- Tadano GR-1000XL-4: Compact yet powerful for rough terrains.
- Manitowoc MLC650: A lattice boom crawler crane with superior lifting capacity.
5. Concrete Mixers
Function: These machines mix cement, aggregates, and water to create concrete.
Types:
- Drum Mixers: The rotating drum mixes the concrete.
- Continuous Mixers: Produce concrete without interruption.
- Mobile Mixers: Allow on-site mixing for immediate use.
Popular Models:
- Cemen Tech C60: A mobile concrete mixer with precise calibration.
- Schwing Stetter M1: Efficient for batching large amounts of concrete.
- Volvo FMX: A truck-mounted mixer with excellent durability.
6. Road Construction Machines
Function: These machines are critical for building and maintaining roads.
Key Machines:
- Pavers: Lay asphalt for roads and parking lots.
- Road Rollers: Compact and smooth the asphalt or soil.
- Cold Planers: Remove old asphalt layers.
Popular Models:
- Dynapac SD2500: A high-performance asphalt paver.
- Bomag BW 213: A road roller with advanced compaction technology.
- Wirtgen W 220: A cold planer ideal for large-scale milling tasks.
7. Graders
Function: Graders level surfaces and create smooth, flat foundations for roads and buildings.
Popular Models:
- Caterpillar 140 GC: Known for its low operating costs.
- John Deere 772G: Offers precise grading with high horsepower.
- Komatsu GD655-6: Equipped with a powerful engine and ergonomic controls.
7. Trenchers
A trencher is a piece of construction equipment used to dig trenches, especially for laying pipes or electrical cables, for installing drainage, or in preparation for trench warfare.
Trenchers may range in size from walk-behind models, to attachments for a skid loader or tractor, to very heavy tracked heavy equipment.
Trenchers come in different sizes and may use different digging implements, depending on the required width and depth of the trench and the hardness of the surface to be cut.
A wheel trencher or rockwheel is composed of a toothed metal wheel. It is cheaper to operate and maintain than chain-type trenchers. It can work in hard or soft soils, either homogeneous (compact rocks, silts, sands) or heterogeneous (split or broken rock, alluvia, moraines). This is particularly true because a cutting wheel works by clearing the soil as a bucket-wheel does, rather than like a rasp (chain trencher).
8. Wheel tractor-scraper
In civil engineering, a wheel tractor-scraper is a piece of heavy equipment used for earthmoving.
The rear part of the scraper has a vertically moveable hopper with a sharp horizontal front edge which can be raised or lowered. The front edge cuts into the soil, like a carpenter’s plane cutting wood, and fills the hopper. When the hopper is full it is raised, closed, and the scraper can transport its load to the fill area where it is dumped. With a type called an ‘elevating scraper’ a conveyor belt moves material from the cutting edge into the hopper.
9. Dump Trucks
Function: Transport heavy loads of materials such as dirt, sand, and gravel.
Popular Models:
- Volvo A40G: Known for its efficiency in heavy material hauling.
- Caterpillar 797F: A mining dump truck with enormous capacity.
- Komatsu HD785-7: Offers durability and reliability in harsh conditions.
