Building construction is technically defined as the industry involved in the assembly and erection of structures, primarily those used to provide shelter. It is an intricate process which requires high levels of collaboration to be successful.

The present state of building construction is complex. There is a wide range of building products and systems which are aimed primarily at groups of building types and markets. The design process for buildings is highly organized and draws upon research establishments that study material properties and performance, code officials who adopt and enforce safety standards, and design professionals who determine user needs and design a building to meet those needs.

Considering construction processes, they require highly organized assembly lines and integrated network follow-throughs; it includes the manufacturers of building products and systems, the craftsmen who assemble them on the building site, the contractors who employ and coordinate the work of the craftsmen, and consultants who specialize in such aspects as construction management, quality control, and insurance.

Challenges in large-scale building arise when the need for workable space for both shelter and commercial use came about. This has resulted to manual labor to seem inadequate in getting the job done. It is in this reason that heavy equipment was invented.

While heavy equipment is utilized in a wide array of applications and fields, this group of jacked up automotive is mostly applied in the field of building construction. Some of these machines are familiar to people as they are frequently visible in the field, yet most people are unaware of specific functions, even the names of these equipment.

For those who want to get in the construction industry, here is a list of important heavy equipment necessary in practically every major construction project out there.

Bulldozers

Construction industry requires constant movement of material in order to make the site accessible and to allow the initiation of the processes and steps required in building construction. Simply put, a disorganized construction field where workers are required to do their jobs often make the construction process inefficient. This is why it is essential to take away obstacles such as chunks of big rocks and loose soil in the field faster and more efficiently. As such, bulldozers come in as basically a tractor which helps push these large blockades away.

Primarily, it is made up of metal plate called a blade, which is used to drive a significant amount of material in a specific place, and the ripper, which is the extended device at the bulldozer rear that crushes or rips materials.

There are various types and manufacturers of bulldozers, yet the commonly relied on type in the mining industry is the Caterpillar D11. This monster is powered by a 770 horsepower (570 kW), 2,105 cu in (34.49 L) 3508 V-8 Diesel engine and can move large quantities of dirt rock and aggregate.

Its close competition, the Komatsu D475A is the second largest in the Komatsu line. The 740 horsepower (550 kW) D475A-1, introduced in 1986 as a replacement for the 650 horsepower (480 kW) D455A, can perform a significant amount of pushing like the D11. However, the latter edges it with its elevated drive sprocket, or “High Drive” system, which results in a triangular, rather than oval, shaped track.

Considering the price range of these vehicular tools, listings over the web prices D11’s go for $500,000-$1.4 Million. On the other hand, Komatsu D475A ranges from $300,000- $1 Million. These numbers are relatively fair for its wide array of purposes.

Concrete Mixers

Special concrete transport trucks or in-transit mixers are made to transport and mix concrete up to the construction site. They can be charged with dry material and water, with the mixing occurring during transport. With this process, the material has already been mixing. The concrete mixing transport truck maintains the material’s liquid state through agitation, or turning of the drum, until delivery.

The interior of the drum on a concrete mixing truck is fitted with a spiral blade. In one rotational direction, the concrete is pushed deeper into the drum. This is the direction the drum is rotated while the concrete is being transported to the building site. This is known as “charging” the mixer. When the drum rotates in the other direction, the Archimedes’ screw-type arrangement “discharges”, or forces the concrete out of the drum. From there it may go onto chutes to guide the viscous concrete directly to the job site.

 

Aligned with the aforementioned movement of materials, concrete-mixing trucks are used to deliver construction raw materials more efficiently since the mixing is done while on the road. Since time is a major factor in any building construction plan, in-transit mixers make it possible to deliver important materials, primarily cement, for the workers to apply. Top of the line concrete-mixing trucks normally range to $150,000 and up, dependent on mixing capacity, engine and chassis model.

Excavators

Excavators are heavy equipment consisting of a boom, stick, bucket and cab on a rotating platform also known as the house. This house sits just above an undercarriage with tracks. On simpler terms, excavators are called ‘diggers’.

The heavy equipment can be used in a wide array of applications such as digging of trenches, holes and foundations, material handling, brush cutting with hydraulic attachments, forestry work, demolition, general landscaping, river dredging and, driving piles in conjunction with a pile driver. This machine works because of the presence of hydraulic fluid, with hydraulic cylinders and hydraulic motors.

The Komatsu line boasts of their heavy duty and reliable excavators such as the Komatsu PC 228 USLC-3 powered by 6 cylinder turbocharged 155HP, 116KW engine. The PC 200 LC-8 hydraulic excavator, on the other han, boasts of low fuel consumption powered by 155HP, 116 KW low emission engine.

Then again, if acquiring theses machines comes as a challenge, excavator rentals may be an alternative. Equipment rental service is all over the web and is really inexpensive, making the access of these high-powered machineries much more convenient. With rental fees range from $8,500 to $9,300 per month, it is indeed a highly viable option.

Cranes

A crane is a machine which is generally equipped with a hoist, wire ropes or chains, and sheaves, which can be utilized in moving materials to different parts of the construction site. With its high performing mechanism, cranes are capable of lifting, lowering and moving of heavy materials with the use of pulleys and cables.

Considering their function, these machines are valuable assets for the construction industry because they make things a lot easier and more convenient in any type of construction. Nowadays, there is little to no worry when building at any place, even in the middle of river or within busy locations with adjacent skyscrapers.


It is important to take note that cranes serve in the construction as temporary structures. In fact, they are mounted on vehicles for the purpose of easy maneuvering. Generally, most of the cranes are mounted to trucks except for much heavier ones, like rough terrain crane – a special type of vehicle mounted crane that is used when a normal vehicle mounted crane is not suitable for off-road work or rough terrain places. In this case, the vehicle mount’s wheels are made with rubber as to allow faster movement. Also, outriggers are provided to the base of the vehicle to induce a high level of stability to the crane while working.
