Knuckle Boom Mobile Cranes

JOMAC custom builds knuckle boom cranes for each and every unique set of customer requirements. Designed and manufactured at our headquarters and plant in Carrollton, Ohio, JOMAC knuckle boom cranes feature the same special care and craftsmanship as all of our other powerfully light truck bodies and components.

All parts used on JOMAC knuckle boom cranes are sourced from American companies, which means a simpler repair and service process for the life of your crane.

With design and engineering expertise on staff, our team fabricates and builds to the highest standards to outperform the competition. Our knuckle boom cranes feature a worm drive rotation, which translates to a JOMAC crane footprint that is typically much smaller than that of competitive imported cranes and allows our cranes to be mounted just about anywhere when properly reinforced. Such versatility makes JOMAC cranes highly valued for custom applications.

Plus, all JOMAC Knuckle Booms come with a 10-Year Return to Factory Warranty on the structure of the unit. 


More About Knuckle Boom Cranes

Knuckle Boom Cranes can also be referred to as Articulating Boom Cranes or Articulated Cranes. The boom of the crane bends (or articulates) in the center, allowing for a swift back and forth movement of the load. Knuckle Boom Cranes utilize hydraulic cylinders as the source of their lifting power. The utilization of hydraulic cylinders in your knuckle boom crane's construction provides many distinct advantages such as quicker load and faster movement of materials.
