Types of excavating tools and machine

  1. 1. Excavation Related Machineries
  2. 2. Excavation Related Machineries Power Shovel Dragline Clam Shell Back Hoe Trenching Machine
  3. 3. Power Shovel
  4. 4. 7/19/2015 4 POWER SHOVELS  Power Shovels are used primarily to excavate earth and load it into trucks.  They are capable of excavating all classes of earth, except solid rock, without prior loosening, like in quarries, mines in any road projects etc.  Power shovels are considered as basic tool for excavating the materials and loading.  They may be mounted on crawler tracks, in which case they are referred to as crawler mounted shovels. Such shovels have very low travel speeds.  However, they may be mounted an rubber-tired wheels. Single-engine self-propelled units are powered and operated from excavator cab. The non-self-propelled units mounted on the rear of tracks, which are referred to as truck- mounted, have separate engines for operating them.
  5. 5. Dragline
  6. 6. Dragline A dragline excavator is especially useful when there is need for extended reach in excavating or when material must be excavated from underwater. Draglines are used to excavate material and load it into hauling units or to deposit it in levees and spoil piles near the pits from which it is excavated.
  7. 7. DRAGLINE BUCKET A dragline bucket consists of three parts: the basket, the arch, and the cutting edge. Buckets are generally available in three types: (1) light duty, (2) medium duty, and (3) heavy duty.
  8. 8. Clam Shell
  9. 9. Clamshells are used primarily to remove materials from vertical excavations such as cofferdams, pier foundations, and sheet-lined trenches. There are hydraulic clamshell buckets that are mounted on the stick of hydraulic hoes. The two jaws of a clamshell bucket clamp together when the bucket is lifted by the closing line.
  10. 10. Back Hoe
  11. 11. Back Hoe A backhoe, also called a rear actor or back actor, is a piece of excavating equipment or digger consisting of a digging bucket on the end of a two-part articulated arm. The section of the arm closest to the vehicle is known as the boom, and the section which carries the bucket is known as the dipper or dipper-stick .  The boom is generally attached to the vehicle through a pivot known as the king-post, which allows the arm to slew left and right, usually through a total of around 200 degrees.
  12. 12. Trenching Machine
  13. 13. Trenching Machine A trencher is a piece of construction equipment used to dig trenches, especially for laying pipes or cables, for installing drainage, or in preparation for trench warfare. Trenchers may range in size from walk- behind models, to attachments for a skid loader or tractor, to very heavy tracked heavy equipment.
