Hydraulic Repairs after Natural Disaster

Hydraulic repairs in South Africa need to be carried out effectively and efficiently – and even though we are not as susceptible to natural disaster in this country that can cause serious damage to hydraulic dams and other industries driven by hydraulics, it is important to have efficient hydraulic repair centres in place to carry out emergency repairs through any and all eventualities. Mobile hydraulic repair units make a massive difference when an emergency situation occurs.

When nature strikes with all its might people are usually completely powerless against it. Not too long ago a tornado in the Free State claimed five lives and wreaked untold havoc – other natural phenomena include earthquakes, floods and active volcanoes which often make headline news.

Of particular note are the recent tsunamis that caused untold damage to places such as Thailand and Japan. Here are some natural phenomena that can and will cause damage to buildings, dams and other man-made structures.

Tornadoes:

  • A tornado can cause enormous destruction and consists of rotating columns of air which comes into contact with the ground and also with cumulonimbus clouds or thunder clouds.
  • Tornadoes vary in shape and size and also in intensity but are usually in the shape of a funnel and most have wind speeds of 180km/h but in exceptional instances they can reach speeds in excess of 480km/h.
  • Tornadoes suck up objects in its path and deposit them elsewhere.
  • Experts do believe that tornadoes in South Africa occur more regularly than we realise – they are more than likely not reported because rural areas are not densely populated.
  • In October 2011 two tornadoes struck Duduza near Johannesburg and Ficksburg some 250 kms south – two people died and 200 were injured and almost 2000 people were left without a roof over their heads.
  • In 1948 in Roodepoort a tornado destroyed 500 houses, killing four people.

Industry is reliant on hydraulics across the board where these are used in a plethora of applications – if you do fall victim to Mother Nature, it is good to know that mobile hydraulic repairs in South Africa are equipped to deal with these and numerous other disasters.

On The Shelving of Famous Libraries

Did you know that in the ancient Library of Alexandria in Egypt, information was recorded on hundreds of scrolls of papyrus and stored rolled up on hundreds of rows of shelving? Naturally the libraries of old looked a lot different to what they do today.

For many readers libraries are places where silence is of paramount importance where scholars gather information and take refuge to study – but modern libraries today are far removed from the libraries of old and provide a broad range of services and valuable information to the public.

Most cities and towns have their own libraries with a vast range of books to satisfy the needs and the tastes of readers in a community with each one being made up of different sections and numerous shelving that house books ranging from fiction and non-fiction have a reference section and a section for computer users. Libraries also have archives which house old records and newspapers dating back for decades.

If you are a history buff why not pay a visit to the newly-restored and handsome Johannesburg City Library in the heart of the CBD of Johannesburg? You would be amazed at how excellent this building is.

Books are classified and arranged on the shelves according to the Dewey Decimal Classification system, otherwise known as the DDC system, which allows readers to find a specific book easily or to find the books of a certain author. American Melvin Dewey developed this system in 1876 which is still in use all over the world in libraries today to classify and arrange books on the shelves of libraries.

Of particular interest is that more than 200 000 libraries make use of this system in more than 135 countries.

Today libraries are established through the world but this was not always the case – before libraries could house books on shelving, a system of writing had to be developed to record people’s thoughts and ideas. In a nutshell libraries store records of human achievements, knowledge and culture.

Where would we be in the world of today if we did not have libraries filled with shelving overflowing with books? It is indeed a privileged society that we enjoy where we have books to read, libraries filled with shelving housing these books and above all, the ability to be able to read these books brimming with knowledge that are housed on the shelves in libraries.

A New Forklift Range Will Assist With Storage Ideas

A new forklift range is specifically designed so that you will now be able to increase the vision that you have for your storage solutions and give you storage options and storage ideas that you never knew you had. Moving offices, factories, warehouses or any other premises is a momentous task, and the cost involved to make this happen is astronomical, plus there will be downtime that few businesses can afford; therefore it might be better to look for solutions to increase storage for the space you already own.

Materials handling specialists have been appointed to deal with very narrow aisles with articulated forklifts which are manufactured by international handling solutions providers – these articulated forklifts are specifically designed to increase storage capacity, reduce costs and boost productivity.

By narrowing working aisle widths to just 2m, this enables vastly increased pallet density and the potential to achieve an increase in storage capacity to up to over 50% over traditional forklifts and 30% over reach trucks which usually requires a much bigger working area. In addition they are designed to work both inside as well as outside.

The new narrow-isle forklifts showcase special features such as solid pneumatic tyres for loading and offloading goods both inside and outside warehouses.

These new forklifts will save money all-round because they are perfect for increasing storage space and will be able to replace a combination of trucks for outside tasks and an electric reach or guided truck for placing pallets outside.

If you are out of good storage ideas and desperately need more storage space – increase your storage capacity simply by making your isles narrower, replace your forklifts to smaller ones that will work narrower spaces, and you will be astonished at how much more storage space you will gain.

Proudly South African

SA-designed impact crusher has been unveiled by Pilot Crushtec. Crushing and screening equipment producer Pilot Crushtec has unveiled its indigenous South African designed TwisterTrac VS300 300 t/h impact crusher – something they are truly proud of.

This is a second-generation tracked vertical shaft impactor which is not only user-friendly but is also really quite easy to maintain. The impactor has been specifically designed to apply to high volume tertiary and quaternary crushing applications which results in sand and fines with the augmentation of quality.

This crusher accommodates four varying engine models, meeting current market requirements and needs as well as the increasingly strict engine emission regulations which are enforced in both Europe and the USA.

In order to accommodate increased power output the sizes of the diesel and hydraulic tanks have been enlarged and tailored accordingly.

