7. Crane Configurations

Different types of cranes are available. You can classify it from different perspective. So, basically, the crane is classified into 2 important categories based on mobility. One is mobile crane; other one is tower crane. So, when compared to mobile crane, your tower crane has relatively lesser mobility.

Cranes are essential for lifting and moving materials at construction sites. The two primary categories of cranes are mobile cranes and tower cranes. Mobile cranes can move freely and are used in various locations, whereas tower cranes are typically fixed in place and are often used for tall buildings or large construction projects. Simply put, mobile cranes are versatile, while tower cranes provide stability and height.

Think of a mobile crane like a pickup truck, which can transport materials to various locations easily. On the other hand, a tower crane resembles a tall, stable office building that can lift materials to great heights but cannot move itself around.

The tower cranes can be further classified based upon the base type into static and travelling. That means static means; your tower crane is fixed either fixed to the foundation to the ground or fixed on the top of the tower. So, it is static. Other type of tower crane is traveling, your tower cranes can also be traveling.

Tower cranes can be static or traveling based on their design. Static tower cranes are anchored firmly to the ground, making them stable for high-rise construction but immobile. On the other hand, traveling tower cranes can move along tracks or from truck beds, providing added flexibility while still maintaining a strong base for lifting.

Imagine a dining table that is permanently placed in a room; that would be like a static tower crane. Now, consider a cart that can move around the room; that is similar to a traveling tower crane, which can position itself where needed.

Similarly, the boom of the crane can be classified into horizontal boom and luffing boom. Horizontal means the boom is fixed saddle type where I cannot change the angle of inclination of the boom that is called as horizontal. Luffing means, I can change the angle of inclination of the boom.

The boom, which is the arm of the crane that lifts the loads, can either be horizontal or luffing. Horizontal booms do not allow for changes in their angle, limiting their maneuverability. In contrast, luffing booms can change angles, enhancing the crane's ability to lift loads over obstacles or position them precisely.

Think of horizontal booms like a fixed swing set in a park – it can only swing back and forth at a set angle. In contrast, a luffing boom is like a swing that you can adjust; you can change the height and angle of the swing to fit different play areas.

So, similarly, mobile cranes also can be classified based on mounting, boom type and jib type. Mounting, you can mount it on a truck or a crawler or a ringer base.

Mobile cranes can be categorized based on how they are mounted. They can be truck-mounted for speed and mobility, crawler-mounted for stability and traction on rough terrain, or ring-mounted which allows for rotating the crane around its base. The type of mounting affects how and where the crane can be used effectively.

Picture a mobile crane mounted on a truck like a delivery van loaded with goods, quickly moving from one site to another. A crawler crane is like a bulldozer, with strong treads that navigate across challenging ground, achieving stability during heavy lifts.

Boom type, you can have lattice boom or telescopic boom. Just now, we discussed about the lattice boom. They are lightweight booms. Telescopic or solid booms which are heavier.

Booms are crucial components of cranes and can be categorized into two types: lattice booms and telescopic booms. Lattice booms are composed of interconnected steel pipes, making them lighter and capable of carrying heavier loads due to reduced self-weight. Conversely, telescopic booms extend and retract but are typically heavier, sacrificing some capacity for flexibility.

Think of a lattice boom like a lightweight, foldable tent structure that can support a heavy weight despite being light itself. A telescopic boom resembles a camera tripod that can extend upward, making it flexible for different heights but is bulkier and less weight-efficient.
