What is the difference between a Franna and crane?
Franna cranes are named after their original manufacturer. These are pick-and-carry type cranes that can lift loads and carry them directly to their destination. They are not intended to carry or lift some of the larger loads, but they are more versatile than larger mobile cranes.
How do I size a crane?
Here are some key steps:
- Calculate the maximum radius from the center of pin.
- Confirm the total weight of the load.
- Determine clearance issues, either height under ceiling or overhead obstructions.
- Allow for the height of obstructions between crane and load.
- Consider the hook height required with lifting equipment.
How is a cranes radius measured?
‘ indicator on the left axis represents the radius, the distance from the center pin to the center of the load. EXAMPLE: You need to lift a load of 15 tons (30,000 pounds) a distance of 25 feet. The distance is measured from the center pin of the crane to the center of the load.

What type of crane is a Franna?
pick-and-carry crane
What Is A Franna Crane? A Franna Crane is a type of pick-and-carry crane. Similar to a mobile crane, a pick-and-carry crane is designed to travel on public roads. However, the key difference between a mobile crane and a pick-and-carry crane is that a pick-and-carry crane does not have outriggers or stabilizing legs.
How much can a Franna crane lift?
25 tonne
Specifications. The MAC 25-4 is a mobile articulated crane with a maximum lifting capacity of 25 tonne (27 USt). The MAC 25-4 offers maximum safety, excellent roadability, intuitive operation and unmatched versatility.
What does the tonnage of a crane mean?
In general, a cranes tonnage rating is determined by how much weight it can pick approximately 5′ away from it’s center pin. But as you go further away from that point the capacity of the crane decreases. Additionally, the higher you have to lift a piece, the more boom must be pushed out, also reducing capacity.
What does a 500 ton crane mean?
About the 500-Ton Crane The crane has a lifting radius of 100 metres and the load capacity maxes out at 400 tons. In order to become an operator of the 500-ton crane, years of training and practice are required.
What is the length of a crane?
Capacities of an RT crane range from 30 to 130 tons. RT cranes have boom lengths that range between 80 and 140 feet.
How do you calculate crane load?
Measure geometric components
- The standard calculation for maximum crane capacity is (r)(hC)/100.
- R = Radius between the ground and load.
- hC = Lifting height multiplied by the capacity.
