What are Stiff Boom Cranes?

Also known as telescopic or straight boom cranes, stiff boom cranes utilize a hydraulic winch that is raised or lowered by the boom to handle materials. The crane operator can rotate the boom of the crane, extend it, and adjust the height to safely place materials precisely where they need to be. Stiff boom cranes are the ideal choice for gently placing materials and suspending heavy loads in the air for extended periods with little to no drift.

All moving parts of a stiff boom crane are concealed inside the machinery, ensuring that they are safe from the elements and any other sources of potential damage. The moving parts on stiff boom cranes also experience reduced strain when lifting loads because the energy passes through the winch and lift cylinder before reaching the crane structure. This drastically reduces the maintenance requirements of stiff boom cranes, minimizing costly downtime.

What are Folding Boom Cranes?

Also known as loader cranes, knuckle boom cranes, picker cranes, or articulating cranes, folding boom cranes are designed to function similarly to the human finger. By using two booms (main boom and outer boom) attached by a knuckle, these units can move the entire boom structure in and out for exceptional maneuverability even in areas with limited space.

This unique design also allows each unit to fold into a small size when transporting materials or maneuvering through a cramped construction site, allowing you to get to locations that would be inaccessible for other equipment. If your site features an abundance of cramped spaces, overhead obstructions, or other obstacles, a folding boom crane is the perfect solution.
