In African desert mining, Bulldozers for desert mining often face challenges such as getting stuck in soft sand layers, sand burial on slopes, and high-temperature heat dissipation. Mastering the following practical skills can significantly improve operational efficiency and reduce the risk of failures:
I. Sand ore pushing: Layered compaction to avoid sinking
Problem: Soft sand layers easily cause bulldozers to sink, resulting in low ore pushing efficiency.
Solutions:
Edge compaction method: First use the blade to level the edge of the sand, gradually compacting toward the center to form a stable base;
Low-speed, high-torque propulsion: Utilize the low-speed torque advantage of the Weichai WP13 National IV engine (rated power 266kW) to avoid sand blowing from high-speed driving;
Real-time adjustment of track tension of the Bulldozer for desert mining: Tighten the tracks during sand operations (refer to the 560mm extra-wide track design of HW34D) to reduce the probability of slipping.
II. Gobi slope finishing: 45° layered quantity control skills
Problem: Gobi slopes are easily affected by wind, causing sand particles to flow back and leading to rework.
Solutions:
Angle control: Adjust the blade to a 45° angle to use gravity to assist in unloading;
Layered leveling: Single-layer bulldozing thickness ≤15cm, combined with the three-stage blade adjustment system of HW26DE Bulldozer for desert mining to ensure slope flatness;
Anti-backflow design: Set up temporary sand barriers (such as leveled sand piles) on both sides of the slope to block wind interference.
III. Getting unstuck: Low-torque slow retreat for safety
Problem: Slamming on the accelerator after getting stuck in sand can damage the transmission system.
Solutions:
Reverse gear slow retreat: Gently step on the accelerator to reverse, using the reverse thrust of the tracks to gradually get out of trouble;
Clean sand in tracks: Use the blade to remove sand between the tracks and load-bearing wheel to restore grip;
Emergency traction preparation: Install a tow hook on the Bulldozer for desert mining in advance (standard on HW32D) for external rescue.
Common user questions and prevention plans
Q: What if the blade heats up too quickly?
A: Regularly clean the radiator of the Bulldozer for desert mining (HW17DE is equipped with a 16kW high-power heat dissipation system), and avoid long-term high-load operation during work.
Q: How to handle sand entering the transmission case?
A: Use special grease (high-temperature resistant type) and install a transmission case dust cover (optional accessory).
