When it comes to lifting and moving heavy materials on construction sites, various types of cranes serve specific purposes based on their design, operation, and application. Derrick cranes, hammerhead tower cranes, and flat-top cranes are three commonly used types of cranes. Understanding their differences can help in selecting the right crane for your project needs.
Structural Characteristics:
Derrick cranes are known for their movable boom (jib) that can pivot up and down in a vertical plane.
They typically have a fixed mast and a boom that can be raised or lowered.
Operational Features:
The height and radius of the lift can be adjusted by changing the angle of the boom.
These cranes are suitable for tasks that require frequent adjustments of lifting angles and heights.
Applications:
Commonly used in ports, construction sites, factories, and other environments where frequent loading and unloading are required.
Ideal for locations with space constraints or where a large working radius is needed
Structural Characteristics:
Hammerhead tower cranes feature a fixed tower and a horizontal jib that extends from the tower top.
The mast and tower head are fixed and do not pivot like a derrick crane.
Operational Features:
The lifting position is adjusted by rotating the jib horizontally and moving the trolley along the jib.
The lifting height and working radius are relatively fixed, providing less flexibility compared to derrick cranes.
Applications:
Suitable for high-rise building construction, large construction sites, and tasks requiring substantial lifting capacity.
The fixed tower head offers stability and efficiency for heavy-duty lifting operations.
Structural Characteristics:
Flat-top cranes lack the traditional tower head, with the jib and tower top aligned at the same height.
The absence of a tower head results in a more streamlined structure.
Operational Features:
The jib rotates horizontally, and the lifting position is adjusted by moving the trolley.
Easier to assemble, disassemble, and transport due to the simplified structure, making them suitable for tight spaces.
Applications:
Frequently used in urban construction sites, bridge construction, and projects requiring multiple cranes working in tandem.
The compact design makes them ideal for operations in confined spaces.
