Efficient · Flexible · Reliable --- Redefining Lightweight Material Handling Solutions
YFM telescopic knuckle boom crane is a fully foldable crane that combines the flexibility of an articulating boom with the extendability of a telescopic boom, enabling safe and reliable storage in limited spaces. The flexible articulated boom allows for precise, safe, and efficient material handling. The telescopic boom can achieve longer bow-free extension distances even under heavy loads.
YFM telescopic knuckle boom crane is specially designed for complex working conditions and complies with internationally recognized technical standards (CE, ISO 4301/4306 international standards).
