Construction Machines Names And Pictures

Construction blogger

Those who are in construction business would know very well that there are three major types of construction machines used for constructing buildings, roads, dams, bridges and the likes. These are earthwork machinery like excavators, dozers and loaders etc; roadwork machinery like road paver, chip spreaders, and compactor etc; and lifting machinery like cranes. Here in this article, you will come across the most popular and most widely used construction machines names and pictures with short descriptions about them.
Excavators, Dozer, Loaders Construction Machines
These three are perhaps the moct common construction machinery- excavators, dozers (bulldozer is the most famous name) and loaders.

Excavators- Excavators are the heavy construction and engineering machines that are used for digging and moving large objects on construction sites. Used heavily for making roads, buildings, highways, skyscrapers etc. excavators are indispensable for any project.
Dozer- A dozer is also a heavy equipment used to clear and grade land. These machines have continuous treads and a broad hydraulic blade in their front portion and are classified functionally on the basis of types of blades in a dozer. The two most popular dozers are the bulldozers and the scrape dozers.
Loader- Loaders, as the name suggests, are used on building sites to upload sand, debris, dirt and mud into other vehicles. Their end aim is to clear rubble and digging materials on the sites.
Chip Spreader, Road Paver, Compactor- Road Machines

While the excavators, dozers, and loaders can be seen on any construction site, there are certain specific machines that are only used while making roads.
Chip Spreader- This self-propelled road machine is used for pre-coated chipping surface treatments. It is also used in repairing works. Stone chipping gives quality and durability to roads and chip spreader is the main equipment used for this.
Paver- Also called road paving machine, it is used for laying pavement. Screed, tractor and lorry are its main component parts. It gets the material from lorry and places it in correct dimensions onto the prepared surface forming a mat like structure. This mat is then compacted by roadrollers.
Compactor- Te compactors reduce the size of waste materials through compaction and are found in different shapes, sizes and configuration. Plate compactors, vibratory compactors, sheeps foot compactors, steel rollers compactors with rubber tyres, etc. are some of the popular types of this construction machinery.
Cranes- Lifting Machines

Cranes are also an indispensable equipment for constructing purposes. These are huge tower like machines having provisions for lifting and lowering materials. They are operated by cab operator or with the help of infrared or radio signals. There are many types of lifting cranes such as tracked cranes, vehicle cranes or the truck mounted cranes and crawler cranes.

Top 6 Construction Site Hazards!

Construction blogger

Construction sites are considered the most potentially hazardous and accident-prone parts of any working environment. Excessive exposure to these construction site hazards exposes workers to injury and possible death. To prevent this, a company should know how to identify and be aware of all possible dangers that can be encountered during normal business operations. The Occupational Safety & Health Administration (OSHA) wants every employee to have sound knowledge of their susceptibility to harm or injury in the workplace.

Listed below are the top six construction site hazards identified by the Occupational Safety and Health Administration (OSHA):

1. Electrical- Electricity is one of the greatest hazards to people either at home or at work. Power line workers, electricians and electrical engineers work continuously with electricity and can face exposure to this hazard on a daily basis. At the construction site, the best way to prevent this kind of hazard is for the power line workers to be a safe working distance away from the power lines. Other precautionary measures includes guarding and insulating of the vehicle from which they might work. This would help prevent electrical hazards from injuring them while working.

2. Excavation and Trenching OSHA has recognized excavation and trenching as the most hazardous construction site operation. From the year 2000 to 2006, the United States Bureau of Labor and Statistics (USBLS) recorded 271 worker fatalities in trenching and cave-ins. These hazards are preventable yet injuries related to these hazards are still happening. Both employer and employee must follow safety standards and use protective equipment to minimize hazards while trenching and excavating.

3. Falls – Falling from scaffolding over six feet or a fixed ladder over twenty feet is the most dangerous and common construction site hazard. Falling from high places such as a ladder, scaffolding and roofs account for more than fifty percent of the accidents that happen at the workplace. The usual cause of this incident is slipping, tripping and using unstable ladders. There are thousands of reasons for fall hazards and to eliminate such risks, employers must have a fall protection program as part of any overall workplace safety and health program. Workers should be trained to identify and evaluate fall hazards and be fully aware of how to control exposure to such risks as well as know how to use fall protection equipment properly.

4. Stairways and Ladder – According to OSHAs construction safety and health standards, stairways and ladders are major sources of injuries and fatalities among construction workers. These recorded injuries are serious enough to put a worker out on sick leave. OSHA registered approximately 24,882 injuries and 36 fatalities yearly that are related to falling from stairways and ladders used at the construction site. To prevent such accidents and injuries, employers and employee must comply with OSHAs general rule for the safe use of ladders and stairways.

5. Scaffolding – Every year, approximately 60 workers die by falling from scaffolding; one out of five construction site falls are fatal. The most potential risk of scaffolding is due to moving scaffold components; scaffold failure related to damage to its components; loss of the load; being struck by suspended materials; electrical shock; and improper set-up. Construction workers who assemble and dismantle scaffolding and work platforms at construction sites face the risk of serious injuries due to falls. The scaffolding hazard is addressed by stated OSHA standards. They give specific requirements for the maximum load, when to use scaffolding, bracing and the use of guardrails.

