Erecting cranes, especially large tower cranes, is a complex process that requires proper planning, expert coordination, and specialized equipment. Whether it is a towering structure at a construction site or a mobile crane prepared for a specific task, setting up cranes involves multiple steps to ensure safety and efficiency. Let’s explore how cranes are put up.
Types of Cranes and Their Setup
Different types of cranes have distinct setup procedures. Here is the setup of two common types: tower cranes and mobile cranes.
Setting Up Tower Cranes
Site Preparation
Survey and Foundation: The first step in erecting a tower crane is conducting a thorough site survey to determine the best location. The ground is then prepared, and a substantial concrete foundation is poured. This foundation needs to be incredibly strong to support the crane’s weight and the loads it will lift.
Assembling the Base and Mast
Base Assembly: The base of the tower crane is anchored to the foundation using large anchor bolts. This base typically includes the first section of the mast.
Mast Sections: Using a mobile crane, additional sections of the mast are lifted and bolted to the base. This process is repeated until the desired height is reached. Each section must be carefully aligned and secured to ensure stability.
Adding the Slewing Unit and Jib
Slewing Unit: The slewing unit, which allows the crane to rotate, is then installed on top of the mast. This unit is crucial for the crane’s operation.
Jib Installation: The jib and the counter-jib are assembled on the ground and then lifted into place using a mobile crane. These components are attached to the slewing unit and balanced with counterweights.
Electrical and Safety Systems
Electrical Setup: The crane’s electrical systems, including controls and power supply, are connected. This step also involves setting up communication systems for the operator.
Safety Checks: Extensive safety checks are conducted to ensure all components are secure, and the crane is functioning correctly. This includes load testing and verifying the operation of emergency systems.
Setting Up Mobile Cranes
Transportation and Positioning
Transport to Site: Mobile cranes are transported to the job site on flatbed trucks. Depending on the size, some disassembly may be required for transportation.
Positioning: Upon arrival, the crane is positioned in the exact location where it will be used. This positioning is crucial for ensuring stability and efficiency.
Deploying Outriggers and Stabilizers
Outriggers: The crane’s outriggers are extended to provide a stable base. These outriggers are essential for distributing the weight of the crane and its loads.
Leveling: The crane is leveled using hydraulic jacks on the outriggers, ensuring that it operates safely on uneven ground.
Boom Assembly
Telescoping Boom: For cranes with a telescoping boom, the boom sections are extended and locked into place.
Lattice Boom: For lattice boom cranes, sections of the boom are assembled on the ground and then lifted into place by the crane itself or with the assistance of another crane.
Counterweights and Testing
Adding Counterweights: Counterweights are added to the rear of the crane to balance the load. These are important for preventing the crane from tipping.
Testing: The crane undergoes operational tests to ensure all systems are functioning correctly. This includes lifting test loads to verify stability and control.
