Romans improved upon the types of cranes used in ancient Greece. Roman cranes allowed a pair of operators to lift a remarkable 6,000 kg.

Cranes as we know them today can be traced back to 1838 when William Armstrong invented the first hydraulic crane.

ADVANTAGE AND DISADVANTAGE OF HYDRAULIC CRANE?

  • ADVANTAGES :
  • 1-small size equipment
  • 2-Good for lifting heavy load
  • 3-easy to use

​

  • DISADVANTAGES:
  • 1- Oil leakage
  • 2- Quick over heated

COMPONENTS OF HYDRAULIC CRANE SYSTEM:

  • Most designs are the same or have slightly different variations due to size and weight allowance but the frame and structure of how they are made up should be relatively the same.�
  • FRAME �- The frame is made up of multiple� metal plates that hold the hydraulic� system . �

LEGS :

  • There are two types of legs that are regular and adjustable.�

WHEELS

  • In most cases, you will find they have four wheels with two nearly directly under the main upward support frame and a hydraulic cylinder with the other two on each end of the legs.

BOOM:

�

  • A crane boom is a long fixed or hydraulic arm that is used to move large objects in construction.�

CHAIN:

  • Chains are also used on construction sites where they can lift loads from the higher levels, in assembly line factories.�������

HOOK:

  • These are the overhanging parts that come off the main bar and allow it to pick up items, move the items, and lower the items with ease. �

HYDRAULIC JACK

  • The hydraulic jack is operated through a lever and the bigger the weight its lifting and carrying, the longer this can take as it's being required to lift and hold an increased weight.

Stress Analysis

Equations:�∑MA=0

FY×450-P×L=0

FY=(10000×1000)/450�=23KN� F=Fy/(sin45◦)=32KN

FX=cos45°×F=23KN

Conclusion:

  • for many years, cranes have designed for lifting heavy objects with different capacity in different work sites.
  • hydraulic cranes are not type of cranes designed for lifting objects, which are beyond the capacity of human being.
  • practicable of this lifting operation by using portable and moveable crane.
