Introduction
Knuckle boom truck mounted cranes are revolutionizing the way heavy lifting is done in various industries. These versatile machines have become essential for construction, logistics, and even landscaping. Unlike traditional cranes, knuckle boom trucks offer a unique folding mechanism that provides both flexibility and efficiency, making them ideal for tight spaces and challenging environments. This article will guide you through everything you need to know about knuckle boom truck mounted cranes, their features, advantages, applications, and more.
What is a Knuckle Boom Truck Mounted Crane?
A knuckle boom truck mounted crane is a type of crane that is mounted onto a truck chassis, combining the mobility of a truck with the lifting capabilities of a crane. The distinctive feature of a knuckle boom crane is its articulating arm, which allows it to extend and articulate at multiple points, resembling a knuckle. This design allows for increased versatility and maneuverability, making it suitable for various lifting tasks in confined spaces or difficult terrains.
Key Components of a Knuckle Boom Truck Mounted Crane
- Crane Arm: The arm of the crane extends and articulates at several points, enhancing its reach and flexibility.
- Truck Chassis: The base that supports the crane, providing mobility and stability.
- Control System: Typically remote-controlled, allowing the operator to maneuver the crane safely from a distance.
- Hydraulic System: Powers the crane’s movements, providing the necessary force to lift heavy loads.
- Hook and Accessories: Used for attaching loads, often accompanied by various attachments for specialized tasks.
