This document provides an overview of various types of earth moving and hoisting equipment, including cranes, tractors, scrapers, draglines, and clam-shell buckets. It describes the main components and uses of stationary and mobile cranes, tower cranes, overhead cranes, tractors, scrapers, draglines, and clam-shell buckets. The document explains that cranes can provide three-dimensional movement of weights and are used for heavy lifting in construction. Tractors are used to pull and push other equipment. Scrapers are self-operating machines for digging and long-distance hauling. Draglines and clam-shell buckets are suitable for excavating softer materials below track level.

1. A PRESENTATION ON
HOISTING EQUIPMENT- EARTH WORK EQUIPMENT
BY
B.MAHESHBABU

2.  HOISTING EQUIPMENT
 HOISTS-CRANES
 TRACTORS
 SCRAPERS
 DRAGLINES
 CLAM-SHELL BUCKETS

3.  Hoisting is the lifting a weight from one
location and moving it to another location
which is at a reasonable distance.
 Big projects such as dams,industrial builindgs
Require hoisting equipment, which includes
jacks,winches,chain hoists and cranes

6.  CRANE IS THE ONLY SINGLE MACHINE WHICH
IS SINGLE PIECE CAPABLE OF PROVIDING
THREE DIMENSIONAL (360 degree) MOVEMENT
OF WEIGHT IS CALLED A CRANE

7.  STATIONARY OR DERRICK CRANES
 MOBILE CRANES
 OVERHEAD OR GANTRY CRANES
 TOWER CRANES

11.  DERRICK CRANE CONSISTS OF MAJOR PARTS
LIKE
CRAWLER,MAST,SUPERSTRUCTURE,COUNTERW
EIGHT,JIB,PULLEY
 ELECTRICALLY OPERATED,DISEIL OPERATED,
DIESIEL-ELECTRICAL OPERATED
 THE BOOM CAN REVOLVE 360 Degrees
 THIS CRANE IS USED FOR HEAVY LOADS UPTO
200 TONS

12.  A DERRICK CRANES MAY BE USED ON A WIDE
RANGE OF WORKS
 INDUSTRIAL BUILDINGS
 CONSTRUCTION OF HIGH RISE BUILDINGS
 ERECTION OF STEEL AND INDUSTRIAL PLANTS
 HANDLING TIMBER
 HOISTING WORKS AT SHIP YARDS
 LOADING AND UNLOADING AT SHIPYARDS
 CARGOS AT PORTS

16.  CRAWLER
 TYRE TYPE
 ROUGH TERRAIN

17.  THESE CRANES ARE MOUNTED ON MOBILE
UNITS WHICH IS EITHER TYRE TYPE OR
CRAWLER TYPE
 TRUCK CRANES HAVE HIGH MOBILITY WHILE
THE CRAWLER MOUNTED CRANES MOVE
SLOWLY
 CRAWLER MOUNTED CRANES ARE CAPABLE OF
MOVING ON ROUGH TERRAIN

18.  WHEEL TYPER CRANES USED FOR LIFTING
LOW LOAD CAPCITY MATERIALS
 USED TO LIFT THE CONCRETE GIRDERS, LIGHT
STEEL AND WOOD MATERIALS
 WORKING AND LIFTING MATERIALS AT DEEP
VALLY AND HIGH RISE BUILIDINGS
 LIFTING VEHICLES AT ACCIDENT AREAS AND
CLEARING THE VECHILCES IN JAMMED AREAS
 LIFTING LIGHT WEIGHT SLEEPERS IN RAILWAYS
 CRAWLER TYPE USED AT ROUGH AND WET
TERRAINS FOR THE SAME PURPOSES ABOVE

22.  THESE TYPE CRANES CONSITS OF TWO MAJOR
PARTS : BRIDGE AND CRAB
 THE BRIDGE CONSISTS OF TWO MAIN GIRDERS
AT THEIR END TO END AND CAPABLE OF
MOVING ON GANTRY RAILS
 THE CRAB CONSISTS OF THE HOISTING GEAR
MOUNTED ON FRAME
 FREE OF MOVING IN ANY DIRECTION
 NO OBSTACLES IN LIFTING
 LIMITED TO CERTAIN HEIGHT

23.  THESE CRANES ARE USED FOR HANDLING
LOADS OVER A LONG RECATANGULAR AREA
SUCH AS IN FACORIES AND WORKSHOPS TO
MOVE MACHINES AND OTHER LOADS IN ANY
DIRECTION
 THESE CRANES CONSIST OF HOISTING
MECHANISM MOUNTED ON A CARRIAGE
 CAPICITY 0.99 TO 455 Metric tonnes
 LARGE SEVICE AREA
 FREEDOM FROM FLOOR AREA

24.  WIDLEY USED IN ERECTION ,FOUNDRY, STEEL
PLANTS, STORAGE YARDS

28.  IN APPEARNCE MOST OF TOWER CRANES LOOK
ALIKE BUT THEY ARE NOT SAME TYPE
 VARIOUS TYPES OF TOWER CRANES ARE
AVAILABLE IN THE MARKET AND IT IS
IMPORTANT TO CHOOSE THE RIGHT TOWER
CRANE FOR A PROJECT.
 THE TOWER CRANES HAVE MORE
ADAVANTAGES THAN CONVENTIONAL CRANES
 THE LIFTING CAPACITY IS ONE OF THE
IMPORTANT SLECTION PARAMETER BESIDES
LENGTH OF RADIUS,MAXIMUM HOOK HEIGHT
ABVOVE GROUND

