E-mailDrill loader BPR
TwitterMachine designed for loading of the rock mass destroyed by drilling and blasting, in mine cars, conveyor or other mine vehicles, during horizontal and inclined tunnels construction with raw cross-section from 8 m² in mines, hazardous with gas and dust, as well as for mechanization of drilling using 42 mm diameter drilling tool in faces where rock strength Ϭcompr ≤112 MPa when using rotational drill bit and Ϭcompr ≤ 224 MPa when using shock-rotational drill bit.
Two independent oil stations for separate control of drilling operations and destroyed rock load process.
Armored conveyor is reinforced with stripes of wear-resistant steel, increasing it’s lifetime by 2-3 times.
Loading plate gearbox with a 30 kW drive and one bevel gear.
Machinist workplace is mounted on the machine and equipped with electric and hydraulic control panels.
Possibility of inclined tunnels operation up to -18º using the holding device.
