Knowledge Base
How to Choose the Right Knuckle Boom Crane?
Choosing the right knuckle boom crane is crucial to ensure your work efficiency and safety. Here are some key factors to consider to help you make an informed decision:
- Lifting Capacity
First, determine the maximum weight you need to lift. Choose a crane with a rated lifting capacity greater than or equal to your maximum load 1. Keep in mind that lifting capacity typically decreases as the boom extends, so be sure to refer to the crane’s load chart.
- Working Radius/Reach
Consider the maximum horizontal distance you need to lift the load. The working radius of a knuckle boom crane is the distance from the center of the hook to the center of rotation 3. Choose a crane with a working radius that can cover your work area. Consider the lifting height. If you need to move a load to the top of a tall construction project, you will need a crane with a longer reach.
- Other Considerations
Power Options: If you need us to provide power, we can offer electric motor pump stations, diesel engine pump stations, or hydraulic pumps and tanks .
Control Method: You can choose manual control valves or remote controls to operate the crane
FAQ
Frequently Asked Questions
Whether you’re interested in crane installations, loader crane solutions, our team at ZORY is ready to assist.
A knuckle boom crane, also known as an articulating crane, is a highly versatile lifting device. It's characterized by its jointed arm, resembling a knuckle, which allows for exceptional maneuverability in tight spaces. This design makes it particularly well-suited for operation in confined areas such as factories, warehouses, and construction sites.
Knuckle Boom Crane Structure
A knuckle boom crane is primarily composed of the following components:
- Base:Usually mounted on a truck chassis, providing stable support.
- Slewing Mechanism:Enables the boom to rotate 360 degrees continuously.
- Knuckle Boom:Consists of multiple hydraulic cylinders and connecting arms, facilitating multi-angle and multi-directional lifting operations.
- Hydraulic System:Provides power to control the boom's extension, rotation, and lifting.
- Control System:Operators use control valves or remote controls to manage the crane's movements
Yes, a major advantage of knuckle boom cranes is their excellent compatibility with attachments. Thanks to the hydraulic design of their articulated boom, knuckle boom cranes can easily be equipped with a variety of attachments, transforming them into versatile work platforms.
Common Attachments:
- Aerial Work Platform/Basket: Converts the crane into a platform for aerial work, maintenance, etc .
- Grapples: For grabbing various materials like wood, scrap metal, stones.
- Crane Basket: For lifting personnel or tools.
- Auger: For drilling holes, planting trees, etc.
- Winch: For lifting heavy objects below the ground.
Generally, the answer is yes! The flexibility of knuckle boom cranes allows them to be adapted to a variety of vehicles and platforms, but to ensure safe and efficient operation, the following installation requirements need to be considered:
Installation Requirements:
- Chassis Strength:
- Your vehicle chassis must have sufficient strength and stability to support the weight of the crane and its load. This usually requires chassis reinforcement .
- Power Source:
- Knuckle boom cranes usually require hydraulic power. Your vehicle needs to be equipped with a power take-off (PTO) interface to provide hydraulic power to the crane.
- If there is no PTO, Zory can provide an independent power unit, including:
- Electric Motor Pump Station: Suitable for places with power supply.
- Diesel Engine Pump Station: Suitable for places without power supply.
- Gasoline Engine Pump Station: Suitable for micro trucks, etc.
- Installation Space:
- Knuckle boom cranes occupy relatively little space when retracted, but sufficient installation space still needs to be reserved on the vehicle .
- Zory engineers will conduct an on-site assessment to ensure the feasibility of the installation.
