Cengar Universal Tools

Cengar Universal Tools

Cengar started business back in 1954 in Halifax, UK.  They patented the world's first twin piston air hacksaw in 1954, and then updated it in 1964.  Since then they have added new models and worked to improve the power, reliability and vibration levels of it's saws.  Recently Cengar updated it's production equipment to again improve quality and reduce lead times.

You will find Cenagr tools in oil rigs, refineries, fibreglass manufacturers, mines and pallet repair facilities all over the world.  They are used to cut steel plate, angle sections, I-beams, bolts, sections and pipes.  All of Cengars saws have very simple, reliable piston motors which use very little air.  No vanes, no bearings, no gears!  They are ATEX approved for T5, Zone 1 hazardous area use except for the Cengar JSM, which is ATEX certified to M2 for underground coal mine use.

Please beware, there are a number of copies of the Cengar CL50 and CL75. They are copies of the old version of these saws so they do not perform as well and they do not have ATEX approvals.  Spare parts are not compatible with modern Cengar saws, and it is an issue to find spares in Australia.

Assembly Technologies Pty Ltd are the Australian importers for Cengar saws.  We usually have all of the saws, blades and spares in stock.  Repair of the saws is very simple, any air tool repair shop should be able to repair them.  In case you have difficulty, we have a full work shop and are able to repair any Cengar saw.

High Volume Pallet Repairs

High Volume Pallet Repairs

A quick visit to Youtube shows a few dangerous, slow and really clumsy methods of repairing pallets.  Using long bars to pull apart the broken rungs and bashing in old nails brings a tear to our eyes!  

Using a special crow bar of some kind is labor intensive and danegrous if the operator is not careful.  Banging old nails flat is not a good idea if you are  going to replace the rungs because when you nail it back on the new nail can hit the old one and bounce straight back out.

We see many work shops using electric sabre saws to cut off nails.  It doesn't matter how much they spend on these saws, often they don't even last a year and they are dangerous because the cords can easily be damaged.

Cengar has developed two tools especially for pallet repair shops that are repairing pallets all day.  These tools reduce the operators' fatigue so that they can work longer without slowing down, as well as reducing the risk of injury.

Cengar Pallet Repair Saw PL905

The PL905 air hacksaw is a reliable workhorse that will easily last years of year round single shift work.  It features low vibration, a rugged housing and a simple pistion motor that just keeps on going as long as you have clean air and it is lubricated correctly.


Pallet Spreader

The PS2 pallet spreader effortlessly lifts the pallet rungs enough so that you can cut the nails.  A stopper stops the rung from springing out to hit someone in the face.





We also have pneumatic cutters that work exactly like hand operated side cutters, but they are powered by compressed air and easily will cut the toughest nails.

Stop losing money and putting your team at risk, there is a better way!  Please contact us for a demonstration. 

Cutting metals safely in hazardous areas

Cutting metals safely in hazardous areas

Whenever power tools are going to be used, the usual safety equipment is required such as goggles, gloves, safety shoes and ear protection the cutting of metal in hazardous areas or for long periods of time also requires additional safety considerations.

Risk of explosion:

When a tool is going to be used in a potentially explosive or hazardous area, it is not good enough to just use a "non sparking air tool".  When a risk assessment is done on any tool going into a hazardous area the basic question to ask is what is the maximum surface temperature of the tool, the blade and the material to be cut?  If explosive gases are present, what is the ignition temperature?  

Most operations will not have the facilities to rigorously test a tool's maximum surface temperature.  All of our air hacksaws are tested according to the European ATEX approvals.  This means that the tools have been independantly tested and have a coded approval marked on the tool showing the temperature class tha the tool is suitable for and what environment it is tested for (eg explosive dust or gas, industrial or mining areas).



Depending on how the saws are used, exposure to vibration levels has to be considered.  This is especially important when the saw will be used non-stop for more than half an hour.  During shut down periods in the oil and gas industries, as well as in production environments it is not uncommon for air hacksaws to be in constant use for 8 hours or more.  

Many tools have high vibration levels and according to European regulations cannot be used for more than an hour without a break.  Exceeding these vibration exposures can lead to vibration related injuries that take years to develop and are among the leading compensation claims in the EU.

Most low cost tools do not even state vibration levels, so a risk assessment should be carried out on the tool to determine whether using it for prolonged periods poses a risk to the operator.

All of our tools have their vibration levels clearly declared in their manuals and catalogues.  From these levels you can easily determine how long the tool can be used before the operator has to take a break.  If you would like more information on the vibration levels of our tools, please do not hesitate to contact us.


Cheap Copies:

Cheap copies of our saws are on the Australian market.  Besides being lower power, quality and life expectancy, they normally do not have ATEX approvals nor do they state their vibration levels.


All of our air hacksaws are ATEX approved and have very low vibration levels.
