During this period, the whole vehicle withstood the test of the severe conditions such as the tight schedule of the retracement task, the heavy weight of the hydraulic support, and the long distance of the shearer (6.5 kilometers from the ground). It cumulative drawdown a total of 150 70-ton hydraulic supports and 160 40-ton stackers and a shaft work of the 116-ton shearer. It fully demonstrates the characteristics of reliable performance, low failure rate, and long cruising range of the vehicle, significantly prolongs the lead-acid battery replacement cycle, shortens the equipment maintenance time, and improves the efficiency of bracket withdrawal.</span></p><p><span style="font-size: 18px;">&nbsp;</span></p><p><span style="font-size: 18px;">The WC75E shovel pallet truck is equipped with a National III emission explosion-proof electronic injection diesel engine, adopts hydraulic mechanical transmission technology, designs a safe wet braking system, develops a large traction compact chain-type vehicle-mounted winch, and researchs a folding modular self-driving tank technology, integrates a full range of environment-aware active security systems, with the characteristics of large load capacity, low failure rate and high safety. </span></p><p><span style="font-size: 18px;">&nbsp;</span></p><p><span style="font-size: 18px;">Since March 2020, this model has undergone industrial tests on multiple working surfaces. During the period, it overcomes the severe working conditions of the heavy weight of the hydraulic support (maximum weight 79.5t), long equipment transportation distance (12km from the ground), and long-distance continuous ramp (3km long continuous 5° ramp). The cumulative installation and withdrawal of various hydraulic there are 386 supports, including 151 79.5t hydraulic supports; more than 20 times of handling 100-ton shearers, continuous miners and other heavy equipment, the total weight of the handling equipment reaches 25,000 tons, and the cumulative operating mileage exceeds 1,000 kilometers.</span></p><p><span style="font-size: 18px;">&nbsp;</span></p><p><span style="font-size: 18px;">&nbsp;</span></p><p><span style="font-size: 18px;">WX80J explosion-proof battery shovel plate carrier and WC75E explosion-proof diesel engine electronically controlled fuel injection system of CCTEG Taiyuan has laid a solid foundation for the demonstration and promotion of large mining height and super large mining height comprehensive mining moving equipment. Enterprises have provided strong support and guarantee for building green, efficient and safe mines.</span></p><p><br/></p>
