What Is a Knuckle Boom Lift?
A Knuckle Boom Lift is a type of aerial work platform with multiple arm sections connected by joints. These joints allow the lift to bend or “knuckle,” helping it move around obstacles and reach tight spaces. Also known as an Articulating Boom Lift, it offers more flexibility than straight boom lifts.
This machine is commonly used to lift workers and tools to elevated positions for tasks like construction, tree trimming, maintenance, and warehouse operations.

How a Knuckle Boom Lift Works

Key working elements include:
- Hydraulic cylinders for arm movement
- Electric or diesel motor for power
- Joystick controls for easy operation
- Safety sensors and emergency shut-offs
The machine can move vertically and horizontally, making it ideal for complex job sites.
