For global mine operators, the seasonal idleness of mining bulldozer is a tricky problem. Yukon Gold Mine in Canada once had 3 mining bulldozer idle for a long time due to the 6-month freezing period in winter, losing nearly $70,000 annually just from equipment depreciation and maintenance. However, after adopting the modification plan of Hengwang mining bulldozer, specially designed for foreign mining scenarios:
I. Winter ice-breaking modification: Enabling mining bulldozer to conquer frozen soil layers
Frozen soil layers in northern mines in winter often leave traditional equipment helpless, relying on explosive blasting, which is costly and inefficient. Hengwang HW22D mining bulldozer can be equipped with a customized ice-breaking shovel. Its TJM20 mechanical winch has a drum traction force of 350KN, and with a 20mm thick shovel, it can break 80㎡ of frozen soil per hour, replacing explosives at a cost of approximately $160 per hour. After introduction by Yukon Gold Mine, the operation rate of mining bulldozer in winter increased from 20% to 80%, creating an additional $160,000 in output value in 6 months.
II. Anti-trapping upgrade in rainy season: mining bulldozer operating efficiently in mud
In tropical rainy seasons, the trapping rate of ordinary bulldozers in muddy ground exceeds 30%. Hengwang HW17DE mining bulldozer solves this problem through two modifications: first, expanding the track plate width to 610mm, reducing ground pressure to 0.054kpa; second, increasing the number of track rollers to 7, improving chassis stability. After modification, the traffic efficiency of mining bulldozer in mud increased by 60%, enabling continuous operation without waiting for clear weather, reducing idle time in the rainy season by half.
III. Off-season rental utilization: Making mining bulldozer a profit-generating tool
When mines enter the off-season, the durability design of Hengwang mining bulldozer makes them popular in the rental market. The plated blade arm of HW13D has 50% improved wear resistance, and HW24DE is equipped with a Weichai WP13G271E471 engine (199kw power) that can adapt to various operating scenarios. According to international rental market conditions, the monthly rent of such mining bulldozer is about $2,100, and the income from a 3-month rental period can cover 15% of the annual depreciation cost, achieving "profit without operation".
Practice at Yukon Gold Mine shows that the annual utilization rate of modified Hengwang mining bulldozer increased from 50% to 90%, shortening the equipment investment payback period by 1.5 years.
