What is a Knuckle Boom Truck Mounted Crane?
A knuckle boom truck mounted crane is a type of hydraulic crane mounted on a truck chassis. Its design includes a folding “knuckle” mechanism that allows the boom to articulate, providing enhanced maneuverability. Unlike standard telescopic cranes, knuckle booms can reach into tight spaces and navigate obstacles with ease, making them ideal for urban environments and complex job sites.
Key Features of Knuckle Boom Cranes
- Articulating Boom: The boom can bend at knuckle joints, enhancing reach and flexibility.
- Truck Mounted: Mounted on a truck chassis for easy transportation and mobility.
- Hydraulic System: Equipped with a powerful hydraulic system for smooth operation.
- Variable Reach: Capable of reaching various heights and distances depending on the model.
- Compact Design: Ideal for use in confined spaces where larger cranes cannot operate.
