Bucyrus-Erie 50-R, 55 feet high and housing a massive drill, was used in the successful rescue of two miners during the 1963 Sheppton, Pennsylvania mining disaster. [17] 1250-B/W and 1260-W walking draglines, with buckets between 33 and 45 cu yd (25 and 34 m 3).
A cattle crush and an anti-bruise race in Australia. Chin (or neck) bar in operation during mouthing.. A cattle crush (in UK, New Zealand, Ireland, Botswana and Australia), squeeze chute (North America), cattle chute (North America), [1] [2] standing stock, or simply stock (North America, Ireland) is a strongly built stall or cage for holding cattle, horses, or other livestock safely while ...
A curved "V" (tapered) race or alley leading to a covered crush. A cattle chute (North America) or cattle race (Australia, British Isles and New Zealand) also called a run or alley, [1] is a narrow corridor built for cattle that separates them from the rest of the herd and allows handlers and veterinarians to provide medical care or restrain the animal for other procedures.
Some varieties of flumes are used in measuring water flow of a larger channel. When used to measure the flow of water in open channels, a flume is defined as a specially shaped, fixed hydraulic structure that under free-flow conditions forces flow to accelerate in such a manner that the flow rate through the flume can be characterized by a level-to-flow relationship as applied to a single head ...
The tools operate on the basis of the hydraulic fluid pressure of up to 720 bars (10,400 psi; 72 MPa), which must be provided from a power source. At present, there are three different means of generating pressure. The most commonly used source is a separate power unit, small petrol (gasoline) engine connected to a hydraulic pump.
A simple open center hydraulic circuit. An excavator; main hydraulics: Boom cylinders, swing drive, cooler fan, and trackdrive Fundamental features of using hydraulics compared to mechanics for force and torque increase/decrease in a transmission. Hydraulic machines use liquid fluid power to perform work. Heavy construction vehicles are a ...
A hydraulic cylinder is the actuator or "motor" side of this system. The "generator" side of the hydraulic system is the hydraulic pump which delivers a fixed or regulated flow of oil to the hydraulic cylinder, to move the piston. There are three types of pump widely used: hydraulic hand pump, hydraulic air pump, and hydraulic electric pump.
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 ...
