Tips to Maintain Wheel Tractor Scraper

What are the Tips to Maintain Wheel Tractor Scraper? Wheel tractor-scrapers are extremely useful in the mining and aggregate industries because they can transport large amounts of material over long distances without the use of traditional loading tools.

All scrapers are built to last, but they contain a lot of moving parts and must be carefully maintained to ensure continuous performance and high production. Here are three suggestions for keeping a wheel tractor-scraper in good working order.

Selecting the best wheel tractor-scraper

To keep maintenance expenses low, it’s vital to have the correct machine for the job. Wheel tractor-scrapers come in a variety of designs, giving mine operators the option of increasing production while lowering costs by selecting the proper machine. Open bowl and elevating loading variants are available. The ideal scraper for the job is determined by the conditions on the construction site.

The point of multiple filter changes is defined by 500 hours. The engine oil and filter, as well as the fuel system filter, hydraulic oil filter, and transmission oil filter, should all be replaced at that interval.

When the grades are gentle and the underfoot conditions are ideal, a single-engine scraper can operate at maximum speed and at the lowest cost. The single-engine scraper loads faster and hauls to the fill with the help of a push tractor, while hauling the least amount of iron and consuming the least amount of gasoline. Although the push tractor provides the principal loading power, loading costs are still lower than those associated with truck loading systems.

Tandem-powered scrapers are the answer if the site has grades higher than 5% on the haul and 12% when returning empty. Twin-engine scrapers can scale up grades by up to 35% thanks to their increased horsepower-to-weight ratio. In addition, four-wheel drive scrapers can navigate underfoot terrain that would stop two-wheel-drive vehicles. The twin-engine scrapers’ capacity to work in bad underfoot conditions can result in additional workdays per year. Because tandem-powered scrapers have superior grade ability and more useful rim pull, they can minimize cycle times. Out of the cut and away from the fill, acceleration is faster. Despite the fact that greater ownership and running expenses offset the increased productivity, tandem-powered scrapers may still have the lowest cost per yard. Most wheel tractor-scraper models have daily service recommendations that call for lubricated components.

Observantly examining

The recommended maintenance procedures and the frequency with which each procedure must be conducted should be found in the operation and maintenance handbook for each individual model of wheel tractor-scraper. Because there are so many different scraper configurations — open bowl, elevating, auger, single engine, twin engine, push-pull — different maintenance items are required.

By performing a thorough pre-shift inspection of the machine, the operator can help prevent minor issues from becoming major ones. In addition to doing routine fluid level checks, the operator should pay close attention to the components that perform the most effort. On the bail, ejector, ejector rollers, and cutting edge, the operator should inspect for damage, fractured welds, and deformation. Damage to the hitch pins and brakes should also be checked, as should the tires for damage and adequate pressure.

Any debris that are obstructing airflow or wrapping around moving elements should be removed. Operators should, of course, promptly report any damage that jeopardizes the machine’s safety or health.

Preventative maintenance is important.

Most wheel tractor-scraper models have daily service recommendations that call for lubricated components. Scrapers with augers and elevating scrapers have a number of lubrication requirements that open-bowl machines do not. Maintenance operations can be carried out on a daily basis by properly educated and equipped operators or service experts. Similarly, the water separator in the fuel system and the water and sediment in the fuel tank should be drained every day.

The bowl lift cylinder bearings and the hitch should be lubricated every 50 service hours or once a week. Oil samples should be taken at 250 service hours for the engine, transmission, and hydraulic systems. Prompt oil analysis and reporting can assist detect a problem before it causes harm to components. A cooling system coolant sample should be taken and evaluated after 500 service hours.

The selection and maintenance of Ground Engaging Tools is an often overlooked part of scraper operation and maintenance (GET). There are a variety of choices for optimizing the machine for various material types and loading situations. Average, serrated, and abrasion-resistant materials are among the GET possibilities. Most are reversible, which means they’ll last longer and cost less to run.

Operations can acquire cut-rate, high-production results from their wheel-tractor scrapers by selecting appropriate equipment, paying close attention to detail during exams, and adhering to the preventive maintenance guiding concept
