2. Hydraulic pump - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_pump

   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 ...

3. Hydraulic hooklift hoist - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_hooklift_hoist

   The North American market developed low pressure / high volume systems, which allowed operators to share the hoist's hydraulic system with other hydraulically powered devices. These systems typically operate with a larger gear pump and larger hydraulic reservoir. Operating pressures range from 2,000 to 3,500 psi (14,000 to 24,000 kPa).

4. Hydraulic machinery - Wikipedia

   The cylinder areas, motor displacements and mechanical torque arms must be designed to match load pressure in order to bring down the power losses. Pump pressure always equals the maximum load pressure when several functions are run simultaneously and the power input to the pump equals the (max. load pressure + Δp LS) x sum of flow.

5. Dump truck - Wikipedia

   en.wikipedia.org/wiki/Dump_truck

   6×4 semi-tractor with two-axle trailer. A semi end dump is a tractor-trailer combination wherein the trailer itself contains the hydraulic hoist. In the US a typical semi end dump has a 3-axle tractor pulling a 2-axle trailer with dual tires, in the EU trailers often have 3 axles and single tires. The key advantage of a semi end dump is a ...

   These are operative at a medium voltage of 380 to 550 volts. Flexible trailing cables are provided with a reeling/unreeling facility to feed power. These drives operate hydraulic pumps and hydraulic motors for further operation of the various movements of buckets and vehicle traction and steering. The speed of the vehicle is controlled ...
