Earthmoving Equipment is used in construction projects, you should be aware of different types of Earthmoving Equipment and the productivity rate for each Equipment
(how many cubic meters of soil can be moved or excavated in a certain amount of time or how fast materials can be transported).
Earthmoving Equipment (Earthmoving Machinery)
A bulldozer is a tractor unit with a blade attached to its front and it is an effective Earthmoving Machinery.
- The blade is used to push, shear, cut, and roll material ahead of the tractor. It is an ideal surface earthmover that performs best at a speed of about 3 mph.
- Each model of the bulldozer has an operating range for blade size and adjustment.
- Larger machines have greater operating ranges than smaller machines.
- A larger machine can pitch and tilt deeper than a smaller machine typically.
- For heavy civil work, bulldozer blade widths can range from 80 cm to 220 cm and operating weights can range from about 7 tons to over 120 tons.
- Maximum digging depth ranges from about 1.50 m to 2.50 m.
Bulldozer Productivity Rate m3 / hour
- Excavating only & haul in pile by dozer 75 HP (Horsepower), 15 meters haul, sand & gravel 43.5 m3 /hour.
- Excavating only & haul in pile by dozer 75 HP (Horsepower), 15 meters haul, common earth 38.4 m3/hour.
- Excavating only & haul in pile by dozer 75 HP (Horsepower), 15 meters haul, clay earth 27 m3 / hour.
- If the Dozer is 200 HP so multiply the productivity of the 75 HP by 2.3
- If the Dozer is 700 HP so multiply the productivity of the 75 HP by 13.44
2. FRONT-END LOADERS
Front-end loaders typically are tractors powered and operate on tires. They are typically articulated and very maneuverable, making them ideal for constricted areas.
- They are used primarily for material moving and re-handling. They are ideal for scooping and hauling materials in storage piles, where it is to be permanently placed, or loading them into dump trucks.
- Loaders are ideal for dumping soil back into the hole after the necessary below-grade work is done.
- Tracked loaders may be required for extreme surface conditions demanding greater traction or stability.
LOADER Productivity Rate m3 / hour
- Mix planting soil, including loam, manure, and peat, by skid steer loader at a productivity of 27.7 m3 / hour.
3. MOTOR GRADERS
This type of equipment has been around since the start of road building, though originally powered by a team of oxen, mules, or horses.
- The need for a smooth stable travel surface has always been an important part of a road system.
- Another name for a motor grade is ‘‘maintainer’’, this name is appropriate because this equipment is typically used to maintain grade and a smooth surface for rural non-paved gravel roads, or haul routes on construction sites.
- The blade is used to push dirt straight ahead or to the side at a desired level. The grader can be used for light surface excavation but is mainly used to move soil to create a level surface.
MOTOR GRADER Productivity Rate m3 / hour
COLD-LAID ASPHALT PAVEMENT
- The 100 mm coarse blade is mixed, spread & compacted at a productivity of 47.6 m3 / hour.
- The 100 mm coarse plant is mixed, spread & compacted at a productivity of 35.7 m3 / hour.
4. TRUCKS (Dumper Truck)
Trucks are an extremely important part of the earth-moving and material-moving process.
- They are basically a tractor and a trailer with sides. Like the rest of the equipment categories, there is a wide range of trucks based on hauling conditions and needs. Typically, trucks are sized by trailer volume. Obviously, the larger and heavier the load, the larger the tractor you need to pull the trailer.
- Trucks are typically used with excavators and loaders for excavation and soil haul-off or delivery. Compared to other earthmoving equipment, they can obtain high travel speeds. Rough terrain trucks have frames, suspension systems, and motors designed to traverse rough surfaces and radical travel grades.
- Trucks designed for hauling on the highway are designed for less rigorous conditions.
- Two basic considerations for choosing a truck trailer are the method of dumping and the class of material hauled.
- Trucks may dump from the rear (the most common), the bottom (belly dump), or the side depending on the type of material and work activity.
- Common rear dump trucks are typically not articulated, but larger rough terrain trucks are typically articulated for greater maneuverability.
An excavator is a heavy construction machine designed to dig, scoop, and move large amounts of soil, rock, or other materials.
- Excavators are highly versatile and commonly used in various construction projects, such as building construction, road development, mining, landscaping, and demolition.
- They are particularly useful for tasks like digging foundations, trenches, and holes, as well as loading and unloading materials.
EXCAVATOR productivity rate m3/hour
- Small Excavators (1 to 5 tons): 10 to 20 m3/hour.
- Medium Excavators (6 to 10 tons): 20 to 40 m3/hour.
- Large Excavators (11 to 50 tons): 40 to 100 m3/ hour.
- Heavy-Duty Excavators (Over 50 tons):100 m3/hour.
Keep in mind that these figures are just approximate and can vary based on factors such as the type of material being moved, the experience of the operator, the efficiency of the work site, and any potential equipment modifications or attachments used. Additionally, technological advancements and improvements in excavator design may lead to higher productivity rates over time.
