tire and track two modes of running, adapt to different environmental requirements; Safety protection device: with limit alarm, lighting and warning light functions for night construction, anti-collision detection of main and secondary working devices, vertical pole verticality detection, pit depth detection and visual display functions.
