Product DescriptionProduct DescriptionThe MWD series hydraulic excavators for coal mines draw upon the advantages of both domestic and international excavator frame structures and hydraulic systems, independently developed and manufactured. They feature reasonable dimensions, a compact structure, and convenient vertical lowering. They utilize an electric hydraulic system, offering advantages such as energy conservation, low noise, zero pollution, and high efficiency.These excavators are suitable for tunneling, rock loading, bottom cleaning, and excavation in frozen soil in coal, metal, and non-metallic mines, as well as vertical, inclined, and horizontal shafts. They perform a variety of functions, including excavation, bottom lowering, wall expansion, side excavation, crushing, rock breaking, scraping, cleaning the bottom of conveyors, loading vehicles, and leveling tunnels.The equipment features a compact structure and small dimensions. Its operating motion is controlled by a pilot valve, ensuring easy operation and smooth, impact-free operation. The working mechanism can not only adjust its luffing height but also swing 90° left and right in the vertical plane. The bucket can rotate 360° for excavation from below, from the rear, or from the side.Product DisplaySpecificationitemunitparameterWork qualitykg5800±5%6400±5%7800±5%8800±5%Shipping dimensions (L × W × H)mm3350×1300×25703350×1300×25703700×1650×26503700×1850×2650Engine parametersSpecificationsCumminsKL494DZLQFBKL494DZLQFBKL4107DZLQFBKL4107DZLQFBRated powerkW60608090Rated speedr/min2200220022002200Hydraulic system parametersRated pressureMPa25±0.225±0.225±0.225±0.2Main pump maximum flowL/min132±2132±2165±2198±2Traveling mechanism parametersTrack pitchmm135135154154Track shoe widthmm350350450450Track gaugemm95095012001400Track widthmm2146214623352335Track sections/lengthpcs/mm42/268542/268540/291440/2914Number of towing wheelspcsDrag chain plateDrag chain plate11Number of supporting wheelspcs6655Overall performance parametersBucket capacitym30.280.30.320.5Maximum digging forcekN≥40≥40≥50≥75Minimum turning radiusm≤2.5≤2.5≤2.8≤2.8Climbing ability°≥25≥25≥25≥25Ground pressure ratioMPa≤0.1≤0.1≤0.1≤0.1Walking speedkm/h(0-2.7)±0.2(0-2.7)±0.2(0-3.5)±0.2(0-3.5)±0.2Walking tractionkN≥42≥42≥60≥62Minimum ground clearancemm≥250≥250≥250≥250Rotation speedr/min7799Packing & DeliveryCompany ProfileShandong RELYSTONE Rail Equipment Manufacturing Co., Ltd. was established in March 2020 with a registered capital of 50 million yuan.The company mainly engages in the processing and sales of industrial and mining accessories.
