Rotopactor Machine

Additional Details

We are one of the leading manufacturers, suppliers, wholesalers and exporters of optimum quality Rotopactor Machine. Manufactured as per the industry set standards, these rotapactors are widely used for crushing stones into the desired sizes. Due to their impeccable performance and low maintenance, these stone crushers are highly demanded in the market.
Heavy equipment refers to heavy-duty vehicles, specially designed for executing construction tasks, most frequently ones involving earthwork operations. They are also known as, heavy machines, heavy trucks, construction equipment, engineering equipment, heavy vehicles, or heavy hydraulics. They usually comprise five equipment systems: implement, traction, structure, power train, control and information. Heavy equipment functions through the mechanical advantage of a simple machine, the ratio between input force applied and force exerted is multiplied.Currently most equipment use hydraulic drives as a primary source of motion.
The use of heavy equipment has a long history; the ancient Roman engineer Vitruvius (1st century BCE) gave descriptions of heavy equipment and cranes in ancient Rome in his treatise De architectura. The pile driver was invented around 1500. The first tunnelling shield was patented by Isambard Kingdom Brunel in 1818.

From horses, through steam, to diesel

Until the 19th century and into the early 20th century heavy machines were drawn under human or animal power. With the advent of portable steam-powered engines the drawn machine precursors were reconfigured with the new engines, such as the combine harvester. The design of a core tractor evolved around the new steam power source into a new machine core traction engine, that can be configured as the steam tractor and the steamroller. During the 20th century, internal-combustion engines became the major power source of heavy equipment. Kerosene, ethanol and gasoline engines were used, but today diesel engines are dominant. Mechanical transmission was in many cases replaced by hydraulic machinery. The early 20th century also saw new electric-powered machines such as the forklift. Caterpillar Inc. is a present-day brand from these days, starting out as the Holt Manufacturing Company. The first mass-produced heavy machine was the Fordson tractor in 1917.

The first commercial continuous track vehicle was the Lombard Steam Log Hauler from 1901. Tracks became extensively used for tanks during World War I, and after the war they became commonplace for civilian machinery such as the bulldozer. The largest engineering vehicles, and the largest mobile land machines altogether, are bucket-wheel excavators, built from the 1920s.

"Until almost the twentieth century, one simple tool constituted the primary earthmoving machine: the hand shovel - moved with animal and human powered, sleds, barges, and wagons. This tool was the principal method by which material was either sidecast or elevated to load a conveyance, usually a wheelbarrow, or a cart or wagon drawn by a draft animal. In antiquity, an equivalent of the hand shovel or hoe and head basket—and masses of men—were used to move earth to build civil works. Builders have long used the inclined plane, levers, and ignorant to place solid building materials, but these labor-saving devices did not lend themselves to earthmoving, which required digging, raising, moving, and placing loose materials. The two elements required for mechanized earthmoving, then as now, were an independent power source and off-road mobility, neither of which could be provided by the technology of that time."

Container cranes were used from the 1950s and onwards, and made containerization possible.

Nowadays such is the importance of the machinery, transport companies- in particular Van der Vlist have developed specific equipment to be able to efficiently transport the equipment to and from sites.
