Load Chart for any crane.

A crane’s load chart is the most important resource a crane operator should understand in order to plan the lift and ensure that loads are positioned where the equipment can safely lift the load and move it to where it needs to be placed.
For example, if a truckload of pipe is positioned too far away from the crane or equipment, it may not be safe to lift the pipe off the truck and place it next to or in the trench.
There are different crane manufacturers out there, like Terex, Liebherr, Grove, zoomlion, tadano… Only load charts that are found in the equipment operation manual or posted by the manufacturer in the equipment should be used. The load charts are specific to the make, model and configuration of a specific piece of equipment.
This section shows the dimensions of the crane, this type of information would be necessary for transportation purposes and for setting the crane up in tight areas.
The values given in the load charts are “Gross Capacities”. The actual load the crane can lift is referred to as the “Net Capacity”. The maximum load must never exceed the crane’s Net Capacity!
The Gross Capacity must include the weight of anything and everything that is mounted or stowed on the boom of the crane or hanging from the boom tip. These are called “Capacity Deductions”.
Capacity Deductions: depend of the manufacturer of the crane. Make sure to understand what the manufacturer determines are capacity deductions. For exemple:
A range diagram is usually included in every chart which illustrates how much boom length is needed to pick up and lift a load both at a distance and at height.
he range diagram is also helpful when setting up near structures. When deductions for the wire rope are required, a good place in the load chart to assist in making calculations for this would be the working range diagram.
The working range diagram to the right is separated into:
