Folding-arm telescopic crane

Knuckle Boom Telescopic Crane Product Introduction

Product Overview

The knuckle boom telescopic crane is a highly versatile lifting device that integrates both folding and telescopic boom technologies. It offers exceptional flexibility, a compact profile when retracted, and an extended reach when fully deployed. Designed for reliable performance in confined spaces, this crane is widely applied in marine, industrial, construction, and logistics sectors. Powered by hydraulic or electro-hydraulic systems, it ensures stable, efficient, and safe lifting, handling, and installation operations.

Classification & Applications

Classification

By power system: hydraulic knuckle boom crane, electro-hydraulic knuckle boom crane

Working Principle

The crane operates using a hydraulic system that drives cylinders to control boom folding, telescoping, and luffing, allowing adjustable working radius and lifting height. A slewing mechanism enables 360° rotation for full-directional operation. The hoisting winch controls the vertical lifting and lowering of loads. An integrated control system provides smooth motion coordination and includes overload protection, limit switches, and emergency stop functions to ensure safe and stable operation.
