Rough Rides – Heavy Equipment Scrapers



Heavy Equipment Scrapers are extremely rough rides.   Scrapers will expose the operator in a scraper seat to excessive levels of whole body vibration that may lead to injury or illness.  This also takes a toll on the scraper seat and often times requires various parts to be replaced over the years.


Scraper operators are exposed to higher than recommended levels of vibration and therefore a properly operating scraper seat is of outmost importance.  Scraper seats tend to be one of the more expensive heavy equipment seat to replace and also get parts for.   Seats that are built specifically for a heavy equipment scraper should be extremely robust.   Resist the urge to cut cost by putting a seat that is not designed to be a scraper seat as cost in the long run will be exceeded due to the shortened life of an inferior seat.  The scraper operator ride comfort will suffer as well with a seat not designed to handle the excessive vibration on a normal scraper run.

If opting for a scraper seat other then OEM, the size of the shock is an easy way to tell if you are purchasing a seat built for the task.  Verify the shock in the seat is at least 1.5″ in diameter or larger as a smaller shock will fail much more rapidly leading to other issues in the seat and ride.  In addition the components in a scraper seat will be much more heavy duty.

Scraper seats are sometimes offset or swivel and come with in a variety of heights depending on the model Scraper. Be sure to get the right seat for your scraper by contacting an application specialist at  e sometimes offset or swivel and come with in a variety of heights depending on the model Scraper.

Caterpillar scraper seats as well as Terex scraper seats and John Deere scraper seats are availble that are direct bolt in replacements.   Replacement parts for these scraper seats from are also available.

Things to Consider when Looking for a New Dozer Seat or Loader Seat

dozerThe ergonomics of heavy equipment seats have come a long way, especially over the last decade. Advancements in seat suspension technology and cushion comfort have made operating these large machines much more enjoyable. Many of the older dozer seats didn’t even have suspension seats, which could cause serious back issues for the operator. A very large bottom cushion was very common in the older machines, mounted to sliderails and then mounted rigid to the machine.

If it comes time to replacing these older dozer non-suspension seats, consider looking into upgrading into a suspension seat option.

There are a variety of compact suspension seats that will be a suitable replacement option without adding height. This will give you the benefit of the shock absorbing suspension which will help reduce back pain over the static seat.   If your machine came with a mechanical suspension seat and it needs to be replaced, consider upgrading to a 24V air ride suspension seat. Most of the latest dozers and wheel loaders are coming standard with an air suspension seat. Air suspension seats have better vibration absorption than mechanical suspensions. They are also much easier to adjust when switching from one operator to the next. Most dozers and loaders will not have an air source in the cab.  So if upgrading to air suspension seat, make sure you look for a seat with a built in 24V compressor (verify voltage- some are 12V).

Another trend with newer dozers and loaders is that most are now coming with highback seats over the midback seats. Midback seats were very common in older machines, but the highback seat has become more and more popular as operators realize the benefit of the extra back support that comes from the higher back.

You don’t have to settle for what seat came original in your machine when it comes time to replace your suspension seat. Contact an application specialist at to find out what upgrade options are available for your dozer seat or loader seat.

Weight Capacity of Heavy Equipment Seats

A common reason heavy equipment seats get replaced is due to the suspension failing. A common cause of this is that the original factory seat very often comes with a mechanical suspension seat with a low operator weight capacity. Common weight ratings of factory seats in heavy equipment are 265lbs-285lbs. The problem is when you get an operator that is over the weight capacity, this will cause the suspension to “bottom out”. When in a rough application such as in a dozer seat, loader seat, or haul truck seat, the suspension will bounce off the bottom causing very rapid wear of the suspension. This is also not a very fun ride for the equipment operator and his back.

The way to help reduce how often you are replacing suspension seats, is next time replace it with a seat with a weight capacity that can handle the heaviest operator you have for that machine. There are mechanical suspension seats rated up to 385lbs. and extreme duty air ride suspension seats rated up to 400lbs. By doing this the suspension seat will not bottom out, greatly increasing the life of the suspension and the comfort of the operator. Visit to see our 400lbs. rated seats or call and speak with an application specialists to find a seat that meets your requirements.

Suspension seat solutions for forklift operators suffering from back pain

Many forklifts especially the older ones come with seats that have no suspension. This makes for a bumpy ride depending on the floor surface. This creates a lot of vibration that gets transferred to the forklift operators back. For some forkift operators that have been operating for years, the constant exposure to ride shock and vibration leads to chronic back pain. Many companies spend an enormous amount of money for workers compensation claims on forklift operators due to chronic back pain.

Research has shown that a good compact suspension seat reduces a great amount of shock and vibration exposure to the forklift operator. The aftermarket now has many different models of compact suspension seats available to fit most forklifts. Since these seats have very compact suspensions, the height of the seat is not really affected compared to the orignal non-suspension seat. There are 12V air suspension seats and mechanical suspension seats for forklifts. The 12V air suspensions which are more expensive than the mechanical suspensions deliver the best vibration reduction. The air ride suspension is also much easier for different sized operators to adjust for their weight vs. the mechanical.

The difference in ride comfort from the most economical suspension seat to the most expensive can vary greatly. A more comfortable forklift operator results in a more productive operator. Be sure to check with an application specialist at Industrial Seats to help you determine which seats would be best for you and that will fit your forklift. These forklift seats can be viewed on

Why 4 Point Harness Seats are gaining popularity in heavy equipment?

4 Point Harness Seats offer several advantages over traditional lap seat belts common in heavy equipment.   The crash forces are spread over the skeletal body over more points than the standard lap belt.  The crash forces are spread to the strongest parts of the body.  Forward head excursion (the distance the head is thrown forward) are lessened.

Traditional harness belts allow little to no moving around once strapped.   There are newer harness belt seats that feature an inertia reel, which allows your harness belt to function like your stock belt.  That means you can still move around but it will lock under sudden movement or jolt.  These newer harness belt seats also buckle at one point like a standard lap belt which makes for easy in and out of the seat.

For off-highway equipment, be sure to check the 4 point harness seat meets SAE J2292 and SAE J386 which are off-highway harness and seat belt restraint requirements.   There should be tags marked for inspection.   Check with the people at Industrial Seats, Inc. on their newest 4 point harness seat offerings that meet these off-highway requirements.   They can help you find a 4 point harness seat that fits your application on
