Bulldozer Specifications
The figures below describe typical industry specifications for this class of equipment rather than a single fixed model. Use them to scope a requirement, then confirm exact figures against the supplied unit before purchase.
| Specification | Typical value |
|---|---|
| Common classes | D5–D8 equivalent, 100–300 kW |
| Operating weight | 15–40 t for small to mid mine duty |
| Blade types | S (straight), SU (semi-U), U (U-blade), PAT (6-way) |
| Blade capacity | 3–12 m³ depending on class and type |
| Ripper | Single or multi-shank; essential in laterite and compacted fill |
| Tracks | Standard, LGP (low ground pressure) or rock shoes |
| Fuel consumption | 18–40 L/h |
| Drive | Torque converter or hydrostatic |
| Cab | ROPS/FOPS, air-conditioned |
What a Bulldozer Is Used For
- Haul-road construction and maintenance
- Overburden stripping
- Stockpile pushing and reclaim
- Pad, dump and tailings-wall construction
- Ripping compacted laterite and road base
Maintenance Schedule
Most premature failures in this equipment class trace back to a missed routine check rather than a design fault. The intervals below are a practical starting schedule; adjust them to your duty cycle and the manufacturer manual.
| Interval | Task |
|---|---|
| Every shift | Track tension, blade cutting-edge wear, ripper tip and hydraulic leaks. |
| Daily | Grease blade and ripper pins; clean radiator; check final-drive oil levels. |
| 250 h | Engine oil and filters; inspect undercarriage rollers and idlers. |
| 500 h | Fuel and hydraulic filters; track-shoe bolt torque. |
| Undercarriage life | Turn or replace pins, bushes and shoes as a set; undercarriage is the dominant wear cost. |
Frequently Asked Questions
Do I need a dozer if I already have an excavator?
Yes, if you have haul roads. An excavator cannot efficiently spread, compact-prep or maintain a running surface. Trucks on a badly built road burn fuel, destroy tyres and lose cycle time — usually more cost than the dozer. On a one-machine artisanal pit you can postpone it; on anything with a haul you cannot.
Straight blade or U-blade?
Straight or SU for road building and precise grading. U-blade for moving large volumes of loose material on dumps and stockpiles. PAT six-way blades suit construction finishing. Mining road work is SU more often than not.
What destroys dozer undercarriage?
Packing of fines in the track, running always in one direction on a slope, and worn sprockets left in service. Clean the tracks, reverse the working direction through the shift, and replace sprockets with the chain, not after.
