Handy Maxidrill is a hydraulic drilling mobile unit, totally independent, and suitable for vertical drilling on any inclined and in any type of rock.
Handy Maxidrill is made up by a drilling unit placed on the boom of a four wheels driver vehicle, is equipped with two hydraulic drifters, models Doofor DF40 o Doofor DF50, fitted out with an anti jamming device and mounted on two independent chain feed slides.
Hydraulic unit can rotate +/- 90°vertically, a +/- 20° vertical inclination and a +/- 15° horizontal inclination and it can have a 0,30 Mts. extension from the ground support without moving the boom.
The holes produced are vertically lined up by an indicator angle settled on the unit base and they can have a diameter between 22 to 45 mm. by the use of Integral drill steels - 22 mm. (7/8”).
Drilling unit has a telescopic boom shift with extension of 9,7 m. The presence of this boom gives the possibility of squaring the blocks situated over 9 m. respect to the place self-moving is situated. In order to make completely exploitable the sliding track of the drilling unit the half moving is equipped, in the front part, of two pistons that allow a +/- 250 mm. lateral translations The self moving shifting is made easier by the hydrostatic drive, four wheels driver in any conditions of the ground.
All the drilling and boom shifting operations can be effected by a remote control panel by radio operating on proportional controls of directional valves. Our module, constituted by oil filters, the heat exchanger and hydraulic compressor, is mounted on the back part of the self-moving in order to limit the encumbrance.
Drilling unit has been planned a built respecting all the structures fitted to preserve the environment and quarry working safety. Environment protection occurs by lower consumption and exhaust gas emission. Then, thanks to the presence of a hydraulic suction system, the issued dusts are immediately overturned and collected in suitable plastic bags.
Hydraulic drifters present acoustics emission values very low and this factor, allowed by technological innovations that constantly give improvements, has characterized our drifters, among the drilling equipment circulating up today with the lower noise emission. Finally the presence of a remote control panel allows to the operator in the quarry to work and check the machine at the proper distance guaranteeing an higher working safety, a minor exposition to the dangers, the accidents and the acoustic pollution.
