A twin engined Terex TS-14b scraper in Hudson, Ohio. In civil engineering, a wheel tractor-scraper (also known as a land scraper, land leveler or tournapull) is a type of heavy equipment used for earthmoving. It has a pan/hopper for loading and carrying material.
The Terex THS15 Motorscraper was a concept machine scraper displayed for the first time at Minexpo 2000.This machine features some unusual design concepts, including an adjustable cutting edge on the bowl to reduce friction when loading.
Belt grinding is an abrasive machining process used on metals and other materials. It is typically used as a finishing process in industry. A belt, coated in abrasive material, is run over the surface to be processed in order to remove material or produce the desired finish.

A scraper pig shown at the Trans-Alaska Pipeline System Visitors Center. In pipeline transportation, pigging is the practice of using pipeline inspection gauges or gadgets, devices generally referred to as pigs or scrapers, to perform various maintenance operations. This is done without stopping the flow of the product in the pipeline.
A drawback to belt drives is that they transmit less power than gears or chain drives. However, improvements in belt engineering allow use of belts in systems that formerly only allowed chain drives or gears. Power transmitted between a belt and a pulley is expressed as the product of difference of tension and belt velocity:
