The Many Advantages of Harness Seats

Heavy equipment operator safety is always a concern with construction and mining companies.   Making sure the operator is buckled in with a standard lap belt is required and in many of the cases can protect the operator from serious injury.   One thing a lap belt can’t prevent is the operator’s torso from jolting forward in a front end collision or turnover.   This can result in serious head injuries to the equipment operator.   Harness seats are becoming the uncontested solution for this issue.   The benefits of harness seat over the tradition lap belt are bountiful, and include:

    • The crash forces are spread over the skeletal body, distributing between 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.   Many harness belt seats 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.
    • Most 3 and  4 point harness belts buckle at one point like a standard lap belt which makes for easy in and out of the seat.
    • Many harness seats offered meet ISO 7096, accommodate drivers weighing 110lbs.-330lbs. and are easily fitted to a wide range of machines (Including wheel loaders, articulated dump-trucks and dozers).

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 IndustrialSeats.com.  e sometimes offset or swivel and come with in a variety of heights depending on the model Scraper.
