High-Quality 4 Ton Hydraulic Knuckle Boom Truck Mounted Crane

Connected bar mechanism Higher lifting capacity with. Two folding arms Can it upward(negative elevation angle)&enter a lower space for lifting. The second section knuckle boom Cylinder with the reverse arrangement and adopt the flange connection balance value with higher reliability to reduce the leakage point. Rack cylinder We adopted an inclined arrangement, the boom in folding state, to fully use space and compact overall structure—the lower center of gravity and vehicle driving stability.
