What are the folders?

For most construction sites, materials such as gravel, sand and impurities are filled, while waste materials such as old bricks and dug dirt must be carried out. Most of this work is done with specialized vehicles called folders. The folders can be as small as a standard passenger car or as large as 18. They are characterized by a robust back of the rear wagons with an open gate at one end and a hydraulic elevator on the other. Hlapne cars

are commonly used to transport free materials that could not be supported in an open bed truck. Quarry or other supplier can use the front -end or upper hopper loaders to fill the folders on the capacity, then some form of protective cover can be used to prevent the residues from falling out during transport. Once the tipper reaches their destination, the rear gate is released and the hydraulic elevator raises the front of the bed. The material is usually left in piles near the area of ​​the building.

Some snacks useAny other type of bed to store materials in rows. The rear assembly looks like a metal hopper with several naval infusions leading to the ground. Instead of lifting the connected hopper, these folders reduce the rows when the material pours out of the bottom. This can be a useful function whenever a small amount of material is needed on a large area, for example for the construction of the road.

folders may have a strict assembly, with the bed and cabin forming one vehicle, or can be articulated so that the bed can be removed from the main cabin. Some folders also pull a smaller trailer, commonly called a puppy, in order to unload the material into phases. The puppy is filled to the capacity and transported to the construction site another towing system. Once the content is emptied, the puppy returns for replenishment. This prevents folders from having to travel too far to the building zone.
