Simple design This is the same shape of a domestic form, the one-piece-standing single element, but often with an augmented size.
Mining In early developments of
mining, a large simple bucket allowed easy insertion of both miners and construction materials such as
pit props, and later extraction of miners and ore. Common terms used in various parts of the world include: Bowk; Kibble; Hoppit; Hoppet. Latterly they have been called sinking buckets, as they are now only used when sinking new mine shafts before insertion of the cage, or for emergency rescue.
Concrete bucket A
concrete bucket delivers concrete by means of a
tower crane. It has a bottom opening to allow concrete to flow out when in-place. See also
tremie.
Boom truck bucket A
boom truck (or “bucket truck”) bucket is an aerial work platform placed at the end of an excavator-like arm which allows a man to be hoisted to do construction work, such as tree pruning and electrical line maintenance. When necessary the bucket is made out of a non-conductive material for safety. A construction site
man lift is a similar apparatus. There may be a door on the side of the bucket in either.
Excavator bucket Excavator buckets are made of solid steel and generally present teeth protruding from the cutting edge, to disrupt hard material and avoid wear-and-tear of the bucket. Subsets of the excavator bucket are: the ditching bucket, trenching bucket, A ditching bucket is a wider bucket with no teeth, used for excavating larger excavations and grading stone. A trenching excavator bucket is normally wide and with protruding teeth.
Bucket crusher A
bucket crusher or crusher bucket is a type of jaw crusher. It's an attached tool for excavators for built-in crushing construction waste and demolition materials.
Screening bucket The
screening bucket is an attachment for the excavators, loaders, skid steers and backhoe loaders that helps the selection of natural material for different purposes at the jobsite.
Clamshell bucket , now displayed at a dock re-development in
Cardiff The clamshell bucket is a more sophisticated articulated several-piece device, including two elementary buckets associated on a hinged structure forming a claws-like appendage with an internal volume.
Buckets-wheel In mining The design is used in
bucket-wheel excavators. The buckets in the wheel have to be made of solid material to withstand the resistance of the material it cuts through.
In water hoisting In energy production The bucket wheel design is also used to capture the water energy in water-wheels or water turbines like
Pelton wheels. The buckets also have to be made of solid material to withstand the force of the water flow. Their shape is optimized according to their purpose. Other designs include vertical shaft wind turbines designs like on the
Savonius wind turbine. In this case, the buckets have to be made of a light material.
Buckets-ladders (buckets-chains) The buckets-ladders are used in
bucket elevators or in the dredge design of some dredgers. ==Images==
