In copper mines in the Democratic Republic of the Congo, hard rock crushing is like "chewing bones" — manual work with pneumatic picks on granite yields only 0.3 tons per day; traditional bulldozers suffer from blade cracks, hydraulic system oil leaks, with an equipment failure rate as high as 35%; dust fills the air, clogging the engine compartment's heat dissipation ports, leading to scrapping in just six months. These pain points are all solved by Hengwang's flagship bulldozer for sale model HW32D!
Pain Point 1: Low hard rock crushing efficiency and high equipment loss
Mining hard rocks (Mohs hardness 6-7) are "tough nuts". Ordinary bulldozer blades, made of soft material, crack after hitting 20 rocks; insufficient hydraulic system pressure makes pushing boulders feel like "pushing cotton". Hengwang HW32D, this bulldozer for sale:
Equipped with a 4868kg reinforced semi-U blade (30% heavier than conventional blades) with tungsten steel overlay on the edge, achieving a granite crushing efficiency of 15 tons/hour (50 times that of manual work);
500ft-lb high torque output (Cummins 257kW engine + 16MPa hydraulic system) with a traction force of 350KN, easily pushing 5-ton boulders, and the blade remains crack-free for 10 years.
Pain Point 2: High-dust environment leads to "short-lived" equipment
Mining dust concentration often exceeds 800μg/m³. Ordinary engine compartments lack sealing, clogging heat dissipation ports; hydraulic oil contaminated with dust causes valve core jamming, requiring major overhauls in six months. Hengwang bulldozer for sale HW32D:
IP67 dustproof engine compartment: Multi-layer labyrinth sealing, enabling continuous operation for 500 hours in PM10 environments without dust accumulation;
Hydraulic oil triple filtration (10μm precision filter), with oil cleanliness at NAS 8 level, ensuring valve cores remain unjammed for 5000 hours;
Automatic dust-discharging tracks: Track links with 228.6mm pitch and chip grooves, achieving a 90% removal rate of gravel and dust, extending equipment life by 3 times.
Pain Point 3: High demand for long service life and high maintenance costs
Mining operations are intensive, with annual equipment failure rates exceeding 30% and maintenance costs accounting for 25%. Hengwang bulldozer for sale HW32:
Dual-pump independent oil supply system: No leakage after 2000 hours of continuous operation, extending hydraulic system life by 3 times;
Modular design: Blades, cylinders and other components can be quickly replaced in 10 minutes, reducing annual maintenance costs by 40%.
Field test at Kasama mining area in Zambia:
After the HW32D bulldozer for sale was put into use, hard rock crushing efficiency increased from 0.5 tons/hour to 15 tons/hour (30 times improvement), equipment failure rate dropped from 35% to 5%, saving $120,000 in annual maintenance costs. Mine owner Mulengu said: "This bulldozer for sale turned my mining area from a ‘loss-maker’ into a ‘money-printing machine’!"
