A hydraulic fluid or hydraulic liquid is the medium by which power is transferred in hydraulic machinery. Common hydraulic fluids are based on mineral oil or water. [ 1 ] Examples of equipment that might use hydraulic fluids are excavators and backhoes , hydraulic brakes , power steering systems, automatic transmissions , garbage trucks ...
The wedge plow or Bucker plow was first developed by railroad companies to clear snow in the American West. The wedge plow forces snow to the sides of the tracks and therefore requires a large amount of force due to the compression of snow. The wedge plow is still in use today in combination with the high-maintenance rotary snowplow.
Snow plow blades are available in various sizes depending on a vehicle type. Service trucks usually use a blade sized 96 in (2.4 m) and more. Common blade size for pickup trucks and full size SUVs is 78–96 in (2.0–2.4 m). Smaller ATV snow plow blades are 48–78 in (1.2–2.0 m) wide. [citation needed]
Fisher Engineering is a subsidiary of Douglas Dynamics (NYSE:PLOW), which also owns Western Products, Blizzard, and TrynEx International, each producing their own snowplow brands. Fisher Engineering is one of the leading snow management equipment providers in the Northeastern United States. [1]
Fluid flow in an external gear pump. A hydraulic pump is a mechanical source of power that converts mechanical power into hydraulic energy (hydrostatic energy i.e. flow, pressure). Hydraulic pumps are used in hydraulic drive systems and can be hydrostatic or hydrodynamic. They generate flow with enough power to overcome pressure induced by a ...
An auxiliary hydraulic system delivers pressurized hydraulic fluid from a hydraulic pump to operate auxiliary equipment or attachments. The addition of an auxiliary hydraulic system to heavy construction equipment increases the versatility of the vehicle by allowing it to perform additional functions with different attachments.
A fluid coupling consists of three components, plus the hydraulic fluid: The housing, also known as the shell [5] (which must have an oil-tight seal around the drive shafts), contains the fluid and turbines. Two turbines (fanlike components): One connected to the input shaft; known as the pump or impeller, [5] or primary wheel input turbine. [5]
Only a few hydraulic power transmission networks are still in use; modern hydraulic equipment has a pump built into the machine. In the late 19th century, a hydraulic network might have been used in a factory, with a central steam engine or water turbine driving a pump and a system of high-pressure pipes transmitting power to various machines.
