Choosing the right lifting equipment can have a major impact on jobsite productivity. Understanding the differences between a hydraulic boom vs. knuckle boom trucks helps businesses select the best equipment for their lifting needs.
While both hydraulic boom and knuckle boom trucks combine mobility with lifting capability, they offer specific features that can complement different types of work. Factors like lifting capacity, reach, maneuverability, setup space, and load placement all play a role in determining which machine is the better fit.
In this guide, we’ll compare hydraulic boom trucks and knuckle boom trucks side-by-side, explain where each excels, and outline how ALL Crane helps customers choose the right equipment for safe and efficient project execution.
Key Differences Between Hydraulic Boom and Knuckle Boom Trucks
Although both are truck-mounted lifting solutions, hydraulic boom trucks and knuckle boom trucks are designed with different priorities in mind. Let’s break down different factors that differentiate both types of equipment.
Boom Configuration
The most obvious difference between hydraulic and knuckle boom trucks is the design of the boom itself.
- A hydraulic boom truck uses a straight telescoping boom that extends outward and upward.
- A knuckle boom truck, also known as an articulating crane, uses a folding boom with multiple pivot points.
These specific features directly impact how these boom trucks are used. The linear nature of a hydraulic boom prioritizes lifting height, whereas the articulating nature of the knuckle boom truck allows the crane to bend around obstacles where needed.
Lifting Capacity
Because of their straight boom design, hydraulic boom trucks typically offer greater lifting capacity than knuckle boom trucks, with capacities of up to 50 USt. Their better vertical lifting potential makes hydraulic boom trucks more ideal for notable loads, such as:
- Heavy construction materials
- Structural steel
- Large HVAC equipment
- Industrial machinery
- Precast concrete
The articulating nature of knuckle boom trucks provides the advantage of multiple pivot points, which does lower the max lifting capacities compared to other equipment. While knuckle boom trucks are usually optimized for lighter loads than hydraulic booms, they still offer considerable lifting capacities.
Reach
Hydraulic booms typically provide superior vertical reach, whereas knuckle booms are a better fit for jobs that demand horizontal reach or projects that require operators to work around structures and other obstacles.
Mobility and Jobsite Access
Both types of boom trucks offer excellent maneuverability and can be driven on roads and highways depending on local laws. They also provide the advantage of not requiring extensive on-site assembly, providing some key benefits for site access.
While both hydraulic and knuckle boom trucks provide similar benefits such as a smaller turning radius compared to all-terrain and truck cranes, hydraulic boom trucks typically require a larger operating footprint than knuckle boom trucks. The more compact boom swing radius and articulated design makes knuckle boom trucks advantageous for:
- Compact setup areas
- Congested urban environments
- Tight industrial sites
- Frequent loading/unloading operations
When to Choose Hydraulic or Knuckle Boom Truck
Both types of boom trucks are excellent options depending on the requirements of your job. While your specific project will dictate which is right for your lifts, there are some general criteria that can make one option better than the other.
Hydraulic Boom Truck:
- Higher lifting capacities
- Greater vertical reach
- Heavy material placement
- Rooftop equipment installation
Knuckle Boom Truck
- Tight-access jobsites
- Horizontal navigation around obstacles
- Precise load positioning
- Frequent loading and unloading
