Characteristics of several common construction machinery

The following is a detailed description of the characteristics of several common construction machinery:

1. Bulldozer
Features:

Flexible operation: The bulldozer is flexible, easy to operate, the required working face is small, the driving speed is fast, and it is easy to transfer.
Strong adaptability: can climb a gentle slope of about 30°, adapt to a variety of terrain and working environment.
Versatility: It is mostly used for leveling and cleaning the site, digging the foundation pit within 1.5m depth, backfilling the foundation pit, pipe ditch, etc.
Various walking modes: according to the walking mode is divided into crawler bulldozer and wheeled bulldozer. Crawler bulldozer has strong adhesion and good climbing performance. The wheeled bulldozer has high speed and good flexibility.
2. Scraper
Features:

Flexible operation: The scraper is composed of traction machinery and soil bucket, which can complete all earthmoving construction processes such as digging, transporting, leveling or filling.
Low requirements for roads: low requirements for driving roads, suitable for large area site leveling, excavation of large foundation pits and other projects.
Various walking modes: according to the walking mode, it is divided into tow scraper and self-propelled scraper. Towed scrapers are pulled by tractors, and the driving and working of self-propelled scrapers rely on their own power equipment.
3. Single bucket excavator
Features:

Variety: There are many kinds of single-bucket excavators, which can be divided into four kinds according to different working devices: shovel, backhoe, pull shovel and grab shovel.
Excavation methods vary:
Shovel excavator: forward upward, forced cutting soil, large digging force, high production efficiency, suitable for excavation of 1 to 3 types of soil above the stop surface.
Backhoe excavator: back down, forced cutting soil, suitable for excavation of 1 to 3 types of soil below the stop surface, as well as wet soil, moisture content and soil below the water table excavation.
Pull shovel excavator: back down, self-weight cutting soil, especially suitable for water content of large underwater soft soil and ordinary soil excavation.
Grab shovel excavator: straight up and straight down, self-weight cutting soil, mainly used for excavation soil relatively soft, construction surface relatively narrow foundation pit, trench, caisson and other projects.
4. Piling machinery
Features:

Strong specificity: pile machinery is mainly used in various pile foundation construction, such as drilling, piling, pile sinking and so on.
Small production batch: Due to the strong specificity of pile machinery, the production batch is relatively small.
Diverse structure: pile machinery is generally composed of two parts: pile hammer and pile frame, and pile frame can also be set on the excavator or crane to complete the pile driving task.
Various functions: including pile driver, pile press, vibration pile sinking machine, pile drilling machine, etc., each has different working principles and application scenarios.
5. Concrete machinery
Features:

High efficiency: such as concrete mixing and conveying machine, mixing pump truck, etc., set mixing, conveying, pumping and other functions in one, to achieve the full mechanized operation of concrete from production to pouring, greatly improving construction efficiency.
Convenience: The equipment is small and flexible, and can be easily shuttled around the site to provide convenient concrete supply services for various projects.
Safety: The design fully considers the safety factors, using a number of safety protection measures, such as hydraulic leg design, anti-blocking pipe technology, etc., to reduce the safety risk in the construction process.
6. Lifting machinery
Features:

Intermittent repetition: After the completion of one work cycle, then enter the next cycle.
Stable movement time is short: repeated starting, braking and forward, reverse and other alternating motion.
Suitable for short distance operation: mainly loading and unloading, poor handling function.
Poor versatility: the body is difficult to move, mostly fixed equipment.
Large working space required: Lifting from the upper part of the cargo.
In summary, all kinds of construction machinery and equipment have characteristics and advantages in design and function, and can meet different construction scenarios and needs.
