The hydraulic fluid reservoir holds excess hydraulic fluid to accommodate volume changes from: cylinder extension and contraction, temperature driven expansion and contraction, and leaks. The reservoir is also designed to aid in separation of air from the fluid and also work as a heat accumulator to cover losses in the system when peak power is ...
Open-pit mines were electrified at this time. Only after the Second World War, with the advent of robust high-pressure hydraulic hoses, did the more versatile hydraulic excavators take pre-eminence over the cable-hoisting winch shovels. Many steam shovels remained at work on the railways of developing nations until diesel engines supplanted them.
In December 1993, VME North America entered into a joint venture of its own with Hitachi Construction Machinery Co. Ltd., called Euclid-Hitachi Heavy Equipment. Hitachi, a manufacturer of hydraulic construction machinery such as excavators and cranes, gradually increased its share of the joint venture until it owned 100% of the organization by ...

Hydraulic Flood Retention Basin (HFRB) View from Church Span Bridge, Bern, Switzerland Riprap lining a lake shore. Hydraulic engineering as a sub-discipline of civil engineering is concerned with the flow and conveyance of fluids, principally water and sewage. One feature of these systems is the extensive use of gravity as the motive force to ...
A mechanical jack employs a screw thread for lifting heavy equipment. A hydraulic jack uses hydraulic power. [1] The most common form is a car jack, floor jack or garage jack, which lifts vehicles so that maintenance can be performed. Jacks are usually rated for a maximum lifting capacity (for example, 1.5 tons or 3 tons).
In the early 1920s, Hendy's hydraulic mining equipment was used in the regrading of Seattle, [2] [6] described as perhaps the largest such alteration of urban terrain in history. [ 6 ] With the onset of the Great Depression however, and hampered by indifferent management, the Hendy Iron Works - like many other heavy equipment manufacturers of ...