A noteworthy feature of the TwisterTrac is its CANbus electronic power structure which has instantaneous filter monitoring and the most up-to-date human/machine interaction technology. While this machine boasts the very latest programmable logic controller technology, the control systems come with excellent graphic illustrations to support the operator of the compactor.

This crushing and screening compactor proves how innovative and progressive SA is when it comes to designing and manufacturing mining equipment. Towards the end of 2011 Pilot Crushtec’s latest shaft impact crusher was ready to start field tests and prototyping and delivery of the compactor went ahead in April 2012.

Safer Shaft Sinking in South Africa

Shaft Sinking

A combination of technical techniques is a first for shaft sinking at SA manganese mines. Soft ground digging, drilling, blasting and raise boring are being combined for the very first time to sink new shafts at manganese mines in South Africa.

This ground-breaking method of shaft sinking will increase safety and will also improve productivity of the shaft sinking process.

This marriage of technologies has significant potential and mining companies have the need to look at all possibilities of boring shafts in the future rather than using drill and blast methods to sink mine shafts.

The South African mining industry has been using specific safety methodologies for a long time. These need to be replaced by new methods and state-of-the-art systems that are yet to be embraced in this country which have been used quite successfully in other mining regions in the world.

Resistance to change remains a challenge but change should be welcomed because there are numerous technologies that are well proven and found to be successful in other regions such as Australia, Canada and Australia.

It is indeed time for the mining fraternity in South Africa to rethink safety, as too many lives are unnecessarily lost underground.

REFRIGERATION COMPRESSORS

The heart of every mechanical refrigeration system is its refrigeration compressor. It is a pump that keeps the system’s essential fluids circulating and, if we want the system to keep operating for many years, you ought to treat this component with care

Refrigeration compressors are used for large-scale facilities and equipment. They compress low-pressure, low-volume gas into high-pressure and high-temperature gas. They also remove vapor from the evaporator. Most of these compressors are large, mechanical units that run industrial cooling systems or heating, ventilation, and air conditioning systems.

The 3 main categories of refrigeration compressors are screw, scroll and piston. Refrigerant vapor is passed through screw spindles which compress the gas and while most screw compressors have two spindles, there are products with three or more spindles as well. Scroll compressors are the most common type and they have a relatively low rate of leakage but give one a high efficiency. Piston compressors are especially designed for industrial and commercial purposes. This type compresses gases to high pressures and is designed for continuous operation. There are however other types of refrigeration compressors available.

To select the right product – you need to do an analysis of refrigerant options and cooling specifications. The 4 cooling specifications to consider are capacity, input power, condensing and evaporative temperatures. Capacity measures the ability of a refrigerant compressor to remove heat from the refrigerant gas. A typical refrigeration compressor can run at many different values with the corresponding changes in their cooling capacity.

Refrigeration compressors are designed to pump gas, not liquid.  Some serious airflow problems and TX-valve problems can cause liquid refrigerant to enter the compressor and because liquid refrigerant is not compressible and it tries to pump too much liquid too fast – the pistons, valves, and connecting rods can bend or break.


Compressors Play an Integral Part in the Refrigeration and Air-Conditioner Industry

Compressors, condensing units, refrigeration and air-conditioner units; they are all-important for the smooth running of air-conditioning and refrigeration in all aspects of industry.

Whether you have a business that transports fresh produce from point A to point B, or whether you run an office park and require cooling or cooling systems for shopping centers; perhaps you might require cooling systems to cool industrial machines. No matter what your needs are, you should take into account that condensing units play a vital role and work hand in glove with compressors.

Macs Auto supplies a full range of condensing units that are suitable to be used in all makes of motor cars, too. Imagine driving in the heat, especially that of Africa, without the efficient running of an air-conditioner unit? This is made possible only because condensing units together with compressors play such an integral part in the smooth running of these machines. Condensing units are used to disperse and dissipate the heat inside the compressor. Ambient air then flows through the condensing unit while absorbing the heat from the warmer condenser.

Compressor failure is usually a direct result of the failure of the condensing unit.

Air conditioning units are something we simply take for granted, but there are certain mechanical elements that are required in order for your unit to run smoothly at all times; one of these is the all-important compressor, which is one of the vital components that will ensure that your air conditioner is functioning optimally at all times.

Advantages of Macsauto Compressors

  • Macsauto imports all its own compressors and supplies workshops with the essential tools that are necessary to repair all air conditioners.
  • Compressors fall into the extensive and excellent category of tools that are imported by Macsauto.
  • There is outstanding training available to learn how to correctly use of compressors and other equipment carried out by Macsauto, which is highly recommended.

Used machine tools – Part 2

USED MACHINE TOOLS – Part 2

A machine tool is typically powered by electrically, hydraulically, or via line shaft and is used to make manufactured components by cutting or grinding on metal.  There are approximately 600 machine tool brands and 7500 new models to choose from.  However, the global economy crisis put pay to using new products and manufacturers were forced to look at used machine tools instead.

Falling into the category of capital goods as it does, machine tools have been greatly affected by the new credit system.  The sale of machine tools was negatively affected by the freezing of capital expenditure and because of its dependence upon the end-users in the manufacturing and automobile industries.

As a result of this South Africa’s international competitiveness in manufacturing has started to materialise due to the utilisation of new technologies and there are now many companies that specialize in the selling of us machine tools and new fabrication and engineering of machines.  They supply a range of used machine tools, accessories, tooling, consumables and services to the metal working industry and the engineering industry at large. They usually employ full time technicians that are factory trained to repair, install and commission these different machines and provide expert advice for manufacturing processes, complete turnkey projects, installations and commissioning and training on the equipment sold. 

With regard to the used machine tool industry, some companies are even offering in-house training in the use of this machinery – particularly the programming of CNC machines.
