How do you find the boom length of a crane?
The distance is measured from the center pin of the crane to the center of the load. Once you determine the distance, look on that line for the largest capacity; that will indicate how many feet of boom must be extended. In this case, it is 45 feet.
What is the difference between a crane and a boom truck?
These cranes are designed for a construction project’s early stages. They travel on rough terrain with large wheels. Whereas boom trucks can move independently, you must use a heavy haul trailer to transport rough terrain cranes.
Is a boom lift a crane?
At many jobsites boom lifts and cranes are used to reach a working area at height and lift and lower loads. Boom lifts are used to elevate workers and tools, for all kinds of tasks where a safe and stable elevated working platform is needed. …
What are the three functions of a crane?
The main purpose of a crane is to lift extremely heavy amounts of weight. A typical crane is equipped with a hoist rope, wire ropes or chains and sheaves.
Modern day cranes are used for:

What does a mobile crane do?
What is a Mobile Crane? Mobile cranes are designed to use a collection of simple machines in order to both raise and lower objects, as well as to move them horizontally. This type of crane can be easily moved from one location to the next, making it a cost-effective rental option for many construction companies.
How does a hydraulic system work in a crane?
How Crane Hydraulics Work. … The pressurized hydraulic fluid pushes the piston in and out of the cylinder, allowing the piston to lift or move a load. With hydraulic systems in cranes, there are typically two different pistons. When one piston is compressed, the displaced oil forces the other piston to extend.
What is the hook on a crane called?
A lifting hook is a device for grabbing and lifting loads by means of a device such as a hoist or crane. A lifting hook is usually equipped with a safety latch to prevent the disengagement of the lifting wire rope sling, chain or rope to which the load is attached.

How are crane lift plans calculated?
Calculating the Weight of a Load
- Step 1: Determine the Volume of the Load. Rectangle/Square: Volume = Length x Width x Height. …
- Step 2: Determine the Material You’ll Be Lifting. The table below can be used for approximate weight values of common loads and materials: …
- Step 3: Determine the Weight of Object.

How far can a mobile crane reach?
Hydraulic Truck Cranes
Hydraulic trucks range from 30 to 600 ton capacity and feature a hydraulic boom that can reach lengths up to 200 feet.
How is crane boom lifting capacity calculated?
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.
