an earth-moving machine either towed or self-propelled, essentially a box on wheels which scrapes off earth to fill the box, moves and deposits it at the discharge point
1. In addition, the earth-moving machinery listed below with a capacity exceeding 15 kW must be fitted with a rollover protective structure:
- crawler loaders or wheel loaders,
- backhoe loaders,
- crawler tractors or wheel tractors,
- scrapers, self-loading or not,
- graders,
- articulated steer dumpers.
2. Scrapers are designed for loading, hauling and dumping soil over medium to long distances in the earthmoving process. ... The three basic operating components of a scraper are the bowl, apron, and tailgate. The bowl is the load-carrying portion of the body ... bottom front ... is equipped with a replaceable cutting edge ... can be lowered to obtain the desired depth of cut or raised to clear the ground while hauling. The apron forms the front wall of the bowl and can be raised or lowered as desired. ... The tailgate or ejector usually forms the rear wall of the bowl and is moved forward to eject the load. The part of the equipment which handles the material is called the scraper. The other necessary part provides the power and is known as the prime mover. So the equipment may be called a tractor-scraper. For simplicity, the entire combination is generally just called a scraper.