6. Heavy Construction Equipment – Approximately 100 construction site workers die each year due to heavy construction equipment. The main causes of such accidents includes: ground workers struck when a vehicle is backing up or changing direction; equipment rollovers that injure the operator; mechanics run over when brakes are not properly set; and ground workers crushed by falling equipment from backhoes, buckets, and other moving construction vehicles. To prevent this kind of risk, workers should follow all construction safety guidelines necessary to eliminate the exposure to such injuries and accidents.

Safety risks on construction site are unavoidable; however, these can be prevented if workers are instructed on how to identify the hazards that might be present at the work-site. The employer must establish proper safety standards that meet the maximum requirements of the Occupational Safety and Health Administration. This will ensure that workers will have a safe working environment during normal operation.

This is not meant to be an all-inclusive list of construction site risks; however, these top six items are certainly important ones that all construction site employers should be aware of and continually working to eliminate them from happening.

The Uk Construction Trade’s Decline

Construction blogger

There is some dangerous news for those of you who step into your protective overalls for every day on the construction site every morning. Analysis by the Construction Merchandise Association (CPA) has shown that the construction business is going to continue declining for three a lot of years. Output is anticipated to fall by virtually 10 % this year and another four % the following year. This forecast is a lot of grimmer than previous reports and if this decline happens as predicted, it will be the most important decline in 30 years.

Chief executive of CPA Michael Ankers said, “The speed of decline is having a dramatic impact on many elements of the construction industry and is being driven by an unprecedented reduction in personal sector investment resulting from the credit crunch and economic downturn.”

The credit crunch affects all business sectors, significantly the motor and property industries, and the development industry is certainly no exception. The house building and repair sectors are the toughest hit with house starts expected to fall to their lowest level since the fifties and maintenance and residential improvements expected to fall by 15 % this year alone.

In addition to the present grim forecast, past construction output speaks volumes. Within the last 3 months of 2008, construction output within the UK came to ?19.3 billion which is ?1.5 billion down from the identical time period in 2007. But, the total output for 2008 was just about on par with the overall output for 2007.

However, construction output in some areas is seemingly to extend in the following years. Rail construction work ought to increase dramatically in the subsequent five years; the CPA report has predicted that it can increase by a hundred ninety%. Additionally to the current, public construction that is not housing-connected will go up by over 20 p.c in the following 2 years. Michael Ankers has asserted that the only sectors where construction output is forecast to extend are linked to public spending.

Spending on construction for education is expected to extend by nearly 30 p.c in the next 2 years, mainly because of the Building Colleges for the Future programme. The development trade is relying heavily on public spending throughout the recession. Luckily for those utilized within the trade, spending on public construction comes creates significantly more employment than different sectors of the trade and mainly British merchandise are used. This is often really the silver lining of the recession storm cloud for the trade and the well-developed British public sector is to thank for this.

Equipment Finance in India
The Indian mining and construction equipment finance market is yet to evolve. There are only 3 major players SREI Infrastructure finance, Cholamandalam DBS and Birla Global finance which cater to approximately 3% of the market as compared to 65% in developed countries. SREI also provides assistance to its customers throughout the lifecycle of the equipment and has initiated reverse auctioning of equipments in 2007.

Rental Equipment
The equipment rental business in India is currently pegged at around 7-8% of the total construction equipment industry which is nowhere close to what is seen in more developed markets with around 80% in Japan, 60-65% in USA and 35% in china . The Rental Equipment business in India is expected to grow to about 25% by 2010. The prominent organized players are SREIs Quippo, Sanghvi movers, Gremach Infrastructure equipments and Caterpillar .The average cost of hiring has gone up by approximately 30-40% over the last two years.

Nigeria Construction Equipment Industry Background & Historical Trends
Nigeria coal mining equipment cover a variety of machinery such as hydraulic excavators, wheel loaders, backhoe loaders, bull dozers, dump trucks, tippers, graders, pavers, asphalt drum / wet mix plants, breakers, vibratory compactors, cranes, fork lifts, dozers, off-highway dumpers (20T to 170T), drills, scrapers, motor graders, rope shovels etc. They perform a variety of functions like preparation of ground, excavation, haulage of material, dumping/laying in specified manner, material handling, road construction etc.

These equipment are required for both small-scale mining in Namibia. With a wide production capacity base, India is perhaps the only developing country, which is totally self-reliant in such highly sophisticated equipment. India has only a few, mainly medium and large companies in the organized sector who manufacture these.

Small scale gold mining equipment is machinery used to build and demolish bridges, buildings and other structures. These machines usually save labor, time and money. One of them can do more work in an hour than a hundred of workers using hand tools could do in a day. The chief kinds of building machines include earthmoving machineries hoisting, material handling machines and pumping machines. Other construction machinery used is for preparing the land and materials for construction. Demolishing machines are used to demolish structures and buildings.

The Indian construction equipment industry today faces stiff competition, great opportunities and challenges, but India has a total command over all these things as according to confederation of the Indian industry report, 2005 as for engineering and capital goods base. The Indian engineering manufacturing sector has been growing at the rate of about 5.9% in the nineties. India today produces a variety of machinery whose range is quiet wide and deep. Rapidly increasing construction sector has been the indication of good times for companies manufacturing construction equipments.
