• For large tower cranes, the concrete pad can be up to 30′ by 30′ and 4′ deep, with a pad weight of up to 400,000 lb[4].

Mast (Tower)

• The mast is the vertical structure constructed using steel lattice segments that are assembled on-site to achieve the required height. It supports the operator’s cab, the hook, and the counterweights[2][4].

Turntable

• Located at the top of the mast, the turntable enables the jib to rotate 360 degrees, allowing for precise positioning of loads across the construction site[2][4].

Jib (Working Arm)

• The jib is the horizontal component that extends from the top of the tower, supporting and positioning the load. It can extend outwards and move loads horizontally[2][4].

Counter Jib

• The counter jib extends in the opposite direction of the jib and helps balance the crane by counteracting the weight of the load. It also mounts the counterweights, typically made of reinforced concrete and steel[2][4].

Trolley and Hook Block

• The trolley moves back and forth along the jib, and the hook block, attached to the trolley, functions as a pulley system. This allows the hook to travel vertically up and down the tower, facilitating the lifting and lowering of loads[2][4].

Operator’s Cab

• The operator’s cab is the control center of the crane, housing the operator and the necessary control systems, including joysticks and computers. From this vantage point, the operator can execute complex lifting and positioning tasks with precision[2][4].

Operating Mechanisms

Load Management

• Load management relies on precision and balance. The crane’s design, including its lattice structure and counterweights, ensures effective tension management during lifting operations. The trolley and pulley system allow for smooth and precise movement of the load[2][4].

Rotation and Positioning

• The turntable and slewing bearing ring enable the crane to rotate 360 degrees, while the jib and trolley system allow for horizontal and vertical movement of the load[2][4].

Selection Criteria for Stationary Tower Cranes

Working Radius

Maximum Height

• The height required under the hook of the tower crane should be 6-10 meters more than the highest height of the building[5].

Maximum Lifting Capacity

• The maximum lifting capacity depends on the weight of the heaviest cargo lifted in a single lifting operation and its location on the floor plan[5].

Mast Section Types

• Mast sections can be fixed or split. Fixed types are cheaper but less convenient to transport, while split types are more expensive but easier to transport[5].

Installation Location

• The installation method (stationary, internal climbing, chassis weight, or traveling chassis) depends on the construction site requirements and the crane’s specifications[5].

Installation Methods

Stationary Type

• Requires a prefabricated installation foundation. This type is suitable for long-term construction projects[5].

Internal Climbing Type

• The crane is secured to the side of the building, and mast sections can be added as the building rises using a jacking system[4].

Chassis Weight Type

• Does not require a prefabricated installation foundation, making it suitable for short-term construction projects with a maximum height not exceeding 150 meters[5].

Traveling Chassis Type

• Requires laying a track and is a good choice when the height requirement is not high but the crane needs to cover a longer construction area[5].

Additional Considerations

Load Moment Indicators (LMI)

• Most tower cranes come equipped with LMI, which monitor the load to ensure it does not exceed the maximum load rating and prevent overloading[4].

Counterweights

• Concrete slabs or other heavy materials are used as counterweights to balance the crane and ensure stability during operations[2][4].

Operator Safety and Access

• The operator’s cab is typically accessed by climbing the tower crane mast, although some cranes may have an elevator lift attached to the mast sections for easier access[4].

By understanding these components, mechanisms, and selection criteria, you can make an informed decision when choosing a stationary tower crane for your construction project.

Stationary Tower Crane

Since the specific website you mentioned is not accessible in the search results provided, I will create a comprehensive guide to tower cranes based on the information from the other sources. Here is an in-depth guide to tower cranes, structured with appropriate headings and subheadings.

What Are Tower Cranes?

Tower cranes are stationary cranes used predominantly in construction projects, especially for high-rise buildings and large civil engineering works. They are distinguished by their lofty, skeletal trusses and their ability to perform precise and heavy lifting tasks.

Basic Mechanics of Tower Cranes

Base Support

The operation of a tower crane begins with the establishment of a solid base. This base can be a concrete pad or a steel structure, which provides the necessary stability and anchoring for the crane. For large tower cranes, the concrete pad can be up to 30′ by 30′ and 4′ deep, with a weight of up to 400,000 lb[4].

Tower (Mast)

Rising from the base is the mast, a vertical structure constructed using steel lattice segments. These segments are assembled on-site to achieve the required height. The mast supports crucial elements such as the operator’s cab, the hook, and the counterweights. It is designed to provide additional strength and rigidity, allowing the crane to reach significant heights without compromising stability[1][5].

Slewing Unit and Turntable

At the top of the mast is the slewing unit, which includes the turntable. The turntable enables the jib (the working arm) to rotate a full 360 degrees, providing a broad range of motion. This mechanism is essential for positioning loads accurately across the construction site[1][5].

Operating Components

Operator’s Cab

The operator’s cab is the control center of the crane, housing the operator and the necessary control systems, including joysticks and computer systems. From this vantage point, the operator can execute complex lifting and positioning tasks with precision[1][5].

Jib (Working Arm)

The jib is the horizontal component that extends from the top of the tower. Its primary function is to support and position the load being lifted. The jib can extend outwards and move loads horizontally, providing flexibility in placing materials exactly where needed on the construction site[1][5].

Trolley and Hook Block

The trolley is a movable part that travels back and forth along the jib. Attached to the trolley is the hook block, which functions as a pulley system. This arrangement allows the hook to travel vertically up and down the tower, facilitating the lifting and lowering of loads[1].

Counter Jib and Counterweights

The counter jib is the horizontal arm that extends in the opposite direction of the jib. It helps balance the crane by counteracting the weight of the load being lifted. The counter jib also serves as the mounting point for the counterweights, which are typically made of reinforced concrete and steel and are essential for maintaining the crane’s stability during operations[1][5].

Load Management

Load management in tower cranes relies heavily on precision and balance. The crane’s design ensures that tension is managed effectively during lifting operations. The trolley moves back and forth along the jib, positioning the load as needed, while the pulley system allows the hook and load to move up and down smoothly. Load moment indicators (LMI) are also used to prevent overloading and ensure the load does not extend to an unsafe distance along the jib[1][4].

Installation and Assembly

The components of a tower crane are typically hauled to the job site and assembled on-site. Mobile all-terrain cranes are often used to assemble the mast sections, jib sections, the slewing unit, and the counterweights. For exceptionally tall projects, the crane can be tied-in to the structure and then climbed to greater heights using a jacking system that adds extra mast sections as the building rises[4][5].

Operational Capabilities

Tower cranes can have maximum lifting heights of up to 300 meters and a working radius of up to 70 meters. They are available in various capacities, ranging from 5 tons to 25 tons or more. The jib sections can reach out to around 230 feet, and the maximum allowable tonnage to be lifted at the end of the jib section can be around 19.8 tons or 18 metric tons[2][4].

Safety and Maintenance

Ensuring the safety of tower crane operations is crucial. This includes regular maintenance, proper training for operators, and adherence to load charts to avoid overloading. The use of load moment indicators and secondary switches to monitor the load and its distance along the jib are critical safety features[4].

Disassembly

Once the construction project is completed, the tower crane is disassembled in the reverse order from which it was built. This process involves carefully removing the components and ensuring that all parts are safely stored or transported away from the site[5].

By understanding these core functions and components, you can appreciate how tower cranes efficiently handle heavy lifting tasks, making them indispensable tools in modern construction.
