Units production construction equipment and machinery
Construction machines is a general term for a number of very different commercial vehicles used in construction, excavation or mining, such as: Wheel loader , Excavator - Backhoe loader , Roller , Concrete pump , Track-Type Tractors , Grader , etc. Many of these have further subgroups of vehicles configured for special applications. Therefore it is difficult to derive common buying recommendations. In general it can be said that construction machines are subject to excessive wear and tear, so that particular attention should be paid to: joints, axles, hydraulics, tyres, motor and transmission. The supply of spare parts is likewise an important buying criterion.VIDEO ON THE TOPIC: Shantui Construction Machinery, a Company Profile

Europe’s construction equipment manufacturers face major challenges
Heavy equipment or heavy machinery refers to heavy-duty vehicles , specially designed for executing construction tasks, most frequently ones involving earthwork operations or other large construction tasks. Heavy equipment usually comprises five equipment systems: implementation, traction , structure, power train , control and information. Heavy equipment has been used since at least the 1st century BCE when the ancient Roman engineer Vitruvius described a crane in De architectura when it was powered via human or animal labor.
Heavy equipment functions through the mechanical advantage of a simple machine , the ratio between input force applied and force exerted is multiplied, making tasks which could take hundreds of people and weeks of labor without heavy equipment far less intensive in nature.
Some equipment uses hydraulic drives as a primary source of motion. A portable engine ; a precursor to modern engineering vehicles. The use of heavy equipment has a long history; the ancient Roman engineer Vitruvius 1st century BCE gave descriptions of heavy equipment and cranes in ancient Rome in his treatise De architectura.
The pile driver was invented around The first tunnelling shield was patented by Marc Isambard Brunel in Until the 19th century and into the early 20th century heavy machines were drawn under human or animal power. With the advent of portable steam-powered engines the drawn machine precursors were reconfigured with the new engines, such as the combine harvester. The design of a core tractor evolved around the new steam power source into a new machine core traction engine , that can be configured as the steam tractor and the steamroller.
During the 20th century, internal-combustion engines became the major power source of heavy equipment. Kerosene and ethanol engines were used, but today diesel engines are dominant.
Mechanical transmission was in many cases replaced by hydraulic machinery. The early 20th century also saw new electric-powered machines such as the forklift. Caterpillar Inc. The first mass-produced heavy machine was the Fordson tractor in The first commercial continuous track vehicle was the Lombard Steam Log Hauler. The use of tracks became popular for tanks during World War I , and later for civilian machinery like the bulldozer. The largest engineering vehicles and mobile land machines are bucket-wheel excavators , built since the s.
This tool was the principal method by which material was either sidecast or elevated to load a conveyance, usually a wheelbarrow , or a cart or wagon drawn by a draft animal. In antiquity, an equivalent of the hand shovel or hoe and head basket—and masses of men—were used to move earth to build civil works. Builders have long used the inclined plane , levers, and pulleys to place solid building materials, but these labor-saving devices did not lend themselves to earthmoving, which required digging, raising, moving, and placing loose materials.
The two elements required for mechanized earthmoving, then as now, were an independent power source and off-road mobility, neither of which could be provided by the technology of that time. Container cranes were used from the s and onwards, and made containerization possible.
Nowadays such is the importance of this machinery, some transport companies have developed specific equipment to transport heavy construction equipment to and from sites. The Caterpillar D10 N bulldozer evolved from tracked-type tractors and is characterized by a steel blade attached to the front that is used to push other equipment and construction materials, such as, earth.
Normally the bucket is pulled toward the excavator to excavate material. The uncommon "thumb" attachment on this Komatsu PCLC enables 'grabbing' objects, for example, during demolition. Iron bar reinforced foundation piles are driven with a drilling machine, concrete pump, mixer-truck, and a specialized auger that allows pumping concrete through its axis while withdrawn.
A wheeled front loader tractor equipped with a large bucket elevated by hydraulic rams. Folded conveyor on a tracked grinder. The militarized Caterpillar D9 armored bulldozer allows for earthmoving projects in a combat environment. PiPz Dachs armoured engineering vehicle of the German Army Heavy equipment requires specialized tires for various construction applications. While many types of equipment have continuous tracks applicable to more severe service requirements, tires are used where greater speed or mobility is required.
An understanding of what equipment will be used for during the life of the tires is required for proper selection. Tire selection can have a significant impact on production and unit cost. There are three types of off-the-road tires, transport for earthmoving machines, work for slow moving earthmoving machines, and load and carry for transporting as well as digging.
Within these service categories are various tread types designed for use on hard-packed surface, soft surface and rock. Tires are a large expense on any construction project, careful consideration should be given to prevent excessive wear or damage.
A heavy equipment operator drives and operates heavy equipment used in engineering and construction projects. Much publication about heavy equipment operators focuses on improving safety for such workers. The field of occupational medicine researches and makes recommendations about safety for these and other workers in safety-sensitive positions. Due to the small profit margins on construction projects it is important to maintain accurate records concerning equipment utilization, repairs and maintenance.
The two main categories of equipment costs are ownership cost and operating cost. To classify as an ownership cost an expense must have been incurred regardless of if the equipment is used or not. These costs are as follows:. Depreciation can be calculated several ways, the simplest is the straight-line method. The annual depreciation is constant, reducing the equipment value annually.
For an expense to be classified as an operating cost, it must be incurred through use of the equipment. These costs are as follows: . The biggest distinction from a cost standpoint is if a repair is classified as a major repair or a minor repair. A major repair can change the depreciable equipment value due to an extension in service life , while a minor repair is normal maintenance. How a firm chooses to cost major and minor repairs vary from firm to firm depending on the costing strategies being used.
Some firms will charge only major repairs to the equipment while minor repairs are costed to a project. Another common costing strategy is to cost all repairs to the equipment and only frequently replaced wear items are excluded from the equipment cost. Many firms keep their costing structure closely guarded [ citation needed ] as it can impact the bidding strategies of their competition.
In a company with multiple semi-independent divisions, the equipment department often wants to classify all repairs as "minor" and charge the work to a job - therefore improving their 'profit' from the equipment. Die-cast metal promotional scale models of heavy equipment are often produced for each vehicle to give to prospective customers.

Demand diversity in the construction equipment sector
For many industrial manufacturers, what was once a clear path to success is now fraught with uncertainty. Making equipment for a wide array of industrial activities — such as big construction projects, large industrial facilities, oil and gas fields, and refineries — has for years been difficult to navigate, but major companies often used their size to sidestep obstacles. The strength of having multiple product lines covering the full gamut of industrial operations frequently allowed industrial manufacturers to eke out profits from some segment of their customer base even as slowdowns imperiled other sectors. But juggling business in this way is no longer a viable strategy, particularly if a company relies on traditional machinery for its revenue streams, as many industrial manufacturers do.

The hourly cost of the tractor with operator is called the machine rate. In cases where the machine and the elements of production are not rented, a calculation of the owning and operating costs is necessary to derive the machine rate. The objective in developing a machine rate should be to arrive at a figure that, as nearly as possible, represents the cost of the work done under the operating conditions encountered and the accounting system in use. Most manufacturers of machinery supply data for the cost of owning and operating their equipment that will serve as the basis of machine rates.