29.  THE USE OF TOWER CRANE HAS BECOME
PROMINENT WITH MEDIUM TO HIGH RISE
CONSTRUCTIONS
 BRIDGES ,DAMS, TOWERS(COMMUNICATION)
 TOWER CRANES CAN BE FIXED ON RAILS ONLY
 EXCELLENT BEARING OF LOAD AND ITS
SURROUNDINGS AT ALL TIMES

30.  MULTI-PURPOSE MACHINES USED MAINLY
PULLING AND PUSHING OTHER EQUIPMENTS
TRACTORS MAYBLE CLASSIFED INTO TWO
 CRAWLER TYPE
 WHEEL TYPE

31.  CRAWLER TYPE : USED TO MOVE
BULLDOZERS,SCRAPERS
 THE CRAWLER HAS A CHAIN BY WHICH THESE
TRACTORS CAN BE VERY EFFECTIVE EVEN IN THE
CASE OF LOOSE OR MUDDY SOILS. THE SPEED OF
THIS TYPE DOSE NOT EXCEED 12 KMPH
NORMALLY.
 WHEEL TYPE :THE ENGINE IS MOUNTED ON FOUR
WHEELS. THE MAIN ADVANTAGE IS HIGHER SPEED,
SOMETIMES EXCEEDING 50 KMPH IT IS USED FOR
LONG-DISTANCE HAULING AND GOOD ROADS

36.  UNIQUE MACHINE FOR DIGGING AND LONG-
DISTANCE HAULING OF PLOUGH ABLE
MATERIALS.
 SELF-OPERATING MACHINE
 A WHEEL TRACTOR-SCRAPER IS A PIECE
OF HEAVY EQUIPMENT USED
FOR EARTHMOVING
 IT IS NOT DEPENDENT ON OTHER EQUIPMENT.
 WHEELS OF MACHINE CAUSE SOME
COMPACTION
 THE BASIC PARTS OF SCRAPERS ARE THE
BOWL, APRON AND TAIL GATE OR EJECTOR

37.  USED FOR EARTH MOVING
 TRIMMING THE SMALL EARTH CUTTINGS
 GRADING AND SMALL COMPACTION FOR
LARGE HAULS

40.  THE DRAG LINE IS SO NAME BECAUSE OF ITS
PROMINENT OPERATION OF DRAGGING THE
BUCKET AGAINST THE MATERIAL TO BE DUG
 UNLIKE THE SHOVEL, IT HAS A LONG LIGHT
CRANE BOOM AND THE BUCKET IS LOOSELY
ATTACHED TO THE BOOM THROUGH CABLES
 BECAUSE OF THIS CONSTRUCTION, A
DRAGLINE CAN DIG AND DUMP OVER LARGER
DISTANCES THAN A SHOVEL CAN DO

41.  DRAG LINES ARE USEFUL FOR DIGGING
BELOW ITS TRACK LEVEL AND HANDLING
SOFTER MATERIALS.
 THE BASIC PARTS OF A DRAG LINE INCLUDING
THE BOOM, HOIST CABLE, DRAG CABLE,
HOIST CHAIN, DRAG CHAIN AND BUCKET.

43.  IT IS THE MOST SUITABLE MACHINE FOR
DRAGGING SOFTER MATERIAL AND BELOW ITS
TRACK LEVEL
 IT IS VERY USEFUL FOR EXCAVATING
TRENCHES WHEN THE SIDES ARE PERMITTED
TO ESTABLISH THEIR ANGLE OF REPOSE
WITHOUT SHORING
 IT IS MOSTLY USED IN THE EXCAVATION FOR
CANALS AND DEPOSITING ON THE
EMBANKMENT WITHOUT HAULING UNITS

47.  THIS IS SO NAMED DUE TO RESEMBLANCE OF ITS
BUCKET TO A CLAM WHICH IS LIKE A SHELL-FISH
WITH HINGED DOUBLE SHELL
 THE FRONT END IS ESSENTIALLY A CRANE BOOM
WITH A SPECIALLY DESIGNED BUCKET LOOSELY
ATTACHED AT THE END THROUGH CABLES AS IN A
DRAG LINE.
 THE CAPACITY OF A CLAM SHELL BUCKET IS
USUALLY GIVEN IN CUBIC METERS
 THE BASIC PARTS OF CLAM SHELL BUCKET ARE
THE CLOSING LINE, HOIST LINE, SHEAVES,
BRACKETS, TAGLINE, SHELL AND HINGE.

50.  USED FOR HANDLING LOOSE MATERIAL SUCH
AS CRUSHED STONE, SAND, GRAVEL, COAL
ETC.
 MAIN FEATURE IS VERTICAL LIFTING OF
MATERIAL FROM ONE LOCATION TO ANOTHER.
 MAIN FEATURE IS VERTICAL LIFTING OF
MATERIAL FROM ONE LOCATION TO ANOTHER.
